The food combining system, as a whole, is simple and easy to understand. It logically evolved from the study of gastric physiology and the actions of enzymes and digestive juices. Hygienic food selection and the principles or food combining are based on the nutritional needs of humans and the limitations of our digestive systems. It is not what we eat, but what we digest and assimilate, that determines the nourishment our bodies receive. Food combining is based on the discovery that certain combinations of food may be digested with greater ease and efficiency than others.

Correct food combinations result in an immediate improvement in health by light- ening the load of the digestive organs. Better nutrition is assured, and there is better digestion, less fermentation and putrefaction, more comfort, less distress and less gas. So- called food allergies often disappear as a result of proper food combining. (See article in the Case History section of this lesson. This article was written by Richard Hill, a young man who had to learn the hard way.)

Fermentation causes irritation and poisoning.

For example, some plants contain large amounts of oxalic acid (see definition) and should not be used as food. Many plants which contain smaller (nutritionally insignifi- cant) amounts of oxalic acid are excellent foods. On the other hand, tobacco, which is a plant, contains proteins, carbohydrates, minerals, vitamins and water, which are the con- stituents of food. But tobacco also contains considerable quantities of poisons. Dr. Shel- ton says that one of these is one of the most virulent poisons known to science. There- fore, tobacco cannot be a food.  Nutrients in foods are chemical substances of known composition and structure, classified as carbohydrates (such as sugar, starch and glycogen); lipids (fats); proteins (amino acids linked together); salts (minerals); and vitamins, needed in small quantities (or, traces) by the body. In addition, foods contain indigestible materials—cellulose (fiber).  Water, oxygen and vitamins, together with proteins, carbohydrates, fats and miner- als, form the constituents of the body—the blood, tissue, bones, organs, muscles and so forth. Foods must be taken into the digestive tract and prepared for use by the organism before their constituents may be used by the body.

=== The Best Food Is Raw Food ===

=== The Best Food Is Raw Food ===

In our discussion of food combining, cooked foods and flesh foods will be men- tioned. Uncooked foods from the plant kingdom constitute the ideal Hygienic diet, for those not yet ready to use exclusively raw plant foods, information on food combining of other foods is included. People with impaired digestion may have been advised to avoid raw food. If serious pathological conditions exist, or if there are organic limitations caused by surgery, it would probably be advisable for such people to seek the help of a Hygienic doctor. Most such people can be helped by Natural Hygiene, but some of them may need careful su- pervision in changing from conventional eating and living patterns. People whose digestive impairments limit the use of uncooked food should utilize raw foods to whatever extent they can while they aim for restoration of as much normal function as possible. The rational approach to such restoration of normal function is not drugs or surgery, but rest and fasting, followed by a gradual implementation of improved eating and living practices, adapted to the limitations of that individual. The goal should be the gradual achievement of a diet predominating in uncooked foods, because the nutrients available in raw foods are several hundred percent greater than those remaining after food has been cooked or otherwise processed. More details about the damage done by cutting, cooking, seasoning and flavoring food will be given in future lessons. Raw foods improve the total inner environment. Sluggish bowels begin to move, eventually cleaning out waste that may have been lodged in the folds of the intestine for months. The layer of mucus that forms in the intestines when cooked food predominates is removed, greatly increasing efficiency in the absorption of nutrients. Food wastes don’t stay in the bowel long enough to putrefy. The transit time of raw food in a healthy body is 20 to 24 hours, while cooked food may take three days or longer. Many scientific researchers arid medical doctors now, recognize the value of raw food, both in health maintenance and for improvement or remission in chronic illnesses. John M. Douglass, M.D., internal medicine specialist at the Southern California Per- manente Medical Group in Los Angeles says, “It’s a sad commentary that we think we can compensate with a pill for all the heat-labile nutrients and enzymes that are lost in cooking.” He says also that experience shows that the raw food diet works for many di-  abetics, although it’s not always easy for them to follow and must be planned carefully.

Dr. Paul Kouchakoff, medical researcher of the Institute of Clinical Chemistry, Lau- sanne, Switzerland, revealed circa 1930 that after eating cooked food, the human body develops leucocytosis, the abnormal proliferation of white blood cells. Leucocytes are created and rushed to the intestine. When he fed patients on an 80 percent raw diet, no leucocytosis developed.

The 80 percent raw food diet: For those who are not yet ready, or willing, to change to an all-raw diet, a good start would be the achievement of an 80 percent raw diet. For most people, this is not difficult to achieve. It can be appetizing, interesting, varied, sat- isfying and economical. The information in the two lessons on food combining will con- tain all the details you need about utilizing both raw food and (if you use it) cooked food, so that you may work out your goal of eventually achieving an all-raw diet, even if you must take a roundabout route by first implementing the 80 percent raw diet.

The best and quickest way to achieve an 80 percent raw diet is to never eat cooked food more than once a day, and as part of only one meal. One should try for more and more days on raw food only. Even the people who are coping with digestive problems may eventually achieve these goals as they learn to apply the principles of Natural Hy- giene to their own needs.

Foods vary widely in character and nutritional constituents. In order to intelligently implement the principles of food combining, reference points are necessary. A food clas- sification chart will be included with Lesson No. 23, listing and classifying specific foods. In this current Lesson No. 22, we will classify the broad categories in which foods can be placed. This classification of food categories will provide clarification and greater understanding of our discussion of the principles of digestive physiology and chemistry that decree correct food combining.

For food to be utilized by the body, it must first undergo a series of processes which we call digestion. After we perform the only really voluntary actions involved in the process of nutrition—putting the food into our mouths, chewing and swallowing—the balance of the digestive process is the function of the autonomic or involuntary nervous system.

After we perform the only really voluntary actions involved in the process of nutrition—putting the food into our mouths, chewing and swallowing—the balance of the digestive process is the function of the autonomic or involuntary nervous system.

The changes which foods undergo are largely effected by enzyme and digestive juices. The conditions under which “such action” can occur are sharply defined, and this is the logical foundation of the food combining system. Physiologists have ascertained the details of the chemistry of digestion through long and painstaking labors. It has re- mained for the Natural Hygienists to make practical application of this great fund of vital knowledge. Knowledge of the physiology and chemistry of digestion can lead us all to a food program that will insure better digestion and better nutrition.

# Oxidases,oroxidizingenzymes,arereleasedinthepresenceofoxygenandrapidlybring  about a change in the color of food. They act on foods in the mouth while one is mas- ticating or whenever the food is exposed to oxygen. These enzymes are also present in apples and other fruits. They are released when the fruit is cut and react so as to rapidly bring about, a change of color to brown. It is not necessary to memorize the names of these enzymes, but the information about the, action of the different types of digestive enzymes will help you to understand the underlying rationale of food combining. Each digestive enzyme is specific in its action. It acts only upon one class of food substance. Each stage in the digestion of food requires the action of a different enzyme, and the various enzymes can perform their work efficiently only if the preceding work has been properly performed. Body chemistry is, to a large extent, determined by the the food we eat. When certain foods are eaten regularly, the digestive enzymes and secretions are of a character to han- dle those foods. When the diet is altered, more and more of the digestive juices secreted will be of a character to digest the foods in the new diet, and less and less of the diges- tive juices will be of the character to digest the foods in the old diet. The type of digestive juice fitted for the digestion of one type of food is of no value in digesting another type of food. Therefore, it is essential that food be taken in combi- nations that do not interfere with enzymatic action.

=== The Process of Digestion  ===

=== The Process of Digestion  ===

Digestive speed and efficiency vary with individuals and circumstances. However, certain general statements can be made. Fruits pass through the stomach quickly; low- protein and low-starch vegetables also pass through the stomach rapidly, with little change; vegetables containing much starch must be retained in the stomach longer, for more thorough digestion; and proteins require a still longer time »for gastric digestion. Fruits may remain in the stomach for thirty to sixty minutes, low-protein and low-starch vegetables a little longer, concentrated starches about two hours and concentrated pro- teins approximately four hours. Some foods may take five or six hours or more to leave the stomach. Some examples are combination starch/protein foods like legumes (includ- ing beans), grains, cooked cabbage and flesh foods. Most digestion occurs in the stomach and small intestine. Digestion, especially starch digestion, actually begins in the mouth, with mastication and insalivation of the food. This sends the proper signals for the release of the digestive juices suited to the character of the food eaten. Digestive juices are present in the saliva and in the gastric secretions of about five million microscopic glands in the walls of the stomach. The digestive glands supply different enzymes and juices of varied strength and character and with specific timing, depending on the different foods ingested. The di- gestive juices may be more or less liquid, of varying degrees of acidity or alkalinity and with complex and elaborately contrived variations.

After food is masticated, insalivated and swallowed, gastric digestion is initiated. In- voluntary movements of the stomach slowly mix the food with gastric juices secreted by the glands in the walls of the stomach. Pepsin, a protein-splitting enzyme, and hy- drochloric acid are separated, as well as lipase, a fat-splitting enzyme, mucus and dilut- ing juice, along with other factors needed in the digestive process. An alkaline secretion protects the walls of the stomach from the acids. Mucus is a natural lubricant that is se- creted by the cells of the mucous membranes lining all of the hollow organs of the body. It keeps the body tissues moist and prevents them from drying and cracking.

A brief review of the process of digestion will help in understanding the food com- bining rationale. Gastric secretion is continuous (except during fevers, gastric inflam- mation, pain or strong emotions; fasting is indicated when any of these conditions are present). Of course, gastric secretion is unnecessary when no food is taken.

Hunger and the sight, smell, taste or thought of food stimulate gastric secretion. Usu- ally about three pints of gastric juice is secreted every twenty-four hours and about half this amount is required to digest a hearty meal. If you eat more than two hearty meals daily, your account will be overdrawn.

If you eat more than two hearty meals daily, your account will be overdrawn.

As the process of digestion continues in the stomach and the food is mixed with the digestive juices, water (from the body’s reserve supply) is added to the mixture in a process called hydrolysis. During hydrolysis, digestive enzymes separate carbohydrates into simple sugars, and proteins into their constituent amino acids.

Since digestion is a mechanical as well as a chemical process, some cellulose is an important part of the diet. Although cellulose cannot be digested by humans (no enzyme secreted by humans is capable of splitting cellulose), it serves as bulk in the propulsion of food through the digestive tract. Cellulose also provides the bulk needed in the effi- cient elimination of food residues. Juices and refined foods contain little cellulose. How- ever, too large a quantity of cellulose is also undesirable. Therefore, we should use fresh fruits and, when using vegetables, strive to obtain the young, tender vegetables, as these contain smaller amounts of cellulose.

Food residues, fibrous materials and particles not thoroughly masticated proceed on to the colon. Peristalsis (wave-like muscular contractions) propels the food mixture back and forth in the stomach. Periodically, the most liquid portion of the mixture is discharged into the duodenum where it meets a very acid fluid. The resultant semi-liq- uid mixture, known as chyme, then proceeds further—into the small intestine—where it meets a very alkaline mixture of pancreatic juice, additional digestive enzymes and bile. (Bile is secreted by the liver and stored in the gallbladder to be used when needed, par- ticularly for emulsifying fats).

The intestinal glands secrete a juice containing enzymes similar to pancreatic en- zymes. Virtually all absorption should occur by the time the food passes through the small intestine, and the residue proceeds into the large intestine (the colon).

Through all these processes, the peristaltic contractions continue, longitudinally and circularly, and propel the chyme along the alimentary canal. As you can see, foods are not digested when they have passed out of the stomach. A large part of the work of di- gestion takes place in the small intestine. But the role of gastric digestion is an important one in preparing the food for the next stage in the digestive process.

Digestion is governed by physiological chemistry, and this must be considered in the planning of meals that are compatible with the physiological limitations of the digestive glands and their secretions. This lesson will help in understanding the principle that the digestion of different foods requires digestive juices of different characters.

Starch digestion begins in the mouth with the action of the enzyme ptyalin (alpha amylase) which converts (or else begins the process of converting) starches into sugar during mastication and insalivation. The salivary secretions accompany the food to the stomach and salivary digestion of starches continues in the stomach for a long time, if the food was eaten under correct conditions.

If ptyalin is the only agent in the body capable of initiating starch digestion (and this is not certain), or whether it is simply the body’s first opportunity to initiate starch di- gestion, we must not disregard its importance. The chewing process in the mouth should mix food with saliva, but people have the tendency to swallow the mass too quickly to permit the enzyme to complete its action. This necessitates the continuation of the sali- vary action in the stomach.

It is important that starches be eaten dry, not moist. So, you should eat steamed or baked potatoes dry rather than in potato soup. The eating of liquids with starches pro- motes the tendency to swallow moist starch without thorough mastication, insalivation and emulsification, processes that are particularly needed for the digestion of starches. Drinking liquids or eating liquidy foods softens the food artificially and may also cause you to eat more food than if you had eaten it dry. Drinking at meals dilutes the digestive juices and also prevents thorough mastication and insalivation of the food.

If the ptyalin is destroyed or its action is inhibited and the digestion of starch is in- terrupted, the partially digested (and probably somewhat fermented) starch proceeds to the duodenum, where further starch-splitting enzymes are secreted. Starch that escapes digestion in the stomach may later be acted upon by pancreatic and intestinal enzymes, provided too much fermentation has not already occurred. It is also very possible that the interrupted gastric digestion may never be completed.

Ptyalin requires either an alkaline or neutral medium. Ptyalin is destroyed by even a mild acid. If fruit acids—or any acids—are taken with carbohydrates, especially with such as potatoes, beans, bananas or dates, digestion will be inhibited or prevented and fermentation may occur. Oxalic acid diluted to one part in 10,000 completely arrests the action of ptyalin. Significant amounts of oxalic acid are contained in rhubarb, spinach, Swiss chard, beet greens and purslane.

The acetic acid in a teaspoonful of vinegar can suspend salivary digestion. Tannic acid (in coffee and tea) inhibits starch digestion, as do drug acids. The combination of citric, malic and oxalic acids in tomatoes (which are released and intensified by cook- ing) interferes drastically with starch digestion.

People take oranges and grapefruit as part of a meal that includes cereal and/or bread, later complain that they feel great distress after such a meal and conclude that they can- not eat citrus fruit. Such a conclusion is based on their experience of a wrong combi- nation—not of a wrong food. Fermentation frequently does occur as a result of eating acids with carbohydrates. All students of food combining know that this combination produces bad effects such as gas, sour stomach (hyperacidity) and contributes to great difficulty in digesting starches.

When foods are eaten in such incompatible mixtures, and the efficiency of digestive enzymes is inhibited, it is subjected to decomposition in the digestive tract. If the diges- tive enzymes cannot perform their intended functions of breaking down and hydrolyzing the food (adding water from the body’s reserve supply), bacterial decomposition may occur, resulting in fermentation and the production of alcohol and acetic acid. Sugar, particularly, will readily ferment into alcohol, especially when combined with acids or protein. Natural combinations of citric acid or malic acid or other natural fruit acids combined in the whole fruit with fructose (also called levulose or fruit sugar) do not cause fermentation unless eaten with starches.

Fermentation is the decomposition of sugar and starch, and their conversion by mi- croorganisms into carbon dioxide, alcohol and acetic acids. Dr. Shelton says that diges- tion reduces food to the diffusible state without depriving it of its organic qualities, while fermentation renders food diffusible by reducing it to an inorganic and useless state. Di- gestion puts food in a solution, but fermentation disintegrates it.

A simple way to avoid production of these poisonous substances in the digestive tract is to learn, and implement, the Hygienic rules for food combining. They are perhaps of even greater importance than food selection. Persistent adherence to food combining principles has been known to reduce, or even eliminate, many digestive, nasal, skin and other problems, even in some people who have not changed to the Hygienic diet. It is obvious that elimination of incompatible food combinations is a giant step in the right direction. Efficient digestion and good health can be possible only when we eat in such a way as to offer the least hindrance to the work of digestion.

=== Protein Digestion ===

=== Protein Digestion ===

The digestion of carbohydrates is so different from that of protein that, when they are mixed in the stomach, they interfere with the digestion of each other. Protein diges- tion starts in the stomach and acid enzymes are secreted when protein is eaten. Proteins require an acid medium for digestion so, upon ingestion, hydrochloric acid is secreted in order to activate pepsinogen; this immediately stops the digestion of starches.

Almost all foods contain some protein but, when we speak of protein foods in our study of food combining, we are referring to concentrated proteins like nuts and seeds, cheese, flesh foods, etc. (See Classification of Foods in Lesson No. 23 for help in iden- tifying concentrated protein foods, concentrated carbohydrate foods, etc.)

The normal digestion, absorption and metabolism of protein requires thorough mas- tication of food, in order to break it down for propulsion through the digestive tract, and for action by the digestive enzymes. As previously indicated, hydrochloric acid and pepsin (and other acid gastric juices) are secreted for the initial phases of protein diges- tion in the stomach, and other enzymes, such as trypsin, continue the digestion in the small intestine in a slightly alkaline medium. Protein-digesting enzymes are also secret- ed by the pancreas.

Before the body can use proteins, they must be reduced to their constituent amino acids (the building blocks of protein). The body must break down the complex proteins in foods and synthesize its own protein out of the amino acids. Food combining rules are of major importance in the consumption of protein, since the complexity of this food element would seem to suggest that it be eaten only under ideal conditions.

Free hydrochloric acid to the extent of only 0.003 percent is sufficient to suspend the starch-splitting action of ptyalin. Only a slight further increase in acidity not only stops the action, but destroys the enzyme. All physiologists agree that even a mild acid de- stroys ptyalin. It has never been shown that saliva is capable of digesting starch without the presence of ptyalin.

The function of the gastric protein-splitting enzymes, such as pepsin, are prevented by an alkali. The physiologist Stiles says, “The acid which is highly favorable to gastric digestion is quite prohibitive to salivary digestion. The power to digest proteins is man- ifested only with an acid reaction and is permanently lost when the mixture is made dis- tinctly alkaline. The conditions which permit peptic digestion to take place are, there- fore, precisely those which exclude the action of saliva.”

=== Combination Foods ===

=== Combination Foods ===

Single articles of food that contain starch-protein combinations (grains, legumes, and a few others) are less difficult for the body to handle than when two foods are eaten with opposite digestive needs. The body is able to adjust its juices, both as to strength and timing, to the digestive requirements of combination foods. The first response by the body is the releasing of an almost-neutral juice for digestion of the starch. After gas- tric digestion of starch is completed (about two hours), hydrochloric acid is secreted for digestion of the protein. The two processes do not go on simultaneously—rather, the se- cretions are minutely adjusted, in both character and timing, to the varying needs of the body to digest the complex food substance.

Beans: “Because of their complex character, beans, a protein-starch combination, tax the digestive powers more than simpler foods, but the gas, discomfort and other trouble that so commonly follow, eating them is not due so much to the beans themselves as to the company they keep. Baked beans are preferable to beans that are boiled and taken saturated with water. If taken thus relatively dry, well chewed and eaten in proper com- binations, beans are readily digestible.” This article about beans, which was published by Dr. Shelton in 1971, is evidently a somewhat revised opinion. In his Volume II of The Hygienic System, published in 1935, he suggested that beans should not be used.

I personally was formerly unable to tolerate lentils or beans of any kind, even when sprouted. I eliminated all legumes from my diet for about six months, after which I carefully experimented with small amounts, properly combined, until I seemed to build up my ability to digest them. Today I can eat sizeable servings of cooked or sprouted legumes (which I seldom do) and I have no problem with them.

=== Foods with Different Digestive Requirements ===

=== Foods with Different Digestive Requirements ===

When two foods are eaten that have different or even opposite, digestive needs, the precise adjustment of digestive juices to meet requirements becomes impossible. Eat- ing proteins with carbohydrates (sugar or starch) produces the same abortive situation as combining acids with carbohydrates, since protein digestion requires the secretion of acid enzymes and juices. All acids, including those in food and the acid protein-digest- ing juices, destroy ptyalin, the starch-digesting enzyme.

Arther Cason, M.D., D.P.H., F.R.S.A. (London), writing in the April, 1945 issue of Physical Culture, mentions two groups of experiments made by him and his aides which showed that eating protein and carbohydrate at the same meal retards and even pre- vents digestion. He made control tests in which digestive rates were recorded, and a final analysis of the feces was made. He says, “Such tests always reveal that the digestion of proteins when mixed with starches is retarded in the stomach; the degree varying in dif- ferent individuals, and also in the particular protein or starch ingested. An examination of the fecal matter reveals both undigested starch granules and protein shreds and fibers, whereas, when ingested separately, each goes to a conclusion.”

As indicated by Dr. Cason, there is an individual variation in the response to certain food combinations. This would seem to account for the fact that certain people exhibit overt symptoms from the use of certain food combinations, while others do not. Howev- er, the mere fact that overt symptoms are not observed is not proof, per se, that the food is being properly utilized.

Potatoes are said to be the least objectionable of any starch to be used with protein. Dr. Shelton is of the opinion that it is the rapidity with which potato starch digests that makes its combination with protein less objectionable than the combination of other starches with protein. Potato starch digests in ten minutes under ideal conditions and it would seem that the potato starch digests before the gastric juice can accumulate in quantity sufficient to interfere.

# Never consume two concentrated proteins at the same meal. Two concentrated proteins of different character and composition (such as nuts and cheese) should not be combined. Gastric acidity, type, strength and timing of secretions for various proteins are not uniform. Since concentrated protein is more difficult to digest than other food elements, incompatible combinations of two different concentrated proteins should be avoided. Some people with impaired digestions find it necessary to limit themselves to only one variety of nuts/and or seeds at a sitting, but other people may find, upon experimentation, that two or three varieties of nuts or seeds may be used at the same meal, if desired.

=== Protein-Fat Combinations ===

# Do not consume fats with proteins. Our need for concentrated fat is small and moil protein foods already contain a good deal of fat. Most nuts contain about 10 percent to 20 percent protein, and about 45 per- cent to 70 percent fat. Avocados contain about 1.3 percent protein (Florida varieties) to about 2.2 percent or a little more (California varieties) and 11 percent to 17 percent fat. Most other protein foods are high in fat, including cheese, eggs and flesh foods. The on- ly protein foods not high in lat are legumes, skim milk cheese and lean meat. Fat has an inhibiting influence on digestive secretion and lessen the amount and ac- tivity of pepsin and hydrochloric acid, necessary for the digestion of protein. The fat may lower the entire digestive tone more than 50 percent. Since most proteins already contain a good deal of fat, it would certainly be contraindicated to add more to the meal.

# Fats also delay the digestion of other foods and, if used with starch, it will delay the passage of the starch from the stomach into the intestine. Fat not only inhibits the secre- tion of gastric juice—it also inhibits the physical actions of the stomach. Too much fat taken with a meal results in acid eructations and a burning sensation in the throat. When fats (avocados or nuts) are eaten with green vegetables, preferably raw, the inhibiting effect of fats on gastric secretion is counteracted and digestion proceeds quite normally. The use of fat (avocados) with starch is considered acceptable, provided a green salad is included in the meal. Avocados: Though not a high-protein food, avocados contain more protein than milk. They are high in fat and the small percentage of protein they do contain is of high bio- logical value. They are best used with a salad meal. Since they are so high in fat that they tend to slow down the digestion of foods normally requiring a shorter digestion time, they are perhaps only a fair combination with subacid and acid fruit. They are usually considered a poor combination with sweet fruit, especially dried sweet fruit. However, let us consider some recent work on this subject. In an article on this topic, Dr. Vetrano says that exceptions may sometimes be made in combining avocados with fresh sweet fruit, such as bananas, but that avocados should not be combined with dried sweet fruit, unless it has been soaked overnight. She also says, “Eating avocados with salad enhances their digestion. The next best combination for the avocado is taking it with subacid or acid fruit. The fat in the food does not seem to interfere with the emptying time of the stomach and we have excellent results with this combination. The protein, which is about 2.1 to 2.5 percent, is not sufficient to inter- fere with the digestion of fruit. It is even better when lettuce leaves and celery are eaten with the fruit and avocado. By diluting the fats and the sugars with the lettuce, the emp- tying time of the stomach is not depressed. Those who have weak stomachs with poor muscle tone would probably do better by taking avocado only with vegetable salads. If lettuce is taken with a sweet fresh fruit and avocado, even these digest well. It is probably best to never combine avocado with sweet dried fruit unless it is just a small amount of both eaten with a great deal of vegetables.” Since the avocado is low in protein, it may also be used with potatoes or other starch foods. Some people like to use avocado with the potato instead of using butter. However, I must reiterate, the best way to use avocado is with the salad.

# Do not eat acid fruits with proteins. Citrus, (tomatoes: see discussion), pineapple, strawberries and other acid fruits should not be eaten with nuts, cheese, eggs or meat. Acid fruits inhibit the flow of gastric juice. The digestion of protein requires an unhampered flow. This is one rule that has given rise to some disagreement and controversy. Although Dr. Shelton includes in this rule the prohibition of citrus and tomatoes with nuts and cheese, he goes on to say that nuts and fresh cheese do not decompose when used with acids, but have their digestion delayed. He also says that acids do not inhibit the flow of gastric juice any more than does the oil of nuts or the cream of cheese. Many Hygienists use tomatoes with nuts and believe they cause no problem. Citrus fruits present a different situation, due to the sugar in the fruit, which can ferment if its digestion is delayed by the nuts. Various experiments with the use of citrus fruits com- bined with nuts have produced differing results. Some Hygienists continue to use citrus with nuts. If sweet oranges are used at the same meal with nuts, the precaution of waiting thirty to sixty minutes after eating the citrus is sometimes observed. Grapefruit might be better suited to combining with nuts, since it usually has a much lower sugar content. Citrus fruit is best used alone but may be combined with other acid fruits; nuts are best used with salad. Dr. Shelton modified this rule somewhat on Page 52 of Food Combining Made Easy: “Although green vegetables form the ideal combination with nuts, acid fruits form a fair combination with these foods and may be taken with them.” Dr. Percy Howe, of Harvard, says: “Many people who cannot eat oranges at a meal derive great benefit from eating them fifteen to thirty minutes before the meal.” Dr. Vetrano is convinced from her experience at the Health School that nuts should not be used with citrus fruit and she discontinued this practice some years ago. A corollary of this same subject is the use of some subacid fruits with nuts or cheese- primarily tart or semi-sweet apples, although some other fruits which are usually considered subacid are sometimes used in this way. The same principles would apply as with the use of oranges with nuts, provided the sweeter subacid fruits, such as Delicious apples, are not used. Such acid-protein combinations as sour salad dressings and acid fruit drinks used at conventional meals serve as a check to hydrochloric secretion.

# Do not eat acid fruits with proteins.

Citrus, (tomatoes: see discussion), pineapple, strawberries and other acid fruits should not be eaten with nuts, cheese, eggs or meat. Acid fruits inhibit the flow of gastric juice. The digestion of protein requires an unhampered flow.

 

This is one rule that has given rise to some disagreement and controversy. Although Dr. Shelton includes in this rule the prohibition of citrus and tomatoes with nuts and cheese, he goes on to say that nuts and fresh cheese do not decompose when used with acids, but have their digestion delayed. He also says that acids do not inhibit the flow of gastric juice any more than does the oil of nuts or the cream of cheese.

 

Many Hygienists use tomatoes with nuts and believe they cause no problem. Citrus fruits present a different situation, due to the sugar in the fruit, which can ferment if its digestion is delayed by the nuts. Various experiments with the use of citrus fruits combined with nuts have produced differing results. Some Hygienists continue to use citrus with nuts.

 

If sweet oranges are used at the same meal with nuts, the precaution of waiting thirty to sixty minutes after eating the citrus is sometimes observed. Grapefruit might be better suited to combining with nuts, since it usually has a much lower sugar content.

 

Citrus fruit is best used alone but may be combined with other acid fruits; nuts are best used with salad.

# Donotcombinesweetfruitswithfoodsthatrequirealongdigestivetime-foodssuchas proteins, starches and acid fruits. The sugars in sweet fruit should be tree to leave the stomach quickly, in perhaps fif- teen or twenty minutes, and are apt to ferment if digestion is delayed by mixture with other foods. Sugar-starch combinations cause additional problems. When sugar is taken, the mouth quickly fills with saliva, but no ptyalin is present. Ptyalin is essential for starch digestion. If starch is disguised by sugar, honey, molasses, syrup or sweet fruit, the signals are scrambled and digestion is impaired.

Monosaccharides and disaccharides ferment more quickly than polysaccharides. (See definitions) No digestion of sugars takes place in the mouth or stomach; fermentation is inevitable if sugars of any kind are delayed in the stomach awaiting the digestion of starch, protein or acid fruit.

# Eat but one concentrated starch at a meal. This rule is probably more important as a means of avoiding the overeating of starch- es than as a means of avoiding bad combinations. But it is true that starch foods may dif- fer greatly. If two different starches are eaten together in small quantities, this is thought to not cause problems. Slightly starchy vegetables may be combined with more starchy vegetables (e.g. car- rots with potatoes), but not with combination foods (starch/protein foods) such as grains and legumes.

There is no sharp line of division between subacid fruits and sweet fruits. When us- ing subacid fruits with sweet fruits, it is best to use the sweeter varieties of subacid fruit. The subacid fruits are those that possess a slightly acid flavor (but not tart), such as pears, certain apples, grapes, etc. Grapes, for example, can be acid, subacid or sweet. The sweet fruits are those that are rich in sugar and taste sweet-bananas, persimmons, sweet grapes, and so forth, and all dried fruit. Some people prefer to eat bananas alone, but most people have no difficulty in com- bining them with subacid and other sweet fruit at a fruit meal. Dr. Shelton says, “While I have found that bananas combine fairly well with dates, raisins, grapes and a few other sweet fruits and with green leafy vegetables, such as lettuce and celery, I have noted that they digest best if eaten alone. This calls, to mind the fact that Tilden, also, after much testing of the matter, reached the conclusion that bananas are best eaten alone.” Dried sweet fruits should be used sparingly. Use but one kind at a meal, in small amounts, combined only with subacid fruit and/or fresh sweet fruit and/or with lettuce and/or celery. Overeating of dried fruits .will often bring on symptoms similar to a “cold”. The sugar concentration is naturally greater in fruits which have been dried.

Some dried fruits, esp. dried apricots, should be soaked overnight to replenish the miss- ing water. Dates are usually used without soaking, figs or raisins can be used either way. If they are rather hard, soaking will soften and improve them.

Dr. Vetrano recommends using as little soaking water as possible, soaking one side at a time, so all water will be absorbed, thus avoiding loosing flavor and nutrients. It is important that the water used for soaking be distilled water.

# Do not combine fruit with any vegetables except lettuce and celery. It is best not to combine fruits with vegetables (especially cooked vegetables), pro- teins or starches because if such a combination of food is eaten, the digestion of the fruit will be delayed and subject to fermentation. Lettuce and celery, however, may be com- bined with any fruit except melon, and will cause no problem. Dr. Vetrano says, “Taking green uncooked vegetables with a fruit meal is perfectly all right. Even though some charts state that subacid and sweet fruits combine fair to poorly with green uncooked vegetables, the feeding practices at the Health School indi- cate that these are good combinations, indeed, even enhancing digestion of the fruit in some conditions of impaired digestion.”

The green leafy vegetables combine very well with most other foods. They are excellent food and should be used in the diet. Lettuce and other green and non-starchy vegetables leave the stomach with little change—they pass through the stomach rapidly unless delayed by oily dressings or foods that require a more thorough gastric digestion. Lettuce and celery are good combination with fruit because all of these foods require little gastric digestion. However, even if these vegetables are held up in the stomach with other foods, as when using salad with nuts, there is no fermentation. Eating a large salad of fresh raw vegetables (three or four varieties) daily is an excellent practice. Dr. Shelton says, “A large bowl of salad each day is required by everyone.”

# This rule has been somewhat under question in recent years. I personally have found that eating melons alone is an excellent practice, and have even found it advisable not to mix two different varieties of melon at the same meal. Many people who have complained that melons did not agree with them have no trouble handling them when eating only melon at a meal. Yet, certain Hygienic profes- sionals are offering some post-fasting people more than one variety of melon at a meal (even melons in combination with grapes or other subacid fruit) and some Hygienists follow this practice. If you want to experiment with these combinations, do it sparingly and carefully. But if you have a history of digestive problems, don’t do it at all.

Melons are more than 90 percent liquid and leave the stomach quickly if not delayed and fermented by combining with other foods. Dr. Vetrano says, “Melons are best taken alone because the sugar and other nutriments are in a less stable form than the nutrients of other fruits. Orange juice may be kept in the refrigerator for an hour with little change in flavor, but if you refrigerate watermelon juice for only ten minutes, its flavor, color and composition markedly change. It decomposes much more quickly than other fruits. Consequently, if it is held in the stomach awaiting the digestion of other foods, it will decompose (ferment) and cause a great deal of gastric distress. Eating watermelon with nuts can really be troublesome.”

Other sprouts should properly be classified in the same category as the original seed, even though the sprouting process has somewhat lowered the protein and carbohydrate content.

During the sprouting process, the carbohydrate and protein components of the sprouting seed tend to diminish, and the composition becomes more like a green veg- etable instead of a legume, grain or seed. However, this is not uniformly the case. Sprouts which progress to the green leaf stage, such as alfalfa and mung beans, are high in chlorophyll, and alfalfa sprouts, particularly, may be freely combined as a green veg- etable. Mung bean sprouts still retain enough of the property of legumes so that they are best eaten without other proteins or starches. These sprouts may be included in the low protein/starch category.

Lentils, soybeans, garbanzos and other miscellaneous beans and grains should be al- lowed to sprout only very briefly, until just a small sprout is showing—no longer than the seed, at most. The change in character is therefore much less than for those sprouts which are sprouted to the green leaf stage. Sprouts are high in protein in these early stages. They should therefore be classified, with some expectations, according to their original food categories, namely, as protein or combination protein/starch foods.

It is important to remember that all of the senses have a role in digestion. Seeing, smelling, touching, tasting—and even thinking about food—all help in sending the proper signals for the secretion of the digestive juices and their adaptation to the character of the food.

Complicated mixtures of food interfere with this process of digestion, make it less efficient and may cause digestive problems. When we compound the problem by adding seasonings, the true taste of the individual foods is further disguised. This makes it ex- tremely difficult for the digestive system to supply secretions that can cope with such meals and digestion is inhibited and impaired.

== Question & Answers ==

== Question & Answers ==

I’ve heard that food combining is an individual matter. Why can’t I ignore it unless and until I have symptoms? That’s the rationale of many people, especially people who stay on conventional diets and eat junk foods. Is it better to avoid damage to your body, or would you rather wait until damage is done, and then try to correct it? Most people already have damaged their bodies long before symptoms appear. It would be much more prudent and sensible to take the best possible care, as soon as you can, of the only body you will ever have in this life, rather than to wait until the road back is long and arduous, and when you would probably have to start with a prolonged fast. You say an occasional deviation is not too important. How often is occasional? “Occasional”, or infrequent, means different things to different people. A man once said to me, “I eat meat occasionally,” and when I asked him how often, he said he eats it once a day. If you do something unwise even once a week, I would call that regularly rather than infrequently. Once a month is less frequently, of course, and might be tolerated fairly well by a healthy body. Actually, the degree of harm- fulness of a dietary indiscretion depends on the extent of your deviation and the state of your health. Are you speaking of bending the food combining rules, or do you mean going to a restaurant and gorging on a conventional meal? And, what is even more important, can you afford to deviate? If you are having problems, you would be foolish to do things that can only make those problems worse. For most people who feel they can “afford” to “deviate” “occasionally”, it would be best to save such deviations for occasions when they find themselves in unusual situations when such a choice is the lesser evil. You say not to have more than one concentrated food (protein, starch, sweet fruit) at a meal. Is it all right to have some meals without any concentrated food? Yes, an excellent choice for the first meal of the day (for most people) is melon or juicy fruit only. Yet, some concentrated foods, especially concentrated proteins, have a place in the food program (See Mono Diets, Lesson No. 23). Starch meals are less important, and dried sweet fruit should be used sparingly. Including con- centrated protein foods (usually nuts and seeds) in some of the meals enables the body to obtain a balance of the nutrients it needs. (See sample menus, Lesson No. 23) I seem to lose weight on an all-raw-food diet, but hold a better weight if I eat some cooked food. Usually, persistent adherence to an all-raw-food diet eventually results in im- provement of assimilation, and one gradually puts on, and retains, more weight. However, if you have a tendency to be thin, or if some impairments cannot be completely overcome, you may have to settle for a leveling off at a weight lower than you prefer. If you feel well, the best thing to do is ignore your weight. In some in- stances, for emotional or physical reasons, it may be advisable to use a small per- centage of cooked food. But most people will be much better off if they can decide to stay with an all-raw-food diet. Those who are convinced that they maintain better weight, feel better or have more energy if they use some cooked starches, legumes or grains, will probably be happier on an 80-90 percent raw-food diet.

Yet, some concentrated foods, especially concentrated proteins, have a place in the food program (See Mono Diets, Lesson No. 23). Starch meals are less important, and dried sweet fruit should be used sparingly. Including concentrated protein foods (usually nuts and seeds) in some of the meals enables the body to obtain a balance of the nutrients it needs. (See sample menus, Lesson No. 23)

 

I seem to lose weight on an all-raw-food diet, but hold a better weight if I eat some cooked food.

 

Usually, persistent adherence to an all-raw-food diet eventually results in improvement of assimilation, and one gradually puts on, and retains, more weight. However, if you have a tendency to be thin, or if some impairments cannot be completely overcome, you may have to settle for a leveling off at a weight lower than you prefer. If you feel well, the best thing to do is ignore your weight. In some instances, for emotional or physical reasons, it may be advisable to use a small percentage of cooked food. But most people will be much better off if they can decide to stay with an all-raw-food diet. Those who are convinced that they maintain better weight, feel better or have more energy if they use some cooked starches, legumes or grains, will probably be happier on an 80-90 percent raw-food diet.

Perhaps I was vain, but having my face covered with red, or red and yellow oozing lumps made me a little self-conscious and depressed. The old platitude, “Beauty comes from the inside” sounded nice, but talking with people and FEELING their eyes on the big “honker” on my nose or that “headlight” on my chin didn’t do much for my self- confidence, especially if I was talking to a girl I was hoping to impress. All this may sound like teenage trauma. But I was almost 27 years old and things were worse than ever. This wasn’t my only problem. I was plagued with hay fever, migraine headaches, prostate trouble, poor vision and several other complaints. But my pizza-like complex- ion was my main concern and secret shame.

After 14 years of this “teenage” malady I was depressed and baffled. There was noth- ing I (or anyone else) could do for me. The slow but sure disfigurement I was stuck with was something I couldn’t accept. Only fellow acne sufferers will understand my desper- ation and secret anguish. I’ve talked with many grossly fat people, asking if they would trade their excess weight for a chronic skin condition. So far not any would even consid- er it. And many of these people had contemplated suicide over their weight.

I really had given it my best shot. I had applied gallons of Clearasil, Oxy 5, 10 and 15, washed with Stridex, alcohol, witch hazel, distilled water and special skin soaps and cleansers. I washed many times a day. I was a voracious reader and tried every method and treatment I could find in those 14 long years. I was given various prescription drugs by dermatologists. The labels warned of dangerous side effects. Sometimes I would get temporary relief, usually not.

Next I tried health food store “cures.” I developed a library and gathered glib knowl- edge from all the “experts” and their methods. I hunted down all the herbs (red clover, golden seal, cayenne, etc.) supposed to cleanse the system. I drank them from morn- ing ‘til night. I drank a half-gallon of carrot juice each day. It turned my palms orange, but did nothing for my skin. I did various other juice combinations. They did nothing. I stopped eating chocolate, nuts, fried foods, white sugar, white flour. I even gave up all fruits for a year.

I graduated from Clearasil and smeared my face with green, red and yellow clays, separately and in combinations. I took activated yeast every morning just before my vi- tamin ritual. I was assured my problem was a vitamin/mineral deficiency as well as an unclean system. I took megadoses of A, B complex, C (with bio-flavonoids and Rutin), D, E, folic acid, K, multi-minerals, chlorophyll, wheat germ oil, brewer’s yeast, lecithin and protein powders, using my handy pocket pack. The few times I forgot caused me as much anxiety as the heart patient who forgets his nitro-glycerine.

Then I began to “fast.” I took so-called “juice fasts,” ones with products designed to clean out my colon. I took enemas of warm watery cold water, herb water and distilled water. I drank gallons of water to flush out my system. I tried “organic blood salts” and several other surefire cures. I was getting plenty of fresh, Los Angeles air and sunshine.

Next I got serious. I had said I’d pay a million dollars to solve my problem. Now I began to pay it on the installment plan to a young chiropractor into “natural healing.” I got adjusted, x-rayed, diagnosed as having adrenal stress, given new vitamin/diet com- binations. I took the glucose tolerance test and was diagnosed a hypoglycemic. (Since

I was as bad off as ever and switched to an older naturopath/chiropractor. He put me back on fruit, different vitamins and juices. When this didn’t work he hit the problem with everything he had—more adjustments, x-rays, ultrasound, cold packs, hot packs and, finally, colonic irrigations with and without oxygen! I took these three times a week. It was expensive and embarrassing. But I was determined to get well or die trying. I was that desperate. After all the discomfort and expense my complexion was worse than ever.

I didn’t give up hope. I returned to my library and came across a little book I hadn’t paid too much attention to. It had seemed technical and too different. It was called Food Combining Made Easy by Dr. Herbert M. Shelton. Having nothing to lose, I tried this silly thing. Within a week my face started to clear up. It continued to get better. I stopped the colonics, adjustments, ultrasound and all the other things. Looking for more books by Dr. Shelton, I found Fasting Can Save Your Life at a health food store. I ordered more Shelton books from Natural Hygiene Press. I began to understand the basic ideas of Nat- ural Hygiene and dove in with both feet. It was working where nothing else had. I gave away my vitamins and herbs, got back to 2 or 3 meals a day (from 5 and 6). I washed only with warm water.

I knew I had stumbled onto a new way of life and found people with no cures to sell. They had an understanding of the laws of life. They had a system where one can return to harmony with these laws and achieve total health. I made arrangements to fast under the supervision of Dr. Virginia Vetrano. I fasted at the Chateau Des Sages for 14 days. I listened to lectures and tapes and I learned more about Natural Hygiene. I wanted what these people had. I returned home with my skin more clear than it had been in 14 years. My hay fever and migraine headaches also were gone. At last my search was over and I reached the happy-ending.

I wish I could stop here saying everything was fine. But, I had more learning to do! I stayed with the Hygienic program for three months with never a pimple or sniffle. I thought I was “cured.” I began to stay up late and “just this once” eat wrong food com- binations. Within five months I was living worse than before I had discovered Natural Hygiene, junk foods and all. “Clear Skin!

I thought I was “cured.” I began to stay up late and “just this once” eat wrong food combinations. Within five months I was living worse than before I had discovered Natural Hygiene, junk foods and all. “Clear Skin!

Anything Goes!” I was headed for a fall and I fell hard. It wasn’t easy to start back. But after some bad acne days, I was able to get back on the Hygienic Path. This was, in part, with the help of a certain anonymous group of overeaters. They gave me the tools to deal with the mental blank spot that preceeds that first compulsive bite. Thanks to them I found my way back and everything cleared up again. I learned that I’m never “cured,” but only healthy so long as I obey those Unbending Laws of Life.

I hope anyone with a similar, or any, health problem will take time to look into Nat- ural Hygiene. I had to try everything else first. Maybe someone out there, who reads this, will be able to skip some disappointments and start in on a new, healthy life. I’ll be glad to talk and write and answer questions for anyone who asks for help. This way, by passing the word along, I hope to pay back a little of the joy I have received through Natural Hygiene.

I have never liked the term “The Hygienic Diet.” It implicitly suggests a diet designed for everyone which is specific, inflexible and stereotyped. Hygienically, diet represents a means of affording the organism adequate nourishment and, in order to accomplish this, there may be a thousand different diets which will provide the necessary materials of use in adequate proportions. Diet is merely a vehicle that provides the nutrients the body requires for the maintenance of its health and life. Diet does not cure disease. Diet

per se does nothing. It is passive. It is acted upon by the organism. The purpose is to secure from it the necessary nutrients the body needs for growth, development, repair of wear and tear, reproduction and the maintenance of its functions. To speak as though diet performs some function by itself is erroneous. There is no such thing as an eliminat- ing diet, implying in some way that diet is responsible for elimination. Elimination is a physiological process; it is performed by the organism, not by the food it consumes.

A diet should consist of those materials that are essential to the organism’s survival. These may be broadly classified into proteins, carbohydrates, fats, minerals and vita- mins. Providing that all of these are secured in adequate amounts, in a form which is usable, the organism will have the necessary materials to work with. If they are supplied deficiently or excessively, nutritional stresses will be incurred. To the extent that they are excessive or deficient, consequences will accrue depending upon the activity of the individual organism. Obviously there are considerable limits of toleration, varying from one individual to another. The organism can tolerate slight excesses and occasional de- ficiencies, at these times drawing upon its own nutritional reserves, but prolonged defi- ciencies and substantial excesses will incur consequences of malfunction.

The means whereby the various materials that the organism requires for its health and life are supplied are not of prime importance. Of first importance is the fact they are supplied. This does not mean that we can take refined and processed foods as being good sources of the materials that we require. What it does mean is that, providing the nec- essary materials are available to the organism in the diet consumed, free from noxious extraneous substances, in a form which naturally occurs, not tampered with by the food refiner and processor, the organism will be securing the necessary nourishment. It is im- portant that we get away from the idea that specific foods and specific diets have healing properties or have special properties other than the mere presence of nutrients needed by the organism. The idea that we should take beet juice for anemia, cabbage juice for ulcers or parsley for the kidneys is a vicious reactionary hangover from the medicating superstition. Nor is it desirable that we study the analyses of various foods and select our diet according to some chart which indicates that a particular food is rich in a particular nutrient. This is not good nutrition. From this practice we may learn that wholegrain ce- reals are rich in iron but we may not discover that the presence of phytates renders the iron unavailable to the organism.

We should attempt to secure our nutrients from a wide variety of foods although ob- viously not at the same meal. Over a period of time, eat as wide a variety of foods as is practicable. Introduce new foods into the diet. I am speaking here of course of natural foods and by that I mean foods that are provided by the plant or tree in nature, i.e. fresh fruit and vegetables. In fresh fruits and vegetables, I also include nuts which are botan- ically classified as fruits. Some of the nuts which are in common use are not, strictly speaking, nuts. The peanut is a legume. However, if we select our protein from almonds, brazils, hazels, macadamias, pecans, pine nuts, pistachios, walnuts, etc., these will sup- ply the essential amino acids required for growth, development, repair and reproduction. To avoid any argument about the importance of taking all of the necessary amino acids at the same meal, eat a variety of nuts, but be careful not to overeat. An amount of 3 to 4 ozs. daily is quite adequate. Some additional protein will be taken in the small quantities present in fruits and vegetables. In some cases this might be quite significant. It is desir- able to keep one’s diet simple, not to have a wide variety of foods at a single meal, but to limit the variety to perhaps four different types together with some concentrated food such as nuts for protein.

Many people can survive quite well on two meals a day. One fruit meal and one somewhat large salad meal together with protein. This does not mean, however, that one cannot have two fruit meals or two salad meals. It may be varied as desired. Two fruit meals may be taken one day and two salad meals may be taken another day. If one is on a 3-meal-a-day program, a fruit breakfast is usually the most desirable, but there is no real objection to a salad breakfast; For the remaining two meals, these may comprise a

Basically the Hygienist is arguing that the natural diet of man is comprised of fresh uncooked fruits and vegetables (which includes nuts) and insofar as he deviates from this, he increases his chances of incurring trouble. Dairy products, cheese, yogurt, milk, eggs, butter, rep- resent compromises and if taken at all should be used sparingly. Flesh such as meat, fish and fowl represent a departure from food normal to man. The arguments in support of this are involved and extensive and it is not appropriate for me to discuss them here, but it is incumbent upon me to state categorically that flesh foods do not constitute a part of the normal diet of man. Their use then represents a compromise. The extent to which one compromises, and by this I mean the extent to which one consciously and volition- ally departs from what is accepted as the ideal, is the extent to which consequences will and must follow.

I personally view the diet containing a large proportion of fresh raw fruits and veg- etables accompanied by 3 to 4 ozs. of concentrated protein as being the most satisfactory. The diet may have to be manipulated in various ways, in disease and during the process of recovery. What I am here discussing represents certain basic principles of dietetics which are generally applicable to the sound and healthy. The diet of the invalid may have to be modified considerably and frequently as their strength and weakness alternate, as the energy ebbs and flows, as the needs fluctuate from day to day. Considerable knowl- edge and skill is required in order to feed the sick adequately without imposing nutrition- al burdens which prove enervating and contribute to the misery of the sufferer. In acute disease it is relatively simple: abstain from food, i.e. fast. But in the case of the chronic sufferer, the problem is far more complex. Fasting may be employed, but there are limits to its practical nutritional reserves, and the extent of the toxemic load. Very few chronic sufferers are likely to recover during a fast. The fast merely provides a foundation for the reconstruction of health and in some cases it may require several fasts to provide this foundation, and the periods of feeding in between are most crucial. Progress may be inhibited if mistakes are frequent and serious. Correct feeding after the fast in recovery from chronic disease is an extremely critical and sensitive process requiring an accu- rate assessment of the nutritional needs and capacities of the invalid, and whilst there can be no mathematical accuracy applied to the provision of nutrients, it must always be kept clearly in mind that we do not nourish the organism by providing nutrients but by providing foods. The organism is constructed to ingest and digest foods and thereby assimilate nutrients. We do not secure health by feeding nutrients but by providing foods which contain nutrients. The difficulty is encountered in providing the right food in the proper proportion under the correct conditions, at a time when the organism is capable of using them.

Even if I say you can eat something does not make it either good or right. Some peo- ple try to persuade me to let them eat certain foods as though I am in some way respon- sible for physiological processes in relation to food. When I am asked these questions I often reply “What do you think?” Then they are forced to refer to their knowledge of Hygiene which usually compels them to accept the facts of reality.

People will argue that they are in some way special, the usual laws of life have to be “bent” a little in their case. These are all the subterfuges of compromise. There are only two types which are special, male and female. There are special periods such as infancy, pregnancy and lactation, but this does not mean that lettuce and apples are good at one time and fish and chips at another. Such periods require modifications of feeding but not of food. The exception is infancy when the infant secures his fruits, vegetables and nuts through his mother. He is eating them indirectly instead of directly.

== Article #3: Food Combining By Dr. Herbert M. Shelton ==

Instead of confining himself to the compounds or combinations that are turned out by nature, man turns out compounds and combinations of his own, a thing that no other an- imal in nature does. The animal makes a meal on whatever his instincts demand at the time and does not fill up on many kinds of food at a meal. The general rule, to which there may be an occasional exception (I have failed to find one), is for them to get but one food at a meal. Even the most simple things mixed together are not as good as they would be if taken separately. For it is only thus that we can eat as little or as much of a particular food as the body demands.

Instead of confining himself to the compounds or combinations that are turned out by nature, man turns out compounds and combinations of his own, a thing that no other animal in nature does. The animal makes a meal on whatever his instincts demand at the time and does not fill up on many kinds of food at a meal.

We are prone to follow custom and acquired habits in our eating practices and to ig- nore (commonly we do not know) the inhibiting effects of a variety of conditions and circumstances upon the process of digestion. Much of the alleged scientific defense of customary eating practices is but a lingering survival of ideas formed when little was known of the process of digestion.

It was long thought that the gastric juice was the only solvent of aliment. The office of the saliva was unknown and the other digestive juices with their several enzymes were unknown long after Beaumont discovered the work of the gastric juice. Thus it came to be held that the action of the gastric juice was the same on all articles of diet. It was thought that in some manner, not then understood, bile did aid in the digestion of fats and oils.

The British health reformer, Andrew Combe, accepted the view of Beaumont that saliva is lacking in alimentary solvent. (These solvents are today called enzymes). “The agent of chymification,” said Combe, “is the gastric juice.” It should be noted at this point that Graham took the opposite view. He held that saliva does contain a ferment or solvent. It is a strange thing that at this late date when the importance of the work of the salivary amylase, ptyalin, in the digestion of starch is well known, medical writers, in at- tempting to discredit Graham, list his differences with Beaumont as one of his mistakes. They are determined not only to discredit Graham, but also to discount the importance of salivary digestion. Recently I read the statement that “digestion begins when food has been swallowed.” Physiologists, physicians and gum-willies all seem to be determined to minimize the importance of salivary digestion. Even the importance of chewing of food in the mouth, which is a part of the digestive process, is negated.

In the effort to defend modern eating customs a number of imaginary activities are pictured as going on in the stomach. Beaumont showed long ago that the gastric juice quickly becomes intimately mixed and blended with the food in the stomach by the mo- tions of the stomach. These continuous motions are in two directions—transversely and longitudinally. It is now customary to deny that the gastric secretion is quickly mixed with the food ingested. This denial is necessary if food combining is to be discredited. Indeed, all enzymic limitations are ignored in the effort to combat the Hygienic heresy

In his Air, Food and Exercise, Rabagliati tells of witnessing the vomiting of a salad at 5 A.M. in about the same condition it was eaten at 7:30 the preceding evening. He men- tions that the salad “had rather too much vinegar on it.” Acids not only destroy ptyalin and thus stop starch digestion, but they also inhibit the secretion of gastric juice and re- tard protein digestion. It is the part of dietetic wisdom to avoid eating acid foods (vine- gar is not a food, but a poison), with protein. Because acids destroy ptyalin, it is well to avoid eating acid foods with starches.

An acid gastric juice is required to digest proteins. An alkaline medium is required for the work of ptyalin. For these reasons, protein foods and starch foods should not be eaten together. If a natural protein-starch combination, such as beans or cereals, is eaten, the body can so adapt its digestive juices to the digestive requirements of such a food that it is digested without too much trouble. If an artificial protein-starch combination is eaten, this adaptation cannot take place. Because of their complex character, beans, a protein-starch combination, tax the digestive powers more than simpler foods, but the gas, discomfort and other trouble that so commonly follow eating them, is not due so much to the beans themselves as to the company they keep. Baked beans are, of course, preferable to beans that are boiled and taken thoroughly saturated with water. If taken thus relatively dry, well chewed and eaten in proper combinations, beans will be found to be readily digestible.

A test meal of soup, beef-steak and potatoes remained in the stomach for three hours. The same meal with sugar remained for five hours. Sugar, like acids, has a marked in- hibiting effect upon the flow of gastric juice and upon gastric motility. The meal of soup, potatoes and steak was sufficiently difficult of digestion, but when the sugar was added, it became more so. In our regular eating habits we ignore, or do not know these simple facts. We tend to eat as those around us eat and we refuse to listen to the voice of those who seek to instruct us in the art of better eating. Perhaps this is the reason that it has been said that our people’s favorite dessert is baking soda. I think that Alkaseltzer has now supplanted baking soda as an after-meal tid-bit, largely due, no doubt, to the fact that few homes use soda any more, since little home baking is now done.

When we were children, our mothers would not permit us to eat sugar, candy or cookies before a meal. As she expressed it, “it spoils the appetite.” The fact is that no other food depresses the stomach and the desire for food as sugar does. The so-called “energy break” in mid-morning and mid-afternoon, when sugar or candy is taken to re- new lagging energies, is no different from taking a coffee-break for the same purpose. This practice of taking sugar has been dignified with the high-sounding title: “The Sci- entific Nibble,” but it is a fallacy. It is certainly a mistake to eat sugar, syrups, cakes, candies, pies, sweet fruits or honey with proteins.

Fat, like sugar and acid, also inhibits the secretion of gastric juice and the physical actions of the stomach. Too much fat taken with the meal results in acid eructations which leave a pungent, burning sensation in the throat. Fat inhibits gastric secretion. We have a great army of gastric invalids who overeat on butter and other fat, take sugar or acids with proteins and then are told by their physician that they do not have sufficient hydrochloric acid. The physician gives them hydrochloric acid to take and tells them that once this acid has been “lost” it cannot be regained. How does the physician know? Has he ever tried removing the cause of gastric hypo-secretion? Has he ever tried restoring the patient to health to see if his glands will function normally? Has he ever tried cor- recting the patient’s eating and living habits? The answer to all of these questions is the same. He has never made such attempts. He has been content to palliate the symptoms of his patient and leave causes untouched.

It is true, of course, that if they have taken the acid for a prolonged period, the practice itself has resulted in so much deterioration of the gastric glands that secrete hydrochloric acid, that the chances of full recovery are greatly reduced. The practice should never be started in the first place and only the grossest kind of ignorance or criminal indifference to a sick person’s welfare will ever prescribe such a treatment for the sick.

Fruits, because of their peculiar combinations, are best eaten at a fruit meal and not combined with starches, fats or proteins. As a rule they are abundant in either acids or sugars, hence do not combine well with other foods. As they undergo very little diges- tion in the mouth and stomach they should not be held up in the stomach awaiting the completion of gastric digestion of other foods.

There is no sharp line of division between the acid and subacid fruits. Neither is there a sharp line of demarkation between sub-acid fruits and sweet fruits. The gradations be- tween these classes of foods are almost imperceptible. The acid fruits are those with the most tart flavors—lemons, grapefruit, oranges, pineapple, sour apples, tomatoes, and similar fruits rich in acid. The sub-acid fruits are those that possess less acid flavors- pears, sweet apples, apricots, fresh figs, some grapes, sweet peaches, cherries and nec- tarines. The sweet fruits are those that are rich in sugar (sweet in taste)—persimmons, bananas, figs, dates, raisins, sweet grapes, mangoes and papayas. The avocado is a fat.

Tilden recommended eating the banana alone. He especially enjoined milk with this fruit, but said that it does not seem to go well with any other food. Although bananas do not give any special difficulty in digestion, if eaten with other sweet fruits, such as dates or sweet grapes, the same cannot be said for melons, which should be eaten alone. It is probably a great misfortune that we do not always feel the direct effects of imprudent eating immediately following a meal. For example, there are large numbers of people who have discomfort, even great discomfort following a meal in which melons are eat- en with other foods; but there are many others who do not. This latter group can see no connection between their life of imprudent eating and the breakdown of their health in years. Their apparent impunity prompts them to defy all the same rules of life.

At frequent intervals, some chemist or physician comes forward with the announcement that there is nothing to the idea that people have better health if they do not combine starch and protein foods in the same meal. They are sure to tell us that laboratory exper- iments show that digestion is carried out almost as quickly where these foods are com- bined as where only one is taken at a time. They are likely to add that experiments with certain patients verify this opinion of theirs.

We have in these announcements, two groups of men invading a field and posing as authorities therein, to which they are alien. Chemists know nothing of feeding man or animal. They should stick to chemistry. Physicians are not trained in dietetics. They know nothing of feeding the well and the sick. They are trained in the black art of poi- soning the sick. I will not say that they should stick to this practice, but I will say that they should cease trying to pass themselves off on the public as authorities in fields out- side their own.

Of what value are their laboratory experiments? Very little. A laboratory is not a hu- man being. It is not a human digestive tract. The laboratory experiment cannot be sub- stituted for the actual work of digesting a meal. Even feeding test meals and pumping out the stomach contents, or viewing the stomach through the X-ray is not a satisfactory approach to the solution of the problems involved in the heterogeneous and haphazard mixtures of foods commonly consumed at a meal.

Dr. Tilden once pointed out that nearly all such experiments are carried out by physi- cians and chemists who use the potato as the starchy part of the diet, and, he adds, “I have often stated, the potato is the least objectionable of any starch to be used with pro- tein, on account of its potash content.” My own view is that the potash content of the potato is not concerned in the matter at all. Potato starch digests in ten minutes under ideal conditions. I am of the opinion that it is the rapidity with which the potato starch digests that makes its combination with protein less objectionable than the combination of other starches with protein. It seems to be that the potato starch digests before the gastric juice of the stomach can accumulate in such quantity as to materially interfere with the digestion of the starch. Whatever the true explanation, the fact still remains that potato with protein, though objectionable, is less so than some other starchy foods with protein.

The man who has fed thousands of patients, old and young, and has had an oppor- tunity to study the effects of diets and food combinations upon the health and diseases of these people is in a far better position to judge the accuracy of the contention that protein-starch combinations are not conducive to good digestion and good health, than are the chemists who feed nobody and the physicians whose great work is that of poi- soning the sick.

Those of us who have made these observations know well that correct food combi- nations result in an immediate improvement in health by lightening the load the diges- tive organs have to carry. We know that we see better digestion and less fermentation and putrefaction. We see more comfort and less distress. There is less gas and little or no odor to the gas.

I do not believe that such experiences are worth anything if they cannot be explained by correct principles. Unless they can be explained by the facts of physiological chem- istry, particularly the chemistry of digestion, we may be only deluding ourselves. On the other hand, if our rules of food combining are soundly rooted in physiology, they are worthy of more than a passing notice.

It is frequently objected that nature, herself, combines starches and proteins and if nature does, we may do so also. This objection is not valid. It is based on the untenable assumption that everything in nature is designed or intended for food. The great rep- resentative examples of protein-starch combinations in nature are cereals and legumes. These are the very foods that are most prone to decompose in the digestive tract when eaten. Neither of them constitute the best of foods and neither of them is readily digest- ed. While a diet of cereals or a diet of legumes is inadequate in several ways, there is reason to believe that some of the inadequacies that result from such dietaries are results of the failure of digestion, a failure that is probably the result of the protein-starch com- bination.

Physiologically, the first steps in the digestion of starches and proteins take place in opposite media—starch requiring an alkaline medium, protein requiring an acid medium in which to digest. The enzyme ptyalin (salivary amylase) that initiates starch digestion is active in an alkaline medium only and is destroyed by a mild acid. On the other hand, pepsin, the enzyme that initiates protein digestion is active only in an acid medium. If starches and proteins are eaten together, the acid gastric juice destroys the ptyalin and puts an end to salivary digestion of starch. That the presence of the undigested starch in the stomach interferes with the digestion of protein is shown by the presence of undigest- ed protein in the stools. Physiologists have shown that undigested starch absorbs pepsin and this will surely interfere with digestion of protein.

There is a marked and important difference between eating a food that is a natural protein-starch combination and eating two foods, one a protein, the other starch.

When starches and proteins are eaten together, there is a fermentation and this results in fouling the whole digestive tract. Fermentation means irritation and poisoning. If starch is eaten without protein, the gastric (stomach) secretions will not be acid, or will be so weakly acid that they will not interfere with salivary digestion. In this case here will be no fermentation, except from other causes, such as overeating, hurried eating, other wrong combinations, eating when fatigued, worried, angry, fearful, grieved, etc., eating immediately before beginning work, eating when in pain, fever or when there is inflammation, etc. The causes of indigestion are legion.

When the artificial protein-starch combination is eaten, not only undigested starch, but undigested protein will be found in the stools. The presence of undigested starch and protein in the stools is of far greater importance in determining the digestibility or indi- gestibility of a food combination than is the emptying time of the stomach. “Research” workers have found that the protein-starch combination delays the digestion of protein four to six minutes. This would seem to be unimportant, and I believe it is unimportant. If this brief delay in protein digestion represented all there is to the matter, we could for- get the whole thing and continue to eat haphazardly. But starch digestion is important, also. Then there is the fact that the delay in emptying time of the stomach is no criterion of the completeness with which gastric digestion of protein has been done.

Physiologists resort to a number of “dodges” to escape the obvious implications of the facts of the physiology of digestion. A fine example of this is contained in Physiolo- gy by V.H. Mottram, professor of physiology at the University of London. He says that when the food in the stomach comes in contact with the gastric juice no salivary action is possible. He says: “Now gastric juice digests protein and saliva digests starch. Therefore it is obvious that for efficient digestion the meat (protein) part of a meal should come first and the starchy part second—just indeed as by instinct is usually the case. Meat pre- cedes pudding as being the most economical procedure.”

Why should it make any difference what order in which we consume the various foods at a meal? Mottram explains it in this way: “the distal end of the stomach is that in which the churning movement that mixes the food with gastric juice takes place ... But the food in the quiescent end is still under the influence of the saliva, while the food in the motile end comes into contact with the acid gastric juice and no salivary action is possible.”

This means that if you eat your protein first so that it will be down in the lower end of the stomach and consume your starch last so that it will be in the upper part of the stomach, the protein will be digested below while the starch is digested above.

This means that if you eat your protein first so that it will be down in the lower end of the stomach and consume your starch last so that it will be in the upper part of the stomach, the protein will be digested below while the starch is digested above.

Assuming that there is any absolute demarkation between the food in the different parts of the stomach, and this assumption would be false, it is still not true that people in general, either instinctively or otherwise, consume their proteins and starches in this manner. Perhaps in England it is customary to eat meat at the beginning of a meal and pudding at the end, just as we have a similar practice of taking a dessert at the end of a meal in this country; but it is likely to be the practice there as here of eating bread and meat together. When the average man and woman eats flesh or eggs, or cheese, he or she takes bread with the protein. In eating hamburgers, sandwiches, hot dogs and simi- lar dietetic abominations, it is certainly not the custom to consume the protein first and then, at the end of the “meal” eat the bun or other bread. The protein and starch are eaten together and are thoroughly mixed in the mouth in the process of chewing before they are swallowed.

For good digestion, let us eat our proteins and starches at separate meals.

The Hygienic rules of food combining are based on certain facts of the physiology of digestion that are well-known to the orthodox biologist and physiologist. Although these specialists in science never make any effort to make a practical application of their knowledge to the everyday task of living, the known limitations of the digestive en- zymes make it important that some consideration be given to these in our eating habits. What I have to say in the remainder of this article is based squarely upon the current teachings of standard physiologies, as I learned them in my studies of science prior to my graduation, but a few weeks ago, from the University.

The human digestive tract is divided into three cavities: the mouth, the stomach and the intestines. Each of these cavities possesses its own characteristic digestive juice or juices with which to do the digestive work of the particular cavity. Thus the work of digestion may be divided into three steps or stages, the work of each cavity preparing the food for the advanced work of the next. Although physiologists and biologists tend to think of salivary and gastric digestion as relatively unimportant, many facts, which I shall discuss in a future article, indicate that the efficiency and satisfactoriness of intesti- nal digestion depend upon the thoroughness with which salivary and gastric digestion have been carried out. With this thought in mind we shall begin our studies of the diges- tive processes.

Digestion is essentially a process whereby large molecules are broken down into smaller molecules by the process of enzymatic hydrolysis. Hydro (water) lysis (to loosen), means to loosen up by water, or to cleave large molecules into smaller ones by adding water. The organic catalysts (enzymes) are necessary to speed up hydrolysis. Without enzymes, very high temperatures and strong chemicals are necessary to produce hydrolysis, but these destroy food values. In the stomach hydrolysis occurs in compara- tively low temperatures and in a short while. The thesis is that it takes a year or more to hydrolyze foods without enzymes. Unfortunately the end-products are never really the same. Thus we see that enzymes are of primary importance in digestion.

Without chemical digestion, the animal organism would derive no benefit from foods. The food must be reduced to the size necessary to pass through the mucous mem- brane of the intestine and it must be changed into substances that can be assimilated and used by the organism, such as simple sugar, resulting from carbohydrate digestion; glyc- erol and fatty acids, derived from the fats of our diet; and amino acids, derived from pro- teins. Without good digestion we rob ourselves of many important elements and permit decomposition and putrefaction which cause various and sundry troubles.

Enzymes are organic catalysts composed of complex protein; hence, the requirement of amino acids for their synthesis. (A catalyst is a chemical agent that, when added to reacting chemicals, greatly speeds up their reaction and may be recovered practically un- changed at the end of the reaction.) The vitamin molecule is also said to form part of the enzyme molecule. There are extracellular enzymes (exoenzymes), such as the digestive enzymes, and glycogenase, found in the liver, is an example. Exoenzymes are secreted from the cells that produce them, and they perform their activities outside the cell. En- doenzymes do their work inside the cells that produce them.

Each enzyme is specific in its action; by this is meant that it acts upon one class of food only (fats, carbohydrates or proteins) and upon no other, or upon one class of prod- ucts of previous enzymic activity. Indeed, each one of the different sugars requires its own specific enzyme. They perform their work best at body temperature.

Each enzyme is capable of acting only in a medium of a certain pH. The pH of a sub- stance is the measure of its acidity or alkalinity. An alkaline substance is one in which the hydroxyl ions (OH) are in excess of the hydrogen ion (H). If the hydrogen ions are in excess, the substance is acid. If the hydroxyl and hydrogen ions exist in equal concen- trations, the substance is neutral. For convenience, the physiologist expresses the con-

centration of hydrogen ions with the chemical symbol pH. Measuring the relative con- centration of hydrogen and hydroxyl ions with the potentiometer, substances with a pH of seven are neutral, becoming increasingly acid as the pH falls from seven to one and increasingly alkaline as the pH rises from seven to fourteen.

Enzymes exist in an inactive form designated as proferment or zymogen, within the cells that produce them. Some may remain inactive until activated by activators (an in- organic activator) and kinases (organic activators). Others are converted into active en- zymes at the moment of secretion. There are also coenzymes, where the action of an enzyme is dependent upon the presence of another substance as in the case of the de- pendence of pancreatic lipase upon bile salts. It was formerly thought that bile has an antiputrefactive action, but it is now thought that the greater amount of putrefaction of proteins and carbohydrates in the absence of bile is due to the fact that fats are not digest- ed off the food, thus protecting them from the digestive juices. This allows the foods to undergo bacterial decomposition, the end-products of which are toxic. The above should indicate the importance of not eating fried foods and of not saturating your bread, pota- toes, and other starch with butter, margarine, oil or other fat.

Food, upon being received in the mouth, is subjected to communition and insaliva- tion and is thus reduced to a soft mass known as a bolus. The first enzyme with which the bolus comes in contact is ptyalin or salivary amylase. This enzyme begins starch diges- tion, changing the starches to dextrine and maltose, if given sufficient time to continue its action in the stomach. I shall speak more of this later. The bolus acquires a neutral or slightly alkaline reaction that is essential to the continued action of the salivary amylase. If the saliva is distinctly acid, it immediately stops salivary digestion and the first step in converting starch into usable sugars is arrested.

After food has been masticated and insalivated, the bolus is sent through the esoph- agus to the stomach where gastric juice is poured out in large quantities (an average of 1.5 to 2.5 liters a day). It is a thin, colorless fluid with a definite acid reaction (pH of 0.9 to 1.7), containing protein, mucin, inorganic salts, about five percent hydrochloric acid, and the enzymes pepsin and gastric lipase. If no protein is eaten, the juice is almost neutral in reaction.

Shortly after food enters the stomach, contractions begin in the middle region, pass- ing down to the lower end called the pyloris. These actions thoroughly macerate the food with the gastric juice, forming the thin liquid mass now called chyme. The fundus or up- per end of the stomach exerts pressure on the food in it so that it constantly pushes the food further into the more active or prepyloric and pyloric end of the stomach. In thin way, all the contents of the stomach become a liquid chyme and are thoroughly mixed together. There can be no separation in the stomach of one part of the meal from the other. A blender also has the churning action only at the bottom but shortly after the mo- tor is turned on all the contents are thoroughly and evenly mixed. The churning motion in the lower part of the stomach, the addition of an enormous amount of fluid, plus the constant pressure of the fundus, (which the blender lacks) upon the food is more than enough to ensure the thorough maceration of the food.

As previously stated, the enzymes of the stomach are pepsin, and gastric lipase. Pepsin, which initiates protein digestion, requires an acid medium in which to work. It is secreted as the zymogen pepsinogen and rendered active by the hydrochloric acid of the gastric juice. Pepsin is active only in the presence of hydrochloric acid and the hy- drochloric acid may be destroyed by alkali such as baking soda, etc. Pepsin hydrolyzes proteins through several stages into proteoses and peptones, which are inabsorbable and must undergo further hydrolysis in the intestine by other proteolytic (protein splitting) enzymes.

The stomach enzyme, gastric lipase, asserts its activity upon fats, breaking them up into fatty acids and glycerols, but the action of this enzyme is inhibited by an acid medi- um.

Physiologists believe that fats undergo little or no digestion in the stomach because of the acid gastric juice, but Hygienists have shown that, with proper combinations, fats

can be digested in the stomach. The very fact that a fat-splitting enzyme is contained in the gastric juice, indicates that it is there for a purpose and, if in a medium of the right pH, it will exercise its properties. Fats and proteins are a very bad combination since proteins require a very acid medium for digestion and this would inactivate gastric li- pase. Fats also inhibit gastric secretion, it is thought possibly by the production of a hor- mone called enterogastrone. But where fats are eaten with green vegetables, preferably raw, the inhibiting effect of fats on gastric secretion is counteracted and protein digestion proceeds quite normally.

Salivary digestion or the action of ptyalin or salivary amylase upon starches occurs while chewing and swallowing food and for a brief time after it gets into the stomach. This is not sufficient time to complete salivary digestion. Unless starch-protein combi- nations are avoided, salivary digestion of starch is not completed. We have learned that pepsin, that acts on proteins, needs an acid medium in which to work, and salivary amy- lase, that digests starches, needs an alkaline medium. Then, if protein foods, such as nuts, cheese, etc., are eaten with starches, such as potatoes or bread, the gastric secretion will be acid because of the presence of the protein food, and will speedily bring to a halt all starch digestion in the stomach. The starchy food will be left incompletely digested until it reaches the small intestine for further hydrolysis, providing it has not undergone fermentation and decomposition. It must be remembered that it is during this waiting period, because of the temperature of the stomach, that fermentation and decomposition are most likely to occur. The end-products of bacterial decomposition are always poiso- nous.

When a starch is eaten alone, that is without protein, as for example, a potato, a gas- tric secretion, the pH of which is practically neutral, is poured into the stomach, and sali- vary digestion will combine in the stomach uninhibited. Other acids besides hydrochlo- ric acid destroy salivary amylase. Free acids of fruits, such as those of oranges, grape- fruit, pineapples, tomatoes, lemons, limes, sour apples, sour grapes, sour berries, etc., and the acid of vinegar as well as drug acids, destroy salivary amylase. The eating of acid fruits and the taking of vinegar-containing dressings suspends salivary digestion. The drinking of orange or tomato juice with the starchy breakfast cereals that conven- tional eaters consume, is hazardous.

Salivary and gastric (stomach) digestion, if carried out properly, prepares the food for intestinal digestion, where enzymes of the succus entericus (the secretion of the in- testinal glands) and the pancreatic juice and the coenzymes of the bile take over. In the intestine, the end-products of hydrolysis are reached and the food is ready for absorp- tion, which also takes place in the intestine.

In the intestine, the end-products of hydrolysis are reached and the food is ready for absorption, which also takes place in the intestine.

Succus entericus, the intestinal secretion, contains four or five enzymes and has a marked alkaline reaction. The enzymes are as follows: enterokynase, which activates trypsin (the protein-splitting enzyme of the pancreatic juice); erepsin, which completes the work of pepsin and trypsin, hydrolyzing peptides to their constituent amino acids. The hydrolyzing enzymes of the succus entericus hydrolyze disaccharides, which are double sugars, into monosaccharides, which are simple sugars such as glucose and fruc- tose. Without the hydrolyzing enzymes, to convert disaccharides to monosaccharides, the disaccharides would be eliminated by the kidneys because as such they are non-us- able by the tissues.

Maltase acts upon maltose, and dextrine, which are products of the salivary digestion of starches. Two other hydrolyzing enzymes are sucrase, which hydrolyzes sucrose to glucose, and fructose, and lactase, the milk sugar enzyme. Sucrose is cane sugar, but it is also found in vegetables, the juices of many plants and some fruits. Most fruits contain the monosaccharides glucose and fructose. (If combined properly, fruits are the easiest of foods to digest, because their sugars are already in an assimilable form, needing no further hydrolysis. They need only to be absorbed and used.) Lactase acts upon milk sugar (lactose), hydrolyzing it to glucose and galactose.

Bile serves many important functions in the small intestine. It is an alkaline fluid, pH about 6.8 to 7.7, consisting of water, bile pigments, bile acids, bile salts, cholesterol, lecithin and neutral fats. Secretion of bile in the liver is continuous but it enters the duo- denum only when chyme is present. Bile may be considered a coenzyme of pancreatic lipase as pancreatic lipase combined with bile splits fats more rapidly than it does alone. Bile helps in the absorption of fatty acids by combining with them, making them more soluble, hence more easily absorbed. Bile is needed in facilitating absorption of many fat soluble vitamins, especially vitamins D, E and K. Bile has many other functions not concerned with digestion.

The pancreatic fluid enzymes are trypsis, pancreatic amylase and pancreatic lipase. Trypsin hydrolyzes proteins into proteoses, peptones and polypeptids and, given enough time, under favorable conditions, will continue its action until the necessary amino acids are reached. The more efficient and complete peptic digestion has been in the stomach, the more likely will trypsin and erepsin be able to complete the hydrolysis of proteins. Normally, proteins should be hydrolyzed into proteoses and peptones by gastric diges- tion. Under favorable conditions, proteins may be passed into the intestine without pep- tic digestion. Physiologists think that the enzyme trypsin of the pancreatic juice can initi- ate protein digestion and may reduce these proteins to proteoses and peptones, polypep- tids, dipeptids and, finally, amino acids. It is reasonable, however, to think that thorough peptic digestion of proteins before they are expelled from the stomach assures the com- pletion of their hydrolysis in the intestine, thus avoiding putrefaction.

The Hygienist does not agree with the thought of physiologists that salivary and gas- tric digestion are unimportant. The thoroughness with which enzymes do their work de- pends upon the amount of time they have in which to work. Obviously, therefore, thor- ough peptic digestion of protein will shorten the time required for the completion of pro- tein hydrolysis in the intestine.

The several enzymes of the pancreatic and intestinal juices that complete the di- gestion of proteins, carbohydrates and fats in the intestine, function only in an alkaline medium. The chyme from the stomach is acid, but bile from the liver and the pancreatic juice, both of which are alkaline, quickly provide an alkaline environment for the action of the enzymes in the intestine. We need not concern ourselves with combinations, as they relate to intestinal digestion, except to point out that the best preparation for in- testinal digestion is good salivary and gastric digestion. Food combining is, therefore, of greatest importance as it relates to salivary and gastric digestion.

Dr. Vetrano recommends using as little soaking water as possible, soaking one side at a time, so all water will be absorbed, thus avoiding losing flavor and nutrients. It is important that the water used for soaking be distilled water. If any water remains after soaking the fruit, you can drink the water.
