''Effect of deficiency:'' Insufficient silicon in the body may result in baldness or the graying of hair. Skin irritations and rashes may develop easily. Hearing and vision may also be affected, and the teeth may decay.

Use in the Body: Copper is found in the liver, gallbladder, lungs and heart. It is es- sential primarily for the absorption and metabolism of iron.
==== Copper ====
''Use in the Body:'' Copper is found in the liver, gallbladder, lungs and heart. It is es- sential primarily for the absorption and metabolism of iron.
Effect of deficiency: A deficiency in copper results in the same effects as an iron de- ficiency, such as retarded hemoglobin production, general debility, limited growth, etc.
''Effect of deficiency:'' A deficiency in copper results in the same effects as an iron de- ficiency, such as retarded hemoglobin production, general debility, limited growth, etc.
Recommended Allowances: No official recommendations are made for copper al- lowances. Some sources have estimated about 2 milligrams per day. Very few cases of copper depletion have been observed in humans.

==== Iodine ====
''Use in the Body:'' Iodine is found mainly in the thyroid gland. It is essential for the formation of an organic iodine compound called thyroxine which regulates some of the metabolic functions. Iodine is required in the oxidation of fats and proteins and for cir- culatory functioning.
Recommended Allowances: Daily iodine needs are very small. The following are the Daily Dietary Allowances (revised 1974):
''Effect of deficiency:'' An iodine deficiency is partially responsible for goiter (the en- largement of the thyroid gland) and cretinism (a subnormal metabolism). A lack of io- dine also leads to sensitivity to toxic accumulations, low physical and mental activity and a susceptibility to nervous disorders.
''Recommended Allowances:'' Daily iodine needs are very small. The following are the Daily Dietary Allowances (revised 1974):

Use in the Body: Zinc is found in the brain, genital organs, thyroid, liver and kidneys. It is needed in the healing of wounds and in the transfer of carbon dioxide from the tissue to the lungs. Zinc is also required in the manufacture of insulin and in the regulation of blood sugar.

==== Other Minerals ====
The functions and daily allowances of the other minerals in the body have not yet been fully understood. All are important to the health of the human organism, however, and should not be disregarded.
