# '''Discovery'''. Niacin deficiency disease, called pellagra, was written about hundreds of years ago. It was not until the 20th century, however, that this disease was related to a dietary deficiency. This took place when a researcher placed subjects on a diet identical to that which caused pellagra-type symptoms in certain groups of people in the South. When these symptoms occurred in the experimental subjects, the researcher concluded that pellagra is a deficiency disease. Soon after, other scientists found that niacin was the missing link.
