Joseph Goldberger believed that pellagra was caused by a nutritional deficiency, particularly a lack of niacin in the diet. He conducted studies showing that pellagra could be prevented and treated by adding foods rich in niacin, such as meat and milk, to the diet.
Joseph Goldberger, a physician in the U.S. government's Hygienic Laboratory, the predecessor of the National Institutes of Health, discovered the cause of pellagra and stepped on a number of medical toes when his research experiments showed that diet and not germs (the currently held medical theory) caused the disease.
The physician Dr. Gaspar Casal first described pellagra in the 18th century. However, the definitive link between diet and pellagra was made by Dr. Joseph Goldberger in the early 20th century.
Pellagra
Dr. Joseph Goldberger observed that pellagra was not contagious like infectious diseases, as it did not spread through direct contact. He also noted that certain dietary factors, such as a lack of niacin and a diet high in corn, played a role in the development of pellagra. Additionally, through experiments on prisoners, he demonstrated that a balanced diet could prevent and cure pellagra.
Pellagra can be cured by taking nicotinamide. The nicotinamide can be found in pill form and will reverse the condition of pellagra.

Pellagra is not an infectious disease. Pellagra is a nutritional deficiency disease.
Joseph Wolpe's proposed theory based on classical conditioning explain's the classical conditioning theory is linked with phobias.
Primary pellagra results when the diet is extremely deficient in niacin-rich foods.
Untreated pellagra will continue progressing over the course of several years, and is ultimately fatal.
