Pellagra
Pellagra is a vitamin deficiency disease caused by dietary lack of niacin and protein, especially the essential amino acid tryptophan. Symptoms of pellagra are red skin lesions, diarrhea, dermatitis, weakness, mental confusion, and eventually dementia. This disease can be common for persons who obtain most of their food energy from corn, as corn is a poor source of tryptophan. Therefore this disease can be common amongst people who live in rural South America where — during winter — they live on corn. Usually the symptoms show during spring, and disappear over summer, to return the next spring, after another long winter.
