What is pollegra?

Answer 1

Pellagra is a nutritional deficiency disease caused by a lack of niacin (vitamin B3) in the diet, along with insufficient intake of tryptophan, an amino acid that the body can convert into niacin. It is characterized by the "three D's": dermatitis, diarrhea, and dementia. If left untreated, it can lead to severe health complications and even death. Pellagra is often associated with populations that rely heavily on corn as a staple food, which is low in niacin.
