Pellagra causes skin lesions that appear to be leprosy, sensitivity to light, aggression, insomnia, weakness, mental confusion, paralysis of limbs, diarrhea and eventually dementia.
Pellagra was common in the past when poverty led to malnutrition or where corn was a main staple and was prepared and stored in such a way that niacin was depleted from food.
Niacin supplementation prevents pellagra, a disease that occurs in people who rely heavily on corn as the main source of food and who do not eat much meat or milk.
Niacin deficiency results in pellagra, which involves skin rashes and scabs, diarrhea, and mental depression.
Extreme niacin deficiency results in a condition called pellagra, one of the negative side effects.
There and in Lombardy the disease known as pellagra is most widely diffused.
A bill for the better prevention of pellagra was introduced in the spring of 1902.
