Where is pellegra the desiese at?

Answer 1

Pellagra is primarily associated with regions where there is a heavy reliance on corn as a staple food, particularly in parts of Africa, Central and South America, and Southern Europe. The disease arises from a deficiency in niacin (vitamin B3) and is often seen in populations with limited access to diverse diets. Symptoms include dermatitis, diarrhea, and dementia, collectively known as the "three D's." Pellagra is less common in developed countries due to improved nutrition and food fortification practices.
