Pellagra and its prevention and control in major emergencies

This document is a review of pellagra. Pellagra results from a niacin and/or tryptophan deficient diet. Earliest recorded reports of pellagra were made almost 250 years ago. The condition quickly became associated with maize-based diets and was seen to spread throughout Europe following the introduction of maize as a staple crop from its original home in the New World.
