Niacin deficiency causes pellagraFood rich in niacin and/or tryptophan are liver Kidney meat, poultry, fish Legumes and groundnut. Milk is a poor Source of niacin but its proteins are rich in tryptophan which is converted in the body into niacin (about 60 mg of tryptophan is required to result in 1 mg of niacin). In many cereals, especially maize, niacin occurs in "bound" form unavailable to the consumer.While pellagra is historically a disease of the maize eating population it was reported in India in the Telangana area of Andhra Pradesh in some segments of the population eating another cereal that is jowar (Sorghum vulgare).
