What are the symptoms of niacin deficiency?
Niacin, or vitamin B3 occurs in most grains, especially whole grains. Severe deficiency of niacin (which is usually associated with malnutrition, or starvation) causes the disease pellagra. The main symptoms of untreated pellagra are the "4 D's": Diahrrea, dermatitis (red sores or itching), dementia and death. In previous generations, niacin was sometimes called Vitamin PP (for Prevents Pellagra.) The body can create niacin from tryptophan, an amino acid that occurs in milk and meat. People who eat little protein have an increased need for niacin. Many people believe that a mild niacin deficiency slows the metabolism and decreases tolerance to cold. The daily requirement for niacin ranges from 12mg in children to 18 mg in pregnant and nursing women. Niacin defiencies tend to occur only in areas where people eat corn (or maize) instead of wheat, rye or other grains. That's because corn contains niacin in a form the body cannot use. When corn meal or flour is processed with lime, it releases the niacin. One way to prevent a niacin deficiency is to take a daily multi-vitamin and eat a balanced diet including whole grains and poultry, milk, meat, and eggs.
