Pellagra in Modern Times

The recommended daily allowance, or RDA, of niacin for adults is approximately 18 milligrams daily. Pellagra in modern times is associated with food insecurity, poor nutrition and crises that interrupt food distribution.3‘Pellagra’ - American Osteopathic College of Dermatology (AOCD). It typically occurs in adults between the ages of 20 to 50. The United States began fortifying breads, cereals and other foods with vitamins, including niacin, in the 1940s. This practice almost eliminated primary pellagra across the country.6‘Niacin – Vitamin B3.’ The Nutrition Source, 6 July 2020,
