The RDA, or "Recommended Daily Allowance," is the daily amount of nutrients sufficient to maintain health for 97 per cent of the population. Originally compiled in the 1940s by a committee established by the United States National Academy of Sciences, the RDA was replaced in 1997 by the DRI (Dietary Reference Intakes) by the Food and Nutrition Board of the Institute of Medicine. RDA is a general standard for population subgroups, and is not individually calculated. DRI is calculated based on an individual's height, weight and gender.
