Dietary Reference Intakes
The Recommended Daily Allowances, known as RDAs, arerecommendations for nutrients. They were developed by the Food andNutrition Board of the National Academy of Sciences/National ResearchCouncil. They are updated as new research findings surface.The RDAs state the amount of a nutrient that is needed for most people tostay healthy. They are different for children, adults, males, and females.
The Dietary Reference Intakes, known as DRIs, are an umbrellagroup that includes the following other nutrient measures:
DRIs are slowly becoming the more accepted form fornutrient recommendations. Experts expect that DRIs will take theplace of the RDAs in time.
