The RDA (recommended daily amount) and the IA (adequate intake) are the amounts of a vitamin or mineral that are needed to stay healthy and well nourished. As a result, you may need to consume more or less of a certain food, drink, or dietary supplement to meet the recommended values or recommended amounts. Recommended nutrient intakes vary by age and gender and are known as recommended dietary amounts (RDA) and adequate intakes (IA). Roberts, Stiebeling and Mitchell analyzed all available data, created a provisional set of energy quantities and eight nutrients and presented them to experts for review (Nestlé, 3).
Australia and New Zealand call the collective set of information nutrient reference values, with recommended dietary intake (RDI) instead of RDA, but EAR, IA and UL are defined in the same way as in the United States and Canada, although the numerical values may differ. The DRI calculator for health professionals is an interactive tool for calculating daily nutritional recommendations for diet planning based on dietary reference intakes (DRI) established by the Food and Nutrition Board of the National Academies of Sciences, Engineering and Medicine.
