timetable chart for vitamins and minerals daily intake

An AI is derived if there isn’t sufficient scientific evidence available to establish an EAR on which to base an RDA.The AI is expected to meet or exceed the needs of most individuals in a specific life-stage and sex group.The AI is the recommended average daily nutrient intake level based on observed or experimentally determined approximations or estimates of nutrient intake by a group (or groups) of apparently healthy people who are assumed to be maintaining an adequate nutritional state.

The RDA is the goal for usual intake for an individual.

The RDA is the average daily dietary intake level that is sufficient to meet the nutrient requirement of nearly all (97 to 98 percent) healthy individuals in a particular life-stage and sex group.

It is also used to assess the adequacy of nutrient intakes in a population, and can be used to plan the dietary intake of groups. The EAR is based on a specific criterion of adequacy, derived from a careful review of the literature.At this level of intake, the other half of the individuals in the specified group wouldn't have their needs met. It is the median daily intake value that is estimated to meet the requirement of half the healthy individuals in a life-stage and sex group. The EAR is an estimate of the median requirement for a nutrient.Equations to estimate energy requirementĭefinitions Estimated average requirement (EAR).

These tables provide dietary reference intakes for vitamins, elements (minerals) and macronutrients.
