![]() In children and pregnant and lactating women, the EER includes the needs associated with growth or milk production. An EER is the average dietary energy intake that is predicted to maintain energy balance in individuals of a defined age, sex, weight, height and level of physical activity.The absence of a UL for a nutrient could reflect a lack of evidence rather than a lack of adverse effects, and therefore does not necessarily mean that excessive intake poses no risk.The UL is based on an indicator of adverse effect that is toxicological in nature, meaning that the effect is directly caused by the nutrient and can be prevented by maintaining intake below the UL.As intake increases above the UL, the potential risk of adverse effects increases.The UL is not a recommended level of intake.The UL is the highest average daily nutrient intake level likely to pose no risk of adverse health effects to almost all individuals in a given life-stage and sex group.The AI for young infants is based on the estimated daily mean nutrient intake of healthy full-term infants who are exclusively breastfed.When an RDA isn't available for a nutrient, the AI can be used as the goal for usual intake by an individual.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 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’s sufficient to meet the nutrient requirement of nearly all (97 to 98 percent) 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. ![]() ![]()
