Recommended Dietary Allowance (RDA) — The RDA is the level of dietary intake that is sufficient to meet the daily nutrient requirements of 97 percent of the individuals in a specific life stage group. It is determined by the National Academy of Sciences based on the best available research data. Consumption of nutrients below the RDA does not necessarily constitute a deficiency because absolute nutrient requirements for individuals usually are not known with certainty. However, the further the intake is below the RDA, the more likely that a deficiency will develop. The average intake of most nutrients by children in the United States exceeds 100 percent of the RDA, with the exception of iron, calcium, and zinc. Ну и где Вы видите, что RDA - это обязательный минимум? |
