  Dietary Reference Intake - Wikipedia, the free encyclopedia
Dietary Reference Intake is a set of guidelines set up in 1997 to give more detailed guidance than the RDA system which preceded it.
The DRIs are a set of four reference values: Estimated Average Requirements (EAR), Recommended Dietary Allowances (RDA), Adequate Intakes (AI), and Tolerable Upper Intake Levels, (UL) that have replaced the 1989 Recommended Dietary Allowances (RDAs).
The name RDA was dropped in favour of Dietary Reference Intakes (DRIs).

 Dietary Reference Intakes: Definitions
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 gender 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.
An EER is defined as the average dietary energy intake that is predicted to maintain energy balance in healthy, normal weight individuals of a defined age, gender, weight, height, and level of physical activity consistent with good health.

 Nat' Academies Press, Dietary Reference Intakes for Calcium, Phosphorus, Magnesium, Vitamin D, and Fluoride (1997)
DRI DIETARY REFERENCE INTAKES FOR Calcium, Phosphorus, Magnesium, Vitamin D, and Fluoride Physiology of Absorption, Metabolism, and Excretion In both children and adults, fractional intestinal magnesium absorption is inversely proportional to the amount of magnesium ingested (Kayne and Lee, 1993).
Total magnesium intake is usually dependent on caloric intake, which explains the higher intake levels seen in the young and in adult males and the lower levels seen in women and in the elderly.
Investigations are needed to assess the inter-relationships between dietary magnesium intakes, indicators of magnesium status, and possible health outcomes that may be affected by inadequate magnesium intakes, such as hypertension, hyperlipidemia, atherosclerotic vascular disease, altered bone turnover, and osteoporosis.

 Dietary Calcium Intakes of Urban Children at Risk of Lead Poisoning
Quintile means of calcium intake (± SE) were 222 ± 18; 491 ± 13; 710 ± 8; 890 ± 9; and 1,416 ± 65 mg/day for the 1-3-year-old children and 234 ± 21; 493 ± 14; 739 ± 9; 887 ± 10; and 1,367 ± 78 mg/day for the 4-8-year-old children.
Dietary calcium intakes of children in the lower and middle income groups were 725 ± 27, and 763 ± 65 mg/day, respectively, and blood lead concentrations were 10.6 ± 0.9 and 12.5 ± 1.3 µg/dL, respectively; these differences are not statistically significant (t-test, p > 0.05).
Mean calcium intakes of the 1-3-year-old (746 mg/day) and 4-8-year-old (739 mg/day) children in the current study are comparable to intakes of 750 mg/day for 1-2-year-old and 772 mg/day for 3-5-year-old children reported in a large nationwide survey (21).

The Recommended Dietary Allowance (RDA) is the dietary intake level that is sufficient to meet the nutrient requirements of nearly all individuals in the group.
The Tolerable Upper Intake Level (UL) is the maximum level of daily nutrient intake that is unlikely to pose risks of adverse health effects to almost all of the individuals in the group for whom it is designed.
It is recognized, however, that the low energy intakes reported in recent national surveys may mean that it would be unusual to see changes in food habits to the extent necessary to maintain intakes by all individuals at levels recommended in the report.
