<br />
The '''Dietary Reference Intakes (DRIs)''' are a set of nutrition reference values developed by the Institute of Medicine (IOM) of the National Academies in the United States. These values are used to assess and plan dietary intake for healthy individuals and are based on research about the relationship between nutrient intake and the prevention of disease and promotion of health.<br />

DRIs are intended to serve as a guide for good nutrition and provide important information to health professionals and policy makers. They are used to develop nutrition programs, establish labeling on food, and for clinical dietary counseling.<br />
<br />
== Components of DRIs ==<br />
The DRIs encompass four key reference values, each serving a unique purpose in dietary planning and assessment:<br />
<br />
=== Estimated Average Requirement (EAR) ===<br />
<br />

<br />
; [[Estimated Average Requirement]]:<br />
: The EAR is the daily nutrient intake value estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. It is used to assess the nutrient adequacy of populations and to plan for the nutrient intake of groups.<br />
<br />
=== Recommended Dietary Allowance (RDA) ===<br />
; [[Recommended Dietary Allowance]]:<br />
: The RDA is the average daily dietary nutrient intake level sufficient to meet the nutrient requirements of nearly all (97 to 98 percent) healthy individuals in a particular life stage and gender group. It is often used as a goal for individual intake.<br />
<br />
=== Adequate Intake (AI) ===<br />
; [[Adequate Intake]]:<br />
: When sufficient scientific evidence is not available to calculate an EAR and subsequently the RDA, an AI is established. This is a recommended intake level based on observed or experimentally determined estimates of nutrient intake by a group of healthy people. The AI is assumed to be adequate for most individuals.<br />
<br />
=== Tolerable Upper Intake Level (UL) ===<br />
<br />
[[File:Dietary Reference Intakes.svg|thumb|right|Chart indicating the UL for various nutrients.]]<br />
<br />
; [[Tolerable Upper Intake Level]]:<br />
: The UL is the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects for almost all individuals in the general population. As intake increases above the UL, the potential risk of adverse effects increases.<br />
<br />
== Application of DRIs ==<br />
The DRIs are used by both health professionals and the public to help people eat a balanced diet that provides the nutrients they need for good health. Dietitians and nutritionists use the DRIs to:<br />
* Plan and assess the nutrient intakes of individuals and groups.<br />
* Develop and deliver nutrition education programs.<br />
* Design meals and menus for schools and other institutions.<br />
* Create dietary supplements and food products.<br />
<br />
== Updating the DRIs ==<br />
DRIs are periodically updated to reflect new scientific information about nutrient needs and the relationships between nutrient intake, health, and disease prevention. The IOM collaborates with Canadian health and research organizations to develop and update the DRIs.<br />
