The Dietary Reference Intakes (DRIs) are nutrient reference values developed by the Institute of Medicine of The National Academies. They are intended to serve as a guide for good nutrition and provide the scientific basis for the development of food guidelines in both the United States and Canada. These nutrient reference values are specified on the basis of age, gender and lifestage and cover more than 40 nutrient substances.
In the mid-1990's, the DRIs replaced the Recommended Dietary Allowance (RDA) in the United States and the Recommended Nutrient Intake (RNI) in Canada. The DRIs are actually a set of several reference values that include values related to both adequate intakes and upper levels of intakes.
DRI Tables and Application
While the DRI values are established by different committees of experts, the values have been compiled into a single listing for easy viewing. A DRI summary guide has also been developed to help users of the DRIs understand the values and their applications. In addition, focused in-depth publications have been made available to help users understand the important considerations in applying the DRI values for assessing and planning diets.
