Vitamin Check

Are you getting enough of the vitamins, minerals, and nutrients you need? Use these Recommended Daily Intakes guidelines to make sure.

August 15, 2008

Most Americans who eat a variety of foods get the right amount of essential vitamins and minerals. To check your daily values, use the below reference guide from the Food and Nutrition Board, Institute of Medicine.

Dietary Reference Intakes
The DRI of a particular nutrient refers to the following set of reference values.

• Estimated Average Requirement (EAR): the average daily nutrient intake level estimated to meet the requirements of half of the healthy individuals in a life stage and gender group―it is used to plan and assess dietary adequacies for population groups.

• Recommended Dietary Allowance (RDA): the average daily dietary nutrient intake level sufficient to meet the nutrient requirement of nearly all (97 to 98 percent) healthy individuals in a particular life stage and gender group―it is derived from the EAR.

• Adequate Intake (AI): the recommended average daily intake level based on observed or experimentally determined approximations or estimates of nutrient intake for a group (or groups) of apparently healthy people that are assumed to be adequate―it is used when an RDA cannot be determined.

• Tolerable Upper Intake Level (UL): the highest average daily nutrient intake level 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 may increase.

• Acceptable Macronutrient Distribution Range: a range of intakes of a particular energy source that is associated with a reduced risk of chronic disease while providing adequate intakes of essential nutrients―it is technically not a Dietary Reference Intake.
