DRIs are the stuff you find on food labels. But what do they mean?
DRI stands for Dietary Reference Intakes. It’s used for planning diets and making sure enough nutrients are taken in the daily food.
EAR means Estimated Average Requirements and is the amount of nutrients estimated to meet the needs of 50% of the people in a life-stage and gender group.
RDA means Recommended Dietary Allowance and is the nutrient intake level sufficient to meet the requirements of 97-98% of people. The RDA is calculated from the EAR and two standard deviations above and below the EAR.
AI stands for Adequate Intake and is based on the nutritional intake of a group fo healthy people. AI is used when there is not enough data to figure out EAR or RDA.
UL is the Tolerable Upper Intake Level is the level of micronutrients such as vitamins, that should not be exceeded to prevent toxification.
