Dietary Guides and Standards

Dietary Reference Intakes (DRIs) are scientifically based nutrient reference values essential for a healthy population. They vary by gender and age and include four key values: Estimated Average Requirement (EAR), Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL). While DRIs offer detailed nutrient guidelines, Canada’s Food Guide for Healthy Eating simplifies dietary recommendations into easy-to-follow servings adjusted for age. Both resources aid individuals in maintaining optimal health through proper nutrition.

  1. Dietary Guides and Standards

  2. Dietary Reference Intakes (DRIs) • A set of scientifically based nutrient reference values for a healthy population • Values are based on gender and age • An umbrella term for four types of reference values: 1) Estimated Average Requirement (EAR) • The amount of a nutrient that supports a specific function in the body of half the population

  3. 2) Recommended Dietary Allowance (RDA) • 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 • Calculated based on the EAR, an RDA can only be set for a particular nutrient if there is sufficient scientific evidence to establish an EAR for that nutrient

  5. 3) Adequate Intake (AI) • If sufficient scientific evidence is not available to establish an EAR and set an RDA, an AI is derived for the nutrient instead

  6. 4) Tolerable Upper Intake Level (UL) • Highest level of continuing daily intake that is likely to pose no risk of adverse health effects in almost all individuals in the life-stage group

  7. Canada’s Food Guide for Healthy Eating • Recommendations are food servings not scientific values • Recommended servings based on age and age • Easier to access and follow than DRIs for most of the population
