Dietary Reference Intake Quiz

Dietary Reference Intake (DRI) Values

• DRIs are a set of nutrient reference values for healthy people in the United States and Canada.
• DRIs are used to assess and plan dietary intake for individuals and groups.
• DRIs are established by the Food and Nutrition Board of the National Academies of Sciences, Engineering, and Medicine.

Estimated Average Requirement (EAR)

• EAR is the average daily nutrient intake level estimated to meet the requirement of half of healthy individuals in a particular life stage and gender group.
• It is the middle of the bell-shaped curve representing the nutrient requirement distribution in the population.
• Consuming the EAR for a long time will not lead to deficiency in individuals requiring less than the average amount.
• However, individuals requiring more than the average amount will become deficient over time.

Recommended Dietary Allowance (RDA)

• RDA is the recommended daily intake level sufficient to meet the needs of nearly all (97-98%) healthy individuals in a particular life stage and gender group.
• RDA is set two standard deviations above the EAR.
• It ensures adequate nutrient intake for the majority of the population.
• RDAs are set for essential nutrients like vitamins and minerals.

Estimated Energy Requirement (EER)

• EER is an individual's estimated calorie needs based on age, gender, height, weight, and physical activity.
• It is not calculated using the same method as RDA due to the risk of weight gain with excess calorie intake.

Adequate Intake (AI)

• AI is established for nutrients where there is insufficient scientific data to set an RDA.
• AI is determined by examining the average intake of healthy individuals who appear to be meeting their nutrient needs.

Tolerable Upper Intake Level (UL)

• UL is the maximum daily intake level of a nutrient that is unlikely to pose health risks for most individuals.
• Exceeding the UL on a regular basis can lead to toxicity.
• The UL is relevant for nutrients where excessive intake may lead to adverse effects.

Daily Value (DV)

• DV is a reference value used for food labeling.
• It applies to people from ages 4 and up and is based on a 2,000-calorie diet.
• DV values are often similar to or close to the RDA.
