Questions and Answers

What is the primary purpose of the Dietary Reference Intakes (DRIs)?

  • To establish legal limits for food additives.
  • To recommend specific meal plans for individuals with dietary restrictions.
  • To establish a single ideal intake for each nutrient.
  • To assess and plan dietary intake for healthy individuals and groups. (correct)

    • What does the Estimated Average Requirement (EAR) represent?

  • The recommended daily intake based on a 2,000 calorie diet.
  • The maximum amount of a nutrient that is safe for most individuals.
  • The daily intake level sufficient for most of the population.
  • The average daily intake level to meet the needs of half of healthy individuals. (correct)

    • If an individual consistently consumes the EAR for a particular nutrient, what is the potential outcome?

  • They have a high probability of experiencing toxicity.
  • Individuals requiring more than the average amount may become deficient over time. (correct)
  • They are guaranteed to avoid deficiency.
  • They will always meet the ideal intake for all nutrients.

    Study Notes

    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.
    • 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.
