  1. What are DRIs?
    • • Standards to guide safe & adequate intakes of essential nutrients for healthy humans.
    • – Sick individuals have different needs.

    • The year 2001, 2002, 2004 revision values were designed to promote optimal function & health for healthy people.

    • Are specific for groups of people based on: life stage, gender, conditions of pregnancy & lactation.

    • Are adequate for moderately active people.
  2. How are DRIs established?
    • By scientific committee literature review.

    • Nutrients are given an Recommended Dietary Allowance(RDA), Adequate Intake (AI), or Estimated Average Requirement(EAR) value by life stage & gender.
  3. How are DRIs established?

    RDA:
    level to meet 97-98% of needs
  4. How are DRIs established?

    AI:
    average or mean intake level
  5. How are DRIs established?

    EAR:
    average daily nutrient intake level estimated to meet the requirement of half the
  6. Other DRI Components
    • • Tolerable upper intake levels (UL) for vitamins& minerals.
    • – Highest intake level likely to pose no risk of adverse health effects.

    • • Acceptable Macronutrient Distribution Ranges(AMDR) for energy producing nutrients &essential fatty acids.
    • – % Calorie range.

    • Estimated Energy Requirement (EER) for Calories.

    • DRI for physical activity.
  7. DRIs Exist For:
    • • Vitamins
    • • Minerals
    • • Water
  8. DRI for Protein
    • The adult DRI for protein is set at 0.8 grams/Kg.This level is for inactive persons.

    • See appendix for gram/Kg need for infants,children, and adolescents.

    • • Although not DRIs: Active persons need more than the DRI, approximately 1.2 - 1.6 grams/Kg.
    • Endurance athletes need more than the DRI,approximately 1.8-2.0 grams/Kg.
  9. DRI for Calories
    • • Is calculated from formulas (See Appendix).
    • • Is set as an EAR and is the called the estimated energy requirement (EER).
    • • The EER is based on age, gender, and physical activity.
    • • The formulas require height in meters and weight in kilograms.
  10. DRI for Carbohydrate,Fiber & Fat
    • Carbohydrate: At least 130 gm/day for adults

    • • Fiber: M 38 gm/d F 25 gm/d, [adults]
    •     • 1.4 gm/100 Calories consumed

    • FAT: not determined for adults

    • • Essential Fatty Acids:
    • • Linoleic Acid:M17  F12 [adults, gm/d ]
    • • Alpha-Linolenic Acid: M 1.6   F 1.1 [adults, gm/d ]
  11. DRI for Exercise
    • There is a DRI for exercise!

    • It is 60 minutes cumulative moderate exercise per day.

    • That means moving body parts and sweating while you are doing it.
  12. Na, K, Cl & Water
    • In 2004 the DRI was published for Water and the Electrolytes (Na, Cl, and K)

    • Sodium (Na): 1.5 gm if 19-50 years Sodium

    • Chloride (NaCl): 19-50 years 3.8 gm (3.8 gm NaCl – 1.5 gm Na = 2.3 gm/day of Cl)

    • Potassium (K): 4.7 gm/day if >18

    • Water: 2.7 L/day if F  3.7 L/day if M
  13. Tolerable Upper Intake Levels: ULs
    • For vitamins with DRIs

    • For minerals with DRIs

    • For arsenic, boron,nickel, silicon, vanadium
  14. DRIs Do Not Exist For:
    • • Cholesterol
    • • Sulfur (sulfate)
    • • Cobalt
    • • Non-essential, nutritional supplements
  15. DRIs are used
    to achieve nutritional balance and health in the population.

    • in nutrition assessment, meal planning, health care, research, food industry, national defense, food programs, public policy, etc.
