Dietary Reference Intakes

Instruction: The Dietary Reference Intakes (DRI) are a collection of four nutrient values used for different purposes. Provide the definitions for the abbreviations in your own words. When or why would these values be used?

1.RDA

2.AI

3.EAR

4.UL

Find the DRI tables online and answer the following questions:

5.How much calcium would a 15-year-old girl need each day? ________

6.How much calcium would a 35-year-old man need?________

7.How much calcium would a 60-year-old woman need?________

8.Why do you think these individuals require different amounts of calcium? (Think about the body and bone health throughout the life cycle.)

The Dietary Reference Intakes also provide the percentage of carbohydrate, protein, and fat necessary for a balanced diet. These are called the AMDR or Acceptable Macronutrient Distribution Ranges. Fill in the numbers for the ranges.

9.Carbohydrate___________________

10.Fat___________________

11.Protein___________________

12.Molly is a 22-year-old female. How much iron and vitamin A are recommended for her? Look in the DRI tables.

13.Molly takes a thiamin supplement that provides 3 mg of thiamin per day. She also takes a vitamin C supplement that contains 5 grams of vitamin C per day. What do you think about this?

(Hint #1: Look up the UL values for these nutrients. Some nutrients do not have a UL value. It may be that sufficient research has not been completed to set a UL value. In that case, compare the supplement to the value listed in the main DRI table.)

(Hint #2: Be careful with the measuring units for vitamin C. She is taking 5 GRAMS. The UL for vitamin C is listed in milligrams.)
