1. What are the dietary reference intakes (DRI’s)? What are they for? There used to only be one

reference intake, the RDA, why are there so many now?

2. Define each of the following in everyday language:

A. Estimated Average Requirements (EAR)

*Why DON’T we use this one as the recommended amount people should eat daily?

B. Recommended Dietary Allowances (RDA)

*Why DO we use this one as the recommended amount people should eat daily?

D. Tolerable Upper Intake Levels (UL)

*Should we strive to reach the UL for a nutrient every day?6. Using Food Labels (use food label image below):

3. Select a packaged food and find the "Nutrition Facts" panel. Then answer the following questions A. How many Calories are there in 1 serving of this food?
B. Look at the "Total Fat" and the "Saturated Fat". Is the Saturated fat PART of the Total Fat?
C. What does the % Daily Value mean? For example, if it says that for every 1 serving of this food I get 2% Daily Value of Vitamin C. What does that mean?

## Apply It

1. You have been hired to write a two-page article for a weekly magazine about why nutrition is important to health. Using simple terms and a good supply of photographs, create your article. Be prepared to share your project with the class.
2. Record a food diary this week. At the end of the week, circle the foods that contain SoFAS. Next to each food, write a substitute food to replace it. Record a food diary next week. Be sure to eat the substitute foods you have selected to replace the foods that contained the SoFAS.
3. Search the Internet for sites that claim to give you nutritional advice. Check to see who sponsors the sites and if the site is trying to sell you a product or service. Compare the information found on the sites to those recommended in this text. What similarities do you notice? What differences do you notice?
