Basic Operations

PART 1: Complete the following table.

1. List all the food that you, a friend, or a relative consumed over a two day period on the table I below.

(You must list at least 6 items for each day)

2. Conduct an internet search using Google or any other search engine to fill-in the calories, fat, protein, carbohydrate, calcium (Ca), iron (Fe), vitamin A, and vitamin C on the table I below. (If the exact item is not found, use the information from a similar item)

Table I

Day	Food at Meals or Snacks	Calories	Fat (g)	Protein (g)	Carbs (g)	Vit A	Vit C	Calcium (Ca)	Iron (Fe)

3. Use the above table I to compute the daily consumption of calories, fat, protein, carbs, calcium (Ca), iron (Fe), and vitamin C for the two day. Fill-in the Day 1, Day 2 and two- Day Total columns on table II.

4. What fractional part of calories, fat, protein, carbs, calcium (Ca), iron (Fe), vitamin A, and vitamin C comes from the food consumed in Day 1. Simplify your answer to the lowest terms, whenever possible on the last column on table II.

Table II

5. What percent of the protein were consumed in Day 1?

6. What percent of the carbohydrates were consumed in Day 2?

7. If the number of grams of fat times 9 equals the total calories from fat, describe how you would determine the total number of calories came from fat over the two days.

8. If the number of grams of protein times 4 equals the total calories from protein, describe how you would determine the total number of calories came from protein over the two days.

9. If the number of grams of carbs times 4 equals the total calories from carbs, describe how you would determine the total number of calories came from carbs over the two days.

10. If the total calories you consume come from protein, fats and carbs, how would you determine the total calories you consumed over the two days?

11. How would you determine the percent of calories you consumed came from carbs?

B. Answer the following questions:

1. Why is it important that your food intake includes calcium (Ca), iron (Fe), vitamin A, vitamin C, and folic acid?

2. Use the Dietary Reference Intakes tables found on “ http://fnic.nal.usda.gov/dietary-guidance/dietary-reference-intakes/dri-tables ” to determine whether you, your friend or relatives dietary intake meet the Recommended Dietary Allowances (RDA) for your age group and sex? If not, in what areas is it lacking? What foods could be added to increase consumption and bring up to the RDA? (Note: A pdf file of Recommended Dietary Allowances will also be made available to you on Blackboard in the event that the above link is no longer working.)

3. What foods in your diet are the major contributors of

Calcium? _______________________

Iron? _______________________

Vitamin A? _______________________

Vitamin C? _______________________

4. If you were to complete a food chart and found that you failed to meet the RDA in several categories, would this mean that you were headed for nutritional disorders? Explain briefly.

5. There is much interest in low fat diets today. Put together one meal having a total calorie content of at least 700 calories that has no more than 10% of the calories from fat. You do not need to have all of the foods have less than 10% of their calories from fat, but the average should be 10% or less. Try to make this something you might actually consider eating.

HINT: Start with your day that has the lowest % of calories from fat and make substitutions or additions/deletions as needed. You may want to utilize a list of foods sorted by % calories from fat that is on the webpage.
