Percent Composition of Diet: Homework Assignment

Using the data from the last assignment (five day Food Diary), do the following calculations and answer the questions. Record your answers within this Word document in BLUE font. You must show all of your work for questions 1-14 to get full credit . You must include units where applicable. When you finish, save as a Word document titled “HW 4 – last name, first name” and submit this through the appropriate link in Moodle. Do not email it . Failure to follow these instructions will result in a zero for the assignment.

 

1. Total ALL of the grams of carbs consumed during the five days.

 

2. Total ALL of the grams of lipids consumed during the five days.

 

3. Total ALL of the grams of protein consumed during the five days.

 

4. Total ALL of the grams of alcohol consumed during the five days.

 

5. Multiply the total number of grams of carbs consumed (from question 1) by 4 to calculate the number of kcal derived from carbs (remember…4 kcal per gram of carbohydrate).

 

6. Multiply the total number of grams of lipids consumed (from question 2) by 9 to calculate the number of kcal derived from lipids (remember…9 kcal per gram of lipid).

 

7. Multiply the total number of grams of protein consumed (from question 3) by 4 to calculate the number of kcal derived from proteins (remember…4 kcal per gram of protein).

 

8. Multiply the total number of grams of alcohol consumed (from question 4) by 7 to calculate the number of kcal derived from alcohol (remember…7 kcal per gram of alcohol).

 

9. Add all of the kcals together (from questions 5-8). What was the total kcal consumption over the five days?

 

10. Divide the kcal from carbs (from question 5) by the total kcal consumption (from question 9). What is the percent of kcal from carbohydrates consumed over the five days?

 

11. Divide the kcal from lipids (from question 6) by the total kcal consumption (from question 9). What is the percent of kcal from lipids consumed over the five days?

 

12. Divide the kcal from protein (from question 7) by the total kcal consumption (from question 9). What is the percent of kcal from proteins consumed over the five days?

 

13. Divide the kcal from alcohol (from question 8) by the total kcal consumption (from question 9). What is the percent of kcal from alcohol consumed over the five days?

 

14. Divide your total kcal consumption by 5. This gives you the average kcal consumption per day.

 

Answer the following additional questions IN DETAIL.

 

15. How does the percent carbohydrate consumption (from question 10) compare to what is recommended (AMDR)? What specific dietary changes could be made to improve this?

 

16. How does the percent lipid consumption (from question 11) compare to what is recommended (AMDR)? What specific dietary changes could be made to improve this?

 

17. How does the percent protein consumption (from question 12) compare to what is recommended (AMDR)? What specific dietary changes could be made to improve this?

 

18. Go to the following link to calculate EER (Estimated Energy Requirement): https://www.nal.usda.gov/fnic/dri-calculator/

Enter the information where indicated (sex, age, pregnancy/lactation status, height, weight, activity level) for yourself (or the person you interviewed to collect Food Diary data). To help select the most accurate activity level, please click on the “i” next to “Activity Level” to view the parameters for each level. Then, click submit. What is the EER (reported as “Estimated Daily Caloric Needs”)? How does the average daily kcal consumption (from number 14) compare with the EER?
