Nutrient percentages worksheet
Please read the directions carefully:
- Using a food label, you would like to learn more about, fill in the blanks to complete the following exercises. Round answers to 1 decimal point.
- Please fill in this activity on this document and be sure to maintain its formatting. Please save it as a Word Document as “Last Name_First Name_Activity2.docx” and upload it to NYU Classes by the due date.
- Please save the food label you used as a readable photo format (ex. JPEG, PDF etc.) as “Last Name_First Name_Food Label” and upload it to NYU Classes by the due date.
- You can either (1) take a picture of the label with a phone/camera (2) find the label on the manufacture’s website or (3) scan a physical label.
- Make sure all pictures or scans are clear and readable.
Step A: Fill in the numbers from your label
|Grams of carbohydrate per serving:||g|
|Grams of protein per serving:||g|
|Grams of fat per serving:||g|
Step B: Calculate the total calories per serving.
|g carbohydrate per serving||´ 4 kcal/g =||carbohydrate calories|
|g protein per serving||´ 4 kcal/g =||protein calories|
|g fat per serving||´ 9 kcal/g =||fat calories|
Step C: Calculate the percentage of calories from each of the energy nutrients in a serving of the food. Use the numbers from Step B to fill in the blanks for the equations. Be sure to use the total calories/serving obtained from Step B for the denominator, as you may discover that it differs from the total calories states on the label. You can find examples of similar equations in Appendix C of the text.
|´ 100 =||% calories from carbohydrates|
|´ 100 =||% calories from protein|
|´ 100 =||% calories from fat|
*Note that the total percentages for carbs, protein and fat should equal approximately 100%
