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.

 

	carbohydrate calories
		´ 100 =		% calories from carbohydrates
	total calories/serving

 

 

 

	protein calories
		´ 100 =		% calories from protein
	total calories/serving

 

 

 

	fat calories
		´ 100 =		% calories from fat
	total calories/serving

 

*Note that the total percentages for carbs, protein and fat should equal approximately 100%
