Part II To calculate the percentage of calories (kcal) derived from each of the energy nutrients when the total number of calories is known, divide the calories from each nutrient by the total number of calories, and multiply by 100. (3 x 5 points each = 15 points) Example: A person consumed 600 kcal from CHO, 360 kcal from Fat and 240 kcal from Pro. How many kcal did she consume? What percentage of the total kcal in her diet was derived from each of the three nutrients? 600 CHO kcal from CHO 600 = 50% CHO 360 Fat total kcal 1200 240 Pro 1200 Total kcal kcal from Fat 360 = 30% Fat total kcal 1200 kcal from Pro 240 = 20% Pro total kcal 1200
1. If you consumed 400 kcal from CHO, 630 kcal from fat and 540 kcal from protein, what percentage of the total kcal was derived from each of the three energy providing nutrients?
2. A bran muffin contains 12 kcal from protein, 45 kcal from fat and 17 kcal from CHO. How many total kcal does the muffin provide? What percentage of the kcal in the muffin comes from each of the three macronutrients? If you know the number of grams of each nutrient in a food item, multiply the grams times how many calories per gram that nutrient provides.
3. A cup of chocolate ice cream contains 34 g fat, 50g CHO and 12 g protein. How many kcal are in the 1 cup portion? What is the percentage of calories from each nutrient?
