Answer:
In the product, the percentage of calories coming from proteins is about 31%.
Step-by-step explanation:
The Nutrition Facts label provides information about the nutritional value of a processed food, stating composition, quantity, caloric supply and percentage of daily requirements.
The caloric supply of proteins is 4 calories per gram (cal/gr). For a total of 24 grams of protein the amount of calories it provides is:
24 gr X 4 cal/gr = 96 calories.
For a total (100%) of 310 calories per portion, the percentage of calories provided by proteins is
310 cal ---------------- 100%
96 cal ---------------- X
X = (96 X 100) / 310
X = 9600 / 310
X = 30,97% ≈ 31%
In the food, the caloric contribution of proteins represents 31% of the total calories. The calculation is obtained from the data provided by the Nutrition Facts label in the image.
