Question

Quizplus · Accepted Answer

To determine the number of kcalories in the given food, we need to calculate the contribution of each macronutrient.

Carbohydrates provide 4 kcal/g, so 25 g of carbohydrates provide 100 kcal (25 g x 4 kcal/g).

Proteins also provide 4 kcal/g, so 6 g of protein provide 24 kcal (6 g x 4 kcal/g).

Fats provide 9 kcal/g, so 5 g of fat provide 45 kcal (5 g x 9 kcal/g).

To calculate the total kcalories, we simply add the contributions of each macronutrient:

100 kcal + 24 kcal + 45 kcal = 169 kcal

Therefore, the best choice is B) 169 kcal.
