Question

A 250 kcal yogurt serving contains 8 g of fat and 10 g of protein. How many grams of carbohydrate must be present for the label to be accurate? Show your calculation.

Accepted Answer

Approximately 34.5 g of carbohydrate (because 250 − (8×9 + 10×4) = 138 kcal; 138 ÷ 4 = 34.5 g).

Answer

About 45 g, since labels usually overstate carbohydrate content by ~30% and you must adjust upward for absorption inefficiencies.

Answer

Zero grams are required because the remaining energy must come from unlisted alcohol content typically in yogurts.

Answer

Approximately 17.25 g, obtained by halving the computed carbs to correct for fiber subtraction commonly applied on labels.
