In nutrition labeling, what does "serving size" indicate?

• A. The calories in the entire package
• B. The total number of servings in the package
• C. The amount of food the manufacturer designates as one serving, used to calculate nutrient values.
• D. The recommended serving size according to dietary guidelines

Answer: (C)

Serving size is the amount the manufacturer designates as one serving, and it serves as the reference point for all nutrient values on the label. All calories, fats, carbohydrates, protein, vitamins, and minerals are listed per this amount, so you can see what you get in a standard portion. If you eat more or less than that amount, you adjust the numbers accordingly because the nutrients scale with portion size. The package may contain multiple servings, which is shown separately, but the label’s serving size itself is not the total amount in the package or a suggested portion from guidelines—it’s the defined unit used to calculate and compare nutrient content.
