Understand Your Serving and Total Carbohydrate
A nutrition label describes a specific amount of food. Your portion may be smaller or larger, so start with the amount before comparing the numbers.

Serving is not a prescription
The label serving reflects how much people typically consume. It is not an instruction to eat that amount. Check both serving size and servings per container: a package that looks like one portion may contain several.
Scale to your portion
If you eat half the listed serving, use half its nutrient amounts. Two servings means twice the amounts. For recipes, use the stated standard serving; changing how much you cook is different from changing how much you eat.
Read total carbohydrate, not just sugar
Total carbohydrate includes starch, sugars and fiber. A food with little sugar can still supply carbohydrate. Use the total carbohydrate line and the portion when considering your own carbohydrate goals.
Total and added sugars are different
Total sugars include naturally occurring sugars and added sugars. Added sugars are listed separately on current U.S. labels. Do not subtract or guess an added-sugar value when a recipe only records total sugars.
A practical example
Hypothetical label example — not an actual product: one serving has 30 g total carbohydrate, 8 g total sugars and 3 g added sugars. Half a serving supplies 15 g carbohydrate, 4 g total sugars and 1.5 g added sugars. Eating two servings doubles every listed amount.
