The servings on labels

Question

are they usually wrong.. because some times i will measure a box of cereal or something and there be a servng less or so.. or even more..

Answer 1

Well, usually the label will say ABOUT * servings. It's not exact. It's more or less the average of all the boxes of cereal they make. They might accidently pack a few more or less ounces in the box.

Answer 2

all serving portions are designed to be a universal guide for comparison on nutrition.
