Label Reading Helper

A quick guide to reading Nutrition Facts labels for fat per serving.

Food labels can feel like a puzzle. The US FDA says 5% Daily Value or less of a nutrient per serving is low and 20% or more is high, and it stresses that serving size is not a recommendation of how much to eat. This helper walks through the parts of a label that matter most when you are choosing lighter foods.

How it works

  1. Check the serving size first, then compare it with what you will actually eat.
  2. Look at Total Fat per serving and its % Daily Value.
  3. Compare similar products side by side.
  4. Scan ingredients for sugar alcohols (sorbitol, mannitol, xylitol) if “sugar-free” foods upset you.

Hidden-fat watch

Compare two products?

Look at fat per serving AND serving size together. Same-sized boxes can hide very different per-serving fat. Two products at the same shelf height is the fastest comparison.

Educational only. Personal targets come from your clinician or registered dietitian. Serving size is what trips most people up.
It is the amount the label's numbers refer to. If the package has 4 servings and you eat the whole thing, multiply every number on the label by 4.
Total fat is the bigger picture for most people after gallbladder removal. Your clinician may also ask about saturated fat. Use your tracker to spot patterns, not to score foods as "good" or "bad."
% DV is based on a 2,000-calorie average diet. It's a rough guide — not a personal medical target. Ask your clinician for personal numbers.
Compare two similar products side-by-side on the same shelf. Look at fat per serving AND serving size. Same package size can hide very different per-serving fat.
