How to read a Nutrition Facts label

A Nutrition Facts label packs a lot into a small box. Here is the fast way to read one, in the order that matters most.

1. Start with serving size

Every number on the label is for one serving, not the whole package. Check the serving size and the servings per container first. If you eat the whole bag and it holds two servings, double everything.

2. Calories

Calories tell you how much energy one serving provides. How many you need depends on your age, size and activity, and the label's general advice is based on a 2,000-calorie day.

3. Use % Daily Value as a shortcut

The % Daily Value (%DV) shows how much a serving contributes to a daily total. As a rule of thumb from the FDA, 5% DV or less is low and 20% DV or more is high. Use it to compare products fast.

4. Nutrients to look at

5. Finish with the ingredient list

Ingredients are listed from most to least by weight. This is where you spot added sugars, seed oils and additives that the numbers do not show.

Frequently asked questions

What does 20% Daily Value mean?

It means one serving provides about 20 percent of the recommended daily amount for that nutrient, based on a 2,000-calorie diet. That counts as high.

Why does the label show both Total Sugars and Added Sugars?

Total Sugars includes naturally occurring sugars, such as those in fruit and milk. Added Sugars shows only the sugars added during processing.

Are serving sizes the same as portions?

No. A serving size is a standard reference amount. Your portion may be larger or smaller.
