To compare packaged foods in the United States, first check how much food each Nutrition Facts panel represents, then compare equivalent amounts and use % Daily Value (%DV) to evaluate nutrients that matter to you. A serving size is a comparison baseline—not a recommendation for how much to eat—and %DV is a quick guide for individual nutrients, not an overall health score.
What should you look at first on a nutrition label?
Serving size and servings per container
Start at the top of the Nutrition Facts panel. The serving size tells you the amount used for the calorie and nutrient figures, and servings per container indicates how many such servings are in the package. FDA serving sizes reflect amounts people typically consume; they are not recommendations for how much to eat or drink. See the FDA guidance on serving size.

If you eat two servings, multiply the listed calories and nutrients by two. If the package provides a separate column for the whole package, you can use that column for the entire package instead. Think about the amount you realistically expect to eat, not just the printed serving.

Once you know the serving basis, check calories and the nutrients relevant to your priorities. The FDA uses 2,000 calories per day as a reference for general nutrition advice; an individual’s calorie needs may be higher or lower. Treat that figure as context for the label, not a personal target. The FDA explains the information shown on the Nutrition Facts label.

How do you compare two foods with different serving sizes?
Compare equivalent amounts. If one cereal lists nutrients for 30 grams and another for 40 grams, their per-serving numbers do not describe the same quantity. Use a common amount—such as the same number of grams or milliliters—and adjust the figures accordingly, or compare %DV only after confirming the serving sizes match. FDA advises matching serving sizes when comparing %DV across products.
For a practical comparison, note each product’s serving size and servings per package, then consider how much you would actually eat. A product with lower figures per serving may not be lower for the quantity you plan to consume.

How should you use % Daily Value?
%DV indicates how much a nutrient in one serving contributes to a general daily diet. FDA’s rule of thumb is that 5% DV or less is low and 20% DV or more is high for an individual nutrient. These are guides for reading one nutrient at a time—not a composite grade of a food.

The FDA’s guide to low and high %DV explains this approach.

Which nutrients are worth comparing?
For many comparisons, look at both nutrients to get more of and nutrients to limit. FDA examples of nutrients to get more of include dietary fiber, vitamin D, calcium, iron, and potassium. Examples to get less of include saturated fat, sodium, and added sugars. Compare the nutrients that fit your own needs and preferences; a single number cannot establish which food is universally best.
Total sugars and trans fat do not have a %DV on the label, so compare their gram amounts when relevant. Keep the serving basis consistent when looking at those amounts, too.

What is the difference between total sugars and added sugars?
Total Sugars includes sugars naturally present in foods, such as fruit and milk, as well as added sugars. Added Sugars reports sugars introduced during processing and certain sweeteners. The word “includes” means added sugars are part of the total-sugars amount; do not add the two lines together.

The FDA lists 50 grams per day as the Daily Value for added sugars, based on a 2,000-calorie diet. This is a general label reference, not an individualized allowance. Read the FDA explanation of added sugars for details.

A quick grocery-store comparison
- Find the serving basis: check serving size and servings per container on each package.
- Make the quantities comparable: match serving sizes or compare the same weight or volume.
- Check the amount you will eat: multiply per-serving figures for multiple servings, or use an entire-package column when available.
- Compare the relevant nutrients: use %DV as a low/high reference for nutrients such as sodium, saturated fat, fiber, or calcium; compare gram amounts for total sugars or trans fat when useful.
- Choose in context: weigh the nutrients you want more or less of alongside your preferences and realistic portion.
What the label can—and cannot—tell you
The Nutrition Facts panel helps you compare packaged foods using a consistent serving basis and declared nutrient amounts. It does not determine the best choice for every person, and its general 2,000-calorie reference should not be treated as an individual calorie requirement. These instructions describe U.S. FDA Nutrition Facts labels; labeling rules in other countries may differ. The FDA’s overview of how to understand and use the label provides additional context.
