Start with serving size, then compare similar foods in the same amount. On a U.S. Nutrition Facts label, the calories and nutrient amounts usually describe one serving—not necessarily the whole package. Use % Daily Value (%DV) to see whether an individual nutrient is low or high, and compare the nutrients that matter to your own priorities.
What to look at first on a nutrition label
Serving size and servings per container
Check the serving size and servings per container at the top of the label before looking at calories or nutrients. Serving sizes reflect amounts people typically eat; they are not recommendations for how much to eat. The FDA puts it plainly: “The serving size is not a recommendation of how much to eat or drink.” FDA guidance on serving size
The listed calories and nutrients usually apply to one serving. If you eat two servings, multiply those figures by two. If the package includes a second column for the whole package, use it when you plan to eat the entire package.

After establishing how much food the figures represent, check calories and the nutrients relevant to your decision. The label includes information such as saturated fat, sodium, dietary fiber, total sugars, and added sugars. The FDA uses 2,000 calories a day as a guide for general nutrition advice, not as a personal calorie target; individual needs can be higher or lower. FDA overview of the Nutrition Facts label

How to compare two foods fairly
Use the same quantity for both products. If their serving sizes differ, a per-serving %DV comparison can mislead because each percentage describes a different amount of food. Compare equivalent amounts—such as the same number of grams or milliliters—or adjust the figures to the amount you would actually eat. Include servings per package in that decision.
- Choose a common amount. Use matching serving sizes where possible, or compare the same weight or volume.
- Read the figures for that amount. If needed, scale the calories and nutrient amounts proportionally from the label’s serving.
- Compare nutrients that fit your priorities. Look at nutrients you want more of or less of rather than treating one number as an overall score.
- Check the amount you will actually eat. A package’s per-serving figures may not describe your usual portion.
The FDA recommends matching serving sizes when using %DV to compare products. FDA guidance on %DV

How to use % Daily Value
%DV indicates how much a nutrient in one serving contributes to a general daily diet. As a quick guide for an individual nutrient, the FDA considers 5% DV or less low and 20% DV or more high. These thresholds are not a grade of the food as a whole. For example, a higher %DV may be useful for a nutrient you want more of, but not necessarily for one you are trying to limit.
The FDA’s general 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. Which comparisons matter most depends on your needs and preferences; no single nutrient establishes that a food is universally best. FDA guidance on using the label

How to read total sugars and added sugars
Total Sugars includes sugars naturally present in foods, such as milk and fruit, as well as sugars added during processing. Added Sugars is shown as part of Total Sugars; it is not an extra amount to add to the total. Compare the two lines to distinguish the total sugar amount from the portion identified as added.
The FDA’s Daily Value for added sugars is 50 grams per day, based on a 2,000-calorie diet. This is a general reference value, not an individualized recommendation. Total sugars and trans fat do not have a %DV on the label, so compare their gram amounts when relevant. FDA explanation of added sugars

A quick grocery-store comparison
- First, match the amount: compare equivalent weights, volumes, or serving sizes.
- Then, check the package context: note servings per container and whether you expect to eat one serving or more.
- Use %DV as a nutrient-level shortcut: 5% or less is low and 20% or more is high for that nutrient.
- Compare the nutrients that matter to you: for example, fiber or potassium, or sodium and added sugars.
- Read sugar lines correctly: added sugars are included in total sugars.
These instructions apply to U.S. Nutrition Facts labels. The FDA introduced updated label requirements in 2016, including added sugars and vitamin D and potassium information, along with more prominent serving-size and calorie information. Label formats and rules differ by country, so do not assume U.S. conventions apply elsewhere.
