How to Read U.S. Nutrition Facts Labels Without Getting Lost in Marketing Claims

Packaged foods often lead with bold phrases such as “high fibre,” “natural,” or “low fat.” These claims can be useful starting points, but they do not tell the full story. For products sold in the United States, the Nutrition Facts label offers a standard way to compare what is actually in a serving.

Serving size is the basis for every number on the label. It is not a recommendation for how much you should eat; it reflects an amount people typically consume. Check the number of servings in the package too. If you eat two servings, you are getting twice the calories and nutrients listed for one serving.

The % Daily Value, or %DV, shows how much a nutrient in one serving contributes to a daily diet. On the U.S. Nutrition Facts label, 5% DV or less is considered low and 20% DV or more is considered high. This is a U.S.-specific guide, so it should not be assumed to apply to food labels in other countries.

Depending on your needs, the label can help compare foods for fibre, vitamin D, calcium, iron, and potassium. When choosing between similar products, a higher %DV for fibre can be one useful signal, alongside ingredients, cost, taste, and how the food fits into the rest of your meal.

The same label can help you compare saturated fat, sodium, and added sugars. The distinction between total sugars and added sugars is especially useful: total sugars include naturally occurring sugars in foods such as fruit or milk, while added sugars are included during processing.

Ingredients are listed by weight, from the largest amount to the smallest. This can help you check whether a front-of-package claim matches the food itself. For example, if a bread is marketed as whole wheat, whole-wheat flour should appear near the beginning of the ingredient list.

Food labels are tools, not moral scorecards. They can help you make clearer comparisons, while leaving room for your preferences, budget, and the wider pattern of what you eat.
