Look at the ingredient list before the nutrition facts. If the list is short and you recognize the names, it is probably a good choice.

The nutrition facts tell you how much. The ingredient list tells you what. They tell two different stories.

Front-of-package claims such as “source of protein,” “light,” and “natural” are regulated marketing, but they do more to sell than to inform.

What the science says

  • In observational studies, ultra-processed foods are associated with greater cardiometabolic risk.
  • The serving size declared by the manufacturer is often smaller than the amount actually consumed.

How to apply it

  • Compare products per 100 g or ml, not per serving.
  • Read the first 3 ingredients because they make up most of the product.
  • Watch for added sugars hidden under other names.
