On December 31, 2019, the U.S. Food and Drug Administration (FDA) issued two final guidance documents to assist industry with compliance with the agency’s updated Nutrition Facts labeling regulations. The first final guidance, entitled, “Guidance for Industry: Serving Sizes of Foods That Can Reasonably Be Consumed At One Eating Occasion, Reference Amounts Customarily Consumed, Serving Size-Related Issues, Dual-Column Labeling, and Miscellaneous Topics” is a questions-and-answers style document and a helpful resource to consult for determining the serving size, number of servings, and appropriate Nutrition Facts Panel (NFP) format for different types of food packages.
