The final guidance addresses serving sizes of foods, including single-serving foods and other foods that can reasonably be consumed at one eating occasion and require dual-column labeling. It finalizes a draft guidance issued in November 2018.The final guidance provides questions and answers on topics related to: （1） the definition of a single-serving container； （2） reference amounts customarily consumed, which are used by companies to determine serving sizes； （3） dual-column labeling, including formatting issues for products that have limited space for nutrition labeling； and （4） miscellaneous issues, such as requirements relating to the labeling of chewing gum and to multi-unit retail food packages.
