How do you know what's safe to eat? Health and Human Services Secretary Robert F. Kennedy Jr. says most Americans don't. Kennedy points to a 67-year-old government exemption allowing ingredients that are generally recognized as safe, or GRAS, to be used in products without a full government safety review. Today, ultraprocessed foods make up about half of Americans' diets. Kennedy says the Food and Drug Administration doesn't know exactly how many ingredients are used in American foods, estimating it is between 4,000 and 10,000. #ultraprocessedfood #health #rfkjr
