The guidelines exist mostly to shape federally funded nutrition programs that provide food in one form or another to a huge swath of Americans: the 42 million people served by the Supplemental Nutrition Assistance Program (Snap or food stamps); 6.7 million moms and children in the Supplemental Nutrition Assistance Program for Women, Infants and Children (WIC); and 2.6 million seniors in the Meals on Wheels program. Federal monies also feed an unspecified number of mostly low-income, food-insecure or health-challenged Americans through Food Is Medicine programs. And, consequentially, they fund the school lunches that are served to almost 30 million kids every day.
