Healthy SNAP Act of 2025This bill amends the Supplemental Nutrition Assistance Program (SNAP) to redefine the foods eligible for purchase with SNAP benefits.Under the bill, SNAP benefits may not be used for soft drinks, candy, ice cream, or prepared desserts, such as cakes, pies, cookies, or similar products.Further, the Department of Agriculture (USDA) must designate by regulation foods and food products to include in the SNAP definition of the term food. USDA must consider food and products that (1) based on nutrition research, contain nutrients lacking in the diets of people in the United States; and (2) promote the health of the population served by SNAP, based on relevant nutrition science, public health concerns, and cultural eating patterns. USDA must also, to the maximum extent practicable, ensure that the fat, sugar, and salt content of the food and food products are appropriate. At least every five years, USDA must review and amend the list.In addition, prepared meals purchased with SNAP benefits must have nutritional values consistent with standards developed by USDA for the list of food and food products.A state agency may substitute different foods for food USDA designated under this bill, with USDA approval, so long as the foods are nutritionally equivalent; this is permitted to allow for different cultural eating patterns.
