The Supplemental Nutrition Assistance Program (SNAP) subsidized food purchases for 1 in 7 low-income Americans in 2015. Policy makers have long debated ways to control the types of foods that can be purchased with SNAP benefits to help people eat more nutritious foods. A randomized trial recently published in JAMA Internal Medicine shows that financial incentives and certain food restrictions lead people to eat more healthful diets and reduce their calorie intake, which could help prevent obesity and diseases linked to poor nutrition.
