Mathematica’s nutrition research uncovers evidence to help improve food and nutrition support for individuals, families, and communities.
From studying the effects of targeted taxes on consumption of sugar-sweetened beverages to examining the impact of providing employment and training services to participants in the Special Nutrition Assistance Program (SNAP), we partner with federal, state, and local decision makers on their journeys from inquiry to insight.
