Groceries or School Cafeterias: How Households Respond to School Nutrition Mandates.

This article examines how the Healthy, Hunger-Free Kids Act (HHFKA) nutrition mandates, implemented in U.S. public schools starting in 2012, affected household grocery food purchases. Using national NielsenIQ panel data, the study finds that households with school-aged children reduced their grocery food quantity by about 6%, primarily in items associated with children's breakfast and lunch, indicating substitution toward healthier school meals. The nutritional quality of grocery purchases declined slightly but was substantially outweighed by the improved healthiness of school meals. Households facing greater financial and time constraints, and those with less healthy pre-HHFKA grocery purchases, showed stronger shifts toward school meals, suggesting the policy particularly benefited children in more vulnerable households. These findings have implications for policymakers, food manufacturers, and retailers regarding the impact of nutrition standards on consumer behavior and market dynamics.
