The Partnerships for Better Health Act establishes a new federal grant program to help underserved communities tackle chronic diseases through coordinated partnerships between health clinics, food providers, and community organizations. The Department of Health and Human Services and Department of Agriculture will award grants of up to three years (renewable for two additional years) to eligible nonprofits and public entities that lead local coalitions serving populations with high rates of chronic disease, food insecurity, or limited health access. Grant funds can support integrated care coordination, nutrition education, "Food Is Medicine" programs that deliver medically appropriate foods to patients, and data tracking systems to measure health improvements. Grantees must serve people earning up to 200 percent of the poverty line, use evidence-based practices, and report annually on outcomes including changes in blood sugar, blood pressure, food security, and emergency room visits. The legislation authorizes $15 million annually from fiscal years 2027 through 2031 to fund these community health partnerships.
