How does food insecurity affect health across the lifespan? What policy and practice changes could improve access to nutritious food? Work by multiple IHPI researchers highlights links between limited food access and chronic conditions in children and adults, shows dietary patterns shaped by social and economic factors, and examines stigma faced by families seeking assistance. Studies also explore long-term food insecurity trends, the health impacts of government nutrition support programs such as SNAP and WIC, and how rising costs and economic disparities make it harder for millions of U.S. households to secure reliable, healthy food.
