SNAP Participation Linked to Slower Cognitive Decline in Older Adults

Multiple recent studies presented at the 2025 Alzheimer’s Association International Conference and conducted by the University of Georgia reveal that participation in the Supplemental Nutrition Assistance Program (SNAP) is linked to slower cognitive decline in older adults, effectively preserving two to three additional years of cognitive health. These findings, based on analyses of thousands of adults over a decade, suggest that SNAP may delay the onset of mild cognitive impairment and dementia by supporting better nutrition and reducing food insecurity. However, the cognitive benefits appear to be stronger among non-Hispanic white participants compared to Black and Hispanic participants, highlighting disparities in health outcomes. Experts emphasize that beyond medications and diagnostics, addressing social determinants like food security through programs like SNAP could be a low-cost strategy to support brain health in aging populations. Despite the promising evidence, questions remain regarding the exact mechanisms behind these benefits and concerns about the impact of federal SNAP funding cuts on vulnerable seniors. Advocates and officials stress the importance of maintaining and expanding access to nutrition assistance to protect seniors' mental and physical well-being.
