New Research Reveals SNAP Benefits Could Slow Cognitive Decline in Older Adults

Exploring the Link between SNAP Participation and Cognitive Health

A recent study presented at the Alzheimer's Association International Conference 2025, held in Toronto, revealed compelling evidence regarding the role of the Supplemental Nutrition Assistance Program (SNAP) in supporting cognitive health among older adults. Over a decade-long analysis, researchers found that those who participated in SNAP experienced a slower rate of cognitive decline compared to their peers who were eligible but did not engage with the program.

Findings of the Study

The study monitored a diverse group of participants aged 50 and older, focusing on 1,131 individuals enrolled in SNAP in 2010 and 1,216 eligible non-participants. Throughout the ten-year period, the cognitive performance of these individuals was evaluated biennially using comprehensive interviews. Participants saw an estimated 0.10% slower decline in cognitive function, translating to an additional two to three years of cognitive health—a significant benefit for maintaining independence in daily activities.

Dr. María C. Carrillo, Chief Science Officer at the Alzheimer's Association, emphasized the importance of food security in relation to brain health. "This research underlines the critical impact that adequate nutrition can have on cognitive function," she stated. "Everyday actions that ensure food security can significantly alter brain health outcomes, potentially lowering the risk of Alzheimer's disease and related dementias."

Implications for Policymaking

The findings bring to light the urgent need for effective public health policies to ensure equitable access to essential programs like SNAP. Despite the positive findings, researchers identified that not all demographic groups benefitted equally. For instance, older Hispanic and Black non-Hispanic participants did not experience the same degree of cognitive preservation as their White non-Hispanic counterparts. This highlights the pressing issue of racial and ethnic disparities in health outcomes associated with aging.

Researchers recommend that healthcare providers recognize the potential cognitive preservation benefits of SNAP and advocate for support for those facing food insecurity. Dr. Suhang Song, a lead author of the study, remarked, "Encouraging patients to access food assistance can be a key strategy in delaying cognitive decline."

The Bigger Picture

With the implications of this study reaching beyond mere statistics, it sparks vital conversation surrounding the integration of nutrition and health policy. It raises questions about the systematic barriers that prevent certain populations from harnessing the full benefits of such programs and underscores the importance of health equity. The study heralds a call to action for both policymakers and communities to collectively address these disparities and improve access to nutritional support.

As we move forward, further research is needed to delve deeper into how nutritional assistance programs like SNAP can not only enhance food security but also improve cognitive health across various racial and ethnic groups. This aligns with the Alzheimer’s Association’s mission to advance research and improve care and support for individuals with dementia.
