A study by Penn State and other institutions uncovered a critical link between food security, the Supplemental Nutrition Assistance Program (SNAP) participation, and cognitive health in older adults.
The study aimed to explore how lack of food security and the role of SNAP could impact brain aging in the elderly.
It involved analyzing data from the National Health and Aging Trends Study, covering the years 2012 to 2020. The sample consisted of 4,578 older adults in the U.S.
Participants were categorized based on their experiences with food security and their status regarding SNAP, dividing them into three groups: those receiving SNAP benefits, those eligible but not participating, and those ineligible for SNAP.
The findings were quite telling. Older adults who were food insecure experienced faster cognitive decline compared to those who were food secure. The rate of decline in the food-insecure group was so significant that it equated to aging an additional 3.8 years.
Interestingly, the cognitive decline rate in SNAP-eligible nonparticipants was even more pronounced, akin to being 4.5 years older in terms of brain aging.
These results highlight the crucial role of food security in maintaining cognitive health as people age. It underscores the potential of SNAP in protecting against accelerated cognitive decline among older adults.
The study suggests that around four years of accelerated brain aging can have a substantial impact on the elderly, emphasizing the need for food security and the beneficial effects of SNAP.
The Takeaway
The importance of ensuring food security for aging populations cannot be overstated, especially considering its connection to maintaining cognitive health.
This study calls attention to the need for government action to provide accessible and encouraged participation in programs like SNAP for older adults.

The study, led by Muzi Na and colleagues, was published in The Journal of Nutrition, offering valuable information on the intersection of nutrition, public assistance programs, and brain health in the elderly.
