A new study suggests that daily consumption of peanuts may support brain health and memory in older adults, offering a potentially accessible dietary strategy against age-related cognitive decline. Researchers found that eating approximately two servings of unsalted, skin-roasted peanuts each day for 16 weeks improved insulin responsiveness in brain regions critical for memory, according to the findings. The research adds to growing evidence linking metabolic health to neurological function in aging populations.
The study focused on insulin signaling, a process that often deteriorates with age and has been associated with the development of Alzheimer's disease. Improved insulin responsiveness in memory-related brain areas could help maintain cognitive function as people grow older, the researchers reported. While the results are promising, the authors noted that further investigation is needed to confirm the findings and understand the underlying mechanisms. The research was conducted over a 16-week period and involved older adult participants.
