Peanuts May Improve Brain Function in Older Adults
Daily peanut consumption linked to better memory and brain health in aging individuals.
The Brief
- Study shows daily peanuts improve insulin response in memory-related brain areas.
- Researchers observed increased cerebral blood flow and cognitive improvements.
- Peanuts contain nutrients that may support brain health and slow aging processes.
A study published in the journal Food & Function found that two daily servings of unsalted, roasted peanuts improved insulin responses in brain regions associated with memory.
Researchers had 31 healthy adults aged 60 to 75 consume peanuts in different ways over 16 weeks, and compared results to a control period without peanuts.
Insulin was administered through the nose, and brain blood flow was measured using arterial spin labeling magnetic resonance imaging (ASL-MRI).
Increased blood flow to the brain was associated with better cognitive function, as measured by the Cambridge Neuropsychological Test Automated Battery.
Another 2025 study found similar results, showing improved cerebral blood flow and verbal memory after four months of peanut consumption.
Peanuts contain unsaturated fats, dietary fiber, vitamins, minerals, and bioactive compounds that may contribute to brain benefits, according to senior study author Dr. Peter Joris.
