Daily peanut intake sharpens memory and brain function in seniors
A recent US study has revealed that daily peanut consumption can boost brain function and memory in older adults. The 16-week trial, involving 31 participants aged 60 to 75, found significant improvements in cerebral blood flow and verbal memory performance.
Peanuts, rich in plant-based protein, arginine, unsaturated fats, and polyphenols, support vascular health and have antioxidant properties. The study found that eating 60 grams of peanuts daily increased cerebral blood flow by 3.6%, specifically to the frontal and temporal lobes, crucial for memory and cognition.
Moreover, verbal memory performance improved by 5.8% in participants who consumed peanuts daily. The peanut skin, which provides extra dietary fiber and natural antioxidants, may contribute to these benefits. The clinical study began in January 2023, focusing on the effects of regular consumption of salted raw peanuts on brain function and memory in older adults.
The findings suggest that incorporating unsalted roasted peanuts with their skins into daily diets could help prevent age-related memory decline. This simple dietary adjustment may improve brain function and memory in older adults, potentially reducing the risk of dementia associated with declining vascular function in the brain.
