A recent study from the NUTRIM Institutes at Maastricht University Medical Center in the Netherlands found that daily consumption of peanuts can improve cerebral blood flow in older adults. Researchers studied 31 healthy participants aged 60 to 75 who consumed 60 grams of unsalted, roasted peanuts daily for 16 weeks. In another phase of the study, participants avoided peanut consumption completely.
The results showed that cerebral blood flow increased by 3.6%, particularly in the frontal and temporal lobes, which are important for higher cognitive functions. This improvement in blood flow could be due to the nutrients found in peanuts, such as unsaturated fats, vegetable protein and polyphenols, which support vascular function.
In addition to the physiological benefits, participants also improved on verbal memory tests by about 5.8%. These results suggest that regular consumption of peanuts can not only promote blood flow to the brain, but also cognitive performance. However, other cognitive areas such as executive function and reaction speed did not show significant improvements.
However, the study has some limitations, including the small number of participants and the fact that all subjects were healthy. This makes it difficult to generalize the results to larger or health-compromised populations. Still, the findings provide valuable insight into how simple dietary changes can support brain health as we age.
