A new study has found that eating walnuts for breakfast could enhance brain function throughout the day in young adults. Researchers at the University of Reading discovered that consuming a walnut-rich breakfast led to faster reaction times and improved memory performance compared to a calorie-matched breakfast without nuts.
The study, published in Food & Function, involved 32 healthy young adults aged 18–30. Participants consumed two different breakfasts on separate occasions—one containing 50 g of walnuts mixed with muesli and yogurt and another without nuts. Their cognitive performance and brain activity were then monitored over six hours after each meal.
Walnuts as Brain Food
Professor Claire Williams, who led the research, highlighted the significance of these findings, stating, “This study helps strengthen the case for walnuts as brain food. A handful of walnuts with breakfast could give young adults a mental edge when they need to perform at the top of their game.”
Brain activity monitoring revealed that walnuts may enhance cognitive efficiency during mentally demanding tasks. Additionally, blood samples taken from participants showed favorable changes in glucose and fatty acid levels—factors that could play a role in boosting brain function.
More Research Needed
The findings contribute to previous studies supporting the cognitive benefits of nut consumption, particularly walnuts. However, this research is the first to examine the immediate impact of walnuts on brain performance throughout a single day.
Scientists believe that the combination of omega-3 alpha-linolenic fatty acids, protein, and polyphenols in walnuts may be responsible for these cognitive benefits. Despite the promising results, the researchers emphasize the need for further studies to fully understand the mechanisms behind walnuts’ effects on brain function.
