FOLSOM, CA - As the California walnut industry aims to boost category interest and sales, new research was published that explores whether incorporating walnuts into breakfast may benefit cognitive performance. While findings are preliminary, retailers can capitalize on the growing consumer interest in brain health by positioning walnuts as a smart and simple addition to breakfast.

The study from the University of Reading examined how consuming 50g of walnuts (a generous handful) mixed into muesli and yogurt was associated with differences in cognitive test performance of 32 young healthy adults (78% female) compared to a calorie-matched breakfast without nuts.1

"This study helps strengthen the case for walnuts as brain food," said Professor Claire Williams, who led the research at the University's Centre for Integrative Neuroscience and Neurodynamics (CINN), in a recent press release. "A hearty handful of walnuts with breakfast could give young adults a mental edge when they need to perform at the top of their game."

The study, published in Food & Function, was conducted with a small group of adults aged 18-30, limiting its applicability to the general population. Participants completed various cognitive tests while their brain activity was monitored in the six hours following each breakfast. Researchers observed differences in reaction time and memory-related tasks following walnut consumption, though results varied across tests, and accuracy improvements were not consistently seen. The study does not establish a cause-and-effect relationship, and further research is needed to determine whether similar effects would be observed in broader populations, including older adults and those with cognitive impairments.

The researchers suggest that walnuts' mix of nutrients – including omega-3 alpha linolenic acid (ALA), protein, and plant compounds – may be beneficial for cognitive performance. Walnuts are the only nut to provide an excellent source of omega-3 ALA (2.5g/oz), which has been researched to support brain health, heart health and more.2 One ounce of walnuts offers 18 grams of total fat, 2.5 grams of monounsaturated fat and 13 grams of good polyunsaturated fat. Walnuts also provide 4 grams of plant-based protein along with a variety of other nutrients in just one handful.3

“This study adds to our growing body of evidence that walnuts may play a valuable role in supporting cognitive function," said Robert Verloop, CEO of the California Walnut Commission, in a recent press release. "As consumer interest in functional foods grows, the California walnut industry is focused on reaching new, younger, health-conscious consumers with versatile nutrition messages, creating new opportunities for retailers.”

With demand for functional foods on the rise, retailers have an opportunity to position walnuts as a smart option for brain health. Strategic merchandising – such as cross-merchandising walnuts with popular breakfast items including bananas, berries and yogurt, or creating targeted displays – can attract shoppers focused on cognitive performance.
