Nutraceutical: Walnuts
Indication: Memory

Research: This cross-sectional study evaluated whether antioxidant-rich foods from the Mediterranean diet were associated with better cognitive performance in a subsample (447) of elderly participants (aged 55-80 years) from the landmark Spanish PREDIMED(1) study—a dietary intervention trial in asymptomatic individuals with high cardiovascular risk. The researchers evaluated the intake of various foods and performed neuropsychological tests to assess cognitive function in relation to diet, and analyzed the urinary excretion of polyphenols as a biomarker of daily intake of antioxidants.
Results: The study reported regular consumption of walnuts, but not of other nuts, was associated with better working memory. The investigators believe that the high polyphenol (antioxidant) content found in walnuts may be one of the key elements in helping to preserve cognition and fight age-related cognitive decline. Coffee, virgin olive oil and wine were also associated with better cognitive scores.
