Zeaxanthin Cognition Randomized Trial3 4 [5] [6] [7] [8] 9 10 Dietary patterns rich in antioxidants, unsaturated fats, and fiber have been associated with favorable effects on brain health and cognitive performance [].2Lee Grace J. (2026)Effects of one avocado a day for six months on cognitive performance in overweight adults: A randomized controlled trial
Zeaxanthin Cognition Randomized TrialPolyphenol-rich foods such as blueberries and cocoa have been shown to enhance cerebral blood flow and brain activation [] and are linked to improved cognitive performance and reduced cognitive decline in older adults [,,,].2Lee Grace J. (2026)Effects of one avocado a day for six months on cognitive performance in overweight adults: A randomized controlled trial
Zeaxanthin Cognition Randomized TrialNuts, rich in unsaturated fats, fiber and bioactive phytonutrients have been associated with better cognitive outcomes and slower rate of cognitive decline across longitudinal studies [,].2Lee Grace J. (2026)Effects of one avocado a day for six months on cognitive performance in overweight adults: A randomized controlled trial
Zeaxanthin Cognition Randomized Trial1 2 1 The global population is aging [], and the number of older adults diagnosed with neurodegenerative conditions such as Alzheimer’s disease (AD) continues to rise, along with other chronic diseases that adversely affect cognitive function [].2Lee Grace J. (2026)Effects of one avocado a day for six months on cognitive performance in overweight adults: A randomized controlled trial
Zeaxanthin Cognition Randomized TrialIn this context, the randomized controlled trial by Lee and colleagues provides timely and rigorous evidence examining whether daily consumption of one avocado, without any other nutritional or lifestyle modifications, influences cognitive performance over six months in adults with central obesity.4Bulló Mònica (2026)Avocado consumption and cognitive health: Refining expectations for single-food dietary interventions
Zeaxanthin Cognition Randomized TrialDespite this favorable nutritional profile, evidence from intervention studies specifically examining avocado consumption and cognition remains limited.4Bulló Mònica (2026)Avocado consumption and cognitive health: Refining expectations for single-food dietary interventions
Zeaxanthin Cognition Randomized TrialGiven that obesity is associated with metabolic dysfunction, systemic inflammation, and an increased risk of cognitive impairment, extending this line of research to individuals with central obesity is particularly relevant [].4Bulló Mònica (2026)Avocado consumption and cognitive health: Refining expectations for single-food dietary interventions
Zeaxanthin Cognition Randomized TrialDiet plays a central role in shaping trajectories of cognitive aging, with growing interest in identifying specific foods that may preserve brain health before the onset of clinical impairment.4Bulló Mònica (2026)Avocado consumption and cognitive health: Refining expectations for single-food dietary interventions
