| Walnut Cognition Randomized Trial | Background Subjective cognitive impairment (SCI), the earliest sign of cognitive decline, affects 1 in 9 Americans aged older than 45 years. | 2 | Zarich S (2025) | Effects of Walnuts on Postprandial Cognitive Function in Adults With Subjective Cognitive Impairment: Protocol for a Randomized Crossover Trial. |
| Walnut Cognition Randomized Trial | In the short term, cognitive function may be impacted by the consumption of a single meal, suggesting that the meal components, and not solely the metabolic dysregulation resulting from the condition of obesity, can impact cognition. | 2 | Zarich S (2025) | Effects of Walnuts on Postprandial Cognitive Function in Adults With Subjective Cognitive Impairment: Protocol for a Randomized Crossover Trial. |
| Walnut Cognition Randomized Trial | With the global population aging, the prevalence of impairment and neurocognitive disorders has increased substantially, intensifying public health concerns [,]. | 4 | Hardaway Chante (2026) | Brain Foods: A Narrative Review of Food Items and Their Impact on Cognition over the Life Course |
| Walnut Cognition Randomized Trial | Among these, nutrition has emerged as a central and potentially scalable factor, with converging evidence suggesting that dietary exposures meaningfully influence brain structure [], function [], and long-term cognitive trajectories []. | 4 | Hardaway Chante (2026) | Brain Foods: A Narrative Review of Food Items and Their Impact on Cognition over the Life Course |
| Walnut Cognition Randomized Trial | Consequently, diets rich in berries, nuts, whole grains, leafy green vegetables, and fatty fish have been frequently characterized as “brain-supportive” due to their bioactive profiles and associations with improved cognitive outcomes []. | 4 | Hardaway Chante (2026) | Brain Foods: A Narrative Review of Food Items and Their Impact on Cognition over the Life Course |
