U.S., Feb. 20 -- ClinicalTrials.gov registry received information related to the study (NCT07422220) titled 'Long-Term Effects of Walnut Consumption on Brain Function' on Oct. 02, 2025.
Brief Summary: Rationale: Healthy foods, including mixed nuts, may improve brain function, which is essential for cognitive and metabolic health, and may contribute to improved food intake regulation. It is therefore important to investigate the specific effects of walnuts on cerebral blood flow responses before and after intranasal insulin administration, as well as their associated functional benefits. The investigators hypothesize that long-term walnut consumption improves vascular function and insulin-sensitivity in the brain, thereby enhancing cognitiv...
