Synopsis

Source of validity: Scientific
Rating (out of 5): 2

English Walnut (Juglans regia) has been studied for its potential neuroprotective effects, including possible benefits for Alzheimer’s disease. The scientific justification for its use is based on walnuts’ rich content of polyunsaturated fatty acids (notably alpha-linolenic acid), antioxidants (such as vitamin E and polyphenols), and anti-inflammatory compounds. Preclinical studies in animal models have shown that walnut supplementation may improve cognitive function, reduce oxidative stress, and decrease amyloid-beta aggregation, a hallmark of Alzheimer's pathology.

However, robust evidence in humans is limited. A few small clinical trials and observational studies suggest that higher walnut consumption may be associated with better cognitive function or slower cognitive decline in older adults, but these effects are not specific to Alzheimer’s disease and the quality of evidence is low. The mechanisms proposed include protection against neuronal damage, reduction in inflammation, and improvement in vascular health, all of which could theoretically benefit brain aging. Major health organizations do not currently endorse walnuts as a treatment for Alzheimer’s, but they are considered part of a healthy diet that may help reduce dementia risk. Overall, the scientific evidence supporting English Walnut for Alzheimer's disease is preliminary and insufficient for clinical recommendations.
