The Mediterranean, Dietary Approaches to Stop Hypertension (DASH) and Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) Diets Are Associated with Less Cognitive Decline and a Lower Risk of Alzheimer's Disease-A Review

This literature review evaluates the impact of the Mediterranean, DASH, and MIND diets on cognitive health, dementia, and Alzheimer’s disease (AD). Across 56 studies, higher adherence to these diets was generally associated with better cognitive function and reduced AD risk, especially for the MIND diet. The benefits stem from components like olive oil, green leafy vegetables, and berries, which are linked to improved brain function and reduced cognitive decline. The findings emphasize the role of dietary patterns in brain health, particularly in aging populations.

Incorporate elements of the MIND diet—such as leafy greens, berries, olive oil, and nuts—while minimizing processed and saturated fats. These changes may help slow cognitive decline. Since the evidence comes from observational studies and reviews, the findings suggest correlations rather than direct causation; thus, individual results may vary.
