MIND Diet Linked to Reduced Risk of Alzheimer's Across All Ages

Recent research from the University of Hawaiʻi Cancer Center highlights the potential benefits of the MIND diet in lowering the risk of Alzheimer's disease and related dementias, regardless of age. The study analyzed data from nearly 93,000 adults in the U.S. and found that individuals who adhered to the MIND diet, which combines aspects of the Mediterranean and DASH diets, were significantly less likely to develop neurodegenerative conditions.

The MIND diet emphasizes consumption of brain-healthy foods such as leafy greens, berries, nuts, and olive oil, all of which are rich in nutrients beneficial for cognitive health. Importantly, the study showed that even later in life, improving adherence to this dietary pattern can produce substantial protective effects. Participants who enhanced their compliance over a period of ten years experienced about a 25% reduction in dementia risk compared to those whose diet quality declined.

The research also revealed variations in the protective effects among different racial and ethnic groups. While African American, Latino, and white populations saw more pronounced benefits, the association was less evident among Asian Americans and Native Hawaiians. Researchers suggest that cultural dietary habits and existing genetic factors may influence these differences.

The findings, shared during Alzheimer’s and Brain Awareness Month and presented at the Nutrition 2025 conference, reinforce the importance of dietary choices in cognitive health. Lead researcher Song-Yi Park emphasized that it’s never too late to adopt healthier eating habits, and emphasizing plant-based, nutrient-rich foods can be an effective strategy to prevent or delay the onset of dementia—even in advanced age.

This study demonstrates the powerful role of large-scale research in informing public health strategies and underscores the potential of dietary interventions in combating neurodegenerative diseases.
