Embracing the MIND Diet Could Potentially Decrease Dementia Risk Across All Age Groups
It's All in Your Plate: Brain-Saving Diet Reduces Dementia Risk
As populations age and the number of dementia cases rise, a new study suggests that your dinner plate may hold the secret to preventing Alzheimer's disease. This latest research reveals that people who followed a dietary pattern known as the MIND diet were significantly less likely to develop Alzheimer's and related forms of dementia.
The MIND diet, originating from the fusion of the Mediterranean and DASH (Dietary Approaches to Stop Hypertension) diets, highlights the importance of brain-friendly foods such as leafy greens, berries, nuts, and olive oil. By adhering to this dietary pattern, individuals may substantially lower their risk of dementia.
The MIND diet has proven connections with lower dementia risk across various racial and ethnic groups, with notable benefits for Latino, white, and African American populations. While the connection isn't as pronounced among Asian American and Native Hawaiian groups, the study still encourages adopting a brain-healthy diet since it can still contribute to cognitive aging.
Particularly noteworthy is the impact of improvment in diet over time. Those who enhanced their adherence to the diet experienced up to a 25% lower risk of dementia, regardless of age. These helpful effects were observed similarly in younger and older age groups, demonstrating that it's never too late to adopt a healthy diet to prevent dementia.
"Our study findings confirm that healthy dietary patterns in mid to late life and their improvement over time can prevent Alzheimer's and related dementias," said Song-Yi Park, PhD, associate professor at the University of Hawaii at Manoa. The findings will be presented at NUTRITION 2025, the flagship annual meeting of the American Society for Nutrition.
The research utilized data from nearly 93,000 U.S. adults who reported information about their diet as part of a research cohort known as the Multiethnic Cohort Study. Over 21,000 of these participants developed Alzheimer's or related dementias in the years following.
The study discovered that participants who adopted the MIND diet most closely at the baseline had a 9% lower risk of dementia overall, with an even greater reduction (around 13%) among African American, Latino, and White groups. Baseline MIND diet adherence was not linked to a significant risk reduction among Native Hawaiian or Asian American participants.
Researchers observed that the protective effect of a healthy diet on dementia was more potent among African Americans, Latinos, and Whites, while it was not as prominent among Asian Americans and showed a weaker trend in Native Hawaiians. A tailored approach may be required when analyzing the diet quality of different subpopulations.
Additionally, researchers found that those who improved their adherence to MIND over ten years, including those who initially did not follow the diet closely, experienced a 25% lower risk of dementia compared to those whose adherence diminished. This trend held constant across various ages and racial groups.
However, scientists pointed out that differences in dietary patterns and preferences among various racial and ethnic groups could play a role in the variations they observed in the dementia-diet relationship.
In the future, further research might help clarify these patterns, and interventional studies would be necessary to confirm cause-and-effect associations since the study was based on observational data.

Overall:The MIND diet, or Mediterranean-DASH Intervention for Neurodegenerative Delay, emphasizes brain-supportive foods while minimizing those linked to cognitive decline. Its key components include leafy green vegetables, other vegetables, berries, nuts, beans, whole grains, fish, poultry, olive oil, red wine, red meat, butter, cheese, pastries, sweets, and fast food in moderation. Research demonstrates that strict adherence to the MIND diet is linked to a lower risk of dementia, particularly among Latino, white, and African American populations.
Evidence of Benefit Across Racial/Ethnic Groups:The MIND diet has shown connections with lower dementia risk across various racial and ethnic groups, especially among Latino, white, and African American populations. Though the association was weaker or not significant among Asian American and Native Hawaiian groups, the diet's benefits are still substantial for cognitive aging.
Food Components:The MIND diet prioritizes leafy green vegetables, berries, nuts, legumes, whole grains, fish, poultry, and olive oil, while limiting red meat, butter, cheese, pastries, sweets, and fast food. The potential health benefits and risks associated with red wine are mixed, but it is often omitted in recent large-scale studies due to potential health risks.
- Neuroscience news suggests a brain-saving diet, the MIND diet, may lower dementia risk, particularly among Latino, white, and African American populations.
- Improving adherence to the MIND diet over time may result in a 25% lower risk of dementia, regardless of age.
- The MIND diet emphasizes brain-supportive foods like leafy green vegetables, berries, nuts, and olive oil, while minimizing those linked to cognitive decline.
- It's never too late to adopt a healthy diet, the MIND diet in this case, to prevent dementia.
- Furthermore, science and health-and-wellness enthusiasts may find the research on the MIND diet and its impact on brain aging an interesting topic in the field of neuroscience. In fitness-and-exercise and mental-health circles as well, discussions about dietary patterns and their effects on cognitive aging can be valuable for overall health and wellness.
