The adoption of the diet can reduce the risk of dementia at any age

Summary: A large study suggests that following the diet of the mind – rich in green leafy vegetables, berries, nuts and olive oil – reduces the risk of dementia to Alzheimer and dementia. Based on data from nearly 93,000 American adults, the researchers found the strongest and most consistent protective effects in African-American, Latin and white participants.

Those who have improved their diet for a decade experienced a risk of dementia up to 25% lower, whatever its age. Although the results are less pronounced in American and native Hawaiian participants, the study strengthens that the adoption of a brain health diet can benefit cognitive aging.

Key facts:

• Diet impact: Membership of the mind diet has reduced the risk of dementia by 9% overall.
• Improvement is important: Those who have improved their diet over time experienced a risk of 25%.
• Subgroup differences: The strongest effects observed in African-American, Latin and white groups.

As the American population is aging and dementia increases, many people ask if it is possible to prevent this devastating disease.

According to a new study, the answer can be on your plate: people who have followed a diet known as diet were much less likely to develop Alzheimer’s disease or related forms of dementia.

The plan of mind, which means a Mediterranean intervention for neurodegenerative deadlines, combines the Mediterranean diet with the dashboard hypotestly by blood pressure (food approaches to stop hypertension) and also emphasizes the food proven in brain like brain such as green leafy vegetables, berries, nons and olive oil.

According to the study, the food of the mind had a stronger and more coherent risk reduction relationship with dementia than other healthy regimes, although the relationship varied between five racial groups.

Those who have improved their membership in diet over time showed the largest risk reduction scheme. This beneficial relationship was observed in the same way among the younger and older groups, which suggests that there are advantages to adopting the diet at all ages.

“Our study results confirm that healthy diets in average to late life and their improvement over time can prevent Alzheimer’s disease and related dementia,” Song-Yi Park, PHD, associate professor at the University of Hawaii in Manoa.

“This suggests that it is never too late to adopt a healthy diet to prevent dementia.”

Park will present the 2025 nutrition results, the annual flagship meeting of the American Society for Nutrition held from May 31 to June 3 in Orlando, Florida.

Park and his colleagues analyzed data from nearly 93,000 American adults who provided information on their diet as part of a research cohort known as the multi -thnical cohort study from the 1990s. Participants were between 45 and 75 years old at the start and more than 21,000 dementia developed Alzheimer in the years that followed.

Overall, participants who obtained a higher score for adherence to the mind at the start had 9%

A lower risk of dementia, with an even greater reduction – more than 13% – among those who have identified as African -American, Latin or white. Membership of the diet of the basic spirit was not associated with a significant reduction in risks in Hawaiian or Aboriginal American participants.

“We found that the protective relationship between a healthy diet and dementia was more pronounced among African-Americans, Latinos and whites, when it was not as obvious among Americans of Asian origin and showed a lower trend in native Hawaiians,” said Park. “A tailor-made approach may be necessary when assessing the quality of the diet of different subpopulations.”

The results also showed that people who have improved their adhesion to the mind over 10 years (including those who did not follow the regime closely at first) had a risk of dementia at 25% lower compared to those whose membership decreased. This trend was consistent in different ages and racial groups.

Researchers said the differences in food regimes and preferences between racial and ethnic groups could play a role in the variation they observed in the dementia-demo relationship.

Since Americans of Asian origin also have lower dementia levels than other groups, it is possible that the diet of the mind does not reflect the advantages of more frequent regimes among this population.

Park said other studies could help clarify these models and add that interventional studies would be necessary to verify the cause and the effect, as the study was based on observation data.
