A new study has found that a Mediterranean diet rich in plant-based foods and healthy fats can significantly lower the risk of dementia in genetically vulnerable adults. The research, published in the journal Nature, followed over 5,700 people for 34 years and discovered that those who adhered to a Mediterranean diet with minimal alcohol consumption, reduced red and processed meat intake, but increased vegetable, fruit, nut, whole grain, legume, fish, and olive oil consumption were 35% less likely to develop dementia.
The study found that the APOE4 gene, which is a major risk factor for Alzheimer’s disease, was particularly responsive to the Mediterranean diet. Individuals with two copies of the APOE4 gene who stuck to the diet experienced even greater reductions in dementia risk, highlighting the importance of adhering to this dietary pattern.
The Mediterranean diet has been shown to have numerous health benefits, including slowing cognitive decline and supporting brain function. Its high levels of healthy unsaturated fats, such as omega-3 fatty acids, are thought to be particularly beneficial for brain health.
This finding provides hope for those at risk of dementia, particularly those with a genetic predisposition to the condition. By incorporating more Mediterranean-style eating into their diet, individuals may be able to lower their risk of developing dementia and improve their overall well-being.
