A new study published in Nature reveals that the Mediterranean diet may significantly reduce dementia risk, especially for individuals with the APOE4 gene, a major Alzheimer's risk factor. Researchers tracked 5,700 people for over 30 years and found that those with two APOE4 genes who followed the diet lowered their dementia risk by at least 35%. The diet focuses on plant-based foods like fruits, vegetables, fish, and olive oil, while limiting red meat and alcohol.
