Mediterranean Diet: Supports Brain Health A new study offers hope for people worried about their risk of dementia: what you eat might help protect your brain, even if you have genes that put you in the highest risk category for Alzheimer’s . Researchers from Mass General Brigham, Harvard, and the Broad Institute tracked thousands of adults for decades. They found that people who stuck to a Mediterranean-style diet—a way of eating rich in fruits, veggies, whole grains, nuts, fish, and olive oil—were less likely to develop dementia and experienced slower memory decline. The effect was powerful in those with two copies of the APOE4 gene, the variant most closely linked to Alzheimer’s disease. The science here is striking. People with one copy of APOE4 have a three-to-four times greater risk for Alzheimer’s; two copies raise the risk to twelve times higher than average. This study suggests that a healthy diet can actually help offset some of that genetic risk. Researchers believe tha...
