Research followed 57-hundred people for more than three decades.

If you’re at risk for dementia, you might want to check out the Mediterranean diet. A new study finds the diet lowers risk of dementia — especially people with the APOE4 gene. The gene is a major genetic risk factor for alzheimer’s disease.

The Mediterranean diet is plant-based — full of fish, vegetables, fruits, nuts, whole grains, legumes and olive oil. The diet also calls for little to no alcohol or red and processed meat. Researchers found that people with two APOE4 genes reduced their probability of developing dementia by at least 35-percent when following the diet. The research followed 57-hundred people for more than three decades.
