A large study published in Nature Medicine suggests that following a Mediterranean-style diet may help reduce the risk of dementia, even for those with a high genetic predisposition. The diet, rich in vegetables, fruits, nuts, whole grains, and low in red and processed meats, was linked to slower cognitive decline over a period of three decades.
Diet Benefits Strongest for High-Risk Groups
The findings were particularly notable in people carrying two copies of the APOE4 gene variant, which can increase Alzheimer’s risk up to twelvefold. Researchers found that participants with healthier dietary patterns showed better long-term brain health, suggesting that lifestyle choices can counterbalance inherited risks. While the study mainly involved people of European ancestry, scientists believe the results highlight the potential of dietary strategies in reducing dementia risks and hope future research can expand these insights to more diverse populations.
