This study found that following a Mediterranean-style diet may help protect against dementia, particularly in people with the highest genetic risk for Alzheimer’s disease. Tracking over 5,700 participants across two long-running U.S. health studies, it showed that individuals with two copies of the high-risk APOE4 gene variant – who face a twelvefold greater likelihood of developing Alzheimer’s – experienced the strongest protective effect from adhering to the diet.
The researchers examined dietary patterns, genetic data, and blood metabolites to better understand how food interacts with biological processes linked to cognitive health. Participants who followed the Mediterranean diet most closely not only had a lower risk of dementia but also showed slower rates of cognitive decline. The findings provide further evidence that nutrition plays a crucial role in offsetting the genetic and metabolic risks of Alzheimer’s, with diet influencing key pathways tied to brain function.
