Story summary

A Mediterranean-style diet significantly lowers dementia risk, particularly for those genetically predisposed to Alzheimer's disease.
The study tracked 4,215 women and 1,490 men over three decades, examining diet's effect on cognitive decline.
Individuals with two copies of the APOE4 gene variant experienced the greatest protective benefits.
This diet, high in vegetables, fruits, and whole grains, helps regulate dementia-related metabolites.
Researchers recommend incorporating genetic and metabolite testing in Alzheimer's risk evaluations.
