Story summary

2025 Nature Medicine study finds a Mediterranean diet may lower dementia risk, especially for APOE4 carriers.
The study followed over 5,000 participants for three decades, linking adherence to fewer dementia diagnoses.
Researchers identified 57 metabolites with dementia-risk links that varied by genetic profile, especially APOE4.
Combining genetic, metabolic, and dietary data improved risk prediction, but limits include ancestry and self-report.
