Takeaway
Following a Mediterranean-like diet can protect against memory decline and mediotemporal atrophy in people at high risk of developing Alzheimer’s disease.
Why this matters
These important findings suggest that following a Mediterranean-like diet is a protective, modifiable lifestyle factor against Alzheimer’s disease-related neurodegeneration and memory decline. These benefits appear to be mediated by a reduction in amyloidosis and tau-pathology, suggesting that dietary interventions could help to delay Alzheimer’s disease in at-risk individuals.
