Adherence to Mediterranean (MD) and DASH dietary patterns is associated with slower cognitive decline and reduced risk of Alzheimer's disease, primarily through the inhibition of neuroinflammatory processes via anti-inflammatory nutrients like polyphenols and omega-3 fatty acids.
Adopt a Mediterranean or DASH-style diet rich in fruits, vegetables, whole grains, nuts, and fish. This approach is more effective for cognitive health than taking isolated supplements because the combination of nutrients works synergistically to reduce brain inflammation.

Anti-inflammatory dietary patterns such as the Mediterranean diet (MD) and dietary approaches to stop hypertension (DASH) may be neuroprotective. Several dietary components consumed in the MD and DASH (omega-3 fatty acids, antioxidants and polyphenols) can inhibit neuroinflammation associated with AD.
Why this rating
Evidence is largely observational with inconsistent RCT results; the paper notes 'data from human studies are lacking' for causal links.
