Light-to-moderate alcohol consumption is associated with a reduced risk of incident dementia and Alzheimer's disease, but evidence for vascular dementia is only suggestive.
If you already drink alcohol, light-to-moderate consumption (e.g., wine with meals) may be associated with a lower risk of Alzheimer's disease. Do not start drinking if you do not already. The evidence for vascular dementia is less clear.
ModerateQualifiesMEDIUM confidence
Light-to-moderate alcohol use may be associated with a reduced risk of incident dementia and AD, while for VaD, cognitive decline and predementia syndromes, the current evidence is only suggestive of a protective effect.
Why this rating
Based on epidemiological evidence, not RCTs.

- Adherence to a Mediterranean-type diet (MeDi) is associated with slower cognitive decline, reduced risk of progression from mild cognitive impairment (MCI) to Alzheimer's disease (AD), and reduced all-cause mortality in AD patients.Moderate
- High consumption of saturated fatty acids (SFA) is associated with negative effects on cognitive function and increased risk of dementia, whereas high intake of monounsaturated (MUFA) and polyunsaturated fatty acids (PUFA), particularly n-3 PUFA, is associated with reduced risk of cognitive decline.Moderate
