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.
Adopt a Mediterranean-style eating pattern as your primary dietary strategy for brain health. Focus on high consumption of vegetables, fruits, nuts, legumes, and cereals, using olive oil as your main fat source. Include moderate amounts of fish and, if you drink alcohol, limit it to moderate levels (e.g., wine with meals). This pattern is associated with slower cognitive decline and lower risk of Alzheimer's disease.
recent prospective studies provided evidence that higher adherence to a Mediterranean-type diet could be associated with slower cognitive decline, reduced risk of progression from MCI to AD, reduced risk of AD and a decreased all-cause mortality in AD patients.
Why this rating

- 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
- 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.Moderate
