The results of this review suggest that higher adherence to the Mediterranean, DASH, or MIND diets is associated with less cognitive decline and a lower risk of Alzheimer’s Disease (AD). Evidence for an association with dementia was inconsistent.
The MIND diet may be more protective against cognitive decline and AD than the Mediterranean and DASH diets based on observational studies, but more evidence on the MIND diet is required to draw a firm conclusion. Furthermore, the Mediterranean diet seems more protective against AD than the DASH diet.
Based on the studies included in the current review, olive oil consumption seems to be an important component underlying these associations.
