Higher olive oil intake was associated with a lower risk of dementia-related mortality, a prospective study of 90,000 healthcare professionals showed.
Eating at least 7 g of olive oil daily -- about a half tablespoon -- was tied to an adjusted 28% lower risk of dementia-related death (pooled hazard ratio
The relationship remained significant after adjusting for diet quality, including adherence to a Mediterranean diet, and after accounting for APOE4 gene status,
Replacing 5 g (about 1 teaspoon) of margarine and mayonnaise with the equivalent amount of olive oil daily was associated with an 8-14% lower risk of dementia mortality
Onset of most dementia types is gradual and progression is slow, making dementia-related mortality difficult to study, Tessier noted.
Typically, people who use olive oil for cooking or as a dressing have an overall better quality of their diet, but interestingly
