Higher olive oil intake was associated with a lower risk of dementia-related mortality
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
The relationship remained significant after adjusting for diet quality, including adherence to a Mediterranean diet,
Replacing 5 g (about 1 teaspoon) of margarine and mayonnaise with the equivalent amount of olive oil daily was associated
Substitutions for other vegetable oils or butter were not significant.
Onset of most dementia types is gradual and progression is slow, making dementia-related mortality difficult to study
Tessier noted. "To our knowledge, this is the first study to examine diet, specifically olive oil, in relation to dementia death," she told MedPage Today.
Typically, people who use olive oil for cooking or as a dressing have an overall better quality of their diet
