Olive oil benefits brain

A new study suggests that high olive oil consumption is associated with a significant decreased risk for dementia-related mortality, regardless of overall diet quality.

Data from a prospective study of more than 92,000 people showed that consuming at least 7g of olive oil a day — about half a tablespoon — was associated with a 28% lower risk for dementia-related death. Replacing one teaspoon of margarine and mayonnaise with the equivalent amount of olive oil was associated with an 8%-14% lower risk for dementia-related mortality.

“Opting for olive oil, a natural product, instead of more processed fats such as margarine and mayonnaise, is a safe choice and may reduce risk of fatal dementia,” lead investigator Anne-Julie Tessier, RD, PhD, research associate, Department of Nutrition, Harvard T.H. Chan School of Public Health, Boston, told Medscape Medical News. However she added, “studies are needed to confirm causal effect and optimal quantity of olive oil intake.”

The study was published online in JAMA Network Open.
