Can olive oil help lower the risk of dementia-related death?

• Researchers are reporting that consuming about half a tablespoon per day of olive oil might reduce the risk of dementia-related death.
• They noted that diet quality did not affect the benefits of olive oil.
• Other studies have shown olive oil helps lower the risk of death from cardiovascular disease, cancer, neurodegenerative disease, and respiratory disease.

A higher intake of olive oil is associated with a lower risk of dementia-related mortality, according to a studyTrusted Source published today in the journal JAMA Network Open.

Researchers used information from two large prospective cohorts in the United States —the Nurses’ Health Study and the Health Professionals Follow-Up Study.

They said they found that people who consumed more than 7 grams of olive oil daily (about half a tablespoon) had significantly lower dementia-related mortality rates than those who consumed less than 7 grams.
