Study Reveals Olive Oil May Boost Brain Health in Dementia Patients

Olive Oil

Instead of margarine or mayonnaise, researchers have found a link between daily olive oil use and a lower risk of dementia-related death.

The World Health Organisation (WHO)Trusted Source estimates that about 55 million individuals worldwide suffer from dementia. Dementia is the fifth biggest cause of death for senior citizens, with an estimated 10 million new cases per year.

Alzheimer’s disease (AD), the most common type of dementia, is thought to affect 6.7 million Americans over the age of 65.

According to a news release, the new study discovered that those who used olive oil on a regular basis had a 28% lower risk of passing away from dementia than those who did not.

The study looked at health records from 1990 to 2018 for 31,801 men and 60,582 women who were free of cancer or cardiovascular disease. We monitored their health for 28 years.

According to the study’s authors, swapping just one teaspoon of margarine or mayonnaise for olive oil was linked to an 8–14% lower risk of dementia-related death.

In their study, Dr. Tessier and her associates discovered that the link between olive oil and a lower risk of dementia-related death persisted independent of the quality of the subjects’ diets, including how strictly they followed the Mediterranean diet. “Given that olive oil is the primary source of added fat in a typical Mediterranean diet, we were interested in examining its association with fatal dementia,” Dr. Tessier told.
