Higher olive oil consumption linked with lower risk of premature death

Boston, MA – People who consume higher amounts of olive oil may lower their risk of premature death overall and from specific causes including cardiovascular diseasecancer, and neurodegenerative disease, compared to people who never or almost never consume olive oil, according to a new study led by researchers from Harvard T.H. Chan School of Public Health. The researchers also found that people who consumed olive oil instead of animal fat had a lower risk of total and cause-specific mortality.

The study was published online January 10, 2022 in the Journal of the American College of Cardiology.

This is the first long-term observational study on olive oil consumption and mortality in the U.S. Most previous research on olive oil and health has focused on populations from Europe and the Mediterranean, where olive oil consumption is higher.

“Olive oil consumption has been linked to lower cardiovascular disease risk, but its association with premature death was unclear,” said Marta Guasch-Ferré, a senior research scientist in the Department of Nutrition at Harvard Chan School. “Our findings confirm current dietary recommendations to replace animal fats with plant oils for the prevention of chronic diseases and premature death.”

The researchers used health data collected between 1990 and 2018 for 60,582 women participating in the Nurses’ Health Study and 31,801 men in the Health Professionals Follow-up Study. All participants were free of cardiovascular disease or cancer at the beginning of the study and completed dietary questionnaires every four years. During the study period, 36,856 people died.

Participants were asked how often they used olive oil in salad dressings, added to food or bread, or in baking or frying. According to the findings, people in the highest category of olive oil consumption (more than seven grams per day) had 19% lower risk of total and cardiovascular disease mortality, 17% lower risk of cancer mortality, 29% lower risk of neurodegenerative mortality, and 18% lower risk of respiratory mortality, compared with those who never or rarely consumed olive oil. Compared to margarine, butter, mayonnaise, or dairy fat, the use of olive oil was associated with lower risk of total and cause-specific mortality, although no significant risk reduction was observed when use of olive oil was compared to use of other vegetable oils.

“Clinicians should be counseling patients to replace certain fats, such as margarine and butter, with olive oil to improve their health,” Guasch-Ferré said. “Our study helps make specific recommendations that will be easy for patients to understand and hopefully implement into their diets.”
