You may lower your risk of cardiovascular disease.
While many types of fat, including saturated fats and trans fats, have been linked to heart disease and arterial plaque, olive oil has some major benefits for your cardiovascular health.
According to a 2020 study published in the journal Circulation, individuals who consumed more than half a tablespoon of olive oil on a daily basis slashed their risk of coronary heart disease by 21% and their risk of any type of heart disease by 15%.
A 2011 study published in the journal Neurology also found that, among a group of 7,625 people age 65 or older, after adjusting for other risk factors including BMI and physical activity levels, individuals who regularly consumed olive oil had a 41% lower risk of stroke than those who reported never consuming it.
You may lower your blood pressure.
Approximately 45% of the U.S. adult population has high blood pressure, a condition that can increase your risk of heart attack and stroke—but adding some olive oil to your diet may help. A 2020 study published in the journal Nutrients found that, among a group of 50 adult study participants, those who consumed approximately two ounces of high-polyphenol extra virgin olive oil per day significantly reduced both their peripheral and central systolic blood pressure.
You may experience reduced inflammation.
If you're experiencing inflammation, whether it's joint pain or arterial inflammation due to plaque, olive oil consumption may benefit you.
A 2018 review published in the journal Endocrine, Metabolic & Immune Disorders – Drug Targets found that consumption of extra virgin olive oil reduced inflammatory biomarkers associated with atherosclerosis, the hardening of arteries due to plaque buildup. Additionally, a study published in the journal Nature found that extra virgin olive oil has anti-inflammatory properties similar to that of ibuprofen, thanks to its wealth of oleocanthal, a phenolic compound.
