If monounsaturated fats are the heart’s love potion, then polyphenols are its bodyguards. Polyphenols are natural compounds found in plants, and they’re particularly abundant in extra virgin olive oil. These compounds are powerful antioxidants, meaning they help protect your cells from damage caused by free radicals—those pesky molecules that can lead to oxidative stress, inflammation, and ultimately, chronic diseases like heart disease.

One of the most important polyphenols in olive oil is hydroxytyrosol. This compound has been shown to have potent anti-inflammatory and antioxidant effects, which can help protect your blood vessels from the damage that leads to atherosclerosis. Another key polyphenol in olive oil is oleuropein, which also boasts antioxidant properties and has been linked to improved heart health.

But the benefits of polyphenols don’t stop there. They also help improve the function of the endothelium, the delicate lining of your blood vessels. A healthy endothelium is crucial for maintaining proper blood flow and preventing the buildup of plaques. When the endothelium is damaged, it can’t do its job properly, leading to increased blood pressure and a higher risk of heart disease.

By including extra virgin olive oil in your diet, you’re essentially giving your heart a team of bodyguards—polyphenols that stand ready to protect your arteries, reduce inflammation, and keep your blood flowing smoothly. And who wouldn’t want a team of bodyguards looking out for their heart?
