![]() Are Vegetable Oils as Healthy as You Think?.Plus, it develops earlier in life for African Americans than other races. That last part is important, too, because the prevalence of high blood pressure in African Americans is the highest in the world, according to the American Heart Association. They stated that this study provides evidence that a diet that includes EVOO can prevent cardiovascular disease in a multiethnic population. Neither diastolic blood pressure-the “bottom” number on a blood pressure reading-or arterial stiffness was affected, but the systolic results were enough to be promising, researchers concluded. The lower this number is (within a healthy range, of course, which is between 90 and 120 mmHg), the healthier your heart is. Systolic blood pressure is considered more important when looking at risk factors for cardiovascular disease, particularly for people over 50 since the number tends to rise with age as your arteries become stiffer. The researchers found a significant decrease in systolic blood pressure-the “top” number on a blood pressure reading that indicates how much pressure your blood is exerting against artery walls when the heart beats-with the higher polyphenol consumption. Then, they took a two-week break and switched to the other kind of EVOO for three more weeks. To determine whether polyphenols really make a difference on major cardiovascular measures like blood pressure and arterial stiffness, Australian researchers recruited 50 participants with an average age of 38, and had them consume 60 milliliters (mL) of either high polyphenol EVOO or a low polyphenol version for three weeks. The latter is the least processed, and it tends to be higher in a compound called polyphenols, which are micronutrients with antioxidant properties. ![]() Quick primer: There are three main grades of olive oil-refined, virgin, and extra virgin. Consuming two to four tablespoons of EVOO per day can keep your heart healthy in the long run.Įxtra virgin olive oil (EVOO) has often been associated with its heart-healthy benefits, but a recent study in the journal Nutrients offers further clarification, emphasizing that the type of EVOO you use actually does matter.According to recent research published in the journal Nutrients, consuming extra virgin olive oil (EVOO) can lower your systolic blood pressure-or the “top” number of a blood pressure reading that is important in determining your risk of heart disease.
