Adherence to a Mediterranean-style diet significantly reduces systolic and diastolic blood pressure in adults without established cardiovascular disease (primary prevention).

To lower your blood pressure, adopt a Mediterranean-style diet. This means using olive oil as your main cooking fat, eating plenty of fruits, vegetables, and legumes, and including tree nuts. This approach has been shown to modestly but significantly reduce both systolic and diastolic blood pressure in people at risk of heart disease.
