Olive Oil
A key component of the Mediterranean diet, olive oil is rich in monounsaturated fats that promote healthy blood flow and reduce inflammation. Research has shown that people who consume olive oil regularly have a 41% lower risk of stroke. The polyphenols in olive oil have been found to improve endothelial function, keeping blood vessels flexible and reducing the risk of clot formation. Cooking with olive oil instead of butter or margarine can make a significant difference in long-term cardiovascular health. Including extra virgin olive oil in daily meals provides additional heart-protective benefits, especially when combined with a diet rich in vegetables and whole grains.
