11. OLIVE OIL
We have heard about the heart-healthy benefits of olive oil for many years now. The healthy fatty acids and antioxidants in olive oil are true health stars! Olive oil also contains polyphenols, which have been shown to keep blood vessels flexible.
12. GARLIC
This flavorful bulb does more than just make a mean pasta. Garlic contains nitric oxide, which has been shown to relax blood vessels. A recent review study found that garlic improves blood pressure in hypertensive patients similar to medications used for treatment. Kyolic garlic, in particular, has been shown to help with arterial stiffness and may even improve cholesterol levels.
