1.Garlic
Garlic can add more than just zest to your dishes. It may also have a hand in boosting your nitric oxide levels, which dilates blood vessels. The more relaxed your blood vessels are, the less your heart has to work to pump blood through them. That helps keep your blood pressure down.
2.Go Green (and Leafy)
Salt makes your body hang on to more fluid. That bumps up your blood volume and the pressure on your arteries, which make your blood pressure climb. Fill your plate with leafy greens like spinach, broccoli, kale, or collards for a potassium boost. The mineral helps flush sodium out of your body through your pee and relaxes your blood vessel walls.
