7. Berries

Small, sweet, and surprisingly powerful berries pack one of the highest antioxidant counts of any fruit. The pigment that gives blueberries, blackberries, and strawberries their deep color is called anthocyanin, and it’s been shown to improve how well your blood vessels function while reducing the oxidative stress that contributes to plaque formation. Studies tracking regular berry eaters have found measurable drops in blood pressure over time. A cup of mixed berries a few times a week does the job — fresh or frozen both count, so there’s no excuse in the off-season. Sprinkle them over your morning oats and you’ve doubled up on heart protection in one bowl.
