Sweet potatoes
Sweet potatoes are one of your best bets for a fiber-rich vegetable side dish at dinner. A half-cup serving without the skin is packed with 1.8 grams of soluble fiber. Plus, sweet potatoes are full of antioxidants to help prevent plaque buildup.
Blueberries
Antioxidants also help blood vessels widen to keep your blood flow strong while reducing inflammation. Aim for seven to ten servings of fruits and veggies every day to help stave off stroke risk. A cup of blueberries counts as two servings toward your goal.
