4. Green Veggies
Powerhouse Profile: Broccoli is packed with sulforaphane, a compound that can protect against cancer or recurrences of certain cancers. Turn to dark, leafy greens like kale for anti-inflammatory vitamin K and lutein, a carotenoid that helps lower your risk of macular degeneration. Eat green for your heart, too.
Just one serving of raw greens a day (or ½ cup cooked) lowers your risk of heart attack by 23 percent, according to the Harvard Nurses' Health Study.
Bonus Tip: Steam broccoli until it becomes bright green; overcooking increases bitterness and zaps nutrients. Serve with whole grains, nuts, red peppers, or carrots if you don't like broccoli's natural flavor.
