Why: The leafy green is known as a superfood for a reason — it's got a bit of everything when it comes to nutrients, like omega-3s, fiber, and antioxidants, to name a few. Kale also contains a compound called glucoraphanin, which may help prevent plaque from building up in your arteries.
Look for: Steamed kale. To get the most heart-healthy effects from kale, try steaming it, so that the fiber compounds can bind together better. Not only does steaming help bring out kale's cholesterol-lowering abilities, but it can also make the leafy green taste less bitter than when it is eaten raw. For a health benefit, eat one and a half cups of kale (as well as other cruciferous veggies) two to three times a week.
