Considered a super food, Kale is rich in vitamin E, potassium, folate, fiber, omega-3 fatty acids and antioxidants. These nutrients are essential for heart health. Also, Kale is a good source of lutein, a nutrient known for its protection properties against atherosclerosis. Moreover, this dark leafy green also contains a compound called glucoraphanin, which activates the Nrf2 – a protective protein that coats the arteries, keeping the plaques from developing inside the artery walls. This compound keeps the arteries clear and allows the oxygen-carrier blood to flow without obstruction, thus keeping heart attacks or any other heart disease at bay. Kale can be consumed cooked, raw, dehydrated or juiced.
