19. Kale
Often used as an adornment for other dishes, kale is a super healthy veggie, so instead of pushing it off your plate, you should seriously consider eating it. A cup of cooked kale has about 885 mcg of vitamin A, or around 98 percent of the recommended daily intake.
This dark green, leafy veggie is also rich in potassium, vitamin E, vitamin C, vitamin K, folate, protein, phosphorus and omega 3 fatty acids. Steam it up for a healthy side dish, mix it in with other greens for a salad, or make some baked kale chips for a snack.
