Kale is packed with nutrients
Kale contains four times as much vitamin C and twice as much selenium as spinach, along with nutrients like vitamin E and beta-carotene. Kale is packed with nutrients like vitamin K and carotenoids that have impressive benefits. Adding kale to your diet can provide you with plenty of vitamin C. It can help improve blood circulation and reduce mental stress.
Mix kale with foods rich in vitamin C, which helps the body absorb more iron. Kale is a good source of beta-carotene, a carotenoid that the body converts into vitamin A when it needs it. The high concentration of vitamin A found in kale helps improve and maintain healthy eyes and skin.
Trista Best, MPH, RD, LD, with Balance One Supplements, also shows that a cup of kale can not only provide your body with enough vitamin C, but also provide your body with two to six times the vitamin.
