What is Kale?
Many of you will have heard of Kale – the superfood of superfoods! Today, it is well known that this cabbage-like plant contains numerous nutritional qualities that promote good health. You can find kale in just about any grocery store around the globe.
Kale is rich in calcium, vitamin K, folic acid, magnesium, and beta carotene. Kale is a source of two carotenoids, lutein and zeaxanthin. Kale, as with broccoli and other brassicas, contains sulforaphane (particularly when chopped or minced), a chemical with potent anti-cancer properties. Boiling decreases the level of sulforaphane; however, steaming, microwaving, or stir frying do not result in significant loss. Along with other brassica vegetables, kale is also a source of indole-3-carbinol, a chemical which boosts DNA repair in cells and appears to block the growth of cancer cells. Kale has been found to contain a group of resins known as bile acid sequestrants, which have been shown to lower cholesterol and decrease absorption of dietary fat. Steaming significantly increases these bile acid binding properties.
