Many people have heard of it, but don't know exactly what is kale. Increasingly, however, the health benefits of kale are being reported in major outlets, whether the general media or scientific journals.

The light that is currently being shed on kale is that it is one of the most potent health promoting vegetables known to man.

Kale is similar to other nutritional powerhouses, especially cabbage relatives like broccoli. However, it doesn't resemble broccoli in appearance, having lovely dark green leaves instead of a miniature tree-like look.

Scientifically speaking, what is kale? It's a veggie that belongs to the Brassica family (also included in this family are such notables as brussel sprouts and collards).

Kale has an earthy flavor that some people enjoy, but others find unappetizing.

What is Kale: A Short History

Kale originated in Asia Minor and descended from a wild cabbage. Celtic roamers introduced Europe to Kale around 600 BC, and it thrived on the coastal southern and western regions. In time, it became a popular vegetable.

Sometime in the 17th century it was brought to the United States by some of the early English settlers.

What is Kale: Kale and Immune System Because Kale is brimming with antioxidants, such as A, C, and E, many people are hoping there is a kale and immune system boosting connection.

Although no studies have been done to date that we know of testing kale's ability to boost one's immune system, it is well known that the immune system does need Vitamins A, C, and E for proper and optimal functioning.

Benefits of Kale

The health benefits of kale are attributed to sulfur-containing phytonutrients. These substances, according to research, appear to be able to reduce the occurrence of numerous types of cancers.

The exact mechanism is unclear....but researchers have concluded that such compounds in kale may trigger enzymes in the body that help to counter cancer promoting substances.

Kale, therefore, seems a great addition to any anti-cancer diet.

Its benefits don't just end there, however. Kale is also an excellent source of fiber, which is an important consideration for the millions of people who suffer from elevated cholesterol levels and in helping cleanse the colon.

Many people, when they think of sources of calcium, believe dairy products are the best choice. But the truth of the matter is that dark leafy vegetables like kale, broccoli, and spinach are better sources of calcium.

Another important consideration is that kale is extremely sparse on calories, has no saturated fat, and does not cause widespread allergic reactions like many diary products do.

In short, with kale, you can obtain your needed calcium without the guilt.
