Kale is being called “the new beef”, “the queen of greens” and “a nutritional powerhouse.” kale is an amazing vegetable being recognized for its exceptional nutrient richness, health benefits, and delicious flavor. Eating a variety of natural, unprocessed vegetables can do wonders for your health, but choosing super-nutritious kale on a regular basis may provide significant health benefits, including cancer protection and lowered cholesterol.
Kale, also known as borecole, is one of the healthiest vegetables on the planet. A leafy green, kale is available in curly, ornamental, or dinosaur varieties. It belongs to the Brassica family that includes cruciferous vegetables such as cabbage, collards, broccoli, and Brussels sprouts.
Kale can provide you with some special cholesterol-lowering benefits if you will cook it by steaming. The fiber-related components in kale do a better job of binding together with bile acids in your digestive tract when they’ve been steamed. When this binding process takes place, it’s easier for bile acids to be excreted, and the result is a lowering of your cholesterol levels. Raw kale still has cholesterol-lowering ability—just not as much.
Kale’s risk-lowering benefits for cancer have recently been extended to at least five different types of cancer. These types include cancer of the bladder, breast, colon, ovary, and prostate. Isothiocyanates (ITCs) made from glucosinolates in kale play a primary role in achieving these risk-lowering benefits.
Kale is now recognized as providing comprehensive support for the body’s detoxification system. New research has shown that the ITCs made from kale’s glucosinolates can help regulate detox at a genetic level.
Researchers can now identify over 45 different flavonoids in kale. With kaempferol and quercetin heading the list, kale’s flavonoids combine both antioxidant and anti-inflammatory benefits in way that gives kale a leading dietary role with respect to avoidance of chronic inflammation and oxidative stress.
Kale or borecole is a vegetable with green or purple leaves, in which the central leaves do not form a head. It is considered to be closer to wild cabbage than most domesticated forms. The species Brassica oleracea contains a wide array of vegetables, including broccoli, cauliflower, collard greens, and brussels sprouts. The cultivar group Acephala also includes spring greens and collard greens, which are extremely similar genetically.
Kale freezes well and actually tastes sweeter and more flavourful after being exposed to a frost. Tender kale greens can provide an intense addition to salads, particularly when combined with other such strongly flavoured ingredients as dry-roasted peanuts, tamari-roasted almonds, red pepper flakes, or an Asian-style dressing. When combined with oils or lemon juice, kale’s flavor is noticeably reduced. When baked or dehydrated, kale takes on a consistency similar to that of a potato chip. Curly kale varieties are usually preferred for chips. The chips can be seasoned with salt or other spices.
In the Netherlands, it is very frequently used in a traditional winter dish called stamppot boerenkool, which is a mix of kale and mashed potatoes, sometimes with fried bits of bacon added to it.
In Ireland, kale is mixed with mashed potatoes to make the traditional dish colcannon. It is popular on Halloween when it is sometimes served with sausages. Small coins are sometimes hidden inside as prizes. A variety of kale, kai-lan, is a very popular vegetable in China, Taiwan, and Vietnam, where it is commonly stir-fried with beef.
A traditional Portuguese soup, caldo verde, combines pureed potatoes, diced kale, olive oil, broth, and, generally, sliced cooked spicy sausage. In Brazil, where it was introduced by the Portuguese, it is an indispensable side dish for the national stew feijoada.
In the eastern African Great Lakes region, it is an essential ingredient in making a stew for ugali, which is almost always eaten with kale. Kale is also eaten throughout southeastern Africa, where it is typically boiled with coconut milk and ground peanuts and is served with rice or boiled cornmeal. In Italy, kale (cavolo nero) is part of many dishes, such as “casseula” (pork stew), polenta (corn porridge) with kale, Parmesan cheese and olive oil and “pizzoccheri”, buckwheat tagliatelle served with kale, melted fontina cheese and potatoes.
A whole culture around kale has developed in north-western Germany around the towns of Bremen, Oldenburg and Hannover. There, most social clubs of any kind will have a Grünkohlessen or Kohlfahrt (“kale tour”) sometime between October and February, visiting a country inn to consume large quantities of kale stew, Pinkel sausage, Kassler, Mettwurst and Schnapps. These tours are often combined with a game of Boßeln. Most communities in the area have a yearly kale festival which includes naming a “kale king” (or queen).
Curly kale is used in Denmark and southwestern Sweden (Scania, Halland and Blekinge) to make langkål (Danish) or långkål (Swedish), an obligatory dish on the julbord in the region, and is commonly served together with the Christmas ham (Sweden). The kale is used to make a stew of minced boiled kale, stock, cream, pepper and salt that is simmered together slowly for a few hours. In Scotland, kale provided such a base for a traditional diet that the word in dialect Scots is synonymous with food. To be “off one’s kail” is to feel too ill to eat. In Sweden, it is also commonly eaten as a soup, with a base of ham broth and the addition of onion and pork sausages.
In Montenegro collards, kale, locally known as rashtan, is a favorite vegetable. It is particularly popular in the winter, cooked with smoked mutton (kastradina) and potatoes.
In the Southern United States, kale is often served braised, either alone or mixed with other greens, such as collard, mustard, or turnip.
In Japan, kale juice (known as aojiru) is a popular dietary supplement.
Kale is very high in beta carotene, vitamin K, vitamin C, and rich in calcium. 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
Many varieties of kale and cabbage are grown mainly for their ornamental leaves, which are brilliant white, red, pink, lavender, blue or violet in the interior of the rosette. Ornamental kale is as edible as any other variety.

Interesting comparision about Kale
1. It has more vitamin C than an orange. One cup of chopped kale has 134 percent of your recommended daily intake of vitamin C, while a medium orange fruit has 113 percent of the daily C requirement. That’s particularly noteworthy because a cup of kale weighs just 67 grams, while a medium orange weighs 131 grams. In other words? Gram for gram, kale has more than twice the vitamin C as an orange.
2. It’s…kind of fatty (in a good way!). We don’t typically think of our greens as sources of even healthful fats. But kale is actually a great source of alpha-linoleic acid (ALA), which is a type of omega-3 fatty acid that’s essential for brain health, reduces Type 2 diabetes risk, and boots heart health as well. Each cup has 121mg of ALA.
3. It might be the queen of vitamin A. Kale has 133 percent of a person’s daily vitamin A requirement—more than any other leafy green.
4. Kale even beats milk in the calcium department. It’s worth noting that kale has 150mg of calcium per 100 grams, while milk has 125mg.
5. It’s better with a friend. Kale has plenty of phytonutrients, such as quercetin, which helps combat inflammation and prevent arterial plaque formation, and sulforaphane, a cancer-fighting compound. But many of its top health-promoting compounds are rendered more effective when you eat the stuff in combination with another food. Pair kale with fats like avocado, olive oil, or even parmesan to make fat-soluble carotenoids more available to the body. And acid from lemon juice helps make kale’s iron more bioavailable as well.
6. The leafy green is more likely to be ‘dirty.’ According to the Environmental Working Group, kale is one of the most likely crops to have residual pesticides. The organization recommends choosing organic kale (or growing it yourself!).
One cup of chopped kale contains 33 calories and 9% of the daily value of calcium, 206% of vitamin A, 134% of vitamin C, and a whopping 684% of vitamin K. It is also a good source of minerals copper, potassium, iron, manganese, and phosphorus.
Kale’s health benefits are primarily linked to the high concentration and excellent source of antioxidant vitamins A, C, and K — and sulphur-containing phytonutrients.
Carotenoids and flavonoids are the specific types of antioxidants associated with many of the anti-cancer health benefits. Kale is also rich in the eye-health promoting lutein and zeaxanthin compounds. Beyond antioxidants, the fiber content of cruciferous kale binds bile acids and helps lower blood cholesterol levels and reduce the risk of heart disease, especially when kale is cooked instead of raw.
Eating a diet rich in the powerful antioxidant vitamin K can reduce the overall risk of developing or dying from cancer, according to a study in the American Journal of Clinical Nutrition. Vitamin K is abundant in kale but also found in parsley, spinach, collard greens, and animal products such as cheese.
Vitamin K is necessary for a wide variety of bodily functions, including normal blood clotting, antioxidant activity, and bone health. But too much vitamin K can pose problems for some people. Anyone taking anticoagulants such as warfarin should avoid kale because the high level of vitamin K may interfere with the drugs. Consult your doctor before adding kale to your diet.
Kale might be a powerhouse of nutrients but is also contains oxalates, naturally occurring substances that can interfere with the absorption of calcium. Avoid eating calcium-rich foods like dairy at the same time as kale to prevent any problem.
