A. Cruciferous Vegetables

Cruciferous vegetables are those that are part of the Brassica Genus. These vegetables are generally a good source of Vitamin C, Vitamin K, folate (Vitamin B), Carotenoids (chemicals in the plants that provide them with color), minerals, and Omega-3 fatty acids (healthy dietary fats).

These important nutrients present in kale and other cruciferous vegetables help maintain cognitive health, skin health, the health of the heart, etc. Adding more cruciferous vegetables to your diet can go a long way in increasing your life expectancy, owing to their anti-inflammatory, anti-cancer, and detoxifying properties.

Brussels sprouts, for example, can fight high blood pressure, high cholesterol, and cancer in the stomach, lungs, and/or prostate. Broccoli can help in improving the condition of your bowels and regulate your weight. Cauliflower may aid your immune system and prevent afflictions relating to the brain and cognition.

B. Nutritional Value of Kale

One of the benefits of Kale is that it is one of the most nutrient-dense foods that you can add to your diet. According to the U.S. Department of Agriculture, 100 grams of raw kale would consist of approximately 89.6 grams of Water, 2.9 grams of Protein, and 1.49 grams of Total Lipid (fat). It would also consist of 4.1 grams of Dietary Fiber (providing your body with roughage), and 2.4 mg of calcium(good for your bone health).

It also contains several other nutrients mentioned below :

1. Anti-Oxidants

Our body consists of “free radicals”, which are uncharged molecules that can harm the body and cause various illnesses and ailments. These may be produced during normal metabolic functions or due to activities such as – smoking, consuming alcohol and fried foods, exposure to X-Rays, air pollution, and industrial chemicals (some of which are also carcinogenic). These free radicals can be neutralized with the help of antioxidants.

Kale and other members of the cruciferous vegetable family have antioxidant properties, allowing them to give some of their electrons to the free radicals, thus, reducing the risk of several diseases.

2. Vitamin C

Kale is one of the best sources of Vitamin C for your body. One cup of kale may even have more Vitamin C than a whole orange, which makes it good for hair growth, reduces the risk of chronic illnesses, and promotes skin health.

3. Vitamin K

There are 390 micrograms of Vitamin K in 100 grams of raw kale, which help in the creation of various proteins that our body needs in order to prevent excessive bleeding, reduce the risk of fractures and improve the mineral density

4. Omega-3 Fatty Acids

Although it has very little fat, Kale contains Alpha-linolenic acid, a kind of Omega-3 fatty acid that promotes normal pumping of the heart and is essential for human growth. It also induces lower cholesterol, making it ideal for the rejuvenation of your arteries.

5. Potassium

Although other leafy greens are considered high-potassium foods, kale is classified as a lower-potassium food. This, however, could be because more than half a cup of kale can flare up some issues in your stomach or thyroid.

These nutrients play a great role in bringing about the benefits of kale.

C. Health Benefits of Kale

There are a lot of powerful medicinal properties and benefits of kale that can do wonders for your body if consumed daily. It has been considered a “superfood” by many doctors and experts in nutrition and diets. This is due to its high nutritional value and the fact that it is filled with vitamins and minerals.

Adding kale to your diet can cleanse and replenish your body. Just one cup of kale consumed every other day can increase your lifespan and improve your quality of life. The health benefits of kale are innumerable, owing to kale’s high vitamin and antioxidant levels.

Consuming vegetables such as spinach, kale, chard, and collard beans also support heart health and help the body generate new endothelial cells (that line the walls of arteries) and strengthen your blood vessels.

Eating kale every day can also result in lower levels of low-density lipoprotein or “bad” cholesterol that causes a sort of plaque build-up in the arteries, thereby lowering the risk of heart disease and other ailments such as high/low blood pressure, atherosclerotic cardiovascular disease, heart attacks, blood clotting, etc.

Kale helps in reducing HFD (High Fat Diet) induced inflammation and fat deposits in the body. Thereby inducing a lower risk of serious diseases such as fatty liver and obesity. The antioxidants present in kale can aid chronic liver problems and detoxify it.

E. Is It Safe to Eat Kale Raw?

Although raw kale may be a more nutritious alternative, it may also cause some damage to your thyroid function. It may be advisable to consume it raw in a more moderated fashion so as to reap the benefits of kale efficiently. Since it has a large amount of fibre, it may not be best for your stomach to be forced to digest it raw in large quantities.

You should also make sure that you wash kale thoroughly and dry it before tucking it in. You can store it in a refrigerator for about 6 days in an air-tight container or a ziplock bag. Always check for brown or black spots before you buy kale. Make sure it is fresh and has an earthy scent to it. As it gets older, it starts smelling of rotten eggs.

F. Raw Kale Versus Cooked Kale

Studies have shown that kale loses some of its antioxidants and nutrients when cooked. Although the results of each method of cooking are different, it has been observed that steaming is the most efficient method of retaining these qualities. Since it has a bitter taste, especially when fresh and eaten raw, cooking kale is preferred by most due to the subtlety it adds to the flavor.

Both raw, as well as cooked kale, are considered healthy. It is, however, a matter of which is healthier. When cooked, the vitamin C concentration decreases significantly, along with many other nutrients that make it such a healthy alternative. If seen from the digestion point of view, cooked kale may be favored instead.

G. Can You Ever Have “Too Much Kale”?

Although kale has many health benefits, having more than one or two helpings of it can have negative effects on your body. It may be best to stick with not more than half a cup of it. For one, it may cause gastrointestinal issues such as bloating, gas, constipation, and diarrhea.

It can also interfere with your thyroid function by blocking the iodine in your body if consumed in high quantities. As it consists of compounds known as goitrogens (that prevent the absorption of iodine by the thyroid gland) it can be particularly harmful to those who are iodine deficient (commonly found in those who have goitre).

However, adding iodine-rich foods to your diet may subside this hazard. You should discuss this with a healthcare professional and limit your kale consumption to a healthy amount.

It is also recommended that those who are using blood thinners steer clear of a diet containing a lot of kale. This is because it has an abundance of Vitamin K, which aids blood clotting. An increased intake of this vitamin may counteract the effect of the blood thinners. So long as you eat kale in limited quality, however, the benefits of kale would surpass its risks.
