15 indisputable health benefits of kale

Once again called the Queen of Green Vegetables, the kale is a food-rich food. It also stands as one of the healthiest foods in the world, as nutrients it contains promote the health of hair, bones and skin.

The fibre content also improves digestion and contributes significantly to cardiovascular health. Let’s find out the 15 benefits of the kale.

15 indisputable health benefits of kale

Protects against diabetes

The fibres and antioxidants contained in kale can provide protection against diabetes. Studies have shown that high fibre intake can reduce blood glucose levels in people with type 1 diabetes.

For people with type 2 diabetes, they can see an improvement in lipids, insulin levels and blood glucose levels.

One cup of this food, weighing about 16 g provides 0.6 g of fibre.

A cup of this cooked vegetable (about 130 g) provides 2.6 g of fibre.

This variety of cabbage also contains an antioxidant known as lipoic acid or alpha-lipoic acid.

Studies also suggest that this can help lower glucose levels, increase insulin sensitivity and prevent changes induced by oxidative stress in diabetic patients.

It can also reduce peripheral neuropathy and autonomic neuropathy in the latter.

This food can therefore contribute to a healthy daily intake of alpha-lipoic acid, which is also produced naturally in our body.

Fight cancer

The chlorophyll of kale (and other green vegetables) helps prevent the organism from absorbing the compounds called heterocyclic amines.

These are chemicals associated with cancer, which are produced by grilling food of animal origin at high temperatures. Thus, when this chlorophyll binds to carcinogens, it also prevents them from being absorbed.

According to the National Cancer Institute, Brassica vegetables such as kale help fight cancer. They also contain substances called glucosinolates, which play an important role in the prevention of cancer.

Reduces the risk of heart disease

Potassium, vitamin B6, fibres and vitamin C found in kale can improve heart health.

It is advisable to increase the intake of potassium, while reducing the intake of sodium to reduce the risk of cardiovascular disease.

According to one study, participants who consumed about 4 g of potassium per day had a risk of death from heart disease of less than 49%, compared to those who consumed about 1 g per day.

High potassium intake is also associated with reduced risk of stroke, protection against muscle mass loss, preservation of bone mineral density, and reduction of kidney stones formation.

To decrease blood pressure, it may also be important to consume more potassium than to decrease sodium intake, as potassium dilates the blood vessels.

This vegetable can therefore help to increase your potassium consumption. Indeed:

  • One cup of this variety of chopped fresh cabbage contains about 79 mg of potassium;
  • A cup of this cooked food delivers about 296 mg of potassium.

A high potassium intake will therefore decrease the risk of death by about 20%, all causes combined.

Fights inflammation

This could be the most beneficial property of kale. We know the importance of a balance between omega-3 and omega-6 fatty acids in our body. This vegetable thus promotes this balance.

These anti-inflammatory properties of this vegetable also make it an ideal food to relieve the symptoms of arthritis.

Ensures Bone health

Some research has suggested that a low vitamin K intake is associated with a higher risk of bone fracture.

Although the human body creates most of the K vitamins it needs, an appropriate consumption of K vitamins is important for good health.

It helps to modify the proteins of the bone matrix, improves the absorption of calcium and can reduce the amount of calcium excreted in the urine.

Help with Detoxification

This can be attributed to the fibres contained in kale. Indeed, this variety of cabbage promotes regularity and helps the body to detox.

Although these two antioxidants are not synthesized in the body, this variety of cabbage is rich.

By consuming this vegetable, lutein and zeaxanthin will help your body prevent serious eye diseases such as cataracts and age-related macular degeneration.

It has also been proven that people aged 40 to 59 years can reduce their risk of macular degeneration by consuming this vegetable.

Improves skin and hair health

Kale is rich in beta-carotene, which is converted to vitamin A by the body. This nutrient ensures the growth of all body tissues, including hair and skin.

It is also essential for the production of sebum, the oil that helps to keep the hair and skin hydrated. The immune function, the reproductive function and the view also depend on vitamin A.

A cup of this cooked food also contains 53.3 mg of vitamin C, which is necessary to build and preserve the collagen, essential protein on which the structure of the bones, skin and hair rests.

In addition to vitamin C, this variety of cabbage also contains iron. Adequate iron intake can help prevent anemia.

Improves Brain health

Needless to stress the importance of omega-3 for the health of the brain. In kale, omega-3s can help lower blood glucose levels, which promotes the aging of brain cells and worsens the health of neurons.

In addition, this vegetable is also rich in vitamin K, necessary for the production of Sphingolipids, which are complex lipids responsible for the structure of the brain cells.

The high intake of vitamin C is what needs to be examined when you want to increase the performance of your immune system. However, kale is rich in vitamins C, as well as folic acid, which is another stimulant of the immune system.
