Another study also found that eating steamed kale helps to lower the bad cholesterol levels by raising the effect of bile acid binding in the alimentary canal.

By lowering the bad cholesterol levels in the body, consuming kale also helps to keep the heart in good shape by protecting from cardiovascular diseases. Moreover, the high vitamin K level in kale helps in preventing atherosclerosis.

  • As an anti-depressant

Symptoms of depression can be reduced by eating kale. This is because kale has omega-3 fatty acids that help in treating depression.

  • Prevention of diabetes

Type 2 diabetes is caused by several factors including a deficiency in minerals like magnesium, which is found in kale. This deficiency leads to an increase in fasting blood glucose levels that is the major cause of diabetes. Besides, kale is considered as a low-glycemic-index food ? foods with low sugar content ? and helps in lowering the blood sugar level. Thus, by eating high fiber foods, diabetics can effectively control their fasting blood sugar levels while non-diabetics can lower the risk of the disease.

Pregnant women are advised to add kales in their daily diet so as to promote the proper development of the fetus (the unborn child).

Kale is packed with anti-cancer compounds like sulforaphane, which is believed to have cancer-fighting properties.

  • For detoxification

Thanks to the isthiocyanates found in kale, eating this leafy vegetable can help to cleanse the body of toxins. These ishtiocyanates are also beneficial in the destruction of carcinogenic compounds in the body and help to protect the body from the effects of free radicals.

The presence of vitamins A and C in kale help to strengthen the body?s immune system. Kale is rich in vitamin C (more than that in spinach and as much as that in orange) which is a powerful antioxidant that is important for staving off diseases like common cold and skin diseases.

  • For healthy skin

Besides the immunity-boosting properties of vitamin C, it is also beneficial to skin health. Skin problems like sunburn or dry skin can be prevented by eating vitamin C-rich foods like kale. It has already been stated that kale contains as much vitamin C content as orange; hence, eating enough kale can do wonders to the skin.

  • Aids proper digestion

  • Good for the bones

Kale contains about 90 mg of calcium, which is about 9% of the required daily value. Calcium is essential for strong bones and a deficiency of this mineral has been linked with bone diseases like osteoporosis. Furthermore, the high vitamin K content in kale helps to increase the absorption of calcium in the bones. According to a report, a cupful of cooked kale has been shown to contain as much calcium as a cup of cow milk.

Commons side effects of eating kale

Eating kale is highly nutritious to the body, but when you eat more than is required by your body there are risks and possible side effects. Some of the common side effects of overeating kale are:

  • Dehydration:

While kale increases the frequency of urinating, overconsumption of this vegetable can cause dehydration. This is because as a diuretic, kale promotes the release of water and too much of it can lead to loss of water from the body.

  • Allergic reactions

It has been found that some persons can develop allergic reactions to kale. While kale contains several nutrients that benefit the body, the risk of allergies to certain individuals should be considered.

  • Hypoglycemia and hypotension

Excess consumption of low-glycemic-index foods can result in a condition of low blood sugar level or hypoglycemia while overeating foods that can lower the blood pressure may lead to hypotension. Kale fits into these two categories (low sugar and low cholesterol) and, hence, eating too much kale is not recommended.

  • Risk of digestion problems

Though foods rich in fiber are beneficial for digestive health as fiber is essential for proper digestion, an excess consumption of these foods increase the risk of developing other digestion problems like indigestion. Moreover, eating too much fiber foods without taking an adequate amount of water can increase the risk of constipation and dehydration.

Kale is a member of the Cruciferae vegetable family that also includes broccoli. This leafy vegetable has been shown to contain numerous important vitamins and minerals that make it nutritious. Kale can be consumed in different forms such as using it for salads, chips, smoothies, or in soups; however, eating raw kale or steamed kale offers the best results.
