Kale Wards Off Depression

A Columbia University psychiatrist is a great supporter of kale and explains that people love kale so much because its nutrients help make them feel optimistic and keep depression away. One of the reasons of why kale helps with mood is because of its phytonutrients. They generate carotenoids and as per the recent studies at Harvard University, carotenoids are associated to uplifting of mood.

Kale is also loaded with omega-3 fatty acids which can be extremely helpful in fighting the depression symptoms.
The blend of iron, protein, vitamin B6 and folate found in kale can produce more dopamine and serotonin. These two compounds interact in the brain and help elevate mood.

Kale and Diabetes

Diabetes occurs when the body is unable to produce adequate insulin because of which glucose level in blood shoots up.

Kale is Packed with Vitamin C

If a person is experiencing bleeding gums, fatigue or muscle pain, the person is not getting enough vitamin C. Vitamin C deficiency results in many other disorders too. Vitamin C or ascorbic acid is a powerful antioxidant and its benefits in common cold are well-known. Kale is loaded with vitamin C and provides vitamin C in more amount than oranges.

134% of the daily recommended dosage of vitamin C can be obtained from a cup of kale while an average-sized orange contains only 113%, despite the fact that a standard orange weighs 131gm and a cup of kale weighs only 67gm. This means kale has twice more vitamin C than that in an orange.

Potassium is also beneficial in preventing stroke.
20% of individuals who consume potassium in high quantities live longer. Only 1 cup of kale contains 349mg of potassium.

Being loaded with nutrients, kale is one of the best prenatal foods. Its nutrients maintain mother’s health as well as help in delivering a healthy child.

The following three types of kale should be regularly taken by an expecting mother.

Lacinato: Lacinato kale is also known as dinosaur kale because it is solid and scaly in texture. Its color is dark blue-green and flavor is stronger than curly kale. Its leaves are usually flat and longer and remain so even after cooking. It can be sautéed in salads and made into kale chips.

Red Russian: Red Russian kale has thinner and flat leaves resembling oak leaves that have a bit of purple stalks and red tinge. These stalks are not usually consumed due to their hard texture. However, leaves are delicious when added to sandwiches, soups, juices or salads or even for garnishing.

Kale Lowers Cholesterol

Due to the high fiber content of kale, it’s great for
cleansing and detoxifying the body and also helping reduce cholesterol. It collects excess cholesterol compounds from your gut and pushes them out in the excretion process.
While kale can lower cholesterol in both forms – raw and cooked, according to a new study, it offers the highest benefit when steamed because the fiber content in steamed kale attaches better to bile in the digestive tract and removes cholesterol in more amount and more effectively.

Kale for Bone Health

Because of its high calcium content, kale is good for bone health too. So also, it’s rich in vitamin K which reduces the risk of fracture, improves calcium absorption and decreases urinary excretion of calcium.

Sulfur found in kale detoxifies skin, reduces scars and produces collagen. Beta-carotene, a carotenoid occurring in high quantities in kale is converted to vitamin A by the body as required.

Another vitamin essential for skin health is vitamin C. There is 53.3 mg of vitamin C in a cup of cooked kale and this is required for building and maintaining collagen, the protein that keeps skin healthy and youthful, and also helps in wound healing. Vitamin C also helps in iron absorption.

Kale is packed with vitamin C as well as iron and thus prevents hair loss occurring due to iron deficiency.

Kale for the Protection of DNA

A study has shown that vitamin C or ascorbic acid exerts the activity of preventing IMA-induced DNA damage. Furthermore, the increased concentrations of hepatic lutein due to kale can also be associated to protection against DNA damage. However, this connection is only at a hypothetical level and is yet to be demonstrated.

Precautions

Despite the fact that kale offers numerous health benefits, it should not be consumed in excess. Consuming large amounts of leafy greens can result in gas, constipation and bloating as per one study.

Also, those who are on blood thinners should eat kale carefully because kale contains vitamin K that promotes blood clotting.

Kale also consists of oxalates, compounds that are sometimes associated to kidney stones and gallstones. To reduce the potential problems caused by oxalates, it’s recommended to chew kale well and take rest between meals.
