Bok choy can be a nutritious addition to a balanced diet. Health benefits may include reducing the risk of health issues, such as heart disease, diabetes, and cancer.
Bok choy, pak choi or Chinese white cabbage, belongs to the cruciferous family of vegetables. First cultivated in China thousands of years ago, bok choy is now available all over the world. Other cruciferous vegetables include kale, broccoli, cauliflower, Brussels sprouts, cabbage, collard greens, rutabaga, and turnips.
These vegetables are a good supply of nutrients and are low in calories. They are well suited to a healthful diet.
The nutrients in bok choy may offer protection from a number of conditions.
Protection from cancer

Bok choy and other cruciferous vegetables have certain anti-cancer properties.
Bok choy contains folate. Folate
Bok choy also contains vitamin C, vitamin E, and beta-carotene. These nutrients have powerful antioxidant properties that help protect cells against damage by free radicals.
Unlike most other fruits and vegetables, bok choy contains the mineral selenium.
Selenium
Cruciferous and other vegetables also offer protection because they provide fiber. Fiber keeps the stool moving. This keeps the bowel healthy and reduces the risk of developing colorectal cancer.
Fibrous foods
Bone health
The iron, phosphorous, calcium, magnesium, zinc, and vitamin K in bok choy all contribute to building and maintaining bone structure and strength.
Iron and zinc play crucial roles in the production and growth of collagen.
Phosphorus and calcium are both important in bone structure. However, proper bone growth needs a careful balance of both these nutrients. A diet that contains too much phosphorus and not enough calcium can result in bone loss.
Vitamin K helps maintain the balance of calcium in the bones, which means it might help reduce the risk of bone fractures.
Blood pressure
Potassium, calcium, and magnesium are all present in bok choy. They can help decrease blood pressure naturally.
According to an article in the American Journal of Clinical Nutrition, people should increase their intake of potassium. Some evidence shows that consuming 4,700 mg of potassium daily decreases blood pressure caused by high sodium intake.
The same article notes that many people consume too much sodium, which increases the risk of developing high blood pressure. people should consume no more than 1500 milligrams (mg) of sodium per day.
Heart health
Bok choy’s folate, potassium, vitamin C, and vitamin B-6 content, coupled with its lack of cholesterol, all help to maintain a healthy heart.

Immunity
The selenium found in bok choy has been found to improve immune response to infection by stimulating the production of T-cells that identify and kill invading bacteria and viruses.
Skin
Collagen, the skin’s support system, relies on vitamin C. Vitamin C is an essential nutrient that has antioxidant properties that may help prevent damage caused by the sun, pollution, and smoke. Vitamin C also promotes collagen’s ability to smooth wrinkles and improve overall skin texture.

Raw bok choy, like all cruciferous vegetables, contains an enzyme called myrosinase.
Myrosinase can hinder thyroid function by preventing the body from absorbing iodine. Cooking deactivates it. Eating raw bok choy in moderate amounts does not pose a hazard.
A person who is taking blood-thinners, such as Coumadin, or warfarin, should not suddenly increase or reduce the amount of vitamin K they consume in food, as vitamin K plays a role in blood clotting.
It is essential to consider the overall diet to achieve good health and prevent disease. It is better to consume a variety of foods than to concentrate on individual items as the key to good health.
