The nutrients in bok choy may offer protection from a number of conditions.
Protection from cancer
Bok choy is a cruciferous vegetable that can provide valuable nutrients.
Bok choy and other cruciferous vegetables have certain anti-cancer properties.
Studies have shown that some people who eat more cruciferous vegetables have a lower risk of developing lung, prostate, and colon cancer.
Bok choy contains folate. Folate plays a role in the production and repair of DNA, so it might prevent cancer cells from forming due to mutations in the DNA.
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 helps to detoxify some cancer-causing compounds in the body. Selenium also prevents inflammation and decreases tumor growth rates.
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 also feed healthy gut bacteria, which affects overall health, metabolism, and digestion.
The iron, phosphorous, calcium, magnesium, zinc, and vitamin K in bok choy all contribute tobuilding 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.
