Antioxidants – May Help Reduce Inflammation
In addition to these essential nutrients, bok choy also contains antioxidants like beta-carotene and lutein, which help to protect the body against cellular damage and inflammation.

Studies have shown that adequate intake of vitamin K is associated with reduced risk of osteoporosis and fractures in older adults.
May Reduce Risk of Some Forms of Cancer
Bok choy contains several compounds that studies have indicated may have anti-cancer properties, including glucosinolates, flavonoids, and carotenoids.

Fiber Supports Healthy Digestion
Bok choy is high in fiber, which can support healthy digestion and promote regular bowel movements. Fiber also helps to reduce the risk of constipation, colon cancer, hemorrhoids, and diverticulitis.
