I love bok choy but don't eat enough of it. I also think it contains the most calcium of any food? I read that somewhere but the little snippet doesn't say that.
Did you know that cabbage, like bok choy, is great for losing weight? One cup of raw bok choy contains only 22 calories while supplying you with a wealth of health-promoting nutrients. Like its other cruciferous cousins, broccoli, kale and mustard greens, cabbage is not only an excellent source of vitamin C and dietary fiber, but also contains many unique sulfur-containing phytonutrients, such as indole-3-carbinole (I3C) and sulforaphane. I3C and sulforaphane help activate and stabilize the body's antioxidant and detoxification mechanisms. Other sulfur compounds, which are produced as a result of cutting, chewing or digesting cabbage, increase the liver's ability to produce enzymes that neutralize potentially toxic substances. Cabbage is easily available, inexpensive, and easy to prepare. Try our tasty recipes and you'll see why cabbage is a dietary staple of long standing throughout the world.
