Bok choy is a member of the cruciferous family of vegetables, so it’s related to broccoli, Brussels sprouts, arugula, cauliflower, cabbage, and kale. It’s most commonly found in Asian foods, but you can serve it as a side with any meal.
Since it’s a cruciferous vegetable, you can be sure bok choy is loaded with good nutrition. In fact, one cup of raw shredded bok choy has only nine calories. One cup of cooked bok choy has only 20 calories, so this is a great veggie to add to a weight loss diet.
