Bok Choy Nutrition Facts

A member of the brassica family, bok choy offers nutritional assets similar to those of other cabbages: It is rich in vitamin C and contains significant amounts of nitrogen compounds known as indoles, phytochemicals that are believed to deactivate potent estrogens that can stimulate the growth of tumors, particularly in the breast.

Bok choy is also rich in fiber, potassium, and calcium. A cup of bok choy has roughly the same amount of calcium as ½ cup of milk.

Bok choy is also a good source of folate (vitamin B9). And with its deep green leaves, bok choy has more beta-carotene than other cabbages. A cup of bok choy contains nearly the entire RDA for beta-carotene.

Bok choy is by far the healthiest type of cabbage you can eat, says Dr. Barry Sears in his book The Top 100 Zone Foods.
