Bok choy, pak choi or Chinese white cabbage, belongs to the cruciferous family of vegetables. It was first cultivated in China thousands of years ago. Now it is available all over the world.
Folate and vitamin B-6 remove the amino acid homocysteine from the blood. This is important because high levels of homocysteine increase the risk of cardiovascular disease. You’ll gain 11 percent of the recommended daily intake of both folate and vitamin B-6 by eating 1 cup of shredded bok choy. It also has 4 percent of the daily value of potassium, which regulates the heartbeat. The calcium and magnesium essential for bones also play a role in maintaining a healthy heart. Calcium stimulates heart muscles to contract, while magnesium encourages them to relax.
One cup of shredded bok choy has 34 percent of the recommended daily value of vitamin C and more than a full day’s intake of vitamin A. Vitamin C works as an antioxidant in the body, protecting cells from damage by neutralizing free radicals, or unstable molecules that result from vital chemical processes. Vitamin A is a broad term that refers to a group of related substances.
