Kale is popular now, but people have been growing this super food for more than 2,000 years. Popular in Europe during Roman times and the Middle Ages, it arrived in the U.S. in the 17th century.
Kale is packed with antioxidants and other nutrients. Some research suggests that regularly eating vegetables in the cabbage family, like kale, helps lower the risk of certain cancers. Of course, many other things also affect your cancer risk.
One cup of chopped raw kale provides more than 100% of the recommended daily amount of vitamins A and K.
