1. It's not a new kid on the block
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.
2. How to make kale chips
Kale chips are a simple, good-for-you snack. Remove kale leaves from stems, tear into bite-sized pieces, drizzle with olive oil and a dash of salt, and bake 10 to 15 minutes in a 400 F oven.
3. Powerhouse food
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.
4. Vitamins you get
One cup of chopped raw kale provides more than 100% of the recommended daily amount of vitamins A and K.
5. Kale's relatives
Kale belongs to the same family as cabbage, Brussels sprouts, and collards.
6. When it's best
For the best flavor, kale must be harvested after the first frost. This ensures that some of the starches have turned into sugars.
7. Colors of kale
Types of kale are marked by color (green, white, purple, or bluish green) and leaf shape.
