I've heard of people growing kale and eating kale burgers as an alternative to fat-filled hamburgers.
I haven't tried kale burgers yet, but I've tossed kale into my salads. The flavor is not too strong, and Tim and Scott didn't complain when I added it to the salads. However when I added it to a smoothie, they weren't interested. The flavor didn't detract from the fruit in the smoothie, but my blender didn't get it smooth enough. There were a few crunchy places, but a better blender might solve that problem.
Kale is super rich in vitamin K, so if you're on blood thinners you want to avoid it.
Kale is also a good source of copper, potassium, iron, manganese and phosphorus. There are only thirty-three calories per cup. It also contains large amounts of vitamins A and C. It's a good source of antioxidants with many anti-cancer health benefits.
Kale is also high in fiber and helps lower cholesterol and reduce the risk of heart disease. Cooked kale is supposed to be better than raw according to some studies, but so far I've not tried it cooked. Most of the research I've read suggests cutting kale into half inch segments and steaming is best way to eat for the most nutrient impact.
What about you? Have you tried kale? How do you like it?
