Benefits of growing and eating kale

Kale: almost a miracle plant. I live with osteoarthritis and have been slowly finding out what triggers inflammation. Beef and some animal products so far seems to be the culprits. I'm not saying no one should eat beef, but for me, it seems to be a problem.
Browsing some medical journals that deal with diet, I discovered some evidence that the curly plant, kale, can replace beef easily in one's diet. No, it'll probably never taste like it but it has nutrients beyond. For example, it has more iron than beef, more calcium than milk, fiber, and a nice balance of the omega fatty acids. It grows to maturity in 55 - 60 days. I love it swiftly sauteed in extra virgin olive oil, in a tortellini soup, chopped in salad. Cut the leaves when they are the size of your hand or smaller. Cut around the rib, then chop for either a fresh salad or to put in soup. Here's my friend Ivy's tortellini soup. I love it because of all the vegetables in it.
