I found this very informative to my own research into the nutrients and value to our bodies of both spinach and kale. I have a home freezedrier :) and have so far freezedried spinach, with kale being on my short list to do next. I will be posting pictures of the freezedried spinach later today on my next post :) With the freezedried spinach it can be turned into a powder for smoothies, soups, casseroles, and to have on hand when you can't find it in season at the market. That will be the same for Kale as well.
