Kale is that dark, curly, hearty looking green that you pass by in the supermarket. As you pass it you glance at it and maybe you even spare it a thought thinking that it’s green so it must be good for me, perhaps I should get some, but what would I do with it, it looks daunting and besides it is green and healthy so it probably tastes pretty bad. Hmm not today and you walk swiftly on to the carrots. Carrots are easy, I know what to do with carrots and apparently they are good for my eyes.
