I've heard mixed reviews. The latest I've read was that it's not as bad as was first thought. I generally give my bun some everyday too, but because I've read that you should feed it sparingly, I only give about a third of a leaf in his salad. Some days he eats it and some days he doesn't. I do change his salad up from week to week though with different greens. He normally always gets organic spring greens, with a couple of other types. This week it's Romaine lettuce and cilantro with the spring greens. Next week I'll probably go back to the kale.
