probably not everything... This is why kale smoothies are awful. (excuse me while I duck away from the kale smoothie people that are about to insist it's "healthy".)
Also. kale is worse. IMO it's only acceptable use is garnish. You know. Like Pizza hut' (before it was a "super" food.... the largest importer of kale was Pizza Hut; for the decoration around the bowls of the salad bar fixings.)
