I was taking a friend's word on how amazingly beneficial wheatgrass juice is, until he claimed I could get everything I needed from wheatgrass indefinitely, which seemed outright crazy. So I researched it myself and I didn't find compelling evidence it's any more beneficial than normal vegetables. I have some in my freezer so I'm going to use it but unless you have a cheap source I don't think it's worth it, given that it tends to be expensive and taste like lawn clippings. This is embarassing.
