Of course we will never know if the injury would have happened with a stellar diet BUT I do see a LOT of teenagers chasing to be "vegetarian"... but actually become "carbeterians"... and are suffering because of it: add/adhd, autoimmune diseases like psoriasis, hashimotos, ITP, chronic fatigue syndrome, etc. You can't expect to throw a hornets next like a gardasil shot at a kid taking in ZERO nutrients and ZERO antioxidants and expect them to do well. It just won't happen.
