According to a kidney doctor my father spoke too, not only is creatine deadly and possibly worse than crystal meth, eating too much steak can destroy your kidneys. When I prompted this doctor to prove this is the case in healthy weight lifting young men with no prior kidney issues, he obviously could not give any scientific proof to his statements. What I don't understand is why hasn't this scientific fact been established through scientific research and study? I know this was covered in Dr. Lowery's article a few weeks back http://www.T-Nation.com/free_online_article/sports_body_training_performance_nutrition/inconvenient_truths_protein_health_and_strength_sports and I'm sure this has been beaten to death on these boards but I needed a place to vent.
In the spirit of this post and because I'm sure there are other non-sensical gems people have heard out there, what's the most absurd nutritional "advice" people have gotten out there?
