Ditto on the insulin issue. I feel that a lot of the information offered on training nutrition is put out by people wanting to sell stuff. No issue with that, but a clear understanding of how insulin effects the post workout anabolic "window" and long term effects (i.e. diabetes) of regular insulin spiking would be good ammunition to have. That might cover how protein powders are utilised by the body; how much is used to build muscle, how much is converted to glucose, what the effect on blood sugar and insulin of a fast acting whey product, etc.
