Actually, a fast emerging area of research is the study of gluten (protein found in wheat) and it's effects in the human body. It's been estimated recently that 1 in 150 americans suffer anywhere from a slight to a severe reaction by injesting even small amounts of gluten-containing foods. In an interesting twist, many of the nasty diseases that are found in so many people these days are starting to show some sort of relation to gluten. No, this isn't celiac; this is something entirely different. I had a blood and stool sample taken and the results showed I have a "double copy" of a gene that is directly linked to individuals who suffer auto-immune reactions to gluten (which means both my mom and dad have the gene). How strange that it was nearly impossible to build and maintain any amount of muscle for the majority of my life; that is, until I eliminated all wheat from my diet. Muscle is pretty easy to build now even without the aid of anabolics.
