There is a lot of new research that is saying that gluten is a major problem with things such as the increase of Alzheimer's, Diabetes, etc. I struggled with that as the word of wisdom says wheat is for man... but I have personally decided, that the wheat we have today is not the same wheat we had back when that revelation was given. Wheat has changed greatly, perhaps in conflict to what our bodies are able to properly process (think about it, if they bioengineer a crop to be resistant to pests, could that not also make our ability to process it more difficult?)... I like the two books mentioned in the subject... seem to be based on solid research. The guy that wrote grain brain in particular is considered one of the leading doctors in his field and has had great success with patients by eliminating gluten from their diet.
