I will admit, very readily, that when I heard about the “gluten free” diet a few years ago, I thought it was a trend or just another weird excuse for an eating disorder. Gluten is a protein found in wheat, barley, rye and their cousins. Gluten intolerance makes drinking regular beer or eating soy sauce impossible. For the gluten intolerant, eating regular bread or pizza or pasta is simply not in the plan. The horror.
