Gluten-free products aren’t just for purely allergic or dietary reasons anymore. The gluten-free trend is being boosted by fad diet enthusiasts as a way to eat better and lose weight. According to Datamonitor, global sales of gluten-free products are expected to grow to $4.3 billion by 2015. Is your restaurant offering gluten-free dishes? A new survey from Smart Brief shows the majority of restaurants are including gluten-free items on their menus. Some even have separate gluten-free menus, and even those that don’t list gluten-free items will often create gluten-free meals upon request.
