Gluten is a protein found in wheat, barley and rye. It’s used in baked goods, like bread, cake and pasta. In the United States, it’s also found in other products like cereals and snack foods.
Some people think of gluten as something they need to avoid when eating out. But, it doesn’t always have to be a no-go for everyone. In fact, the gluten-free diet has become extremely popular as more research is done on the benefits of avoiding it.
