Gluten forms in bread dough when proteins from the grain cross-link. Although this process is key to the texture and rising in bread, some people cannot digest gluten. Gluten-free breads let them enjoy a loaf just like other people do.

According to the U.S. Department of Agriculture, which is responsible for reporting nutrition facts on various foods, a typical serving of gluten-free bread is a single slice.

One serving of gluten-free bread contains about 110 calories. Of these calories, 18 come from fat.

The 18 fat calories in gluten-free bread consist of 2 g of total fat. None of these fats are unhealthy saturated fats. Rather, they are unsaturated fats, the kind that "You: The Owner's Manual" author Dr. Mehmet Oz describes as producing heart-healthy HDL cholesterol.
