If you don’t have celiac disease or gluten sensitivity, think twice before ditching gluten: being gluten-free doesn’t automatically make a product better for you.

Some gluten-free breads have up to 13 times more fat and 16 times more protein than others, according to a recent study that compared 11 different gluten-free breads.
