Bakeries are now offering many gluten-free options to meet the rising demand from those following a gluten-free diet. Gluten is a protein found in grains like wheat, rye, and barley that provides elasticity and texture to foods. For those with celiac disease, gluten can cause digestive issues, so they must avoid it by following a gluten-free lifestyle. While this used to be difficult due to limited options, many bakeries now provide high-quality gluten-free pastries and treats to satisfy those needing gluten-free diets or lifestyles. Duet Bakery Boutique in Brooklyn is recommended for its excellent gluten-free pastries made by Chef Diana Rodov.
