Gluten is the protein found in grains such as rye, barley, wheat, and triticale. Foods with gluten cause food intolerance for consumers who have celiac disease, an autoimmune and inherited dysfunction in which gluten weakens the small intestine. Experts estimate that Celiac disease affects 1% of healthy people in the United States. That imlies that least 3 million people in the United States have celiac disease, with 97% of them undiagnosed. In the United States, people consume gluten-free foods to treat people with celiac disease or people without this condition for its supposed health benefits. As per Renub Research report, the United States Gluten Free Food Market will reach USD 11.4 Billion by 2026.
