Celiac disease (CD) is an autoimmune condition triggered by permanent sensitivity to gluten in genetically predisposed individuals. It can occur in any age group, with a significant prevalence worldwide, affecting approximately 2 million people in Brazil, although the majority remain undiagnosed. Inflammation of intestinal cells due to the presence of gliadin, a protein found in wheat, oats, rye and barley, leads to deterioration of the small intestine mucosa, resulting in symptoms such as diarrhea, bloating and pain. Complete exclusion of gluten from the diet is essential to prevent complications, however, this represents a significant challenge due to the ubiquity of gluten in many food products.
