Why is it important for individuals with celiac disease to monitor their gluten intake?

Individuals with celiac disease must monitor their gluten intake primarily to prevent deterioration of their intestinal villi. Celiac disease is an autoimmune disorder in which the ingestion of gluten—found in wheat, barley, and rye—triggers an immune response that damages the lining of the small intestine. This damage specifically impacts the intestinal villi, which are small finger-like projections that aid in nutrient absorption. When these villi become damaged or flattened due to gluten exposure, it leads to malabsorption of essential nutrients, resulting in a range of health problems, including nutritional deficiencies, digestive issues, and other systemic complications.

Maintaining a strict gluten-free diet is crucial for individuals with celiac disease, as it allows the intestinal villi to heal and function correctly, thereby restoring effective nutrient absorption and overall gut health. The other choices, while they may describe some benefits of a balanced diet or overall health improvements, do not address the specific and critical need to prevent intestinal villi damage in those with celiac disease.
