What dietary change should be implemented for a patient diagnosed with celiac disease?

For a patient diagnosed with celiac disease, the most important dietary change is the avoidance of gluten-containing grains, specifically wheat, barley, and oats. This is because celiac disease is an autoimmune disorder wherein the ingestion of gluten leads to intestinal inflammation and damage. Even small amounts of gluten can trigger symptoms and result in long-term complications, such as malabsorption, nutrient deficiencies, and increased risk of other autoimmune conditions.

By eliminating these grains, patients can mitigate the adverse effects of the disease, allowing the intestinal lining to heal and improving overall health. It is crucial for individuals with celiac disease to read food labels carefully and be aware of cross-contamination, as gluten can be present in unexpected products due to processing methods.

The other options do not directly address the necessity of avoiding gluten, which is central to managing celiac disease effectively. Increased fiber intake could be beneficial in general but is not specifically tailored to the needs of someone with celiac disease, particularly if it involves gluten-containing sources. Incorporating more dairy may not be appropriate, as many individuals with celiac disease may also develop lactose intolerance following damage to the intestinal lining. Introducing gluten-containing supplements is counterproductive and directly counters the management of the disease, as the goal is to completely avoid
