Final answer:
A gluten-free diet for those with celiac disease involves completely avoiding foods containing gluten, as it causes harmful autoimmune reactions and damages the small intestine.
Step-by-step explanation:
A "gluten-free diet as required" for a client with celiac disease means strictly avoiding all foods that contain gluten, which is a protein found in wheat, barley, rye, and certain other grains.
For people with celiac disease, eating gluten triggers an autoimmune response that causes damage to the microvilli of the small intestine, leading to malabsorption, nutrient deficiencies, and a range of symptoms from digestive issues to anemia and bone pain.
Complete avoidance of gluten can help manage the disease by allowing the intestine to heal, thereby improving symptoms and decreasing the risk of long-term complications such as osteoporosis, neurological issues, and certain types of cancer.
