Final answer:
The correct answer is b) "I should avoid all foods that contain gluten," which accurately reflects the necessary dietary restrictions for managing celiac disease. Consuming even small amounts of gluten can damage the small intestine in individuals with celiac disease, necessitating a strict gluten-free diet.
Step-by-step explanation:
The correct statement, which indicates an understanding of the teaching for an adolescent with a new diagnosis of celiac disease, is: b) "I should avoid all foods that contain gluten." This reflects an accurate understanding of the dietary restrictions required to manage celiac disease. When a person with celiac disease consumes gluten, a protein found in wheat, barley, and rye, it triggers an autoimmune reaction that damages the lining of the small intestine. This damage affects the microvilli, leading to various symptoms such as digestive distress, malnutrition, and other complications.
Eating foods that contain gluten even in small quantities can cause significant harm to individuals with celiac disease, therefore, adherence to a gluten-free diet is crucial. Other statements such as consuming gluten in moderation, avoiding only wheat-based products, or suggesting gluten would not affect the digestive system are incorrect and reflect a dangerous misunderstanding of the condition.
