A gluten-free diet is the primary nutrition therapy for which digestive system condition?

• A. Celiac disease
• B. Lactose intolerance

• D. Crohn disease

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the role of a gluten-free diet. A gluten-free diet eliminates gluten, a protein found in wheat, barley, and rye, which can trigger immune responses in certain digestive conditions.
2. Step 2: Identify the digestive system condition that specifically involves an immune reaction to gluten. This condition damages the lining of the small intestine when gluten is consumed.
3. Step 3: Review the options: Lactose intolerance involves difficulty digesting lactose, GERD is related to acid reflux, and Crohn disease is an inflammatory bowel disease not specifically triggered by gluten.
4. Step 4: Recognize that Celiac disease is the condition where a gluten-free diet is the primary nutrition therapy because it directly involves gluten sensitivity causing intestinal damage.
5. Step 5: Conclude that among the given options, Celiac disease is the digestive system condition treated primarily with a gluten-free diet.
