Nutrition assessment in celiac disease.

The gluten-free diet is currently the only treatment for celiac disease, and patients should be monitored closely by a dietitian who is knowledgeable regarding this diet. Evaluation by a dietitian includes a comprehensive assessment of dietary history, with an emphasis on caloric and micronutrient intake. Patient knowledge of the gluten-free diet is assessed and interpretation of food labels is taught. Identification of micronutrient deficiencies or comorbid gastrointestinal conditions may occur during a comprehensive dietary assessment. In patients with evidence of gluten exposure, a thorough evaluation for cross-contamination is performed.
