How to Avoid Cross-Contamination
For those with celiac disease, preventing cross-contamination is critical. Follow these tips:
- Separate surfaces: Use dedicated cutting boards, cookware, and utensils for gluten-free cooking.
- Separate appliances: Have a separate toaster or use toaster bags to prevent crumbs.
- Clean thoroughly: Wash all cooking surfaces, utensils, and hands with hot, soapy water.
- Separate storage: Store gluten-free foods in sealed, labeled containers on separate shelves.
- Label clearly: Ensure all gluten-free items are clearly marked.
Nutritional Considerations for a Gluten-Free Diet
A gluten-free diet can sometimes lead to deficiencies if not well-planned.
- Fiber: Many gluten-free replacement products are low in fiber. Increase fiber intake by focusing on whole, gluten-free grains like quinoa and amaranth, as well as fruits, vegetables, and legumes.
- Vitamins and Minerals: Fortified wheat products are often a source of B vitamins and iron. Opt for naturally nutrient-rich foods and consider fortified gluten-free products to get sufficient iron, folate, and B vitamins. A registered dietitian can help identify potential deficiencies and recommend supplements.
- Healthy Fats: Gluten-free packaged foods can be higher in fats and sugars. Focus on healthy, naturally gluten-free fat sources like avocado, nuts, and olive oil.
