3 min read

According to the Celiac Disease Foundation, a gluten-free diet requires excluding all foods containing wheat, rye, and barley. For those with celiac disease, gluten sensitivity, or other health reasons, knowing what are some gluten-free food options is the first step toward a healthier lifestyle.

Quick Summary

Naturally gluten-free whole foods, such as fresh fruits, vegetables, unprocessed meats, and legumes, form the foundation of a safe diet. Many alternative grains and starches are also available, but vigilance is required when purchasing processed products due to the risk of hidden gluten and cross-contamination. Learning how to read labels correctly is critical.

Key Points

Embrace Whole Foods: Focus on naturally gluten-free foods like fresh produce, lean proteins, and plain dairy to build a healthy diet.
Explore Alternative Grains: Include nutrient-dense grains such as quinoa, brown rice, buckwheat, and certified gluten-free oats for variety and fiber.
Master Label Reading: Always look for a 'gluten-free' certification and check allergen statements and ingredient lists for sources of gluten.
Prevent Cross-Contamination: Use separate equipment and cooking surfaces at home and be cautious when dining out to avoid accidental gluten exposure.
Use Baking Alternatives: Substitute wheat flour with blends of alternative flours and starches, such as almond, rice, and tapioca, to create delicious baked goods.
Dining Out Requires Research: Call restaurants during off-peak hours and ask specific questions about their gluten-free preparation methods to ensure safety.
Be Aware of Hidden Gluten: Many processed foods, sauces, condiments, and flavorings can contain hidden gluten, so always double-check.

Building Your Plate with Naturally Gluten-Free Foods

The easiest way to follow a gluten-free diet is to focus on fresh, unprocessed foods. These items are naturally free from gluten and provide essential nutrients.

Fruits and Vegetables

All fresh fruits and vegetables are naturally gluten-free. Be cautious of processed varieties that may have added sauces or flavorings containing gluten. Safe options include most fresh varieties like apples, bananas, broccoli, and spinach.

Meats, Poultry, and Fish

Plain, unprocessed meats, poultry, and fish are naturally gluten-free. Processed products, marinades, or breading can contain gluten, so check labels carefully on items like hot dogs or deli meats. Fresh options like beef, chicken, turkey, salmon, and cod are safe.

Legumes, Nuts, and Seeds

Naturally gluten-free, beans, lentils, peas, nuts, and seeds are good sources of protein and fiber. Watch out for cross-contamination in bulk bins and check labels on processed varieties. Safe options include black beans, chickpeas, quinoa, almonds, and chia seeds.

Dairy Products

Plain dairy products like milk, butter, yogurt, and cheese are generally gluten-free. Avoid flavored or processed dairy items that might contain gluten additives.

Exploring Gluten-Free Grains and Starches

A gluten-free diet can still include a variety of grains and starches.

Rice: All types, including brown, white, and wild, are naturally gluten-free.
Quinoa: This seed is a complete protein and naturally gluten-free.
Certified Gluten-Free Oats: Choose oats specifically certified gluten-free to avoid cross-contamination during processing.
Corn: Cornmeal, polenta, and grits are safe, but check for gluten additives.
Other Grains: Sorghum, millet, buckwheat, teff, and amaranth are naturally gluten-free options.

Mastering the Art of Gluten-Free Baking and Cooking

Gluten-free baking often uses a blend of alternative flours and starches.

Flour Alternatives: Almond, coconut, brown rice, chickpea, and buckwheat flours are popular substitutes.
Starches and Binders: Cornstarch, tapioca starch, and arrowroot starch are used for thickening. Xanthan gum helps provide structure.

Decoding Food Labels and Preventing Cross-Contamination

Careful label reading is essential. The FDA standard for 'gluten-free' is less than 20 ppm. Look for a 'gluten-free' label, check allergen statements for 'Wheat', and scan the ingredients list for sources of gluten. Remember, 'wheat-free' does not guarantee gluten-free.

Cross-contamination occurs when gluten-free food contacts gluten. Use separate kitchen equipment and storage for gluten-free items. Be cautious of shared fryers in restaurants.

Conclusion

Adopting a gluten-free diet is manageable with the right information. Focus on naturally gluten-free whole foods and learn to identify hidden gluten in processed items and during food preparation.

Frequently Asked Questions

A 'wheat-free' product may not be gluten-free, as it could still contain other gluten-containing grains like barley or rye. A 'gluten-free' label ensures the product meets the FDA standard of containing less than 20 parts per million of gluten.

Oats are naturally gluten-free, but they are often processed in facilities that also handle wheat, barley, and rye. This can lead to cross-contamination. To ensure safety, always purchase oats that are specifically certified as gluten-free.

To prevent cross-contamination, use separate toasters, cutting boards, and cooking utensils for gluten-free food. Store gluten-free products in separate, clearly labeled containers, and clean surfaces thoroughly before preparing gluten-free meals.

Fried foods are often prepared in a shared deep fryer with breaded items, leading to cross-contamination. Unless a restaurant has a dedicated gluten-free fryer and cooking space, it is safest to avoid fried foods.

Tamari and coconut aminos are excellent gluten-free alternatives to traditional soy sauce. Always check the label to confirm they are certified gluten-free, as some brands may contain wheat.

Instead of wheat flour, you can use cornstarch, arrowroot starch, or potato starch as effective thickeners for gravies, sauces, and soups.

While fresh, unprocessed meats are safe, processed deli meats can sometimes contain gluten as a binder or filler. Ask for clarification and ensure the slicer is cleaned and gloves are changed to prevent cross-contamination.
