What Foods Do You Stay Away From On A Gluten-Free Diet?

According to the National Institutes of Health, a gluten-free diet is the main treatment for celiac disease. To ensure adherence and good health, understanding what foods do you stay away from on a gluten-free diet is essential, extending beyond just bread and pasta.

Quick Summary

This comprehensive guide covers grains to avoid, obvious and hidden sources of gluten in processed foods and condiments, and crucial tips for preventing cross-contamination at home and while dining out.

Key Points

• Avoid All Wheat Derivatives: Learn to spot wheat, spelt, durum, and farro, as they are a primary source of gluten and are hidden in many foods.

• Beware of Barley and Rye: Eliminate grains like barley, rye, and triticale, which are found in cereals, beer, and malted products.

• Check for Hidden Gluten: Processed foods, sauces, condiments, and even medications can contain gluten as a thickener or binder; always read labels.

• Prevent Cross-Contamination: Use separate kitchen equipment, prep areas, and condiments to avoid accidental gluten exposure, especially if sharing a kitchen.

• Focus on Naturally Gluten-Free Foods: Base your diet on whole foods like fruits, vegetables, meat, and dairy, which are naturally free of gluten.

• Read Labels Diligently: Manufacturers change ingredients, and a product that was once safe might become unsafe. Read the ingredient list every time.

• Ask Questions When Dining Out: Always ask restaurant staff about ingredients and preparation methods to ensure your meal is safe from cross-contamination.

Grains and Grain Products to Eliminate

For anyone following a gluten-free diet, the most foundational change involves eliminating all sources of wheat, rye, and barley. This requires a deep understanding of which grains contain gluten and their various forms. Beyond just the whole grains, many processed grain products are also off-limits, which can be a significant adjustment for those accustomed to a standard Western diet.

Wheat and Its Many Derivatives

Wheat is a primary source of gluten and appears in a vast number of food items. It's not just in flour but also in numerous sub-forms that can be easily missed on an ingredient list. Derivatives of wheat to strictly avoid include:

• Wheatberries
• Durum
• Emmer
• Semolina
• Spelt
• Farina
• Farro
• Graham flour
• Kamut® khorasan wheat
• Einkorn wheat

Other Gluten-Containing Grains

In addition to wheat, a gluten-free diet also means eliminating rye, barley, and triticale. Barley is found in many malt products, while triticale is a hybrid of wheat and rye. This means beverages like beer, ales, and lagers are generally off-limits unless specifically marked as gluten-free. It is important to also avoid malt extract, malt syrup, malt flavoring, and malt vinegar.

Unsuspecting Sources of Gluten

One of the biggest challenges for those new to a gluten-free diet is identifying the hidden sources of gluten in processed foods, condiments, and even non-food products. Gluten is often used as a thickener, stabilizer, or filler, and it can lurk in surprising places. Constant vigilance and label-reading are key to avoiding these sources.

Common Hidden Sources of Gluten:

• Sauces and Dressings: Traditional soy sauce, teriyaki sauce, salad dressings, and marinades often contain wheat as a primary ingredient or thickener. Look for gluten-free soy sauce (tamari) and certified dressings.
• Processed Meats: Some cold cuts, sausages, and hot dogs use gluten as a binder or filler. Pre-seasoned meats can also contain wheat-based ingredients. Always choose unseasoned, whole cuts of meat or certified gluten-free processed options.
• Snacks and Chips: While corn and potato chips are naturally gluten-free, their seasonings can sometimes contain wheat starch or malt vinegar. Check labels carefully, especially on flavored varieties.
• Soups and Broths: Many canned soups, bouillon cubes, and soup mixes use flour as a thickener. Choose varieties that are certified gluten-free or make your own from scratch.
• Beverages: Beyond beer, some flavored coffees, wine coolers, and drink mixes can contain gluten. Always read the label on any processed beverage.
• Medications and Supplements: Gluten can be used as a binding agent in capsules, pills, vitamins, and herbal supplements. Always check with your pharmacist to ensure any medication or supplement is safe.

How to Avoid Cross-Contamination

For individuals with celiac disease or high gluten sensitivity, even trace amounts of gluten can cause a reaction. Cross-contamination is a significant risk that must be managed, both at home and when dining out.

Preventing Cross-Contamination at Home

• Dedicated Equipment: Use separate cutting boards, toasters, and porous utensils (e.g., wooden spoons) for gluten-free cooking. Toasters are a high-risk area for crumbs, so a separate one or toaster bags are necessary.
• Clean Surfaces: Always clean counters and preparation areas with hot, soapy water to remove gluten particles.
• Separate Condiments: Avoid "double-dipping" in shared condiment jars (butter, mayonnaise, jam) by using separate jars or squeeze bottles for gluten-free use.
• Dedicated Oil: If deep-frying, use fresh oil or a separate fryer for gluten-free foods, as gluten can transfer from breaded items.
• Separate Storage: Store gluten-free items on separate, preferably higher, shelves to prevent flour dust or crumbs from falling onto them.

Navigating Cross-Contamination When Dining Out

• Research in Advance: Look for restaurants with dedicated gluten-free menus or those highly rated for their celiac-safe practices. Apps like 'Find Me Gluten Free' can be valuable resources.
• Communicate Clearly: Inform your server and the chef about your dietary needs, explaining that even small amounts of gluten are harmful.
• Ask About Preparation: Inquire about how food is prepared. Ask if separate fryers, grills, and cooking surfaces are used for gluten-free dishes.
• Watch for Shared Surfaces: Be wary of buffets and self-service counters where shared utensils can lead to cross-contamination.

Conclusion: Commitment to a Label-Reading Lifestyle

Staying away from gluten is more than just eliminating bread and pasta; it is about adopting a new and mindful approach to food. The gluten-free diet requires constant label-reading, awareness of hidden sources, and careful prevention of cross-contamination in both your kitchen and restaurants. By focusing on naturally gluten-free foods like fruits, vegetables, and lean proteins, and being diligent about avoiding all gluten-containing grains and processed products, you can maintain your health while enjoying a diverse and flavorful diet. For those with celiac disease, strict adherence is non-negotiable for long-term health. For others with sensitivities, the level of strictness may vary but the core principles remain the same: read labels, ask questions, and prioritize safe eating. Consult with a registered dietitian for a personalized plan to ensure all nutritional needs are met on your journey. For more information and support on navigating a gluten-free lifestyle, authoritative resources can be found on sites dedicated to celiac disease, such as the Celiac Disease Foundation.
