For anyone adhering to a gluten-free diet, the journey often involves more than just avoiding bread and pasta; it requires a detective-like approach to reading every food label. Sauces and condiments are a prime example of where gluten can hide in unexpected forms. From thickeners to flavorings, a wide array of popular sauces contain gluten, making them unsafe for those with celiac disease or gluten sensitivity.
Common Offenders: Sauces That Often Contain Gluten
Certain sauces are almost always off-limits unless specifically marked and certified as gluten-free. Understanding the typical ingredients in these products is the first step toward a safer diet.
Asian Sauces
Traditional soy sauce is made with wheat and soybeans, so it is not gluten-free. Because soy sauce is a base for many other Asian condiments, several are also contaminated with gluten.
- Soy Sauce: The primary ingredient is wheat unless labeled as Tamari or a gluten-free alternative.
- Teriyaki Sauce: Most commercial teriyaki sauces are made with regular, wheat-containing soy sauce.
- Hoisin Sauce: Often contains wheat starch or soy sauce as an ingredient.
- Oyster Sauce: Traditional versions may contain soy sauce or wheat starch.
Gravies and Cream Sauces
Many gravies and cream-based sauces use a 'roux' for thickening, which is a combination of fat and wheat flour. This is common in both packaged mixes and restaurant versions.
- Gravy: Powdered mixes and pre-made gravies often rely on wheat flour as a thickener.
- Alfredo Sauce: While a basic recipe might be gluten-free, many jarred versions use a wheat flour thickener for a smoother consistency.
- Brown Sauces: Products like HP Brown sauce contain gluten and should be avoided.
Marinades and Vinaigrettes
Gluten can appear in marinades and salad dressings via specific ingredients used for flavor or texture.
- Worcestershire Sauce: The traditional and many common versions contain malt vinegar, which is derived from barley and is not gluten-free.
- BBQ Sauce: Some brands use wheat-based thickeners, modified food starch, or add soy sauce for flavor.
- Salad Dressings: Some creamy dressings or those with specific flavorings may contain malt vinegar, soy sauce, or wheat flour.
Decoding the Label: Ingredients to Watch For
Becoming a savvy label reader is essential. While the FDA requires wheat to be listed as an allergen, other gluten-containing ingredients may not be as obvious.
- Malt: Found as malt flavoring, malt vinegar, or malt extract, this ingredient is derived from barley and is a key source of gluten in many products.
- Modified Food Starch: While it can be derived from safe sources like corn, if the source is not specified as 'corn' or 'potato', it could be wheat-based.
- Wheat Flour: A common and direct source of gluten used in many sauces as a thickener.
- Brewer's Yeast: A byproduct of beer brewing, which is not gluten-free.
- Natural Flavors: This can be a catch-all term. While a manufacturer must declare wheat as an allergen, if the flavor is derived from barley or rye, it may not be explicitly named.
Comparison Table: Common Sauces and Their Gluten Status
| Sauce Type | Typically Gluten-Containing | Safe Gluten-Free Alternatives |
|---|---|---|
| Soy Sauce | Traditional soy sauce | Certified gluten-free soy sauce or Tamari |
| Teriyaki Sauce | Most bottled varieties | Homemade teriyaki with Tamari or certified GF versions |
| Worcestershire | Original versions with malt vinegar | Brands that use white vinegar or are certified GF |
| BBQ Sauce | Many standard brands | Certified gluten-free BBQ sauces (e.g., Stubb's) |
| Gravy | Standard powdered mixes and restaurant gravies | Bisto Gluten-Free Gravy Granules or cornstarch-thickened gravies |

Tips for Successfully Navigating Gluten-Free Sauces
- Look for Certification: The most reliable way to ensure a sauce is gluten-free is to look for a certified gluten-free label on the packaging. These products have been tested to contain less than 20 parts per million of gluten, the standard set by the FDA.
- Contact Manufacturers: If a sauce doesn't have a certification label, contact the manufacturer directly to inquire about their ingredients and production processes. This is especially important for products with vague ingredient listings.
- Opt for Homemade: By making sauces from scratch, you have complete control over every ingredient. You can use cornstarch or tapioca flour instead of wheat flour for thickening and use gluten-free versions of key ingredients like soy sauce.
- Practice Kitchen Hygiene: When preparing gluten-free food, avoid cross-contamination. Use separate utensils, cutting boards, and cookware to prevent any contact with gluten-containing products.
Conclusion: Vigilance is Key to a Safe Gluten-Free Diet
For individuals with celiac disease or gluten sensitivity, understanding what sauces are not gluten-free is not just a preference but a necessity for health and well-being. Hidden sources of gluten are common in many sauces and condiments due to ingredients like wheat, barley (malt), and wheat-based thickeners. By diligently reading labels, choosing certified gluten-free products, and making sauces at home, you can confidently enjoy a flavorful and safe diet. For further information and resources on gluten-free living, refer to authoritative sources like the Celiac Disease Foundation.
