βKey Takeaways
The Condiment Trap
You spent 20 minutes reading the label on your main dish. Then you squeezed on some sauce without a second thought. That sauce just glutened you.
Condiments and sauces are one of the top sources of accidental gluten exposure. Many contain wheat flour as a thickener, malt vinegar, soy sauce (which contains wheat), or barley-based ingredients.
Sauces: Safe vs. Unsafe
Soy Sauce β β CONTAINS GLUTEN
Traditional soy sauce is roughly 50% wheat. This is the #1 condiment mistake celiacs make.
Safe alternatives:
BBQ Sauce β β οΈ CHECK EVERY BRAND
Many BBQ sauces use malt vinegar or wheat-based thickeners.
Ketchup β β USUALLY SAFE
Most ketchup is gluten-free. Heinz, Hunt's, and store brands are typically safe.
β οΈ Exception: Some specialty/artisan ketchups include malt vinegar.
Mustard β β USUALLY SAFE
Plain yellow mustard (French's, Heinz) is GF. Watch out for:
Mayonnaise β β USUALLY SAFE
Hellmann's, Duke's, and most major brands are GF. The base ingredients (eggs, oil, vinegar) are naturally GF.
Salad Dressings β β οΈ HIGH RISK
This is where most people get caught.
Safe brands: Primal Kitchen, Tessemae's, Annie's (check label)
Worcestershire Sauce β β οΈ CHECK
Lea & Perrins original contains malt vinegar (barley). Some people react, others don't. The gluten content is debated, but strict celiacs should avoid it.
Safe alternative: Wizard's Gluten-Free Worcestershire
Hot Sauce β β ALMOST ALWAYS SAFE
Tabasco, Frank's RedHot, Cholula, and Sriracha are all GF. Hot sauce is usually just peppers, vinegar, and salt.
Teriyaki Sauce β β CONTAINS GLUTEN
Traditional teriyaki = soy sauce + sugar. Almost always contains wheat.
Safe alternative: San-J Gluten-Free Teriyaki
Gravy β β ALMOST ALWAYS CONTAINS GLUTEN
Traditional gravy uses wheat flour as a thickener. Make homemade with cornstarch or use Pacific Foods GF Gravy.
Pasta Sauce β β USUALLY SAFE
Most tomato-based pasta sauces are GF (Rao's, Prego, Barilla). Check cream-based and pesto sauces.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten β a protein found in wheat, barley, and rye β triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Gluten-free certification
- Gluten-free certification, such as the GFCO (Gluten-Free Certification Organization) seal, verifies that a product contains fewer than 10 parts per million (ppm) of gluten β stricter than the FDA's 20 ppm threshold for "gluten-free" labeling.
- Malt (Barley)
- Malt is fermented barley used as a flavoring or sweetener in cereals, chocolates, and beer; it is a major source of hidden gluten that is often overlooked on ingredient lists.
