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 โ€” โ›” CONTAINS GLUTEN

Traditional soy sauce is roughly 50% wheat. This is the #1 condiment mistake celiacs make.


Safe alternatives:

  • โ–บTamari (wheat-free soy sauce) โ€” always verify "gluten-free" on label
  • โ–บCoconut aminos โ€” soy-free AND gluten-free

  • BBQ Sauce โ€” โš ๏ธ CHECK EVERY BRAND

    Many BBQ sauces use malt vinegar or wheat-based thickeners.

    Ketchup โ€” โœ… USUALLY SAFE

    Most ketchup is gluten-free. Heinz, Hunt's, and store brands are typically safe.


    โš ๏ธ Exception: Some specialty/artisan ketchups include malt vinegar.


    Mustard โ€” โœ… USUALLY SAFE

    Plain yellow mustard (French's, Heinz) is GF. Watch out for:

  • โ–บBeer mustard โ€” contains barley
  • โ–บDijon mustard โ€” some brands use wheat-based verjuice

  • Mayonnaise โ€” โœ… USUALLY SAFE

    Hellmann's, Duke's, and most major brands are GF. The base ingredients (eggs, oil, vinegar) are naturally GF.


    Salad Dressings โ€” โš ๏ธ HIGH RISK

    This is where most people get caught.

    Malt vinegarRanch, Italian
    Soy sauceAsian-style dressings
    Wheat flourCreamy dressings (thickener)
    Barley maltSome balsamic vinegars

    Safe brands: Primal Kitchen, Tessemae's, Annie's (check label)


    Worcestershire Sauce โ€” โš ๏ธ 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 โ€” โœ… ALMOST ALWAYS SAFE

    Tabasco, Frank's RedHot, Cholula, and Sriracha are all GF. Hot sauce is usually just peppers, vinegar, and salt.


    Teriyaki Sauce โ€” โ›” CONTAINS GLUTEN

    Traditional teriyaki = soy sauce + sugar. Almost always contains wheat.


    Safe alternative: San-J Gluten-Free Teriyaki


    Gravy โ€” โ›” ALMOST ALWAYS CONTAINS GLUTEN

    Traditional gravy uses wheat flour as a thickener. Make homemade with cornstarch or use Pacific Foods GF Gravy.


    Pasta Sauce โ€” โœ… USUALLY SAFE

    Most tomato-based pasta sauces are GF (Rao's, Prego, Barilla). Check cream-based and pesto sauces.
