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.

    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.
