Why Label Reading Is So Hard


You'd think spotting gluten would be simple β€” just look for "wheat," right? Unfortunately, gluten hides under dozens of names that most people don't recognize.


The Obvious Gluten Sources


These are easy to spot on labels:


  • β–ΊWheat β€” (all types: durum, semolina, spelt, kamut, einkorn, farro)
  • β–ΊBarley β€” (and malt, which comes from barley)
  • β–ΊRye
  • β–ΊTriticale β€” (wheat-rye hybrid)

    The Hidden Gluten Names


    These ingredients contain or may contain gluten but aren't obviously wheat-based:


    Definitely Contains Gluten

  • β–ΊMalt extract / malt flavoring / malt vinegar
  • β–ΊBrewer's yeast
  • β–ΊWheat starch (unless labeled gluten-free)
  • β–ΊSeitan
  • β–ΊFu (a Japanese wheat gluten)
  • β–ΊCouscous

  • May Contain Gluten (Check Source)

  • β–ΊModified food starch (could be wheat-derived)
  • β–ΊDextrin (sometimes wheat-based)
  • β–ΊCaramel color (usually safe, but check)
  • β–ΊNatural flavors (occasionally contains barley malt)
  • β–ΊSoy sauce (most brands use wheat)
  • β–ΊSeasonings and spice mixes

  • FDA Labeling Rules


    The FDA requires that any product labeled "gluten-free" must contain less than 20 ppm of gluten. However:


  • β–ΊProducts without a gluten-free label may still be gluten-free
  • β–Ί"Wheat-free" does NOT mean gluten-free (barley and rye contain gluten too)
  • β–Ί"May contain wheat" warnings are voluntary β€” absence doesn't mean safety
