Definitive List Of Ingredients Containing Gluten from the

This information is excerpted from, a website dedicated to teaching gluten-sensitive individuals simple, savvy and empowering steps to get healthy.


Since gluten-free labeling is only for food and supplements, knowing at least some of the hidden gluten ingredients are helpful for spotting gluten hidden in body care products, makeup, pet care products, and more. Small exposures perpetuate a cycle of inflammation that prevents you from really feeling like yourself again.

Additionally, gluten has one important superpower that most other foods do not — it causes leaky gut in everyone no matter whether you’re celiac, you’re gluten sensitive, or you have no reaction at all to gluten. A 2015 study looking at the effects of gluten on all three groups by a team including Dr. Alessio Fasano demonstrated that gluten spares no one. Leaky gut (or more the more medically appropriate term “gut permeability”) is a significant factor for those who react to gluten. It’s believed to be part of the mechanism behind triggering autoimmunity in the Functional Medicine world and is responsible for increasing the number of sensitivities you have to other foods.

When Gluten Free is Not Really Gluten Free

A study in 2014 found that 20% of gluten-free products tested for gluten were actually not gluten-free! They contained over equal to or above the 20ppm threshold that’s legal in the US. And while you can scour ingredient lists, still not feeling better may suggest that you’re still being exposed to gluten and preventing your body from healing.

The bottom line is that you MUST learn to read food labels so as to avoid hidden gluten. Fixating on ingredient lists isn’t full-proof… at all. Please know that this list is not the end-all-be-all of hidden gluten ingredients in food. Understanding gluten-free labeling is critical to mastering a gluten-free diet. No list or even mobile app can replace knowing what to look for.
