Trace Gluten in Your Favorite "Gluten-Free" Foods

Whole Grains


Most products marketed as "gluten-free" still contain a tiny bit of gluten ... some more than others. And people with celiac disease and non-celiac gluten sensitivity can have very different reactions (or no reaction at all) to these trace amounts of gluten in our foods.

If you find yourself experiencing gluten reactions to foods labeled "gluten-free," you may need to limit the amount of trace gluten in your diet.

But how do you do that?

First, you'll need to understand how these foods specifically marked "gluten-free" still are allowed to contain some gluten. You'll also need to learn how this trace gluten is measured, and how you might react to it. 

In the following table, you'll find major manufacturers of "gluten-free" products, plus the gluten parts per million (ppm) to which those products are tested. Note: products listed are reported as containing less than the stated level of gluten — for example a GF-10 product reportedly contains less than 10ppm of gluten, while a GF-20 product reportedly contains less than 20 ppm of gluten.

Please also note that I haven't tested these products myself; instead, I'm basing this table on information provided by the companies themselves, plus data provided by organizations that provide gluten-free certification.
