# Reading Gluten-Free Labels: Certifications, Ingredients, and Hidden Gluten By Gregory Wilson · Excerpt from Chapter 4 of *Celiac vs Me* A few months into all of this, I was standing in the cereal aisle at Whole Foods, holding two boxes. They were not the same brand. They were not the same kind of cereal. But they were both labeled gluten-free on the front of the box, and the labels did not look the same. One had a small logo that said *Certified Gluten-Free*, a third-party mark from an outside organization that had audited the manufacturer. The other just had the words gluten-free on the front. No seal. No certifier. Both said gluten-free. Both, presumably, were. I stood there for what was probably a minute and a half, because I had hit a thing nobody had told me about. There were tiers of gluten-free. ## Three sources, none of them enough on their own There are three sources of information you are going to use, for the rest of your celiac life, to decide whether a product is safe: **the certifications on the package, the ingredients on the label, and the community of people who have already eaten it.** None of those three is, by itself, enough. All three together are how you do this. A celiac who relies only on certifications will miss the great products that don't bother to certify. A celiac who relies only on label-reading will miss the products that read fine but are made on shared equipment in a flour-dusted facility. A celiac who relies only on the community will miss the products that nobody has gotten around to writing about yet. One phrase, more than any other, holds celiac eating together: ***signal, not gospel***. Every label is signal. Every certification is signal. Every Reddit comment is signal. Your body's own response is signal. None of them, on its own, is the whole truth. ## What 20 ppm really means The FDA's gluten-free labeling rule says a product calling itself gluten-free must contain less than 20 parts per million of gluten — about a single grain of uncooked rice dispersed through a full kilogram of cereal. Most celiacs tolerate that floor without intestinal damage. But it is not zero, and for some celiacs even 20 ppm is too much. Independent organizations certify at stricter standards: GFCO at 10 ppm or below, and the strictest common mark (associated with the National Celiac Association) at 5 ppm. They also audit the facilities. The layering, from highest reassurance to lowest: third-party certification → plain gluten-free claim → clean ingredients with no claim → ingredients fine but a "manufactured in a facility that also processes wheat" warning. ## The Rice Krispies trap The canonical example, the one that catches every newly-diagnosed celiac at least once: **Rice Krispies.** Rice is gluten-free. It would be reasonable to assume a cereal called Rice Krispies is gluten-free. I made that assumption. It was the Fig app that first told me I had been wrong. Rice Krispies contain malt flavoring. Malt flavoring is made from sprouted barley. Barley contains gluten. The headline ingredient does not tell you whether the product is gluten-free. The full ingredient list does. And the word you are scanning that list for, more than almost any other, is **malt**. Wheat is one of the FDA's Big Nine allergens, required to be flagged in bold. Barley and rye are *not* on that list. So a product can contain barley, and therefore gluten, with no bold warning. You have to read the full ingredients yourself, every time. You will, after a few months, develop a kind of label-reading peripheral vision. You'll pick up a package, your eyes will sweep the ingredient list, and either nothing will catch and you'll move on, or something will and you'll slow down. This skill is real, and you will get it. I promise. --- This is an excerpt from Chapter 4 of Celiac vs Me. The full chapter also covers where gluten hides in sauces (soy, Worcestershire, gravy, packet seasonings, marinades), the smaller traps (medications, lip balms, Play-Doh), how to think about beer, wine, and distilled spirits, the geography of where to actually shop (Whole Foods, Trader Joe's, Costco, the regional GF specialty stores), the real cost of eating gluten-free and how to manage it, and the community-knowledge tier that the labels and certifications can't replace. - [Paperback](https://a.co/d/0ci9KEzr) - [Kindle Edition](https://a.co/d/0dqv86CH) ## Related chapters - [The Day You Get the Celiac Diagnosis](https://celiacvsme.com/the-diagnosis/) - [The First Weeks of Celiac Life: Rebuilding Your Kitchen](https://celiacvsme.com/the-first-weeks/) - [Telling People About Your Celiac Diagnosis](https://celiacvsme.com/telling-people/) - [Eating Out with Celiac: Trust Signals, Dignity Signals, and the Bridgeport Ribeye](https://celiacvsme.com/the-table/) - [Celiac Travel: Road Trips, Hotels, and the Parking Lot Moment](https://celiacvsme.com/the-road/) - [The Holiday Calendar with Celiac: Thanksgiving, Birthdays, and the People Who Love You](https://celiacvsme.com/the-calendar/) - [The Body Underneath: Bloodwork, Healing, and the Real Goal](https://celiacvsme.com/the-body-underneath/)
