Cheerios is analyzed under general rules for this region. Cheerios are made from oats, and in the US General Mills labels Original (and many flavors of) Cheerios as gluten-free, using a process that mechanically sorts wheat, barley, and rye out of the oat supply. By that labeling, they are marketed as safe.
The Full Answer
Cheerios are made from oats, and in the US General Mills labels Original (and many flavors of) Cheerios as gluten-free, using a process that mechanically sorts wheat, barley, and rye out of the oat supply. By that labeling, they are marketed as safe.
However, organizations including the Gluten Intolerance Group and Celiac Canada have raised concerns that this sorting method does not guarantee every box is consistently under 20 ppm, and some celiacs report reactions. Outside North America (e.g., UK/EU/Australia), standard Cheerios may contain barley or not carry a GF label at all.
If you have celiac disease, weigh the GF labeling against the expert caution: many celiacs avoid Cheerios in favor of cereals made with purity-protocol certified gluten-free oats. Always check the label for your country.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — 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 — stricter than the FDA's 20 ppm threshold for "gluten-free" labeling.
- Parts Per Million (ppm)
- Parts per million (ppm) is a unit of measurement used to quantify gluten concentration. Labeling laws in the US and Europe permit a maximum threshold of 20 ppm, while Australia requires no detectable gluten (0 ppm).
- Avenin (Oats)
- Avenin is a protein found in oats that is structurally similar to gluten. While most celiacs can tolerate pure, uncontaminated oats, a small percentage of celiacs react to avenin itself.
- 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.
