Are Quaker Oats considered gluten free?

Quaker Oats are a popular brand of oatmeal and cereal products. Many people wonder if Quaker Oats contain gluten or are considered gluten-free. The short answer is that most Quaker Oats products are gluten-free, but some varieties may contain traces of gluten from cross-contamination.

Gluten is a protein found in grains like wheat, barley, and rye. For people with celiac disease or non-celiac gluten sensitivity, consuming gluten can cause negative health effects. That’s why it’s important for those following a gluten-free diet to understand which Quaker Oats products contain gluten and which are gluten-free.

In this comprehensive guide, we’ll cover everything you need to know about the gluten content of Quaker Oats, including:

– What makes oats gluten-free or not
– Testing methods to detect gluten
– Quaker’s statements about gluten in their oatmeal
– Which Quaker Oats products are gluten-free and which contain gluten
– Risk of cross-contamination
– Tips for safely eating Quaker Oats on a gluten-free diet

Understanding the gluten content of Quaker Oats will empower you to make informed choices about the safety of Quaker Oats and oatmeal for your gluten-free lifestyle.

What Makes Oats Gluten-Free or Not?

Oats are naturally gluten-free grains. However, they can become contaminated with gluten during growing or processing if they come into contact with grains that contain gluten like wheat, barley, or rye.

Here are factors that determine whether oats and oat-based products like Quaker Oats are gluten-free or not:

Purity of the Oats

Oats that are guaranteed pure with no contamination from gluten-containing grains are considered gluten-free. This includes oats labeled “gluten-free” or certified gluten-free.

Processing Equipment

If equipment used to harvest, transport, or process oats is also used for gluten-containing grains, there is a high risk of cross-contamination. Oats processed on shared equipment are more likely to contain traces of gluten.

Manufacturing Facility

Like shared equipment, facilities that process oats as well as wheat, barley, and rye also have a risk of cross-contamination through airborne gluten particles. Oats processed in a shared facility have a higher chance of gluten exposure.

Labeling Standards

In many countries like the United States, Canada, and Europe, products labeled “gluten-free” must meet strict standards limiting gluten to less than 20 parts per million (ppm). Oats and oat-based foods labeled gluten-free adhere to these regulations.

By considering all of these factors, you can better understand the likelihood of Quaker Oats and other oat products containing traces of gluten or being processed safely gluten-free.

Testing Methods to Detect Gluten

Several scientific testing methods are used to detect the presence of gluten in oats and assess the gluten content of Quaker Oats:

ELISA Testing

The ELISA (enzyme-linked immunosorbent assay) test is the most widely used method to detect gluten. This lab test uses antibodies that bind to gluten proteins. Even small amounts of gluten as low as 5-10 ppm can be detected.

PCR Testing

PCR (polymerase chain reaction) testing amplifies DNA sequences unique to gluten-containing grains like wheat, barley, and rye. It provides quantitative results to measure gluten content in parts per million.

Mass Spectrometry

This analytical technique identifies and quantifies specific protein sequences unique to gluten. It can differentiate between contamination from wheat, rye, or barley.


The R5 antibody recognizes the most immunoreactive sequences of gluten. This test is sensitive to a broad spectrum of gluten protein types. An R5 ELISA value below 20 ppm indicates gluten-free.

Field Test Kits

Rapid test strips and ELISA kits allow gluten testing onsite at manufacturing facilities to identify contamination and verify gluten-free status.

Regular gluten testing provides quality control for oat producers and reassurance to gluten-sensitive consumers that Quaker Oats products accurately indicate gluten-free status. Testing methods are key to maintaining purity and preventing cross-contact with gluten.

Quaker Statements on Gluten in Oats

Quaker Oats brand frequently communicates about the gluten content of their products through their website, product FAQs, and consumer hotlines.

Here are some key messages Quaker conveys about gluten and oats:

Many Products Labeled “Gluten-Free”

Quaker states that any products labeled “gluten-free” meet all FDA requirements to use this label claim, restricting gluten levels to less than 20ppm.

“Good Source of Fiber” Label Indicates Gluten-Free

Products that contain the “Good Source of Fiber” statement on the package are considered gluten-free by Quaker, while those that don’t have this label may contain gluten.

Risk of Cross-Contamination

Quaker acknowledges that even gluten-free oats run a “slight risk” of cross-contact with wheat flour during farming, transportation, or processing.

Follows Gluten-Free Purity Protocol

Quaker assures consumers they follow a purity protocol to prevent wheat, barley, rye or their cross-contact during the growing and milling process for their gluten-free oats.

Notes Shared Equipment Use

For items not labeled gluten-free, Quaker states facilities and equipment also process wheat-based products, with risk of gluten exposure.

By providing this information, Quaker Oats demonstrates transparency about gluten content and standards for keeping gluten-free oats uncontaminated. Their communication helps gluten-free consumers understand how they source and process oats to minimize gluten risk.

Quaker Oats Products: Gluten-Free or Not?

Based on product labeling, testing, and manufacturing, here is the gluten status of different Quaker Oats items:

Gluten-Free Quaker Oats Products

  • Quaker Quick 1-Minute Oats
  • Quaker Steel Cut Oats
  • Quaker Old Fashioned Oats
  • Quaker Oat Beverages
  • Quaker Instant Oatmeal Packets (Plain and Flavored)
  • Quaker Oat Granola Bars (Plain and Flavored)
  • Quaker Rice Cakes
  • Quaker Corn Grits
  • Quaker Oat Flour

These Quaker products are labeled gluten-free, tested to verify purity, and processed in facilities following strict protocols to avoid cross-contamination with gluten-containing grains.

Quaker Products That May Contain Gluten

  • Quaker Chewy Granola Bars
  • Quaker Breakfast Squares
  • Quaker Breakfast Cookies
  • Quaker Instant Oatmeal Variety Packs
  • Quaker Oatmeal to Go Bars
  • Quaker Overnight Oats
  • Quaker Grits
  • Quaker Multigrain Hot Cereal

These products do not make a gluten-free claim and are produced in shared facilities that also handle wheat ingredients, so there is a risk of trace gluten exposure. Individual tolerance varies regarding these products.

Always check packaging for the “gluten-free” label or “Good Source of Fiber” statement to choose guaranteed gluten-free Quaker products. Avoiding varieties with wheat, barley, malt, and ambiguous “natural flavors” further reduces gluten potential.

Risk of Cross-Contamination

Despite rigorous quality control, there is always a slight chance of cross-contamination of gluten into gluten-free oats and Quaker Oats during harvesting, transporting, processing, or packaging:

During Farming

If wheat is rotated with oats or grown nearby, wind can disperse gluten-containing grains into the oat crops.

Shared Harvesting Equipment

Combines, trucks, wagons used to harvest both oats and gluten grains may transfer traces of gluten to the oats.

Shared Processing Facilities

Even meticulous cleaning can’t eliminate all risk of gluten exposure in facilities that also mill wheat and other gluten-containing ingredients.

Airborne Particles

Gluten residue circulating in the air can settle on processing and packaging equipment surfaces.

Improper Labeling

Human error such as mislabeling products poses a risk of hidden gluten.

By understanding potential sources of cross-contamination with gluten, you can make an informed choice about the safety of Quaker Oats for your gluten-free diet. Seeking third-party certification and choosing Quaker’s gluten-free labeled products can provide added assurance.

Eating Quaker Oats Gluten-Free

Here are some tips for safely eating Quaker Oats products while maintaining your gluten-free diet:

Check Labeling

Look for an explicit “gluten-free” statement as well as the “Good Source of Fiber” label indicating GF status. Avoid vague “may contain wheat” warnings.

Evaluate Manufacturing

Choose Quaker oats processed in dedicated gluten-free facilities over those made in shared facilities.

Call or Email Company

Contact Quaker directly with any questions or concerns about gluten in specific products.

Try Small Portions First

When introducing new Quaker items, start with a small serving to test individual tolerance before larger servings.

Add Other Grains

Mix small amounts of Quaker Oats with certified gluten-free grains like corn or rice to further dilute any traces of gluten.

Rinse Thoroughly

Washing Quaker Oats before cooking can remove stray grains and reduce cross-contamination risks.

Avoid Cross-Contact

Prevent contamination by storing Quaker Oats separately from wheat-based products and thoroughly cleaning surfaces, utensils after preparing.

By taking these precautions, individuals who are highly sensitive can often still enjoy Quaker Oats without reacting. Many Quaker products offer a safe, satisfying gluten-free option.


Most Quaker Oats products are considered gluten-free to 20ppm and safe for gluten-free diets. However, some varieties may contain traces of gluten due to shared equipment or manufacturing in facilities that also process wheat.

To choose gluten-free Quaker Oats, opt for products labeled “gluten-free” or that have a “Good Source of Fiber” statement on the package. Avoiding cross-contamination during food prep and starting with small servings size can also allow you to safely eat Quaker Oats gluten-free.

Quaker provides useful information about their testing, purity protocols, and potential for cross-contact that empower gluten-free consumers to evaluate the gluten-free status of Quaker Oats. By understanding Quaker’s manufacturing processes and labeling indications, those avoiding gluten can continue enjoying hot bowls of creamy Quaker Oats.
