General Mills is producing gluten-free Cheerios using what they term “validated gluten-free flour.”

General Mills determines gluten-free status of a “lot” of oat flour via a lot mean.

Further, General Mills determines gluten-free status of a “lot” of gluten-free Cheerios via a lot mean.

Oats and the Gluten-Free Diet: Q&A Part 2

Two weeks ago I posted on social media asking you to send me your questions on oats—anything that was on your mind. I did this because the situation with oats and the gluten-free diet is one of the most complicated issues I write about–something I’ve been doing for about 21 years.

Because you sent in so many questions, they are being answered in groups. This is the second Q&A post on oats. Some of your questions may have been slightly […]

Oats and the Gluten-Free Diet: Q&A Part 1

Last week I posted on social media asking you to send me your questions on oats—anything that was on your mind because as I stated, “The situation with oats and the gluten-free diet is one of the most complicated issues I write about–something I’ve been doing for about 15 years.”

I’ve actually been writing about oats for so long that I forgot just how long. My first article on oats was published in the scientific literature in 1997—21 years ago […]

It isn’t just oats that have gluten cross contact issues

We’ve known for well over a decade that standard oats are highly likely to arrive at a mill from the farm containing errant wheat, barley, and rye grain. But we also have a problem with errant gluten-containing grain showing up in other naturally gluten-free grains, seeds, and legumes, including millet grain and dried lentils.

This is happening in products labeled “gluten-free” as well as those labeled “certified gluten-free.” And it doesn’t matter if the food manufacturing plant is dedicated gluten-free. […]

Gluten-Free Quaker Oats & Testing with the Nima Sensor, R5 ELISA, & G12 ELISA

November 6, 2017

Please read this entire document very carefully. The information is presented in bullet point format to hopefully make complicated information a bit easier to understand.

Background:

A consumer tested a carton of Quaker Oats labeled gluten-free with the Nima Sensor consumer-testing device. Two samples—one cooked and one raw were tested. Both results were “gluten found”.
The consumer sent all remaining product in the original container to Gluten Free Watchdog.
Gluten Free Watchdog sent the product to an […]

General Mills removing gluten-free claim from Cheerios in Canada: Implications for US market?

As many of you have heard General Mills is removing the gluten-free claim from Cheerios sold in Canada. Gluten Free Watchdog reached out to General Mills to learn more about this decision and how it might impact Cheerios sold in the US. In particular, we asked about testing protocols and any changes to these protocols. These questions are motivated by our knowledge that an AOAC working group on gluten in oats was established because “Standards and methods are needed […]

August 23, 2017

Glanbia Agribusiness is a purchaser and processor of grain in Ireland. They have recently begun to sell their OatPure™ gluten-free oats to manufacturers in both North America and Europe, through their sister company, Glanbia Nutritionals.

Oats and the Gluten-Free Diet: Something for Everyone!

In Honor of Celiac Disease Awareness Month, Gluten Free Watchdog is writing a series of articles (the goal is one per day during the month of May) related to the gluten-free diet–currently the ONLY treatment for celiac disease. 

Post (#10)…

I have written more on oats for both scientific and general audiences than any other issue related to the gluten-free diet. My first article published in the scientific literature in 1997 was on oats and there are at least 27 posts on […]

Gluten Free Watchdog Updated Position Statement on Oats

Background: Two scientific publications from PepsiCo scientists provide us with the best data to date on the state of contamination of oats sold as gluten-free in the US (1, 2). Extensive testing by PepsiCo found 1 in every 57 servings tested (0.25 g sample taken from each 45 to 50 g ground serving) to contain gluten at levels at or above 20 parts per million using the R5 ELISA R7001 assay. The scientists point out that the number of […]

Quaker researchers publish a second study highlighting the difficulties associated with testing oats for gluten contamination

Note: This is one of two companion articles published today on oats. An updated position statement on oats from Gluten Free Watchdog will be published in the near future.

PepsiCo scientists recently published a second article in the scientific peer-reviewed literature on the difficulties associated with testing oats for gluten contamination. This article entitled “Kernel-based gluten contamination of gluten-free oatmeal complicates gluten assessment as it causes binary-like test outcomes” compliments their first article entitled, “Gluten-containing grains skew gluten assessment in […]
