Gluten cross-contact in farm fields is never far from my mind

So, there I was in the beautiful Cotswolds thinking about gluten cross-contact… This spring we were on vacation in England walking the Cotswold Way. We walked through stunning fields of beautiful rapeseed flowers. While taking it all in, I noticed the very occasional bunch of white flowers. These turned out to be radish plants based on the plant identifier on my phone. Of course, both rapeseed and radish are naturally gluten-free. BUT my brain leapt to how these farm fields...

Gluten-Free Surprises on a Walking Vacation in the Cotswolds

We were fortunate enough to go on a family vacation in England this spring, walking about half of the famed Cotswold Way that goes from Chipping Campden to Bath (or vice versa). This trail runs through the most beautiful Cotswold villages, farmland, and woodland. Unbelievably, even though we were walking, I actually gained instead of lost weight. And that is a good thing! With a lot of research and advance planning, I was able to eat ample breakfasts, lunches (when an...

New Gluten Threshold Study from Australia

In Brief: A Randomized Double-Blind, Placebo-Controlled Dose-Response Study to Assess the Gluten Threshold Dose in Celiac Disease was conducted by a team of researchers from Australia and recently published in the journal Gastroenterology. A primary goal of the research was to determine the minimal dose amount of gluten required to cause an immune response--specifically an interleukin-2 (IL-2) response in adults with celiac disease adhering to a gluten-free diet. Among other objectives, the researchers looked at the lowest observed immune effect level...

Gluten-free and wheat-based crackers hung out together: Will the Nima Sensor pick up any cross-contact?

One of Gluten Free Watchdog’s criticisms of the Nima Sensor is that it is unlikely to pick up uneven cross contact in a food sample that has not been homogenized—ground up in a blender for example—prior to testing. To help address this issue the Nima Now team suggests using, “the teeth on the bottom of the capsule cap to dab food from different areas of your plate.” Let’s see how well that works… A labeled gluten-free mini rice cake and a...

Gluten Free Watchdog testing experiments using the updated Nima Sensor 2026

Gluten Free Watchdog is not planning an in-depth assessment of the “new” Nima Sensor. We will test products as issues are brought to our attention. To that end, we tried unsuccessfully to update the first generation Nima we purchased years ago. Unfortunately, it is too old to receive firmware updates. As a result, a new Nima and two boxes of capsules were sent free of charge from Nima Now. From what we understand, if you have a first generation Nima...

A silly thing is happening with the relaunch of the Nima Sensor

A silly thing is happening with the relaunch of the Nima Sensor. The fact that Gluten Free Watchdog sends samples to the lab Bia Diagnostics for testing using the scientifically validated R5 ELISA is seemingly being used as a talking point to help confirm the validity of the sensor. From the Nima Now website: “That performance was validated by BIA Diagnostics, a globally recognized allergen-testing laboratory whose work is trusted by the celiac community and organizations such as Gluten Free Watchdog.” “For the...

FDA issues a request for information regarding labeling and preventing cross-contact of gluten in packaged food

On January 21, FDA issued a request for information regarding labeling and preventing cross-contact of gluten in packaged food. The FDA reached out directly to Gluten Free Watchdog encouraging us to submit comments to help inform their decision-making process. According to the email received, the RFI seeks public comments and data on four main areas: Oats and gluten contamination through cross-contact with gluten-containing grains. Undisclosed ingredients where gluten sources may not be apparent to consumers (e.g., "malt extract" from barley). Consumer perspectives on gluten avoidance, purchasing decisions,...

Is the FDA enforcing the gluten-free labeling rule: You be the judge!

On October 1, 2024, the Food and Drug Administration updated the way in which consumers must go about reporting food-related issues to the agency. Instead of contacting an FDA consumer complaint coordinator, reports are now filed with the Human Foods Program either by phone or through the online safety reporting portal. Gluten Free Watchdog also was asked to use the portal. According to an email sent out by the FDA, “This streamlined process will expedite delivery of inquiries and complaints to...

Gluten Free Watchdog 2025 Summary Report

Testing: Testing was commissioned by GFWD and done by Bia Diagnostics, LLC. The sandwich R5 ELISA and cocktail extraction were used. When appropriate, the competitive R5 ELISA also was used. Most samples were tested in duplicate; oat samples were tested in triplicate due to the heterogeneous (uneven) distribution of potential gluten cross contact. Findings: 104 unique products were tested and released in 2025—almost all of them subscriber requests. 75 unique products were labeled/represented as gluten-free. 6 unique products labeled gluten free contained quantifiable gluten...
