Morning musings about testing food for gluten & the Nima Sensor

The following is paragraph form of a tweet thread posted by @GFWatchdog to Twitter on March 21, 2019.

A few musings this morning about testing food for gluten & the Nima Sensor. Background, I have been commissioning testing of gluten-free food for about 15 years. Does this make me an expert? No. I am a dietitian fortunate to have learned from the experts—the scientists who specialize in testing food for gluten, including the late Dr. Mendez (you may recognize his […]

Please do not panic: The research abstract on the Nima Sensor and gluten-free restaurant meals presented at the ACG annual meeting is misleading

Yesterday evening I was just about to close up shop when three messages arrived almost simultaneously asking about a research abstract presented at the American College of Gastroenterology annual meeting entitled “Gluten Contamination of Restaurant Food: Analysis of Crowd-Sourced Data.” According to the abstract, study authors, including physicians from the Celiac Disease Center at Columbia University “analyzed data from a portable gluten detection device (Nima), collected across the USA during an 18-month period by users (n = 804) who […]

When an individual is maligned because his scientific opinion is at odds with the commercial messaging surrounding a food-testing gadget we have a problem

Background: As many of you know, Gluten Free Watchdog has been independently testing, assessing, and writing about the Nima Sensor for gluten for a couple of years. Third party testing data was recently released. As a result, we provided an update to our position statement on the testing gadget* (we are not able to recommend it).

In our post we included the following statement from Adrian Rogers, Senior Research Scientist at Romer Labs about the Nima Sensor and the third […]

Gluten Free Watchdog’s Updated Position Statement on the Nima Sensor for Gluten

At Gluten Free Watchdog we are not able to recommend the Nima Sensor consumer testing gadget* for gluten. Third party testing data released yesterday by Nima Labs has further solidified our position. This testing data confirmed what we’ve noted in our own testing with this gadget. There is no way to know whether a smiley face test result from the Nima Sensor is a true negative in terms of the gluten-free labeling rule (gluten below 20 ppm) or a […]

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.

The consumer sent all remaining product in the original container to Gluten Free Watchdog.
Gluten Free Watchdog sent the product to an […]
