Testing Oat Products Using the Nima

Please watch the video Using Nima to test heterogeneous samples such as oats before watching this video. It is available at In the current video I test a box of “gluten-free” Cheerios from the 2015 recall and a carton of regular Quaker oats using Nima.

“He gave my son veal dredged in flour and a side of gluten free pasta cooked in the same water as regular pasta” Are restaurants taking gluten-free requests less seriously?

This week I received an email from a member of the Gluten Free Watchdog community about a recent restaurant experience. It is printed here with permission:

The lab was able to test three extractions. The results are 78 ppm, > 84 ppm, > 84 ppm gluten indicating that at least some of the grain is wheat and/or barley.
