Well dear reader this one is a bit more complicated to answer because not only does it involve the safety of how gluten free products are processed but it also has to do with lots and lots of advertising dollars that have gotten tied up in the mix and that is why there has become so much controversy around this topic. So I'm going to try and briefly break the main points as there are many articles floating around all over the Internet.
First off let me start with a few main facts:
- There was a Class 1 recall for 1.8 million boxes on October 8,2015 for a combination of plain Cheerios and Honey Nut Cheerios for undeclared wheat from their manufacturing location in Lodi, California.
- Cheerios uses "washed" oats and not certified gluten free oats. This means that these oats are mechanically separated from mainstream gluten grains and because of this, these oats are generally extremely gluten contaminated. For more information see the Gluten Free Watchdog article which explains the difference between purity protocol vs mechanical sorting of oats.
