A must watch and a must read

[trents]

This video: https://www.glutenfreewatchdog.org/news/lessons-learned-from-16-years-of-testing-food-for-gluten/ provides some great information with regard to compliance within the gluten free product industry and what to focus on with regard to avoiding getting glutened by misleading and false advertising. One surprising takeaway is that you really stand a good chance of getting glutened from lentils. 

and this article: https://www.glutenfreedietitian.com/how-much-gluten-is-20-parts-per-million/ does a good job of explaining the implications of what 20ppm means in real life over the course of a day's eating. It's really the total amount of gluten consumed (measured in mg) over a 24-hr. period that is important and not more than 10mg daily has been proven by research to guard against villi damage.  The 20ppm standard is designed to ensure you don't exceed that amount.

The takeaway from both the video and the article is that pills and other things we worry about as having gluten from cross contamination are very unlikely to constitute a real danger. The real CC danger is grain products and lentils. Purity Protocol gluten-free oats are recommended over those gluten-free oat products cleaned by sorting techniques.

I'm not a fan of the first site you mention, as she's never backed up her original claim that she would publish info publicly to back up her claim that General Mills gluten-free oat-based cereals contain levels of gluten that would make them unsafe. In fact, she seems to have totally dropped this claim altogether, aside from her recommending very expensive alternatives made using Purity Protocol oats.
