My understanding is that oats, as such, are gluten free, but that often processed oats on grocery store shelves are cross contaminated with gluten. if so, why aren't products like rice, especially bulk rice in bins not considered cross contaminated? Maybe they are in the sense that anything is possible. But only oats are automatically assumed to have cross contamination and therefore the necessity of using only oats labels as gluten free.Why isn't it also necessay to find, for example, rice packages that are labeled gluten free? Why are oats in a special category in this sense?
