It's also worth noting that not everything in the Free From section is free from gluten. In all our major supermarkets in our town, the Free From area includes Free From: gluten, dairy, eggs, animal produce, and probably other things I can't recall off the top of my head.
The only things I go there for are GF Soy Sauce and GF Worcestershire Sauce. I eat a wide and varied diet, but all foods are naturally GF, as opposed to being reformulated to swap in other ingredients.
