I realize that some of us have other issues. Those who do must read the ingredient list on everything, including products labeled gluten-free. Soy is a top eight allergen, so in the US it will be clearly disclosed. Milk issues, either lactose or casein, are more common among celiacs, but milk is also a top eight allergen.
Maybe somebody can make a gluten-free, soy-free, dairy-free, sugar-free, egg-free, corn-free, potato-free, nut-free, tapioca-free cake mix. There will probably still be a celiac somewhere who can't use it. The rest of us won't be able to afford it.
I don't see how continuing to bash Betty Crocker (or each other) is helping anyone.
