I don't think any of this data justifies a ban even for the worst offenders, and the comparison to Big Tobacco is pretty comical hyperbole.

Feels a bit overkill to ban these ingredients given the culinary uses, even in home cooking for things like gluten free baking and salad dressings, simply because they're mildly unhealthful. I can think of many common things from both home cooking and commercial cooking that present a far higher risk that are normalised... and health honestly is not everything.
