You can't legislate good sense for people. I suppose you could make them sign a disclaimer if they buy a lowcarb product that they've read one of the popular lowcarb diet books and agree to follow it religiously.

Let them deal with their problems, or not, however they wish. Meanwhile passing laws that puts such a burden on food providers will just be a barrier to them providing lower carb foods for the rest of us.

I agree with having sugar alcohols, dietary fiber and total carbs stated on the back label, and a warning about sugar alcohols and the gastro effects. But anything other than that is just needless fussing.

Look at all the crap on cigarette packages. People still smoke.
