Mexico put warning labels on dairy products that have artificial sweeteners, and as a result, companies started using way fewer of those sweeteners—down by almost a third. Meanwhile, Chile and Peru didn’t warn about sweeteners, and they actually started using more. So, it looks like warning people about artificial sweeteners might push companies to stop putting them in food.
