The FDA regulates certain advertising verbiage for food products. Stuff like “zero calorie” or “no sugar”, you can read the law but its boring. Doesn’t leave much for creative interpretation.

But wait, the FDA doesn’t actually require a food to have no calories to say that it has no calories? It can actually have up to 5 calories per serving. And something can say it doesn’t have any sugar, when it has up to half a gram per serving (that one isn’t too bad, but still!)

This isn’t a vague acknowledgment that lying exists in food advertising, this is an actual codification of false advertising.
