Candy is a food, and must be regulated by the US government. A maker not following them could be making unhealthy candy, or it could be a foreign maker, who don't follow US laws all thre timr. Or if you eat too much, THAT kind is unhealthy.
all of it unless there is no sugar in the candy. but I would probably say an Oreo with a reeses in the middle then dipped in chocolate deep fried drizzled in chocolate and powdered sugar. that would give you a cavity in one bite or a heart attack.
