I would leave them intact, for this reason alone if for none other. Because it says
Sugar Crisp on the panel and not Golden Crisp. You can teach your kids all about Sugar Crisp, and Sugar Pops, and Sugar Smacks, and Sugar Frosted Flakes, and even
Super Sugar Crisp. Get them all hopped up just talking about sugar.
You can even use your faux Dean Martin-esque voice to sing the "Can't get enough of that Sugar Crisp." jingle to them.
You won't see Sugar anything on cereal boxes in the US anymore. Canada's a different story though.
