I haven't seen this show (yet) but knew to beware of non-US honey esp. honey from China for exactly that reason, it was not 100% honey. I rarely eat honey because it seemed to cause gut problems, even reliable local honey.
Even though I don't eat honey I'm going to start beekeeping this year because it's something I've wanted to do, good for my garden, good for the environment. Probably donate the honey to the food bank, we have many people here in poverty, some homeless. Better than adopting a pet because we can go on vacation and the bees will be fine on their own
FDA standards are not as good as they once were, ingredients labelled "natural flavoring" or some other bogus word that tells me nothing about
what is actually in it. My gut tells me later but I'd rather avoid problems in advance.
