I'd believe the thing about the carrots was about marketing for carrots before tricking the Germans. It's not like such things haven't been done. In the states there are plenty of scams (marketing) to convince us to eat more grains, or drink milk, or consume more {product}. Don't see why it wouldn't be the same anywhere else. We had a whole cartoon character dedicated to convincing people to eat spinach, which we were wrong about being particularly beneficial as well. These kinds of things, even when well intentioned, have secondary, harmful effects, that far outweigh their purported benefits.
