Some people have the personal opinion that they just can't be bothered to learn to cook and to eat nice food. I'm trying to get my head around that. It's an alien concept to me.
Then there's the liquid feed nature of it. Put it in a cake and I might not be so critical of it.
I am trying to make myself remember that I have strong personal opinions and that I need to wait for science before leaping to the "it's stupid" conclusion.
This submission was nice because it was reasonably cautious - it has some safety advice, and warns people about the experimental nature of it. So, what people do with their bodies is mostly up to them and I don't try to stop them.
