They aren’t better for you, so why are you eating them?
They’re not only not better for you, but almost certainly worse, nutritionally. I don’t want “plant based” food. I want affordable lab-grown meat that is indistinguishable, in both nutrition and taste, from the real thing. And I’d want it in space, too.
[Update a few minutes later]
I just got around to reading it myself. It’s not about the calories or the salt, or even the saturated fat. If you don’t eat meat, you’re not getting (among other things) choline, which is essential for everyone, but particularly for growing kids.
