I've found that "it's not natural" = "it makes me uncomfortable"/"it's outside of my realm of experience"/"it scares me"

I don't see any of these people who say "it's not natural" eating roots and berries for lunch. Unpack that and you'll find that it means it doesn't fit into their idea of a social norm. And the other is feared.
