I think the underlying bugaboo is "untested", particularly when referring to something considered "fragile".
People trust traditional techniques of preparing food because they have proven successful at their intended goals. When you start messing with people's food, they become suspicious as to whether you know the full repercussions of what you are doing.
So the injection of a novel element is considered "artificial" - despoiling the "natural" -- e.g. time-tested technique, and possibly disturbing something fragile -- e.g. human health.
Similarly, people are quite reactionary when it comes to open spaces and nature because they see a system that appears to be in balance and has survived the test of time. They oppose altering the current state of affairs because they are sure some unintended side effect will screw things up.
On the one hand, it's laudable to have these goals, but if they used the standard language of conservatism, traditionalism, etc, they would be branded as reactionaries, so the spirit of the age is to invent new words like "artificial" and "natural" that are less loaded with politics, even though it is all just conservatism at its roots.
