I disagree.

Actual food, meaning plants, animals, fungus is one thing.

Novel chemical substances should IMHO be guilty until proven innocent.

I realize there's a grey area between say, a plant, and some chemical isolated from the plant. There is a spectrum of whole fresh plant, dried plant, powdered plant, and then chemically isolated constituent of the plant powder. There are useful distinctions to make along that spectrum. And eating quantities of an extracted chemical from a plant that would be impossible to consume by eating the whole plant is one such useful distinction. (e.g. I could extract cyanide from apple seeds and concentrate it, and kill myself, when there's no way I could eat enough whole apples to kill myself with the cyanide.)

But synthetic chemicals not found in nature are entirely outside of that spectrum.
