Of course, but so does the "regular" food industry as well. Adding random stuff to food isn't really how it works.

Bayesian, not logician. More freedom means more optimisation power.

One can also make the argument that the "natural food" industry should just deliver the natural food from the fields to the table and not mess around with it in the process.

There are some things with clear health benefits (eg preservatives to make sure the food doesn't rot, pasteurisation) but I agree with your point, if health was the only consideration.
