Cure for digestive diseases?

Define chemicals

Fair point. I'm referring to additives used to emulate natural food properties used in food manufacture which are increasingly being linked to disease manifestation through clinical testing.

I guess I'm also supposing that perhaps all artificial chemicals we ingest lead to detrimental health outcomes?

Smoking, drinking, pharmaceuticals... the list is endless

There is nothing in any link that would invalidate my knowledge concerning hazardous chemicals, I was a safety advisor to a research institute within a university, or the logic I have employed to emphasize that separating chemicals found in food into natural = safe and synthetic/artificial = hazardous, is simply wrong.

Id suggest listening to the links I added which it's clear you haven't

Synthesised = artificial in relation to chemicals.

Virtually everything in the realm of synthetic/artificial chemicals has had extensive toxicity testing. Usually it is the LD 50, which tests how much chemical either kills 50% of the subject animals (such as rats) or 50% of cultured mammalian cells. I knew someone who ingested a toxic chemical in a laboratory and the medics eventually contacted a retired scientist in a nursing home to find out the LD 50. As it happens the person had ingested more the dose lethal to 50% of rats (in a ratio to body mass), but after days on life support and other interventions, he survived. Artificial additives to food often have had more thorough testing than chemicals occurring naturally in food.

Like I said, each individual chemical, natural or man-made is unique as to its levels of hazard to a human ingesting it.
