<rant>Artificial sweeteners are the foods industry's response to the fact that people want to be lied to and betrayed.
If I do not want the sugar in the coke, then serve me some water. Otherwise, let me alone with my unhealthy coke. That's next to low-fat cheese. This is as reasonable as lactose-free milk is, or vegan burgers are, or gluten-free bread. I am not talking about people with coeliac disease, I am talking to the thousands of other folks who think it is healthier to avoid essential ingredients. Don't eat it if you don't want to, but stop pretending. There is really healthy food available. Eat veggies and fruit.<\rant>
Although I agree with your general food thoughts, I think your rant would be better directed at those making and MARKETTING their products for PROFIT rather than any the improvement in anyone else's condition.
Chemical In Your Mouth aside:
I used to use a chemical in labs to prevent fish embryos from making pigment (so we could see everything going on in them as the grew). The pigment cells were still there, but they could not make the pigment molecule (melanin).
At first we thought of it as run of the mill chemical, not to worry about toxicity or disposal (dump down the drain). Eventually it was identified as mildly toxic and something to be disposed of in a particular way.
When I was in a lab in England, my boss told me, that when he was a kid, this chemical (Phenyl Thio Urea (PTU)) was used as a grade school lab demonstration that a common genetic variant in people can control if their ability to taste a specific chemical. They would have kids taste, keep records, and show difference. Kind of like tongue rolling.
Then they found out it was mildly toxic, and of course changed what they did.
(Life is full of these kinds of contradictions based on the historical development of knowledge.)
My Rant:
Reactions to new knowledge in food realm will be slowed by opposition of financial powers with interest in food production.
This gets into social structure, politics, and such.
Another issue with the food field is that it does not seem to be what I would call a mature field. There are lots of changes going on in what people think about basic issues. There is also a very large, the non-academic source of many people's awareness, is often profit driven and not too concerned with facts.
