In other words, are you eating processed cheese for the protein, or for the potassium sorbate? Only one of these is a "chemical" is the vernacular.
The vernacular is wrong in this case and encourages ignorance. "Preservatives", "dyes", "perfumes", "thickeners", and "artificial sweeteners" are all words that everyone understands. We can say "artificial ingredients" instead if we want a catch all. The English language is really expressive.
"Chemicals" is a buzzword used a lot by hucksters to push sales through pseudoscience. We must demand better and more specific reasoning than "chemicals" if we want the words "shown by science" to be meaningful as well.
Edit: This seems to be your argument, that engineered is the same as non-engineered. Because they are all the same basic building blocks. Right?
Is the result of this process "grown"? "Made"? "Engineered"? All of the above?
I was just saying the vague and abused "chemicals" is a bad descriptor. It's fair to rail against "manufactured", "under-researched", or "engineered" ingredients.
When I hear hucksters marketing organic, GMO, or Soylent. I'm always cautious. Caveat emptor.
Edit: I'm not anti-GMO. Nor the concept of Soylent. But I use a headset rather than hold my phone up to my head. Even though there's no definitive proof we can get cancer from smart phones. I just think there is additional risk here.
Edit: Also, your "chemicals" point is like arguing that Global Warming doesn't exist because it's snowing today. It's true, but not relevant to the discussion.
