You seem to have projected a fear or intent into the comment which wasn't intended or explicitly described. I mostly agree in that taste is subjective, "There's no accounting for taste". Personally, I find those things unappetizing. As I said above, this is my bias. You asked for an example of something which I would regard as a highly processed food. I provided one. I cannot satisfy your other inquiries.

Although I will say that I have suspicions around the industrial processes for food additives and dyes. Yellow 6 for example is petroleum or coal tar derived. I'm sure the relevant regulatory bodies have approved these things, but I am not convinced that it is something I would like to consume personally.

Perhaps the burden should be on the manufacturer? I'm not sure where the discussion would lead if I had to rationalize every industrial by-product I preferred not to eat?

Again, there's no accounting for taste.
