@Iluviaporos - Well, food is made up of chemicals, if you're going to break it down to its base components and that goes for every kind of food, not just the ones that have been processed.
I don't think every additive is good for you, but I don't like palmitate has side effects unless you eat too much of it, and it generally gets added to things so that they will be more healthy for you, not less.
The same can't really be said for things like gelatin though. But, companies are required to list everything in the ingredients list on the side of packaging, so if you're worried about this kind of thing, either check there or try to only get non-processed foods. There are plenty of yogurts on the market that haven't been tampered with like this, and yogurt is already a healthy food, it doesn't actually need to be low-fat.
