Health: Terminology overload! (food)

MKR

So I had a fun dilemma at the grocery store: I was trying to find things that are reasonably healthy for meals that don't involve much preparation (> 5 steps). The ingredients list on pretty much everything had some sort of corn syrup in it - like "corn syrup solids" and "corn syrup," even things that try to look healthy. The confusion comes from HFCS, which from what I understand is not healthy. There are a lot of things on the ingredients lists I can't identify, and it's bugging me.

So I'd like a comprehensive of common food additives that are generally considered bad, or at least not preferable.

I already know:
Trans-fat
Too much salt
High fructose corn syrup
Too much sugar

The quick and dirty way to see what's bad is look at the nutrition facts. Everything above the solid black bar(fat, cholesterol, sodium, sugar, etc.) is an upper limit. If you see something that has a percent daily value near 100%, don't eat it. Don't forget to look for serving size as well.

I don't think anything I buy has any part over 15 or 20%; most of it is in the 2-5 range.

Avoid partially hydrogenated and hydrogenated oils, although those are the transfats. I try to steer clear of things like monosodium glutimate (sp?) also.
