Personally I feel the fewer artificial chemicals you put in your body the less stress you put on your systemic health, but that's just me. I think it's kind of strange that the R&D departments at all these processed food factories seem to feel that you have to keep adding chemicals with longer and longer names that no one can pronounce in order to "improve" the product.
Things that are marketed to our children seem to be the worst offenders. I guess they figure it will take longer for adverse effects to show up in more vigorous systems or something.
