I would not go for its chemical contents.....way too laid back to be concerned about it. People should be dying in millions because of coke and pepsi; there should have been an epidemic by now, if it was that harmful. By the way, the common salt we eat is made up of sodium and chlorine?? (forgive me if i am wrong). Man.....just imagine if they were to break up in our stomach....OMG..... I m getting paranoid. Too much water is poisonous too, so is too much pure oxygen. I believe we take in arsenic too through many things but it is harmless untill the intake crosses a certain threshold. For paranoid people, the best thing to do would be to stick to kandamul and saag :) I dont think coke or pepsi has somehting that we should be too much concerned about. Having said that, I wont be drinking more than 1 liter of it in a day at any rate though.
