@Oversleep, @Orlion Determined -- sorry for any confusion. I don't mean foreign things or complicated names for water -- I mean non-food additives (things like preservatives, some colorings, conditioners, emulsifiers, things like that) that are added to change the chemical makeup of the food or make it keep longer. Things that fall into this category are usually not dangerous or anything, but their presence does mean that whatever you're eating has been heavily processed.
(Also --- food labeling regulations, at least in the US, require that long latin or chemical names for ordinary things written on the tin are followed by the common name in parentheses! If it doesn't have the common name displayed, that almost invariably means the ingredient in question doesn't have a common name, just a scientific one.)
