Re: concentrate juice
I completely agree with tjlhb as he gave good reasons to avoid juice. But now that you have restated your question, I can give you another reason. Let's take orange juice as an example. In order to make concentrate, the juice has to be heated to the point where the water in the juice will evaporate and the equipment that does this is called an evaporator. The juice swirls through hot pipe coils to get heated and great care has to be taken not to burn the juice. It requires constant supervision and testing.
Even though the juice usually doesn't burn, you can imagine how it gets pretty hot. What does this high heat do to the vitamin C and other nutrition content? I can't help but think that it destroys some of it.
What about juice that's not from concentrate? I'm not completely sure but I think that it gets heated to, for pasteurization.
