I find it pretty disingenuous to write that it's just 100% fresh orange juice, and I don't think it should be legal to misrepresent your product in such a way.

I mean, the reason they're allowed to do it is because they're technically correct within the limits of what the FDA describes as "100%".

(3) If the beverage contains 100 percent juice and also contains non-juice ingredients that do not result in a diminution of the juice soluble solids or, in the case of expressed juice, in a change in the volume, when the 100 percent juice declaration appears on a panel of the label that does not also bear the ingredient statement, it must be accompanied by the phrase "with added ___," the blank filled in with a term such as "ingredient(s)," "preservative," or "sweetener," as appropriate (e.g., "100% juice with added sweetener"), except that when the presence of the non-juice ingredient(s) is declared as a part of the statement of identity of the product, this phrase need not accompany the 100 percent juice declaration.

but it's still horse hockey. I don't drink almost any juice - it's all too sweet for me. I drink tonic water (which has its own problems like salt).
