As far as I can tell, this document http://cspinet.org/new/pdf/order_on_m-d ... doc_44.pdf
is where that huffingtonpost so-called "quote" came from. Not defending Coke, which is pushing insulin bombs, but that huffingtonpost article seems to essentially be a lie, by taking a snippet out of context. The actual defense is much more complicated:
Defendants contend that no reasonable consumer could have been misled by vitaminwater’s labeling because: (1) the FDA-mandated label on each bottle bears the true facts about the amount of sugar per serving; (2) the allegations about brand names like “vitaminwater,” the one-word flavor names like “rescue,” slogans like “vitamins + water = all you need,” and sayings like “healthy as a horse” describe only puffery; and (3) no reasonable consumer could believe that vitamins and water are literally “all they need to survive” or all that “is in your hand” when holding a bottle that disclosed the presence of sugar.
