Jeri is right; you have to read what is actually there on the label (see Principles of Literary Criticism by Ogden and Richards; they gave 10 simple reading errors made by Cambridge Uni postgrads in the 20s; the very first - not simply reading what's actually there!)
Companies have to pull off the trick of getting into their products what they want while staying within the law while simultaneously so wording the labels that they've covered themselves. And can get it past all except those who read closely.
