The U.S. Food and Drug Administration is apparently beginning an effort to induce food producers into more honest labeling practices. This story describes letters that recently went out to a number of major food producers expressing concern on a number of areas. I am especially glad that they are apparently going after the practice of trumpeting claims that are technically true but mask the bad news, such as bragging about "No Trans Fat!" prominently displayed prominently on the label of a product that's high in saturated fat.
Unfortunately, the government can't make producers have a desire to honestly market their products. So it seems likely that this will always be a cat-and-mouse game.
