Process cheese food slices must contain at least 51 percent natural cheese. Imitation cheese slices, by contrast, contain little or no natural cheese and consist primarily of water and vegetable oil. Kraft, Inc. makes Kraft Singles, which are individually wrapped process cheese food slices. When Kraft began losing market share to imitation slices that were advertised as both less expensive and equally nutritious as Singles, Kraft responded with a series of advertisements informing consumers that Kraft Singles cost more than imitation slices because they are made from five ounces of milk. Kraft does use five ounces of milk in making each Kraft Single, but 30 percent of the calcium contained in the milk is lost during processing. Imitation slices contain the same amount of calcium as Kraft Singles. Are the Kraft advertisements deceptive?
