That blueberry granola bar you munched on this morning is very likely flavored with fake blueberries. In fact, the wrinkly so-called fruit pieces in your cereal, muffins, and bagels may not have anything in common with fruit at all. Although recorded on ingredient lists with vague names like “blueberry pieces,” “blueberry powder,” and “blueberry crunchlets,” it has been proven that the substances are typically mixtures of sugars, starch, and blue dye #2.
