I used to work in a flavor company. "Natural" strawberry flavor also uses an ingredient extracted from rotten eggs. It has to have at least some of what it says it is (like strawberry extract) to be called what it is, but this can be like one drop in a barrel. Also, if you add even the smallest amount of natural flavor to an artificial flavor, you can call it "Natural and Artificial."<p>Basically, the artificial flavors are really cheap, so people try to avoid the natural stuff when customers don't care.<p>But on that note, there are some good ingredients, since some flavors are too hard to create unless you use the real stuff (like black tea -- you just overbrew it to make a concentrate).
