"All natural" — sounds healthy, right? It's easy to understand why you might make that assumption. However, as it turns out, the FDA has no formal rules about what constitutes something as being "all natural." The unfortunate loophole is what allowed products like Snapple to label their teas and juices as "all natural" despite having been made with citric acid and high fructose corn syrup (although in 2009 the company started using sugar in its iced teas instead). The drink was even faced a consumer lawsuit over the issue but the case was rejected earlier this year. Still, the takeaway remains the same: Don't accept anything labeled as "all natural" at face value.
