In recent years, the popularity of "natural" products has skyrocketed, and food companies have tapped into it. Bubly, one of the famous flavored sparkling waters, is a perfect example of product containing "natural flavors," but what does it really mean?

The FDA defines "natural flavor" as any ingredient "whose significant function in food is flavoring rather than nutritional." The origin of a product's "natural flavors" may be complicated since a single flavor can come from up to 100 different sources.

However, there is no need to worry since these so-called natural flavors won't prove harmful. As Cooking Light clarifies, any ingredients used by manufacturers must pass expert and scientific review to fall under the FDA's category of "generally recognized as safe," or GRAS.
