The safety of natural flavors is a significant concern and is evaluated through a rigorous assessment process. The FDA requires that all flavors added to food be safe for consumption. However, the term "natural" does not necessarily equate to safety. Natural substances can still be toxic; for instance, certain naturally occurring toxins such as solanine in potatoes or cyanogenic glycosides in almonds can be harmful. As a result, toxicologists conduct thorough evaluations to ensure that natural flavors do not pose a health risk to consumers.
