We see high fructose corn syrup, sorbitol, dextrose, xylitol, and sugar in our packaged foods along with white, blue, pink, brown and now green packets to spruce up that iced tea in restaurants. If you are keeping up with the trends, agave nectar and stevia are all the rage. But have you ever stopped to wonder what all the sweeteners really are? Regardless of where you ended up on the flowchart or what you think of your choice, understanding what the sweetener is and where it comes from is the first step.
