Real sugar is processed by the body naturally. High fructose corn syrup is not. It stimulates insulin improperly and has some other suspected concerns. Aspartame/Nutrasweet/Equal is an excito-toxin just like caffeine and MSG. Sucralose is a sugar molecule that has been chlorinated so the body does not recognize it. The organic chlorine is the risk.

Too much natural sugar is still not good but if consumed with other foods that have complex structures, the digestive system takes longer to digest them.
