" The process of digestion of carbohydrates is a disassembly of the larger, complex molecules of starches to yield sugars, and this elemental and straightforward process begins in your mouth. So simple is the process that some starches are rendered into sugars through chewing and saliva even before they hit your throat. The result is a long list of sugars, but these in turn reduce to two in the main: glucose and fructose. "
