The simplest form of carbohydrate is the monosaccharide. Mono=single, saccharide=sugar. Glucose, along with fructose and galactose are single sugars important in human nutrition.
Only found naturally in a few foods, glucose is a moderately sweet sugar and is the most common body fuel oxidized by cells for energy. Supplied directly to the body from the digestion of starch, glucose can also be obtained through the conversion of other simple sugars.
Insulin, glucagon, and our pancreas and liver all help to keep blood glucose at optimal levels.
Glucose is a double edged sword. When not transferred to cells for energy and left in the bloodstream, glucose can have disastrous effects on our health.
Unable to reach cells and left in the bloodstream, glucose can cause diminished kidney function, loss of vision, poor wound healing, and nerve damage-causing loss of feeling in feet and legs.
