Document Summary
Glycemic index: the effect a food has on blood glucose levels relative to feeding pure. Once simple sugars are in the blood, they will be directed to various locations. Fructose & galactose are transported directly to the liver and converted to glucose, which can either be: Sent into blood stream to maintain blood sugar levels (110mg/dl) **see next slide. Glucose is transported to the liver and either: Sent into blood stream to maintain blood sugar levels (110mg/dl) Converted to free fatty acids (that are sent out as cholesterol and dropped off at muscle and fat cells) Stay in blood to maintain blood sugar **see next slide. Be taken up by muscle cells to be converted to the storage form glycogen. Be taken up by other tissues for energy for cns brain and other parts of cns for glycolysis (for energy) and red blood cells. Be excreted by kidneys via urine in excess.
