Sugar crash 4801122 223613847 2008-07-04T21:59:37Z 74.71.165.70 {{expert|date=June 2007}} A '''[[sugar]] crash''' or '''[[glucose]] crash''' is a concept in American [[folk medicine]] which refers to fatigue one feels after eating a large quantity of sugary foods. After intake of food with high levels of [[glucose]], the glucose is absorbed from the [[gastrointestinal tract]], increasing the [[blood glucose|blood plasma glucose]], which in turn increases the production of [[insulin]]. Increase in insulin in the blood plasma reduces the glucose level in blood. The glucose consumption of the skeletal [[muscle]]s will increase as well. Overall, the insulin production and the muscle demand will reduce the blood glucose level dramatically, leading to the symptoms of a "sugar crash." The problem is that the American Dietetic Association, by way of real research, says a "sugar rush" does not exist. In addition, a "sugar crash" does not exist. There may be isolated cases in persons who do not have perfectly functioning pancreases, in which a sugar crash does occur. Approximately 25-percent of Americans have some sort of problem regulating blood glucose levels after eating any carbohydrate, not just sugar. The rest of the population, children included, regulate glucose levels normally. Therefore, no "rush" means no "crash." ==See also== *[[Hypoglycemia]] *[[Hyperglycemia]] {{health-stub}} [[Category:Metabolic disorders]]
