    In this study, a high carbohydrate diet was replaced with a diet higher in monosaturated fats.  The result was: a lower carb diet with resultant increase in monosaturated fats resulted in a reduction in triglycerides, reduction in systolic B/P, increase in HDL, and resultant decrease in CVD risk

    Fructose intake associate with increased fasting blood sugar, elevated triglycerides, and elevated systolic blood pressure--all parameters of metabolic syndrome.

fructose uric acid metabolic syndrome sugar

  • HFCS consists of fructose and glucose mixed in a variety of concentrations, but most commonly as 55% fructose and 45% glucose
  • In the United States, HFCS and sucrose are the major sources of fructose in the diet, and HFCS is a major ingredient in soft drinks, pastries, desserts, and various processed foods
  • fructose and glucose are metabolized in completely different ways and utilize different GLUT transporters

  • In the liver, fructose bypasses the two highly regulated steps of glycolysis, catalyzed by glucokinase/hexokinase and phosphofructokinase both of which are inhibited by increasing concentrations of their byproducts. Instead, fructose enters the pathway at a level that is not regulated and is metabolized to fructose-1-phosphate primarily by fructokinase or ketohexokinase
  • Fructokinase has no negative feedback system, and ATP is used for the phosphorylation process. As a result, continued fructose metabolism results in intracellular phosphate depletion, activation of AMP deaminase, and uric acid generation which is harmful at the cellular level
  • Uric acid, a byproduct of fructose degradation,
  • Uric acid inhibits endothelial NO both in vivo and in vitro, [15] and directly induces adipocyte dysfunction
  • Serum uric acid increases rapidly after ingestion of fructose, resulting in increases as high as 2 mg/dL within 1 hour
  • Uncontrolled fructose metabolism leads to postprandial hypertriglyceridemia, which increases visceral adipose deposition. Visceral adiposity contributes to hepatic triglyceride accumulation, protein kinase C activation, and hepatic insulin resistance by increasing the portal delivery of free fatty acids to the liver
  • Several reviews have concluded that intake of both fructose and HFCS by children and adults was associated with an increased risk of obesity and metabolic syndrome
  • Sucrose is a disaccharide that is comprised of fructose and glucose
