Brief Summary

High fructose intake is increasingly recognized as causative in development of prediabetes, metabolic syndrome and cardiovascular disease (CVD). The mechanisms underlying fructose-induced metabolic disturbances are unclear but are beginning to be unraveled. In contrast to metabolism of glucose, the breakdown of fructose leads to the generation of metabolites that stimulate hepatic de novo lipogenesis (DNL) and increased levels of both fasting and postprandial triglycerides. The key lipogenic transcription factor seems to be activated by fructose independently of insulin. However, it is still controversial whether fructose consumption increases DNL in man to the extent that it induces metabolic disturbances. Animal studies have shown that also the adipose tissue is responsive to fructose feeding fructose, and that high fructose-feeding induces insulin resistance and inflammation in the adipose tissue. The role of intestinal insulin resistance in fructose-induced dysmetabolism has not been studied in detail. The critical question is whether the metabolic disturbances are induced by calorie excess or by fructose per se.
