Fructose Extra-splanchnic Metabolism and Its Effects on Systemic Flux of Substrates (FruPP)

Fructose Extra-splanchnic Metabolism and Its Effects on Systemic Flux of Substrates (FruPP)

In parallel to the dramatic rise in metabolic diseases and diabetes observed over the past fifty years, the generalization of added sugar in processed food led to a marked increase in fructose consumption in almost all countries, and epidemiological studies demonstrated that the consumption of sugar-sweetened beverage (containing at least 50% of fructose) is associated with the development of diabetes, hepatic steatosis, dyslipidemia and obesity.

The objective of the study is to measure the amount of fructose that escape first-pass hepatic extraction after oral ingestion (fructose+glucose), and gain insights into its metabolic fates with the use of tracers.
