In this randomized, controlled cross-over study, effects of oral palm oil and canola oil ingestion will be investigated in young, healthy lean subjects. Hepatic glucose fluxes will be assessed by two independent methods, in vivo magnet resonance spectroscopy (MRS) and the deuterated water/acetaminophen method, which also allows for the determination of glycogen cycling rates. Furthermore, hepatic phosphorus metabolites and liver fat content will be monitored by MRS.
