Increased fructose consumption has sex-specific effects on fibroblast growth factor 21 levels in humans.

ABSTRACT:

Objective

Fibroblast growth factor 21 (FGF21), a primarily hepatic hormone with pleotropic metabolic effects, is regulated by fructose in humans. Recent work has established that 75 g of oral fructose robustly stimulates FGF21 levels in humans with peak levels occurring 2 h following ingestion; this has been termed an oral fructose tolerance test (OFTT). It is unknown whether prolonged high-fructose consumption influences the FGF21 response to acute fructose or whether biological sex influences FGF21-fructose dynamics.

Methods

Thirty-nine healthy adults underwent baseline OFTT following an overnight fast. For the high-fructose exposure protocol, 20 subjects ingested 75 g of fructose daily for 14 ± 3 d, followed by repeat OFTT. For the control group, an OFTT was repeated foll
