Aim: To investigate the acute effects of the ingestion of a fructose-containing beverage combinedwith fat on postprandial lipoprotein metabolism. Methods: Twelve young healthy Japanese women with apolipoprotein E phenotype 3/3 were enrolled in this study. At each of four sessions, the subjects ingested one of four sugar beverages containing fructose and/or glucose (total: 0.5g/kg body weight) combined with OFTT cream (1g/kg, 0.35g/kg as fat) in a randomized crossover design. The four sugar beverages were as follows: 100% (w/w) fructose (F100), 90% fructose+10% glucose (F90G10), 55% fructose+45% glucose (F55G45) and 100% glucose (G100). Venous blood samples were obtained at baseline and 0.5, one, two, four and six hours after ingestion. Results: The serum concentrations of TG in the F100, F90G10 and F55G45 trials were significantlyhigher than each fasting value at two and four hours, and returned to baseline at six hours, except inthe F100 trial. The concentrations at four hours and the incremental areas under the curve for thehepatic triglyceride-rich lipoprotein-triglyceride (VLDL-TGTM) levels in the F100 and F90G10 trialswere significantly higher and larger, respectively, than those observed in the G100 trial. Meanwhile,the concentrations of RLP-TG and apolipoprotein B-48 peaked at two hours in the G100 trial, versusfour hours in the other trials, and did not return to baseline at six hours, except in the G100 trial.At four hours, the ⊿apoB48 tended to be higher in the F100 trial than in the G100 trial. Conclusions: The ingestion of a high-fructose-containing beverage with fat cream delays the clearance of chylomicron and its remnant derived from the intestine and enhances the secretion of triglyceride-rich lipoprotein particles from the liver, thereby inducing postprandial lipidemia, even in young healthy women.
