Fuzhuan tea reverses arterial stiffening after modest weight gain in mice

Abstract Objectives The aim of this study was to examine the effects of a Western diet (WD) and supplementation with Fuzhuan tea on large artery stiffness, as determined by aortic pulse wave velocity (aPWV). Methods Mice were subjected to a standard diet (SD; n = 12) or WD (n = 10) for 7 mo, and were then separated to receive nonsupplemented drinking water (SD-W and WD-W) or water supplemented with Fuzhuan tea (SD-T and WD-T) (200 mg/kg daily); mice were then maintained on their respective diets for an additional 2 mo. Results After the initial 7-mo feeding period, WD elicited a modest and significantly greater increase in body weight than did SD (39.6 ± 0.71 versus 34.5 ± 1.16 g; P P P P Conclusion The results of the present study suggest that the increase in arterial stiffness after modest, diet-induced weight gain can be reversed by supplementation with Fuzhuan tea.
