Background Diet plays an unequivocal role in the development of obesity. Interestingly, recent studies have demonstrated that coffee products containing javamide-I/-II may be commonly found in the market. However, there is no information about in vivo effects of coffee containing javamide-I/-II (CCJ12) on obesity-related metabolic factors (body weight, LDL, HDL, total cholesterols, triglycerides, adiponectin, and leptin) in nonobese people. Objectives The objective of this study was to investigate in vivo effects of CCJ12 on these metabolic factors as well as inflammatory/cardiovascular disease risk factors [C-reactive protein (CRP), soluble E-selectin (sE-selectin), TNF-α, monocyte chemoattractant protein-1 (MCP-1)] in a nonobese model. Methods Sprague-Dawley male rats were fed a complete diet for 20 wk with either drinking water containing CCJ12 [coffee containing javamide-I/-II group (CG), n = 10] or unsupplemented drinking water [water control group (NCG), n = 10]. The amounts of javamide-I/-II in CCJ12 were quantified by HPLC. Water/food consumption and body weight were monitored weekly, and the concentrations of metabolic/inflammatory/cardiovascular disease risk factors were measured by ELISA. Results There was no significant difference in water/food consumption between the NCG and CG during the study. Also, no significant difference was found in average body weights between the groups either. In addition, after 20 wk, both groups did not show any significant difference in plasma LDL, HDL, and total cholesterol concentrations. Likewise, adiponectin and leptin concentrations were not significantly different between the groups. As expected, the 2 groups did not show any significant difference in plasma concentrations of CRP and sE-selectin. Furthermore, there was no significant difference in plasma concentrations of TNF-α and MCP-1 between the groups. Conclusions The data suggest that CCJ12 may not have significant effects on the metabolic/inflammatory/cardiovascular disease risk factors in the CG, compared with the NCG.
