Abstract Objective To explore the influence of 30 day feeding test of health food containing caffeine on the physiological state of SD rat. Methods SD rats were randomly divided into five groups according weight :three health food containing caffeine(1.64, 3.28, 6.57 g/kg),one health food containing reduced caffeine(6.48 g/kg) and the control group. Haematological and biochemical parameters were measured at the end of experiment, and main organ tissue analysis was also performed. Results Weight at the end of 4 week, weight after absolute diet, total weight increased, and total food consumption and food consumption at the end of 4 week in 6.57 g/kg groups of male rats were decreased compared with the control group (P<0.05). Conclusion In comparison with 6.48 g/kg group, all those changes may be caused by overhigh caffeine in 6.48 g/kg group.
