Effect of Barbecue Food and Beer on the Antioxidant System of Rat Liver

[Objective] The reference of the scientific diet for human body health was provided through the experiment..[Method] The rats were fed with barbecue(BBQ) food and beer and another group as CK was fed with non-BBQ food and pure water.The activity of superoxide dismutase(SOD),the activity of catalase(CAT),the ability of ·OH radical-removing,the reducing power and the content of malondialdehyde(MDA) in rat liver were measured by the spectrophotometric method and the data was analyzed.[Result] The BBQ food and beer would resulted in the reduction of the capacity of antioxidant of liver,particularly for significant decrement in the activity of SOD and CAT,and the ability in the ·OH radical-scavenging and reducing power was also decreased,which were not significantly difference with those of CK,and the content of MDA was significantly increased.[Conclusion] A diet of lots of BBQ food and beer would decrease the capacity of antioxidant of liver.Therefore the barbecue food and beer in diet should be appropriately reduced and the addition of some natural antioxidant food was beneficial to the health of human body.
