Influence of integral and decaffeinated coffee brews on metabolic parameters of rats fed with hiperlipidemic diets

The objective of this study was to evaluate the inf luence of integral and decaffeinated coffee brews (arabica L and C. canephora Pierre) on the metabolic paramet ers of rats fed with hyperlipidemic diet. Thirty ma le Wistar rats (initial weight of 270 g ± 20 g) were used in the study, which were divided into six groups five each. The treatments were normal diet, hyperlipidemic diet, h yperlipidemic diet associated with integral coffee arabica or canephora brews (7.2 mL/kg/day) and hyperlipidemic diet associated to decaffeinated arabica, or caneph ora brews, using the same dosage. After 41 days, performance a nalyses were conducted.The rats were then euthanize d and the carcasses were used for the analysis of dried ether extract and crude protein. Fractions of adipose ti ssue were processed for histological analysis. There was a re duction in weight gain and accumulation of lipids i n the carcasses, lower diameter of adipocytes and a lower relative weight of the liver and kidneys of rats fwith hyperlipidemic diet associated with integral coffee brew. Integral coffee brew reduced the obesity in the rats receiving hyperlipidemic diet, but the same effect did not occur with the decaffeinated types.
