RESUMO
This study aimed to assess the impact of jatobá pulp, in its fresh (FJ) and extruded (EJ) forms, on lipid metabolism and intestinal fermentation parameters in hamsters. In a 21-day experiment, we determined the parameters of the animal lipid metabolism and colonic production of short chain fatty acids in four different groups. Control (C), fresh pulp (FJ) and extruded pulp (EJ) were fed using hypercholesterolemic diets, and the reference (R) was fed using AIN93 meal. R and C diets contained cellulose, FJ and EJ were added by jatobá pulp as a fiber source. The results showed that FJ and EJ exhibited lower levels of triglycerides, total cholesterol, LDL-c, non-HDL-c serum levels, liver lipids, and liver weight compared to C. The EJ had higher bile acid excretion in stool than the C. EJ and FJ exhibited lower excreted fiber compared to R and C, implying greater fermentation. Furthermore, the production of short-chain fatty acids (SCFA) in the cecum of FJ and EJ animals exceeded that of the C. Acetic and propionic acids were more abundant in the FJ and EJ diets, with FJ producing more butyric acid than the other groups.In conclusion, jatobá pulp maintained at normal levels of total cholesterol, LDL and HDL-associated cholesterol, non-HDL cholesterol, and serum triglycerides, while also reducing the accumulation of hepatic lipids. Jatobá also promoted SCFA formation and fermentation, making it a valuable ingredient for preventing chronic diseases.
