Effects of consumption of acerola, cashew and guava by-products on adiposity and redox homeostasis of adipose tissue in obese rats

Summary Background Fruit by-products contain phytochemicals, fibers and other components that can improve the redox imbalance of obesity. Objective The objective was to evaluate the effects of consumption of by-products of acerola, cashew and guava on the adiposity and redox homeostasis of adipose tissue in obese rats. Methods The animals were separated into 5 groups, control (CTL), high fat (HF), HF supplemented with acerola (HFA), cashew (HFC) and guava (HFG). Results Thiol quantification, lipid profile, catalase (CAT) and glutathione peroxidase (GPX) test were performed. TGL and VLDL levels were increased in HF group, and the treated groups did not change the lipid profile. CAT activity was increased in HFA and HFG groups. HFA was able to reduce the weight of the subcutaneous cushion. Conclusion Treatment with fruit by-products did not alter weight gain, energy efficiency and body weight. Thus, the by-products of acerola and guava can be used as a sustainable alternative in the treatment of obesity.
