The highest causes of worldwide morbidity and mortality are cardiovascular diseases (CVD) that pose a major health concern affecting patients' quality of life. Pomegranate fruit contains unique compounds with various bioactivities and has been used as a powerful medicinal food in various illnesses, including CVD. Several trials confirmed the therapeutic impacts of its edible portion, but trials on pomegranate peel's impacts are fewer. Our aim was to evaluate the anti-inflammatory and antiatherogenic in vivo effects of pomegranate peel powder (PPP) in rats fed a high-fat diet (HFD). Twenty-eight albino rats were distributed among four groups: I (control), II (on HFD), III (on HFD and PPP 0.5?g/kg BW), and IV (on HFD and 1?g/kg BW). Blood samples were tested for interleukin-6 (IL-6), C-reactive protein (CRP), serum amyloid-A (SAA), total cholesterol (TC), high density lipoprotein cholesterol (HDL), and some primary biochemical parameters. HFD induced significant elevations in cholesterol and inflammatory markers as compared with controls. Nevertheless, HDL, alanine aminotransferase, creatinine, and albumin showed no change in all rats. In both PPP treatment groups, CRP and SAA levels were reduced significantly with significant decrease in TC. Samples of thoracic aorta from treatment groups showed a normal appearance and amelioration of subclinical atherosclerotic changes found in HFD group. PPP exhibited anti-inflammatory and antiatherogenic effects in comparison to HFD controls.
