  • Data are means ± SE. C-LF and C-HF, control groups fed a low-fat or high-fat diet, respectively; RF-LF and RF-HF, RF groups consuming a low-fat or high-fat diet, respectively. Within controls or RF groups, statistical differences between groups consuming a low-fat or high-fat diets are indicated as follows:
