Data are the mean ± SEM. Values significantly different from those obtained in the group of rats fed a chow diet (REF) are indicated by * (p < 0.05) and ** (p < 0.01). Data measured in the group of rats treated with ZD7114 (CAF-ZD) and significantly different from those in the group of rats fed a cafeteria diet (CAF) are shown by + (p < 0.05) and ++ (p < 0.05). Fatty acids representing more than 1% in at least one group are presented.
