Abstract:
1. When gastrointestinal transit and emptying of intraluminal contents were studied using a radioactive tracer marker [( 14C]PEG-4000), the fastest gastric transit and the slowest overall transit time were observed in female Wistar rats (1-3 months old) after they were fed a cafeteria diet (a hypercaloric diet). 2. The small intestine length of cafeteria fed rats was higher than lean rats, whereas the stomach and large bowel length showed no difference between cafeteria and lean rats. 3. A state of mild obesity was obtained after rats were fed a cafeteria diet. This obesity was demonstrated by the highest body weight and the highest gain of white adipose tissue in rats fed a cafeteria diet.
