THE EFFECT OF DIETARY FAT LEVEL ON POSTPRANDIAL GASTROINTESTINAL BLOOD FLOW PATTERNS
Abstract
To establish the effects of dietary fat on splanchnic and peripheral blood flow patterns, electromagnetic blood flow probes were chronically implanted on the coeliac and cranial mesenteric arteries and the abdominal aorta of four male beagle dogs. The dogs were fed meals of three sizes containing three concentrations of fat. Blood flowrate in the three vessels was monitored, both at rest and running on a treadmill at moderate exercise. The combined flow of the coeliac and mesenteric arteries increased to a peak flow after eating. The velocity and time of peak flow were not affected by meal size or fat content, although the time of peak, flow was slightly delayed by exercise. The average splanchnic flow was unchanged by meal size, fat content, or exercise. Average abdominal aortic flow was unchanged by meal size or fat content, and was consistently increased by exercise regardless of diet regime.
