Sham-feeding sucrose or corn oil stimulates food intake in rats.
In separate experiments, rats with open gastric cannulas were sham-fed either 32% sucrose solution or 15% corn oil emulsion. The rats' cannulas were then closed, and food intake was measured for 2 h. Food intake was greater after sham-feeding either fluid than after tests when no fluid was available. These results suggest that the oral stimulation produced by ingestion of sweet or oily fluids can stimulate appetite in the rat.
