Sex Differences in Taste Preference for Glucose and Saccharin Solutions

Taste preferences of mature male and female rats for caloric and noncaloric sweet solutions have been found to differ. Although females do not drink more water than males, they consume significantly greater quantities of a slightly sweet 3 percent glucose and a very sweet 0.25 percent saccharin solu...

Description
Summary:Taste preferences of mature male and female rats for caloric and noncaloric sweet solutions have been found to differ. Although females do not drink more water than males, they consume significantly greater quantities of a slightly sweet 3 percent glucose and a very sweet 0.25 percent saccharin solution. When given a choice, males switch their initial preference for a saccharin solution to a preference for a glucose solution after several days, while females maintain a preference for the saccharin solution. Females also prefer significantly higher concentrations of saccharin than males do.
