Experiment 2, Test series 1. Mean intakes (+SEM) of 8% fructose, 0.1% sucralose + 0.1% saccharin (SS), and water in 2-day, 2-bottle tests in CAST (left panel) and B6 mice (right panel). (Order of testing is from left to right in the panels.) In Tests 1 and 4, the mice were given the choice of fructose versus SS. In Test 2, the choice was fructose versus water and in Test 3, it was SS versus water. Numbers atop bars represent mean percent preference for that solution. Significant (P < 0.05) intake differences within the 2-bottle tests are indicated by an asterisk (*).
