Preference for sucralose across a range of concentrations was similar in male Long–Evans (LE) and Sprague–Dawley (SD) rats. Data are mean (±SEM) preference scores (sucralose intake divided by total fluid intake, expressed as percentages). (A) Prior to categorization as either SP or SA, the rats displayed a reduction in their preference for sucralose over water as the concentration of sucralose was increased. This effect was similar in LE and SD rats. (B) SP preferred sucralose over water at all concentrations. This preference for sucralose was greater in LE rats, relative to SD rats, at concentrations of sucralose ≥ 0.5 g/L. In contrast, SA displayed indifference to 0.01 g/L sucralose and preferred water over sucralose at concentrations of 0.25 g/L and higher. No strain differences were detected among SA. *LE and SD SP > LE and SD SA, Ps < 0.05. +LE SP > SD SP, Ps < 0.05.
