Two distinct patterns of sweet taste liking have been described: one showing a
peak liking response in the mid-range of sucrose concentrations and the other
showing a monotonic liking response at progressively higher sucrose
concentrations. Classification of these patterns has been somewhat arbitrary. In
this report, we analyzed patterns of sweet taste liking in a pilot study with 26
adults including 14 women and 12 men, 32.6 ± 14.5 years of age with body mass
index 26.4 ± 5.1 kg/m² (mean ± SD). Sweet taste liking was measured for 10 levels
of sucrose solutions (0.035 M to 1.346 M). Participants rated their liking of
each solution using a visual analog scale with 0 indicating strongly disliking
and 100 strongly liking. The cluster analysis demonstrated two distinct groups:
13 liked relatively low sucrose concentrations and liked high sucrose
concentrations less, and 13 liked high sucrose concentrations greatly. If we use
the 0.598 M sucrose solution alone and a cutoff liking score of 50, we can
distinguish the two clusters with high sensitivity (100%) and specificity (100%).
If validated in additional studies, this simple tool may help us to better
understand eating behaviors and the impact of sweet taste liking on
nutrition-related disorders.
