Over-consumption may be influenced by an individuals’ ability to detect a taste or their preference towards it. However, Malaysian data in this area is limited. This study aims to compare sucrose detection thresholds (SDT), sweet taste preferences (STP), and sugar consumption among normal weight and overweight/obese Malaysian Chinese adults.
This cross-sectional study recruited 44 Chinese participants aged 18-50 years, of normal weight (Nw : n=23, %F=12) and overweight/obese (Ow/ob: n=21, %F=10). SDT and SPT were assessed using constant stimuli method. SDT was determined using seven sucrose solutions of varying concentrations (0.73, 2.13, 4.27, 8.57, 17.1, 34.2, 102.6g/L.) To determine STP, participants rated their liking of five sucrose solutions (0, 5.13, 10.26, 20.62, and 41.25g/L) using the generalised labelled magnitude (gLMS) scales. Sugar consumption was estimated using a validated Malaysian added sugar food frequency questionnaire (FFQ).
Results & Discussion
Gender and age distribution were not significantly different between NW and Ow/ob groups (p>0.05). Despite lower median SDT in Ow/ob compared to Nw participants the difference was not significant (3.64(1.94)g/L vs 3.97(16.31)g/L, p=0.860). Similarly, for STP, both Nw and Ow/ob groups expressed dislike for all sucrose concentrations except for plain water which Ow/ob group scored positively and with higher scores [-6(29)mm vs. -3(28)mm; p=0.694]. Sugar consumption did not vary significantly between Nw and Ow/ob groups [44(56)g/day vs. 33(37)g/day; p=0.390]. Both SDT (r=0.109, p=0.481) and STP (r<-0.058, p>0.191) were not significantly associated with sugar consumption. These results may be affected by the cross-sectional nature of the study.
Sucrose detection threshold (SDT) and sweet taste preference (STP), and sugar consumption did not differ among Malaysian Chinese adults varying in bodyweight status.
