Abstract

Abstract— Individual food preferences are crucial predictors of food intake and can be highly influenced by taste sensitivity and perception. It is well known that fruit and vegetables have a variety of tastes and are not only dominated by bitterness. This study aimed to investigate the relationship between taste sensitivity and fruit and vegetable intake. Sensitivity for three basic tastes (e.g sweet, sour, and bitter) was measured using the staircase method whereby individual's sensitivity to the bitter compound 6-n-propylthiouracil (PROP) known as PROP taster status was determined by PROP disc determination. Food frequency questionnaire (FFQ) was used to record the fruit and vegetable intake of subjects. All data were analysed either using one way ANOVA or Pearson correlation at 0.05 confidence level. A total of 80 respondents were involved in this study and it was discovered that among them, 2.5% were PROP nontasters (n=2), 42.5% were medium tasters (n=34), and 55.0% were supertasters (n=44). PROP supertasters were found to have higher sensitivity on bitterness, whereby supertasters had higher bitter intensity ratings (p<0.05) compared to nontasters and medium tasters. In terms of fruit and vegetable intake, the highest consumed fruit was banana while the highest consumed vegetable was onion. Except for onion (p=0.044), no significant difference (p>0.05) was obtained between PROP taster groups and fruit and vegetable intake. Pearson correlation indicated that sweet sensitivity was positively correlated with durian intake (r=0.305) whereas bitter sensitivity was positively correlated to the intake of long bean (r=0.221). No significant relationship was present between sour taste sensitivity on the fruit and vegetable intake.

Abstract

This study employed a cross-sectional design to investigate the interrelationships among eating behaviours (emotional, restrained, and external), Body Mass Index (BMI), perceived stress, and dysmenorrhea among university students. A total of 190 students from three higher education institutions in Kota Kinabalu were recruited via convenience sampling. Data collection was conducted using a self-administered questionnaire comprising sections on sociodemographic background, eating behaviours (DEBQ questionnaire), stress levels (PSS-10 instrument), dysmenorrhoea (WaLIDD score), and anthropometric measurements. Relationships among the variables were analysed using Pearson’s correlation test. The findings showed that most students exhibited external eating behaviours (55.3%), followed by restrained eating (32.1%) and emotional eating (12.6%), with mean±SD scores of 3.16±0.57, 2.84±0.83, and 2.63±0.73, respectively. Most students had a normal weight (60.5%), reported medium stress (80.5%), and experienced moderate dysmenorrhea (51.1%), with corresponding means of 22.31±4.40 kg/m² for BMI, 20.89±4.96 for perceived stress, and 5.93±2.59 for dysmenorrhea severity. The restrained eating was significantly correlated with BMI (r=0.320, p<0.001). No significant correlations were observed between BMI and emotional or external eating (p>0.05). Emotional and external eating behaviours were significantly correlated with perceived stress (r=0.227; r=0.183) and dysmenorrhoea severity (r=0.223; r=0.288), with all associations significant at p<0.05. In conclusion, the exploratory findings highlight interrelated associations among eating behaviours, BMI, perceived stress, and dysmenorrhea. The results suggest potential interactions between eating patterns and body composition, with menstrual discomfort and psychological stress possibly influencing eating behaviours. These findings underscore the need for integrated university-based programmes that promote mindful eating, stress management, and menstrual health to enhance students’ well-being and academic performance.
