English Abstract

Background: Differences in anthropometry and food acceptance among tasters and non-tasters of 6-n-propylthiouracil has been well studied in Western countries. However, reports on this issue from Asian countries are still limited. Methods and Study Design: Healthy Japanese students attending Nara Women's University (n=153) were recruited and classified into 3 groups based on taste sensitivity to a 0.32 mM 6-n-propylthiouracil solution as scored on a labeled magnitude scale. Accordingly, the study population consisted of 34 non-tasters, 78 medium-tasters, and 41 super-tasters. Self-reported food intake was assessed using a food frequency questionnaire. Self-reported food preferences were established using a food checklist listing 63 food items. Results: Although subjects in the 6-n-propylthiouracil non-taster group showed a significantly higher body height and weight than subjects in the taster groups, BMI was comparable among three groups. Intakes of calories, 3 macronutrients, β-carotene and vitamin C did not differ significantly between groups, but the intake of green and yellow vegetables was significantly lower in the taster groups. Among the 5 factors defined by a factor analysis performed with 277 age- and BMI-matched Japanese female students, the taster groups showed a significantly reduced preference for green and cruciferous vegetables alone. Conclusions: To the best of our knowledge, this is the first comprehensive report investigating associations between anthropometry, food intake, and food preference in relation to 6-n-propylthiouracil sensitivity in Asian countries. The effect of this tendency towards an aversion to vegetables including cruciferous ones among females on living a healthy life remains to be investigated.
