RELATIONSHIP OF PROP (6-N-PROPYLTHIOURACIL) TASTER STATUS WITH THE BODY MASS INDEX AND FOOD PREFERENCES OF FILIPINO ADULTS

摘要

The study determined the 6-n-propylthiouracil (PROP) status of Filipino adults and how it relates to their body mass indices (BMI) and food preferences. Self-reported food preference checklists were administered to 100 male and female adults aged 18-60, classified according to BMI. Increasing concentrations of PROP and NaCl solutions were rated in labeled magnitude scale to establish the PROP taster status of the selected respondents. The Filipino adult respondents were composed of 12% nontasters, 45% medium tasters and 43% supertasters. No association (P > 0.05) between BMI and PROP taster status was found. Sweet-tasting foods were the most preferred and bitter-tasting foods were the least preferred within each taster status. Furthermore, medium tasters and supertasters had the highest acceptance for meats, fish and poultry, and least acceptance for beverages, which were mostly bitter. Decreased preferences for fats and oils, sugars and confectionery, and beverages were correlated (P < 0.05) with responsiveness to PROP.
