6-n-propyltiouracil (PROP) taster status in Brazilian adults
نویسنده
چکیده
Taste sensitivity to the bitter compound 6-n-propylthiouracil (PROP) is a genetic trait present in 70% of the population, and it is sensitive even at low concentrations of the compound (FOX, 1932). PROP tasters have a higher density of fungiform papillae and tend to perceive a wide variety of compounds, such as caffeine, sucrose, pepper, and fat with greater intensity (TEPPER, 2008; TEPPER; CHRISTENSEN; CAO, 2001).

First objective evaluation of taste sensitivity to 6-n-propylthiouracil (PROP), a paradigm gustatory stimulus in humans
Practical and reliable methods for the objective measure of taste function are critically important for studying eating behavior and taste function impairment. Here, we present direct measures of human gustatory response to a prototypical bitter compound, 6-n-propyltiouracil (PROP), obtained by electrophysiological recordings from the tongue of subjects who were classified for taster status and...

BACKGROUND Sensitivity to the bitter compound 6-n-propylthiouracil (PROP) is genetically mediated. Sensitivity to PROP has been associated with weight status in both adults and children. OBJECTIVE To determine whether there is an association between PROP sensitivity and BMI in low-income children of diverse race/ethnicity, among whom there is a high prevalence of obesity. METHODS AND PROCED...

OBJECTIVE The aim of this study was to investigate the relationship of taster status with taste detection and recognition thresholds for sucrose and quinine. DESIGN Sixty-nine subjects (35 men and 34 women; mean age, 23.9+/-1.2 years) were included. Stimulus fluids were prepared, one each for phenylthiocarbamide (PTC), 6-n-propylthiouracil (PROP), sucrose and quinine HCl. In each series, succ...
متن کاملGenetic taste responses to 6-n-propylthiouracil among adults: a screening tool for epidemiological studies.
Genetically mediated taste responsiveness to 6-n-propylthiouracil (PROP) has been linked to reduced acceptance of some bitter foods. In this community-based study male (n = 364) and female (n = 378) adults enrolled in a self-help dietary intervention trial were screened for PROP taster status. Respondents, aged 18--70 years, were mailed filter papers impregnated with PROP or with aspartame solu...

OBJECTIVES Eating behaviors and obesity are complex phenotypes influenced by genes and the environment, but few studies have investigated the interaction of these two variables. The purpose of this study was to use a gene-environment interaction model to test for differences in children's food acceptance and body weights. DESIGN AND METHODS Inherited ability to taste 6-n-propylthiouracil (PRO...
