School of Allied Health, University of Connecticut, 358 Mansfield Rd, Box U 101, Storrs, CT 06269 2101, USA
Alcohol Clin Exp Res 28:1629-37. 2004..g., bitterness) and more positive (eg, sweetness) sensations from alcohol. We determined whether the TAS2R38 gene at 7q36 predicted PROP bitterness, alcohol sensation and use...
- Surveying food and beverage liking: a tool for epidemiological studies to connect chemosensation with health outcomesValerie B Duffy
Department of Allied Health Sciences, Allied Health Sciences, College of Agriculture and Natural Resources, University of Connecticut, Storrs, Connecticut 06269, USA
Ann N Y Acad Sci 1170:558-68. 2009..Hedonic measures appear to capture habitual intake of foods and beverages, are easy to implement in the field, and thus may increase understanding of how chemosensory variation modifies disease risk...
- Variation in oral sensation: implications for diet and healthValerie B Duffy
Department of Allied Health Sciences, University of Connecticut, Storrs, Connecticut 06269 2101, USA
Curr Opin Gastroenterol 23:171-7. 2007..Important advances in our understanding of how taste, smell and somatosensation contribute to oral sensation are reviewed and the nutritional and health implications associated with variation in oral sensation are discussed...
- Food preference questionnaire as a screening tool for assessing dietary risk of cardiovascular disease within health risk appraisalsValerie B Duffy
Department of Allied Health Sciences, School of Allied Health, University of Connecticut, Storrs 06269 2101, USA
J Am Diet Assoc 107:237-45. 2007..Because cognitive research suggests that recalling food likes/dislikes may be simpler and more accurate than recalling intake, we tested whether a preference measure was predictive of cardiovascular disease risk factors within an HRA...
- Oral sensory phenotype identifies level of sugar and fat required for maximal likingJohn E Hayes
Department of Allied Health Sciences, College of Agriculture and Natural Resources, University of Connecticut, United States
Physiol Behav 95:77-87. 2008..A high affinity for high sugar/high fat mixtures among oral phenotype subgroups has relevance for energy consumption and could explain the link previously observed between oral sensation and body weight...
- Supertasting and PROP bitterness depends on more than the TAS2R38 geneJohn E Hayes
Department of Nutritional Sciences, College of Agriculture and Natural Resources, University of Connecticut, Storrs, CT 06269 2101, USA
Chem Senses 33:255-65. 2008..Variability in receptor expression may explain attenuated bitterness-FP relationships. PROP bitterness does associate with heightened taste sensations (i.e., supertasting), but this is not due to TAS2R38 polymorphisms...
- Revisiting sugar-fat mixtures: sweetness and creaminess vary with phenotypic markers of oral sensationJohn E Hayes
Department of Nutritional Sciences, College of Agriculture and Natural Resources, University of Connecticut, KH 310, 358 Mansfield Road, Unit 2101, Storrs, CT 06269 2101, USA
Chem Senses 32:225-36. 2007..Taste phenotype effects on sweetness and creaminess likely involve differential taste, retronasal olfactory, and somatosensory contributions to these perceptual experiences...
- Allelic variation in TAS2R bitter receptor genes associates with variation in sensations from and ingestive behaviors toward common bitter beverages in adultsJohn E Hayes
Department of Food Science, College of Agricultural Sciences, The Pennsylvania State University, 220 Food Science Building, University Park, PA 16802, USA
Chem Senses 36:311-9. 2011..Studying perceptual and behavioral differences in vivo using real foods and beverages may potentially identify polymorphisms related to dietary behavior even in the absence of known ligands...

Department of Allied Health Sciences, College of Agriculture and Natural Resources, University of Connecticut, Storrs, CT 06269, United States
Physiol Behav 106:264-71. 2012..They also suggest this relationship is explained through lower affinity for vegetables and fruits and greater affinity for fat/sugar foods...
- Sweet and bitter tastes of alcoholic beverages mediate alcohol intake in of-age undergraduatesSarah A Lanier
Dietetics Program, School of Allied Health, University of Connecticut, CT 06269 2101, USA
Physiol Behav 83:821-31. 2005..The college environment may attenuate direct effects of PROP bitterness and intake. Here, PROP bitterness does not predict alcohol intake directly, but acts instead through sweet and bitter tastes of alcoholic beverages...

Department of Surgery, Wayne State University, Detroit, Michigan, USA
Dig Dis Sci 50:483-9. 2005..In the subset reporting vegetable intake, men who tasted PROP as more bitter consumed fewer vegetables. These preliminary findings suggest that taste genetics may influence colon cancer risk, possibly through intake of vegetables...
