Referral of retronasal odors to the mouth is a fundamental phenomenon of flavor perception. A previous study from this laboratory provided evidence that, contrary to prior speculation, taste rather than touch was the primary factor in retronasal odor referral. The present study further investigated this question by studying the role of congruency between taste and odor on retronasal odor referr...

Nutrient deprivation can lead to dramatic changes in feeding behavior, including acceptance of foods that are normally rejected. In flies, this behavioral shift depends in part on reciprocal sensitization and desensitization of sweet and bitter taste, respectively. However, the mechanisms for bitter taste modulation remain unclear. Here, we identify a set of octopaminergic/tyraminergic neurons,...

We test for the long-term impact of experiencing “prosperity in youth” (PIY) on nontraditional category consumption. Using unique twenty-year panel data of individuals from nine Chinese provinces with varying levels of per-capita GDP and rates of per-capita GDP growth, we find robust evidence for the PIY effect. We find both a direct effect of one’s own prosperity and an indirect effect of the ...

People vary in their habitual diet and also in their chemosensory abilities. In this study, we examined whether consumption of a Western-style diet, rich in saturated fat and added sugar, is associated with either poorer or different patterns of chemosensory perception, relative to people who consume a healthier diet. Participants were selected based on a food frequency questionnaire, which est...

STUDY OBJECTIVES To investigate whether exposure to tap water contaminated in a major river pollution incident with 2 ethyl 5,5 dimethyl 1,3 dioxane (EDD) and 2 ethyl 4 methyl 1,3 dioxolane (EMD) was associated with an increase of self reported symptoms. To assess the extent of association between noticing the water had an unusual taste or odour and self reported symptoms. DESIGN Retrospectiv...

We consider a decision maker who faces dynamic decision situations that involve intertemporal tradeoffs, as in consumption-savings problems, and who experiences taste shocks that are transient contingent on the state of the world. We axiomatize a recursive representation of choice over state contingent infinite horizon consumption problems, where uncertainty about consumption utilities depends ...

A study was conducted with staff at a fly-in/fly-out mine camp to determine the: hydration knowledge, perceptions and behaviours; hydration status and needs; and perceived taste of potable water. A structured questionnaire was used to survey the self-reported hydration behaviour, knowledge and perception of. The study of the hydration status and needs of day shift staff while at the residential...

Heroin addicts consume large quantities of refined sugars. This study investigated the effect of opiate use and antagonism on sweet taste in opiate-maintained drug users and detoxified former chronic opiate users, using a within-subject design. Seven opiate users received methadone and seven buprenorphine maintenance. Six detoxified subjects received naltrexone. Sucrose recognition thresholds a...

In Latin America, pulse consumption ranges from 1 kg/capita per year (Argentina) to 25 kg/capita per year (Nicaragua). Common beans account for 87 % of the total. The differences between countries, regions or groups of population within the same country can be explained by the following factors: (1) beans are very nutritious; (2) beans and maize are traditional foods and the habit of consuming ...
