BACKGROUND: Food selection and ingestion both in humans and rodents, often is a critical factor in determining excess energy intake and its related disorders. METHODS: Two different concepts of high-fat diets were tested for their obesogenic effects in rats; in both cases, lipids constituted about 40% of their energy intake. The main difference with controls fed standard lab chow, was, precisely, the lipid content. Cafeteria diets (K) were self-selected diets devised to be desirable to the rats, mainly because of its diverse mix of tastes, particularly salty and sweet...

The knowledge base of cancer-related symptoms is increasing; yet, limited attention has been given to provide evidence on differences in the perception of cancer symptoms between ethnic groups, especially in the Hispanic Puerto Rican (PR) population. To examine whether there are significant differences in the severity, distress, interference, and frequency of cancer symptoms between island Hispanic PR and mainland non-Hispanic whites. In this secondary data analysis, data from 109 Hispanic PR was matched by age, gender and cancer diagnosis with data from non-Hispanic whites...

The capability of perceiving olive oils sensory defects and intensities plays a key role on olive oils quality grade classification since olive oils can only be classified as extra-virgin if no defect can be perceived by a human trained sensory panel. Otherwise, olive oils may be classified as virgin or lampante depending on the median intensity of the defect predominantly perceived and on the physicochemical levels. However, sensory analysis is time-consuming and requires an official sensory panel, which can only evaluate a low number of samples per day...

BACKGROUND: Genetics plays an important role in the susceptibility to sporadic colorectal cancer (CRC). In the last 10 years genome-wide association studies (GWAS) have identified over 40 independent low penetrance polymorphic variants. However, these loci only explain around 1‑4% of CRC heritability, highlighting the dire need of identifying novel risk loci. In this study, we focused our attention on the genetic variability of the TAS2R16 gene, encoding for one of the bitter taste receptors that selectively binds to salicin, a natural antipyretic that resembles aspirin...

Agriculture biotechnology is a promising tool for developing varieties with enhanced quality and quantity. Transgenic proteins expressed by genetically modified (GM) food crops improve crop characteristics like nutritional value, taste, and texture, and endow plants with resistance against fungus, pests, and insects. Despite such potential benefits, there are concerns regarding possible adverse effects of GM crops on human health, animals and the environment. Among the proposed guidelines for GM food safety testing-the weight-of-evidence approach proposed by the Codex Alimentarius Commission (ALINORM 03/34A) is the most recent...

T2R38 has been shown to be a specific bacterial detector implicated in innate immune defense mechanism of human upper airway. Several clinical studies have demonstrated that this receptor is associated with the development of chronic rhinosinusitis (CRS). T2R38 was previously reported to bind to homoserine lactones (HSL), quorum sensing molecules specific of Pseudomonas Aeruginosa and other gram negative species. Nevertheless, these bacteria are not the major pathogens found in CRS. Here we report on the identification of bacterial metabolites acting as new agonists of T2R38 based on a single cell calcium imaging study...

Evaluative conditioning (EC) procedures can be used to form and change attitudes toward a wide variety of objects. The current study examined the effects of a negative EC procedure on attitudes toward chocolate, and whether it influenced chocolate evaluation and consumption. Participants were randomly assigned to the experimental condition in which chocolate images were paired with negative stimuli, or the control condition in which chocolate images were randomly paired with positive stimuli (50%) and negative stimuli (50%)...

OBJECTIVES/HYPOTHESIS: Olfactory dysfunction is common among the general population, with chronic rhinosinusitis (CRS) as one of the leading causes. Patients affected by CRS often report changes in taste sensations; however, quantitative measurements have not been performed to date. Therefore, the present study aimed to investigate gustatory and olfactory function in CRS patients prior to and after multimodal treatment. STUDY DESIGN: Prospective cohort study. METHODS: Twenty-one patients suffering from CRS with nasal polyps (14 male, seven female) with a mean age of 48 ± 15 years were included in the study...

Two experiments investigated whether attentional bias modification can inoculate people to withstand exposure to real-world appetitive food cues, namely television advertisements for chocolate products. Using a modified dot probe task, undergraduate women were trained to direct their attention toward (attend) or away from (avoid) chocolate pictures. Experiment 1 (N = 178) consisted of one training session; Experiment 2 (N = 161) included 5 weekly sessions. Following training, participants viewed television advertisements of chocolate or control products...

Traditional methods of sensory testing focus on capturing information about multisensory perceptions, but do not necessarily measure emotions elicited by these food and beverages. The objective of this study was to develop an optimum model of predicting overall liking (rating) and preference (choice) based on taste intensity and evoked emotions. One hundred and two participants (51 females) were asked to taste water, sucrose, citric acid, salt, and caffeine solutions. Their emotional responses toward each sample were measured by a combination of a self-reported emotion questionnaire (EsSense25), facial expressions, and autonomic nervous system (ANS) responses...

INTRODUCTION: Kuṅkumādi Ghṛta (KG) is an Ayurvedic formulation commonly recommended in skin disorders, especially Mukhadūṣikā (Acne vulgaris). Kesara (stigma of Crocus sativus Linn.) is a prime ingredient in the formulation. However, due to high cost and increased adulteration in Kesara, 'Nāgakesara' (Mesua ferrea Linn.) is suggested by Ayurvedic experts as a substitute. Nāgakesara is relatively lower in cost and possesses similar therapeutic attributes to that of Kesara. Recent studies have established standard manufacturing procedures and clinical efficacies of Kesarayukta (with Kesara) Kuṅkumādi Ghṛta (KKG) and Nāgakesara yukta (with Nāgakesara) Kuṅkumādi Ghṛta (NKG) in Mukhadūṣikā...

PURPOSE: In 2015, a study identified 5-15-fold higher levels of formaldehyde emissions from an old-generation e-cigarette tested at 5.0 V compared to tobacco cigarettes. We set to replicate this study using the same e-cigarette equipment and e-liquid, while checking for the generation of dry puffs. DESIGN: Experienced e-cigarette users (n = 26) took 4 s puffs at different voltage settings and were asked to report the generation of dry puffs. Formaldehyde emissions were measured at both realistic and dry puff conditions...

Using dyadic analysis, this study examined whether emotion suppression is a valid mediator in the relationship between mood change following a stressful couple discussion and subsequent food intake among cohabiting couples. In a laboratory setting, 80 heterosexual couples were presented with a bogus taste test immediately after discussing aspects that they would like each other to change. Mood change, emotion suppression and appetite perceptions were self-reported using visual analogue scales, and BMI was calculated based on objective measures...

OBJECTIVES: This study aimed at analyzing the effect of the temporary removal of trigeminal dental afferents on electrogustometric thresholds (EGMt). MATERIAL AND METHODS: EGMt were measured in 300 healthy subjects randomized in three groups, in nine loci on the right and left side (RS, LS) of the tongue surface before and after anesthesia. Group IAN (n = 56 RS, n = 44 LS) received intraosseous local anesthesia of the inferior alveolar nerve (IAN). Group MdN received mandibular nerve (MdN) block targeting IAN before its entrance into the mandibular foramen (n = 60, RS, and n = 40, LS); group MxN receiving maxillary nerve (MxN) anesthesia (n = 56 RS and n = 44 LS) was the control group...

Introduction: The endocannabinoid system (ECS) plays an important role in food reward. For example, in humans, liking of palatable foods is assumed to be modulated by endocannabinoid activity. Studies in rodents suggest that the ECS also plays a role in sweet taste intensity perception, but it is unknown to what extent this can be extrapolated to humans. Therefore, this study aimed at elucidating whether Δ9-tetrahydrocannabinol (THC) or cannabidiol (CBD) affects sweet taste intensity perception and liking in humans, potentially resulting in alterations in food preferences...

Dorothy W S Kwok, Robert A Boakes
In a serial overshadowing procedure a target stimulus, A, is followed after an interval by a potentially interfering stimulus, B, and this is then followed by an unconditioned stimulus, US. Revusky (1977) proposed that the degree to which B overshadows conditioning of A depends on whether or not the two events take place in the same context. To test this proposal two experiments used a 1-trial long-delay conditioned taste aversion (CTA) procedure; sucrose served as the target taste (A) and dilute hydrochloric acid (HCl) as the overshadowing taste (B), with lithium chloride injection providing the US...

Many basic characteristics of gustatory neurons remain unknown, partly due to the absence of specific markers. Some neurons in the geniculate ganglion project to taste regions in the oral cavity, whereas others innervate the outer ear. We hypothesized that the transcription factor Phox2b would identify oral cavity-projecting neurons in the geniculate ganglion. To test this possibility, we characterized mice in which Phox2b-Cre mediated gene recombination labeled neurons with tdTomato. Nerve labeling revealed that all taste neurons projecting through the chorda tympani (27%) and greater superficial petrosal nerves (15%) expressed Phox2b during development, whereas non-oral somatosensory neurons (58%) in the geniculate ganglion did not...
