A dietary study was conducted on board the USS CASIMIR PULASKI (SSBN 633) (Blue) during patrol. Sixteen crew member volunteers provided data concerning daily food intake, daily meal and snack distributions, weekly appetite changes, weekly food preferences, pure taste thresholds and body weight values. The eating patterns tended to change to a reduction in the number of regular meals and an incr...

Excessive dietary salt intake is related to cardiovascular morbidity and mortality. Although dietary salt restriction is essential, it is difficult to achieve because of salt palatability. However, the association between salt perception or salt eating habit and actual salt intake remains uncertain. In this study, we recruited 74 healthy young individuals. We investigated their salt-eating habi...

OBJECTIVE To prospectively evaluate the longitudinal subjective and objective outcomes of the microsurgical treatment of lingual nerve (LN) and inferior alveolar nerve (IAN) injury after third molar surgery. MATERIALS AND METHODS A 1-year longitudinal observational study was conducted on patients who received LN or IAN repair after third molar surgery-induced nerve injury. Subjective assessme...

BACKGROUND A positive effect of Endoscopic Sinus Surgery (ESS) as sole treatment on olfactory thresholds and sense of smell in patients with nasal polyposis has been questioned. The aim of this study was to test the hypothesis that ESS has a positive effect on sense of smell and olfactory threshold in nasal polyposis. METHODS Uncontrolled post-hoc analysis of a prospective study of 160 patien...

1. Twenty-eight pairs of monozygotic and eighteen pairs of dizygotic twins were tested for their ability to taste phenylthiocarbamide (P.T.C.) by the method of Harris & Kalmus (1949). 2. Much greater variance in threshold levels was detected within the DZ than within the MZ pairs and this confirms the genetic origin of most variation in ability to taste this substance. 3. Variance in threshold ...

Although human bitter taste perception is hypothesized to be a dietary adaptation, little is known about genetic signatures of selection and patterns of bitter taste perception variability in ethnically diverse populations with different diets, particularly from Africa. To better understand the genetic basis and evolutionary history of bitter taste sensitivity, we sequenced a 2,975 bp region en...

Mutational polymorphism in the TAS2R38 bitter taste receptor is a key determinant of threshold taste detection of isolated compounds, such as phenylthiocarbamide (PTC) and propylthiouracil (PROP), as well as complex orosensation-mediated traits such as diet choice and smoking habits. These relationships are accounted for, in part, by 2 common alleles differing in functionality, TAS2R38-PAV and ...

The chemical senses may represent the most fundamental integrative sensory modalities. For example, flavor perception is widely considered to be an integrative process whereby two distinct neural systems (olfactory and gustatory) are activated peripherally to give rise to a unitary oral sensation of flavor. Benefits of multimodal sensory integration in other modalities include increased sensiti...

The objective of this study was to examine the reliability of associations between fat taste, hunger, dietary fat intake, and body mass index (BMI). Detection thresholds for oleic acid (OA) were obtained during each of 7 consecutive visits using a modified staircase procedure. Participants were 48 (N = 17 male; N = 31 female) healthy adults (mean age: 28.5 ± 10.4 years) with BMI's ranging from ...
