The R-index approach to the signal-detection P(A) index of sensitivity was used to measure taste sensitivity to NaCl solutions. The R-index is the predicted probability of the correct choice of a signal, for a given signal – noise pair. For flow-wise and sipwise presentation, R-indices did not fluctuate significantly, provided subjects could not see the stimuli yet to be presented, indicating a lack of systematic sensitivity drift. The simultaneous measurement of more than one signal strength with reference to a common noise stimulus was seen to be a viable and sensitive procedure. Comparison of flow-wise and sipwise presentation of stimuli using R-indices, indicated that the former elicited greater subject sensitivity to NaCl taste.

ABSTRACT Background Although salt taste preference is malleable in adults, no research to date has focused on children, whose dietary sodium intake exceeds recommended intake and whose salt taste preferences are elevated. Objective This proof-of-principle trial determined whether 8-wk exposure to low-sodium cereal (LSC) increased children's acceptance of its taste and changed their salty and sweet taste preferences. Methods Children (n = 39; ages 6–14 y; 67% female) were randomly assigned to ingest LSC or regular-sodium cereal (RSC) 4 times/wk for 8 wk. The cereals, similar in sugar (3 g/cup compared with 2 g/cup) and energy content (100 kcal/cup) yet different in sodium content (200 mg sodium/cup compared with 64 mg sodium/cup), were chosen based on taste evaluation by a panel of children. Mothers completed daily logs on children's cereal intake. At baseline and after the exposure period, taste tests determined which cereal children preferred and measured children's most preferred amount of salt (primary outcomes), and most preferred amount of sucrose and salt taste detection thresholds (secondary outcomes). Repeated measures ANOVAs were conducted on primary and secondary outcomes, and generalized estimating equations were conducted on amount of cereal ingested at home over time. Results Both treatment groups accepted and ate the assigned cereal throughout the 8-wk exposure. There were no group × time interactions in salt detection thresholds (P = 0.32) or amount of salt (P = 0.30) and sucrose (P = 0.77) most preferred, which were positively correlated (P = 0.001). At baseline and after the exposure, the majority in both groups preferred the taste of the RSC relative to LSC (P > 0.40). Conclusions Children showed no change in salt preference but readily ate the LSC for 8 consecutive weeks. Findings highlight the potential for reducing children's dietary salt intake by incorporating low-sodium foods in the home environment without more preferred higher-salt versions of these foods. This trial was registered at clinicaltrials.gov as NCT02909764.

Previous investigators have reported deficits in taste acuity in patients following radiation therapy for oropharyngeal cancer. In the present longitudinal study, 13 patients (mean age = 51.6 yrs) received conventional or hyperfractionated radiotherapy (63–76.8 Gy) for primary tumors of the oropharynx. One or both parotid glands and at least two-thirds of the tongue were included in the radiation field. Smell recognition and taste detection thresholds were determined at baseline, 1 month, 6 months, and 1 year post-radiation. Differences for smell recognition and the 4 taste qualities were assessed (independently) at the 4 time intervals, with a one-way ANOVA. Smell recognition was unaffected by radiation. There were significant elevations in thresholds for sweet (p < 0.005), salty (p < 0.005), bitter (p < 0.005), and sour (p< 0.001) during radiation therapy that were restored to baseline levels at 6 months and 1 year after radiation. This study demonstrated that radiation-induced taste deficits can be recovered by 6 months.

Abstract Taste perception has been reported to vary with changes in affective state. Distortions of taste perception, including blunted recognition thresholds, intensity and hedonic ratings have been identified in those suffering from depressive disorders. Serotonin is a key neurotransmitter implicated in the aetiology of anxiety and depression; systemic and peripheral manipulations of serotonin signalling have previously been shown to modulate taste detection. However, the specific effects of central serotonin function on taste processing have not been widely investigated. Here, in a double-blind placebo-controlled study, acute tryptophan depletion was used to investigate the effect of reduced central serotonin function on taste perception. 25 female participants aged 18-28 attended the laboratory on 2 occasions at least 1 week apart. On one visit they received a tryptophan depleting drink and on the other a control drink was administered. Approximately 6 hours after drink consumption they completed a taste perception task which measured detection thresholds and supra-threshold perceptions of the intensity and pleasantness of four basic tastes (sweet, sour, bitter and salt). While acutely reducing central levels of serotonin had no effect on the detection thresholds of sweet, bitter or sour tastes it significantly enhanced detection of salt. For supra-threshold stimuli, acutely reduced serotonin levels significantly enhanced the perceived intensity of both bitter and sour tastes and blunted pleasantness ratings of bitter quinine. These findings show manipulation of central serotonin levels can modulate taste perception and are consistent with previous reports that depletion of central serotonin levels enhances neural and behavioural responsiveness to aversive signals.
