The researchers add that stress is also known to increase intake of salty foods. But in this study, the team did not find any GC receptors in taste buds associated with salty and sour tastes. Parker says this may be because stress could have an influence on salt taste processing in the brain. Taste buds are not only found on the tongue; they are also present in the gut and pancreas.
Though it has often been proposed that varying taste receptor genotypes could influence tasting ability, TAS2R38 is one of the only taste receptors shown to have this function.gain, however, correlates between TAS2R38 genotype and the taste of alcohol were not significant: the TAS2R38 genotype could not predict the intensity of alcohol bitterness (though PROP bitterness did correlate with alcohol bitterness).
