title: Salt taste threshold and salt good taste sensitivity in a community of students of the southern area of Puerto Rico.
abstract: Sodium appetite reflects the importance of sodium homeostasis. The sodium ion is one of the most important risk factors in the development of hypertension. Humans, for various reasons, seem to have a specific preference for salt which is consumed in excess of need and this has been characterized as an important contributor to hypertension. Salt intake is related to the salt taste sensitivity threshold and the salt good taste level. Gustatory sensibility responds to various physiological mechanisms and salt taste is directly modified by cultural and socio-economical factors. We measured the salt taste sensitivity threshold and salt good taste level of a young student population. Air popped popcorn sprayed with different Molar concentrations of salt where given to students to taste and a questionnaire to evaluate diet salt intake preferences. Both salt taste sensitivity threshold and salt good taste level graph patterns are different from each other. Salt taste sensitivity threshold has a bell shape distribution with different molar salt concentrations. The major tendency of the salt umbral sensitivity of our population was the 0.5 M concentration. Salt good taste level has an exponential shape distribution with different molar salt concentrations. The tendency for the good taste level of our population was 3 M. Smoking does not seem to modify the salt taste sensitivity thresholds or the salt good taste level graphs. Also, salt shaker use does not seem to modify salt taste sensitivity thresholds or salt good taste level graphs in our population. Salt taste sensitivity threshold is probably associated to morpho-physiological factors. Salt good taste level is mainly associated with the cultural environment. The majority of subjects have a tendency to prefer foods with higher concentrations of salt increasing the possibility of exposure to the salt intake risk factor.
