This study aims to determine the threshold of salt taste recognition and to evaluate differences by sex, age and body mass index (BMI) among a sample of Moroccan population.
A simple-blind experimental study was conducted among 201 healthy subjects to determine the threshold of salt taste recognition and to evaluate differences by sex, age and BMI among a sample of Moroccan population. The threshold of salt taste recognition was determined based on the validated the three alternatives forced choice method. A total of 11 prepared solutions of sodium chloride at different concentrations ranging from 0–500 mmol/L were used.
The average of the total population was 14.6 ± 10.9 mmol/L. And, 84% of the total population recognized the salt taste at the concentration of 15 mmol/L. Women participants detected the salt taste at a lower rate (53% versus 38% at 8 mmol/L, p = 0.02, in women and men, respectively). The mean values of the threshold among women was significantly lower (12.6 ± 8.1 mmol/L) compared to men (16.7 ± 12.8 mmol/L), p < 0.001. No statistical difference was obtained among either age groups or BMI categories.
The present study showed that the average threshold of salt taste recognition is high, and that it is even higher in men compared to women. At a community level, a progressive reduction of salt in food items is recommended.
