Distribution of taste thresholds for phenylthiocarbamide among different age groups in Turkey.

The relation between age and taste threshold in populations living both in Istanbul and Resadiye, a town located in eastern part of Turkey, was investigated. In Turkey the nontaster/taster ratio has been found lower than in the other countries of Europe and Asia (3 ,4 ,8 ,9). With aging the taste sensitivity of tasters does diminish. However, the differences in the taste threshold levels of nontasters, in different age groups, have been found as being statistically not significant.
