How smells and tastes feel different peoples?

The perception of tastes and odors is different from both different people and in different nations. For example, there is a substance that residents of different regions of the planet perceive completely differently, – phenylthicarbeamide (FTK). In different peoples, the proportion of people perceiving the taste of FTK as bitter is from 5% to 85%. These differences are presented on the map (darker areas – a higher proportion of people who feel the bitter taste of FTK). The feeling of taste or smell is determined by the presence and features of olfactory and taste receptors. A person has several hundreds of genes of such receptors, and each gene is found in different versions. Differences in the ability to feel the taste and smell bind initially with the ability to distinguish edible and dangerous food. Interestingly, peoples differ in the number of words denoting the presence of smell. For example, in the languages ​​of Eurasia, there are only two words for this: "smells" and "stinks", everyone else describes the smell as related to specific objects (floral smell, the smell of the sea and T.

NS.). And in Polynesia there are five such terms, each of which indicates an independent category of smells. Whether the differences in the ability to perceive smells and the corresponding genetic differences are not yet known. It is assumed that both cultural and biological differences in the perception of odors and taste at least partly are associated with adaptation to the living conditions and accessible sources of food.
