Scientists have found that Europeans have a heightened sensitivity to sweet in comparison to people in other parts of the world.
The results of this study are listed in the portal ScienceNOW, said lenta.ru.
The study consisted of two parts - an experimental and bioinformaticheskoy. During the first 144 volunteers of different nationalities were invited to evaluate the sweetness of sugar solutions in which the sucrose content varied from 0% to 4%.
It turned out that the greatest sensitivity to sweet depending on the availability of the genome tested two specific gene variants Tas1r3. This gene encodes a taste receptor responsible for the perception of sweet taste.
analysis of genetic data bases containing information on 1050 people from different countries, showed that the Europeans basically have two options Tas1r3. I come from Asia and the Middle East, sweet genes are represented much less. More rarely, the entire interest of scientists options Tas1r3 met Africans.
Scientists believe that the increased sensitivity to sweet had to be ancient inhabitants of Europe to survive. Sugar-containing products have very high calorie content, which is very important for the inhabitants of cold regions.
able to recognize the right foods canimprove the quality of diet. In most of the saharosoderzhaschih plants grow in the tropics and the south, so the residents of these latitudes do not necessarily have an increased sensitivity to sweet, believe the authors of the study.
