Was the belief among scientists for centuries that the human tongue can detect only four senses of taste: sweet, sour, salty and bitter, and then discovered a fifth sense of taste is desirable. Now, researchers identified the sense that were not known by the sense of taste fat.
Team of scientists has identified a U.S. chemical sense sixth in the taste buds on the tongue recognize the fat molecules, and found that the sensitivity varies between individuals.
This disclosure may help explain why some people's consumption of more fatty foods because they are less aware of the flavor during eating.
The researchers hope to take advantage of the possibility of such disclosure in the fight against obesity increase the sensitivity of the people of the fat in their food.
Regardless of the basic senses of taste, there are other aspects to the taste of food, in fact emitted from the smell and discovered the nose.
The team of scientists from the Faculty of Medicine at Washington University in St. Louis that people who have more sense of the future known as "CD 36" were better in detecting the presence of fat in food.
They found that the differences in the gene that produces a "C-. De 36" make people more or less sensitive to the presence of fat.
Said Ms. Nada Abu Murad who led the research that the "ultimate goal is to understand how it affects our perception of fat in the food on what foods we eat and the properties of the fat we consume. We have discovered a possible cause for this disparity individual in how people's sense of fat, and Snanajh in the future is to determine If our ability to detect fat in the diet affect of fat in earnings, and this will have a significant effect on obesity. "
The study, published in the Journal of Research of the fat that those who have half the gene, "CNN. De 36" were eight times less sensitive to the presence of fat.
It is believed that about 20% of people have a different form of the gene associated with the production of lower levels of sense receptor, which may mean they are less sensitive to the presence of fat in the food, and this may make them more prone to obesity.
The researcher again that keeps track of the results in laboratory animals, the diet rich in fat will lead to the production of less than "C-. De 36", and this in turn can make a person less sensitive to fat.
The results of the study assumes that people are obese may benefit less from the C protein. De 36, then it may seem logical that the amount of protein that make up can be modified by genetic structure of the person and the diets.
