Why do we like the sweet taste?

Those who are trying to lose weight will know that one of the first things you should do is let the sweet. And probably, the waiver of cakes, pies, ice cream or chocolate is what most costs.

 This is because the body has a special ability to recognize sugars and has a weakness for this flavor, which is usually done with fattening calorie products. The finding by a team of researchers from the Monell Chemical Senses Center in Philadelphia (USA), with your new mechanisms by which the body detects these flavors, could help 'fool' the body and avoid the extra kilos more.

So far, science knew that the T1R2 + T1R3 receptors were those who allowed the taste cells located in the mouth detect sweet compounds all-natural sugars, sweeteners, fructose and sucrose. However, in a study with mice was not all that taste detection could be explained with these receptors, as when one of them was suppressed rodents were able to continue to recognize the sweetness.

Researchers have delved into this issue and found, as published this week in 'Proceedings of the National Academy of Sciences' (PNAS), which together with these sweet receptor proteins, the body uses other sensors found in the intestine and in the pancreas and, in addition to detecting the sugars are responsible for absorbing and regulating blood glucose levels.

 "Detecting the sweetness of sugars and sweeteners is one of the most important functions of taste cells. If we did not recognize this flavor never satiate us and we would always be hungry. working with mice have discovered that in addition to the taste buds there are other guidelines for which the body senses glucose and other sugars, "explains Margolskee, adding that" finding nutritious sources of sugars is of vital importance to humans and animals, so the body has developed several mechanisms to detect ".

The problem, according to this expert, is that "in western countries eat too much food and very hot, so many people are overfed. "

Efficiently to limit this excessive consumption "we need to better understand how our body recognizes and metabolizes the sugars. To meet our need for sugar without exceeding calorie we must learn to 'trick' the body and give 'pig in a poke', ie products identified as the digestive system but not as sweet calories. And so, we must activate all the channels that are used to detect sugars and deceive everyone. A difficult mission in which we have to keep investigating, "said the expert .

As acknowledged by the authors of the investigation, "the process of recognition of sweet and all the factors involved in it is still not well understood. "

  1. This was an interesting read. Keep them coming!

  2. hmm, pretty interesting. What about spicy food then?

  3. Sugar is easy to avoid. It's the other foods that turn to sugar (carbohydrates) that are the big problem.

  4. sweet is an acquired taste. If you remove sugar from your diet. you wont like it as much later on.

  5. Very interesting post. I learned something from this.

    Thank you for sharing, and keep 'em coming! :)
