Good Lifestyle

A new study can provide a context why it's more difficult for some people to start eatinghealthier foods, especially after years of eating unhealthy.

On this day and age, there are no foods that escape high calories and grease. After all, grocery shelves and restaurant menus are often saturated with these types of options. Nevertheless, those who have access to nutritious foods can sometimes be difficult to start eating them and regularly. New research, however, suggest that this challenge can be attributable to how the brain meets some foods. (In touch:21 best healthy cooking hacks of all time)

The study, which was published in the newspaperNatureI explored how to eat a high diet affects the brain and, finally, his desire to eat healthier foods. The researchers gave mice at the same time a large fat diet (HFD) and a standard diet (SD). On the other side of the board, the mice has stopped eating the SD after the HFD has been offered. But when the HFD was taken away, the mice strangely eaten very little SD. As a result, the mice lost weight. Even mice that were in the fasting groupbarely touched the SD during the feeding time.

However, game mice would take place when the HFD was supplied and even after 24 hours of HFD madness, the mice would be less inclined to return to the SD. This prompted scientists to record the activity of AGRPR neurons, which is a group of neurons thatEnergy balance control and become active when you are hungry. Scientists also followed the neurons of the dopamine of the average brain, which release the dopamine - the neurotransmitter that makes youfeel good.

What did they find? After eating the HFD, the miceexperienced a reduction in responses from both neurons groups when exposed to the SD. So so that neurons do not fully respond when the HFD has been offered. In other words, the mice found that the standard diet is less satisfying and less rewarding than higher food in calories.

Another interesting location was that after meeting with the withdrawal of HFD, which was the means of the imitation of scientists - their AGRPR neurons were so sensitive to the HFD they start to react even when the mice n 'were not hungry. The researchers propose that this activity could explain why high calorie foods seem so irresistible when we try to diet - our brain treats these foods as more rewarding and valuable, even when we do not necessarily hunger.
