Why People Eat Foods Constantly Even If They Are Not Hungry-姉summer

Science Through experiment, researchers in United States University of Texas Southwestern Medical Center have found that a material called hunger hormone make the mice find food to eat under the case of not hungry. Researchers built two houses for mice, one is striped walls which placed delicious high-calorie food inside the cabin, the other is gray walls which placed small low-calorie foods. After repeated training, mice have remembered where the house for what it was. Then, the researchers feed the mice so that they choose a hut to enter. The results showed that mice injected the "hunger hormone" are more likely to enter the striped walls cabin, even if there is no food in the cabin. But mice which were not injected the "hunger hormone" showed no preference. Jeffrey Zigman, vice Professor of this experiment, said:" Our research showed that this hormone may affect associated with the consumption-related behavior, which led to over-eating." The words were quoted by Fun Science Site. Zigman considered that the "hunger hormone" may produce the extra desire for food." Mice’s behavior has nothing to eat food, just to get more pleasure." he explained. Mario Peirello, another charger of this study, said:"We believe that the hunger hormone would make mice go looking for high-calorie foods, because they remember how delicious it is. Even if there is no food inside, it does not matter, mice still believe it can cause some kind of pleasure associated with the existence of things." there are .mons in brain cells connected, hormone type and brain "pleasure center" between human and mouse. However, the "hunger hormone" is not the only reason for non-stop eating. Other factors may also cause people to over-eating. For example, the firs factor is gene. A gene called GAD2 was found by Imperial College London researchers in 2003, which easily lead to obesity. These genes will accelerate a neurotransmitter synthesis in the brain so as to stimulate people to eat. The next factor is the level of dopamine, a study published on Behavioral Neuroscience magazine in 2007 point that people with low levels of dopamine were more likely to seek pleasure and eat too much. Finally, the third reason is psychological factor. A .mon phenomenon is that a lot of frustrated people would eat large numbers of food. About the Author: 相关的主题文章:
