Research results have shown that when the vagus nerve is stimulated, dopamine is secreted and the desire for high-fat and high-sugar foods increases. / Photo = Clip Art Korea The reason why it is difficult to resist the temptation of high-fat and high-sugar foods has been revealed.
The U.S. Monell chemical sensory research team analyzed the signaling pathway between the intestines and the brain. The research team used cutting-edge neuroscience technology to manipulate the vagus nerve in a rat model and observe changes.
The research team analyzed that the vagus nerve, a signaling pathway between the intestines and the brain, stimulates the desire to eat high-fat and high-sugar foods. The vagus nerve transmits internal sensory information to the brain via nerve cells in the intestines, which creates an unconscious desire to eat fat and sugar.
As a result of animal experiments, when the vagus nerve was stimulated, neurons in the brain detected this, secreted dopamine, and increased the desire for fat and sugar. In particular, eating foods containing a combination of fat and sugar released a much larger amount of dopamine, leading to overeating.
Dr. Guillaume de Rattigue, who led the study, said, “The results of this study reveal why we overeat foods rich in fat and sugar,” and added, “For effective dieting, we need to find a way to overcome this unconscious desire.” said.
Meanwhile, the results of this study were recently published in ‘Cell Metabolism.’
