Junk Food Damages Brain Cells

Friday, June 24, 2011
Experts in the United States once again to warn the danger habit of eating junk food regularly. According to the latest research, food with high fat content but zero nutritional value can damage cells in the brain that controls body weight, and trigger a cycle of obesity. These findings also explain why people who are overweight are so difficult to lose weight.

In its research, experts from the University of Washington gave the rats in laboratory with foods with a 'high-fat diet of the American people'. Only three days later, the mice are getting greedy and increase calorie intake until doubled.

Further examination showed that these mice also had inflammation of the hypothalamus, the brain part which consists of nerve cells that control body weight. Inflammation was stopped within a few days, but then 'relapse' again after four weeks later.

Dr. Joshua Thaler, expert and researcher of Diabetes and Obesity Center of Excellence at the University of Washington in Seattle, said the experts also detect the existence of a response to the recovery of brain injury called gliosis. Gliosis considered similar with the recovery of brain injury and specifically looked at the condition of nerve injury, such as stroke and multiple sclerosis. Researcher think that the gliosis that they see probably is response to a failure of protection. Researcher also detect any significant damage and loss of important nerve cells in controlling weight. The injury in the brain of mice may be a consequence of excessive consumption of junk food and this fact gives an explanation why the weight loss becomes very difficult for most of them are obese.
