Fatty junk food destroys the brain cells that control weight, leading to a vicious circle of obesity, scientists have revealed. 科学家通过研究揭示了垃圾食品对健康的危害:因为热量超标的垃圾食品会破坏大脑中控制体重的细胞,并且有可能引发出现肥胖症。
The findings may explain why it is so hard for fat people to shift the pounds.
这项研究还解释了为何胖人想要甩掉几斤肥肉是如此的困难。
Researchers fed rats what they described as a 'typical high-fat American diet' and found they had doubled their calorie intake three days later.
研究人员们用被称为是“非常典型的美式高热量食物”来饲养小白鼠,并且发现白鼠在三天之后的热量摄取量竟然增加了一倍。
Further study showed they also had an inflammation in the hypothalamus, the part of the brain containing neurons that control body weight.
进一步的研究表明,白鼠的大脑中的下丘脑出现了炎症的状况,这部分大脑的神经元具有控制体重的功能。
This inflammation stopped a few days later but then recurred after four weeks.
这样的炎症在几天之后便消失了,不过在四周之后又再一次复发。
Lead researcher Dr Joshua Thaler, of the Diabetes and Obesity Centre of Excellence at the University of Washington in Seattle, said scientists also detected a healing response to brain injury called gliosis.
