Being overweight in middle-age makes the brain age by 10 years, research by the University of Cambridge has found. 据剑桥大学的一项研究发现，中年肥胖者的大脑会比他们实际年龄老10岁。 The study, which scanned 473 brains, found changes in the brain structure of overweight people which are normally seen in those far older. 通过对473个人进行脑部扫描，这项研究发现，超重人士，尤其是那些年老人士的大脑结构有所变化。 The volume of white matter - the tissue that connects areas of the brain and allows information to be communicated between regions - shrunk far more in those with a Body Mass Index above 25. Shrinkage of parts of the brain is associated with a higher risk of cognitive decline and dementia. 对于那些身体质量指数在25以上的人，脑白质（连接大脑各区域的组织,并允许各区域之间进行信息的传递）萎缩的更严重。而大脑的收缩，意味着具有认知衰退和痴呆的高风险。 |
