肥胖可能加速大脑老化
身体组织每增加一磅多余的脂肪，大脑组织便会缩小一分。一项最新的研究将肥胖和神经组织损耗联系了起来。 肥胖的老年患者的大脑组织比体重正常的同龄人平均小8%，超重患者则小4%。这项发现可能暗示，超重或肥胖的老年人可能会增加患有老年痴呆症的风险。研究人员认为肥胖与污染、酒精和吸烟一样都是加速大脑老化的因素之一。根据美国国家健康统计中心的报告，美国人中有超过6000万人肥胖。
"According to the US News and World Report, a recent study has shown a link between obesity and the loss of neurological tissue. The brains of elderly patients who were obese had on average 8% less tissue than their trimmer counterparts. Overweight patients had brains lighter by about 4%. This could have implications for the onset of dementia illnesses such as Alzheimer's. Just one more risk factor to add to the growing body (no pun intended) of reasons to try and stay trim."
