研究发现胖子的大脑比同龄瘦子的老10岁!

Human brains naturally shrink with age, but scientists are increasingly recognising that obesity - already linked to conditions such as diabetes, cancer and heart disease - may also affect the onset and progression of brain ageing.

我们的大脑自然地随着年龄的增长而萎缩，但科学家们越来越认识到，肥胖除了已知与如糖尿病、癌症和心脏疾病等多种疾病相关之外，也可能影响大脑老化的发生与进展。

In the study of people aged between 20 and 87, researchers looked at the impact of obesity on brain structure across the adult lifespan.

在对一组20岁到87岁的参与者的研究中，科学家观察了在整个成人寿命期限内，肥胖对大脑结构的影响。

Researchers divided the groups into two categories: lean and overweight, depending on whether their BMI was above or below 25. They found striking differences in the volume of white matter. Overweight individuals had a widespread reduction in white matter compared with lean people.

依据身体质量指数高于或低于25，研究员将参与者分成了两组：偏瘦组和超重组。他们发现两组的脑白质含量有惊人的区别。与偏瘦组相比，超重组的脑白质含量普遍都比较低。

The team then calculated how white matter volume related to age across the two groups. They discovered that an overweight person at 50 had a comparable white matter volume to a lean person aged 60.
