高蛋白饮食和寿命长短有关系吗

Research shows that a diet high in protein and low in carbohydrates can help shed pounds and normalize blood-glucose levels, improvements that lower the risk of diabetes and cardiovascular disease.

研究表明，含有高蛋白、低碳水化合物的饮食有助于减肥并能使血糖水平恢复正常，而血糖水平得到改善能降低糖尿病和心血管疾病的患病风险。

But will you live longer on a high-protein, low-carb diet? Two studies in the current edition of the scientific journal Cell Metabolism suggest the opposite. One involved an experiment conducted on mice, the other an 18-year study of humans who had divulged their dietary habits. Both studies found a strong association between longevity and a low-protein, high-carbohydrate diet, although the human study bore a twist: Beyond age 65, higher protein levels appeared to promote longevity.

但你会因为高蛋白、低碳饮食而活得更久吗？科学期刊《细胞代谢》(Cell Metabolism)本期上的两项研究认为答案是否定的。其中一则研究涉及对老鼠进行的一项试验，另一则项则对那些暴露自己饮食习惯的人进行了长达18年的研究。尽管针对人类进行的研究与最终的结论有些出入，即过了65岁以后，更高的蛋白水平似乎会延年益寿。但前述两项研究均发现：在长寿与高蛋白、低碳水化合物的饮食习惯之间存在着一种强烈的关联。

'Those high-protein diets were developed with a shortsighted vision,' said Valter D. Longo, a University of Southern California professor of gerontology and biological sciences and the lead author of the human study. 'On a high-protein, high-fat diet you can lose weight, but in the long run you may be hurting yourself.'
