高蛋白饮食和寿命长短有关系吗

而在那些年龄为66岁及以上的受访者身上，事实证明情况正好相反：更高的蛋白质摄取量与更大的生存机会息息相关。老年病学者称，这个完全说得通，因为在衰老的身体内，吸收蛋白的能力似乎会减弱，这就可能需要更高的摄取量。

Even then, though, the takeaway is somewhat complicated. Americans tend to consume the bulk of their protein at dinner, and the body isn't always able to process an entire day's worth in one sitting, said Dr. Volpi, who wasn't involved in either study. 'It appears you can better use the protein you need if you distribute it across three meals, especially if you are a senior,' she said.

然而即便如此，有关蛋白质的摄取问题还是有些复杂。沃尔皮博士说，美国人倾向于在晚餐时进食他们一天中的大部分蛋白质，而人体并非总能一口气消化掉一整天的营养。她还说：“如果你能将蛋白质的摄取任务分配到一日三餐中，你似乎就能更好地利用所需的蛋白质，尤其当你是位老年人时，情况更是如此。”沃尔皮并未参与到上述的任何研究中。

In one study, 858 mice were fed one of 25 diets with differing ratios of protein to carbohydrates. Those that ate higher ratios of protein were leaner. But they didn't live as long. 'Median life span increased (by about 30%) from about 95 weeks to 125 weeks as the protein-to-carbohydrate ratio decreased,' said the study, conducted by researchers in Australia. 'Our results show that healthy aging is not achieved in mice fed high protein diets.'
