共1篇文章Eat to Live

A meager diet may give you health and long life,but it's not much fun—and it might not even be necessary.We may be able to hang on to most of that youthful vigor even if we don't start to diet until old age.

Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks.The genetic rejuvenation won't reverse other damage caused by time for the mouse,but could help its liver metabolize drugs or get rid of toxins.

Spindler's team fed three mice a normal diet for their whole lives,and fed another three on half-rations.Three more mice were switched from the normal diet to half-feed for a month when they were34months old—equivalent to about70human years.

The researchers checked the activity of11,000genes from the mouse livers,and found that46changed with age in the normally fed mice.The changes were associated with things like inflammation and free radical production—probably bad news for mouse health.In the mice that had dieted all their lives,27of those46genes continued to behave like young genes.But the most surprising finding was that the mice that only started dieting in old age also benefited from70per cent of these gene changes.

“This is the first indication that thee effects kick in pretty quickly,”says Huber Warner from the National Institute on Aging near Washington,D.C.

No one yet knows if calorie restriction works in people as it does in mice,bus Spindler is hopeful.“There's attracting and tempting evidence out there that it will work,”he says.

If it does work in people,there might be good reasons for rejuvenating the liver.As we get older,out bodies are less efficient at metabolizing drugs,for example.A brief period of time of dieting,says Spindler,could be enough to make sure a drug is effective.

But Spindler isn't sure the trade-off is worth it.“The mice get less disease,they live longer but they're hungry,”he says.“Even seeing what a diet does,it's still hard to go to a restaurant and say:'I can only eat half of that'.”

Spindler hopes we soon won't need to diet at all.His company,Life Span Genetics in California,is looking for drugs that have the effects of calorie restriction.

为生存而食

本文中心：A meager不足的diet节食

A meager不足的diet节食may give you health and long life,but it’s not much fun娱乐—and it might not even be necessary.We may be able to hang on to保持住most of that youthful vigor活力even if we don’t start to diet until old age.

很有可能也没必要。即

但这并不有趣------很有可能也没必要。

粗茶淡饭或许能给你健康和长寿，但这并不有趣

便在年老以后才开始节食我们也能在很大程度上保持住青春活力。

，但是却有助于这些老鼠的肝脏对药物的新陈代谢和清除毒素。

The changes were associated with things like 症and free radical production 4—probably bad news for mouse health.In the mice that had dieted all their lives,27of those 46genes continued to behave like young genes.But the most surprising finding was that the mice that only started dieting in old age also benefited from 70per cent of these gene changes.

。而对于那些终身都在节食的老鼠来说，那46种基因中的27种仍然继续保持着青春活力。但是最令人吃惊的发现却是那些只是在老年时期节食的老鼠们受益于70%70%的基因变异。

"If it does work in people,there might be good reasons for rejuvenating the liver.As we get older,our bodies are less efficient at metabolizing drugs,for example.A brief period of time of dieting,says Spindler,could be enough to make sure a drug is effective.如果这确实也对人类有效如果这确实也对人类有效，，我们有理由相信肝脏也可能恢复活力我们有理由相信肝脏也可能恢复活力。

。举个例子，随着我们一天天衰老，我们的身体对药物的新陈代谢越来越没有效率。短时期内的节食，斯潘德尔说到，完全足以保证药效。

But Spindler isn’t sure the trade-off 交易is worth it,6“The mice get less disease,they live longer,but they’re hungry,”he says.“Even seeing what a diet does,it’s still hard to go to a restaurant and say”‘I can only eat half of that’.”
