【纽约中医论坛ATCMS首发】 据2018年9月6日今日美国报消息,美国国家老年学研究所等单位发表的动物实验研究表明,间歇性禁食(intermittent fasting)是延长老鼠寿命的有效方法。研究者比较了数百只雄性老鼠的饮食情况和寿命,发现每24小时进食一次的老鼠,比24小时随便吃的老鼠的寿命要长40%。这个结果还优于限食30%的老鼠,而且效果同饮食的种类无关。科学家们认为,间歇性禁食可能是一种健康的饮食方法,给身体一定的时间来清空堆积的垃圾,有利于吸收和代谢。 类似的人类研究也表明间歇性禁食是控制体重的较好方法,方式有多种,比如定期禁食24小时,或选择性禁食数天。在很多传统文化中,都有定期禁食的习惯,中医也有“辟谷”健身的说法。 解释禁食有益健康的一种假说是,人类在数万年的进化中已经习惯于间歇性禁食,因为在远古狩猎和觅食中,身边不可能总有充足的食物。只是在近百年,由于生产力和科技的进步,出现了食品的极大丰富,冰箱、速食、快餐等饮食方式让人们随时可餐。但人的机体还没有进化或适应连续多餐的习惯,于是出现了各种代谢疾病,如糖尿病、心脏病、癌症等。所以,食欲与长寿是一对矛盾,未来的“寿命”可成为一种选择,每个寻求健康之人都应在“食欲与饥饿和美食与长寿”之间找到一条适合自己的中庸之道。(李永明) 【下面是报告原文】 Study links intermittent fasting to longevity USA Today (9/6, Brown) reports a new study by the National Institute on Aging “suggests that intermittent fasting could be the key to longevity.” Scientists from the NIA, the University of Wisconsin-Madison, and the Pennington Biomedical Research Center “found that increasing time between meals improved the overall health of male mice and lengthened their lives compared to mice that ate more frequently.” The study also found the health benefits were seen “regardless of what the mice ate or how many calories they ate.” Researchers watched babies for expressions of pain. They also used a noninvasive device to measure oxygen level changes in their brain as a way of detecting which brain areas were activated by pain and the effect of the different types of pain relief. 【纽约中医论坛首发-纽约博客】 |
