用＂饥饿＂来治疗肿瘤? 一篇在顶级医学杂志发表的论文
北美愚医 (2017-03-02 10:44:51) 评论 (11)近年来，有关肥胖和肿瘤的关系研究得越来越多。比如乳腺癌 http://blog.wenxuecity.com/myblog/69489/201612/1618849.html ，肠癌，子宫内膜癌，
有人尝试用改变饮食习惯和结构的方式来治疗癌症。
那么肥胖和血液肿瘤有相关性吗? 在2007年发表在权威的《临床肿瘤杂志》Journal of Clinical Oncology 上，一组研究人员收集了从1988-1995年的343例肥胖，
有趣的是，最近一群在德州（UT Southwestern Medical Center) 的华人学者，在顶级医学刋物巜Nature Medicine》上发表了一篇用饥饿(fasting)
研究者制造了几个老鼠的急性白血病模型，
研究发现，间隙性一天禁食和一天进食，
看来，形势逼人，又多了一个与饮食/肥胖和肿瘤关系的模型！

应该说，这个重大研究目前仅在动物模型阶段。在人体呢? 大家去推测吧。

长知识。谢谢！
回复 '泥中隐士' 的评论 : 你说的很有道理。毕竟动物实验和人体的差异太大了。
截断肿瘤的营养不是新的想法。问题是怎样才能做到？靠吃一天饿一天？正常人一天得吃三顿饭，断一顿都饿的慌。还是想别的办法吧。
回复 '池上草堂' 的评论 : 非常感谢，很好的资料来源。
回复 'MoatCity' 的评论 : 谢谢你的评论
回复 'jyx-003' 的评论 : 我把原文复制过来：Strikingly, a regimen consisting of six cycles of 1 d of fasting, followed by 1 d of feeding,
什么是“间隙性一天禁食和一天进食，”？
Honestly how many fat centenarians have you seen? Almost all the people who lived above 100 years have been thin. Hiking with a Nurse Practitioner, started talking about Hep-C treatment, and how effective the new drugs are, she said that Hep-C is the major cause of liver transplant, now with the new drug, it won't be any longer. Then she asked me about the 2nd cause, I said Alcohol, she said NO, it is fatty liver.
Thanks for sharing, one more reason to keep the new year resolution of dropping weight, 2 LB so far, and 5 more pounds to go!
Many years ago, scientists believe sugar is the only source that cancer cell can use as energy. (To starve a tumor from MIT, http://news.mit.edu/2010/cancer-metabolism-0406). The reason behind ketogenic diet is to eliminate any kind of sugar intake.
Recently, MIT have two articles about how cancer cell can use other substance as energy. (How cancer cells get by on a starvation diet from MIT, http://news.mit.edu/2011/cancer-metabolism-1121; and How cancer cells fuel their growth from MIT, http://news.mit.edu/2016/how-cancer-cells-fuel-their-growth-0307).
According to this article, low calorie fasting does help to kill cancer cell (Fasting-like diet turns the immune system against cancer, http://news.usc.edu/103972/fasting-like-diet-turns-the-immune-system-against-cancer/)
Hope this information helps.
