家园 越扯越歪了

中国人乳腺癌发病率以前一直低于西方,近年因为饮食结构靠近西方等原因,乳腺癌发生率才逐年升高接近西方。

素食只会减少乳腺癌发病率好不好?!

家园 这。。。肉消费水平会饱和的吧?

如果中国人在2020年能以1万-1万5千美元的人均GDP,达到人均GDP4万美元国家的吃肉水平,那可真要偷着乐了。。。

人均1万和人均4万的国家,人均肉消耗水平恐怕真差不多。

当然粮食严重不能自己和保护市场的国家恐怕除外。

家园 说得对

有些人对美国盲目崇拜到了一定要学美国吃成猪,吃出病还坚持不懈。

家园 现在正在迪士尼感受西方的丰乳肥臀

就在想他们的脚和膝关节怎么承受这样恐怖的身体。

让他们主动改变是不可能了,不过单从如何减轻骨骼肌肉疼痛这个角度来看,里面一定有很多商业机会,希望有基础的人抓住吧。

家园 所谓继续摸着石头过河的说法便是

还没有认准了一条道走到黑。

家园 他到处宣传这个观点,是犯傻中心线还是故意

您这是啥算法,倍增是收入,不是猪肉

家园 对美国盲目崇拜到了一定要学美国吃成猪,吃出病还坚持不懈
家园 蛋白质的热量是最少的。

你的概念不正确。

家园 你这个才歪了

中国的乳腺癌和西方的乳腺癌不一样,中国人绝经前乳腺癌多,西方绝经后乳腺癌多,这种乳腺癌的发病机理不一样,与饮食关系很小。

家园 日本人以鱼为主,猪肉确实吃的少

而且人家卖东西已经给你算好了没人的消耗量,是按照人份卖东西。

家园 哦,那请麻烦解读一下这个研究的意思吧

Abstract

The association of breast cancer with dietary patterns such as a western diet has not been studied in Asian women. We examined this among Shanghai Breast Cancer Study participants. Cases were of ages 25 to 64 years, diagnosed 08/1996-03/1998, and identified through a rapid case ascertainment system supplemented by the Shanghai Cancer Registry. Controls, selected from the general population of urban Shanghai, were frequency matched to cases by 5-year age group. Participants provided information on diet, lifestyle, and reproductive factors. In principal component analysis among 1,556 controls, two patterns emerged: a "vegetable-soy" pattern (tofu, cauliflower, beans, bean sprouts, green leafy vegetables) and a "meat-sweet" pattern (shrimp, chicken, beef, pork, candy, desserts). In adjusted unconditional logistic regression analyses including 1,446 cases and 1,549 controls with complete covariate data, risk was not associated with the vegetable-soy pattern. It was associated with the meat-sweet pattern (4th versus 1st quartile: odds ratio, 1.3; 95% confidence interval, 1.0-1.7; P(trend) = 0.03), but only in postmenopausal women, specifically among those with estrogen receptor-positive tumors (4th versus 1st quartile: odds ratio, 1.9; 95% confidence interval, 1.1-3.3; P(trend) = 0.03). Our findings indicate that a western diet increases breast cancer risk in postmenopausal Chinese women. They also suggest the value of quantifying aggregate risk for common combinations of foods.

再看一下这个流行病学调查研究的数据(Cancer Causes Control. 2010 Nov;21(11):1777-85. Recent trends and patterns in breast cancer incidence among Eastern and Southeastern Asian women.Shin HR, Joubert C, Boniol M, et al.)吧:

年龄20–34、35–49、50–69和70岁以上几个年龄段的乳腺癌发病率在中国农村(嘉善、启东)分别为每十万妇女2.4、27.3、32.2、23.3,在上海分别为4.9、64.7、92.2、96.6。你觉得这个数据可以说明中国乳腺癌到底是绝经前多还是绝经后多吗?可以说明西方生活方式对中国乳腺癌的影响吗?

你还可以去搜几篇关于豆制品或大豆异黄酮对乳腺癌患者预后影响的文章,看看究竟饮食和乳腺癌有没有关系,再来这里讨论,OK?

家园 乳腺癌的危险因素如下:

Factors that are associated with an increased risk of breast cancer include:

1.Being female. Women are much more likely than men are to develop breast cancer.

2.Increasing age. Your risk of breast cancer increases as you age. Women older than 55 have a greater risk than do younger women.

3.A personal history of breast cancer. If you've had breast cancer in one breast, you have an increased risk of developing cancer in the other breast.

4.A family history of breast cancer. If you have a mother, sister or daughter with breast cancer, you have a greater chance of being diagnosed with breast cancer. Still, the majority of people diagnosed with breast cancer have no family history of the disease.

Inherited genes that increase cancer risk. Certain gene mutations that increase the risk of breast cancer can be passed from parents to children. The most common gene mutations are referred to as BRCA1 and BRCA2. These genes can greatly increase your risk of breast cancer and other cancers, but they don't make cancer inevitable.

5.Radiation exposure. If you received radiation treatments to your chest as a child or young adult, you're more likely to develop breast cancer later in life.

6.Obesity. Being overweight or obese increases your risk of breast cancer because fat tissue produces estrogen that may help fuel certain cancers.

7.Beginning your period at a younger age. Beginning your period before age 12 increases your risk of breast cancer.

8.Beginning menopause at an older age. If you began menopause after age 55, you're more likely to develop breast cancer.

9.Having your first child at an older age. Women who give birth to their first child after age 35 may have an increased risk of breast cancer.

10.Postmenopausal hormone therapy. Women who take hormone therapy medications that combine estrogen and progesterone to treat the signs and symptoms of menopause have an increased risk of breast cancer.

11.Drinking alcohol. Drinking alcohol increases the risk of breast cancer. Experts recommend no more than one alcoholic beverage a day for women.

这是目前教科书和医生公认的因素,个别论文的东西,在循证医学上,证据级别低。

家园 哦,一会说中国人和西方人不同

一会又拿西方人的结论来说这是共识。兄弟,这种玩法不成啊。我拿出来的可是基于亚洲/中国人的数据哦。

要说循证医学证据等级,在这里根本是牛头不对马嘴啊。在病因和危险因素分析上,分析性流行病学研究是主要的方法,什么RCT、荟萃分析,这里基本用不上啊,何来循证医学证据等级呢?

家园 意思没表达清楚,其实我说的是同时会摄入更多的热量
家园 你好像重新发明了一次《XX党宣言》,英雄所见略同

看来你和马克思的英雄所见略同。

强制公债,是马克思在《XX党宣言》中提到的措施。

“用累进税、高额遗产税、取消旁系亲属继承权、强制公债等来限制私有制”
