俗话说：“病从口入”，饮食和疾病的关系早已在医学研究中得到了证实，许多我们每天都吃的东西，恰恰是被忽视了的致癌物质，如果不多加小心，毒素日积月累，所造成的严重后果常常是难以预料的。
茶垢。有人认为， 茶垢是茶水长期沉积形成的，对身体无害，平时很少去洗，其实这是错误的。茶垢中含有镉、铅、汞、砷等多种有害金属和某些致癌物质，如亚硝酸盐等，可导致肾脏、肝脏、胃肠等器官发生病变。
水果中烂掉的部分。水果腐烂后，微生物在代谢过程中会产生各种有害物质，特别是真菌的繁殖加快。有些真菌具有致癌作用，可以从腐烂部分通过果汁向未腐烂部分扩散。所以，尽管去除了腐烂部分，剩下的水果仍然不能吃。
用报纸包的食品。油墨中含有一种叫做多氯联苯的有毒物质，它的化学结构跟农药差不多。如果用报纸包食品，它就会渗到食品上，然后随食物进入人体。人体内多氯联苯的储存量达到0.5—2克时会引发中毒。轻者眼皮红肿、手掌出汗、全身起红疙瘩；重者恶心呕吐、肝功能异常、肌肉酸痛、咳嗽不止，甚至导致死亡。
霉变的大米、花生和玉米。其中含有黄曲霉素，是目前世界上公认的强致癌物质，容易引起肝癌和食道癌。有人以为，多洗几次或高温消毒就能去除有毒物质，其实黄曲霉素一旦污染食物，是很难彻底清除的。
碱性食品中的味精。味精遇碱性食品会变成谷氨酸二钠，使其失去鲜味；当它被加热到120℃时，会变成致癌物质焦谷氨酸钠。因此，在有苏打、碱的食物中不宜放味精；做汤、菜时，应在起锅前放味精，避免长时间煎煮。
腐烂的白菜。腐烂和没腌透的白菜中，都含有致癌性亚硝酸盐。
烧烤食品。所有的烧烤食品中，都容易出现一种致癌能力相当强的物质———苯并芘，这和油炸食品中的油反复使用，所产生的是同一物质。
用卫生纸或毛巾擦过的水果。许多卫生纸的消毒不彻底，携带大肠杆菌、致病性化脓菌、真菌、乙肝病毒等；其中的填料和粉屑残留在餐具、水果上，也会对健康造成影响。
涂在筷子上的油漆。油漆筷子的使用现在仍然很普遍，但很多人都不知道，这些油漆中含有铅、苯等化学物质，常常随着油漆的剥落被我们吃进体内，造成一定的健康危害。
桌布上的有毒物质。很多饭店在桌子上铺的薄薄的塑料桌布是由聚氯乙烯制成的，含有毒的游离基，能通过餐具借食物进入体内，导致慢性中毒。所以，在外就餐时，不要将筷子直接放在铺有塑料薄膜的桌面上。
小心饮食中的致癌物

看了这帖子才知道自己吃得很不健康 
尤其是水果通常都是切掉烂了的那边就继续吃了
对于那些烧烤及油炸食物，很多时候会忍不住嘴馋，以后要收敛一些咯，哈！

Six good eating habits that will help prevent cancer
WASHINGTON (Medill News Service) -- Excess body weight, even just a little, increases your risk of cancer, according to a study released this week by the American Institute for Cancer Research. But staying active and following six rules for good eating can turn the odds back in your favor, researchers say.
Researchers analyzed more than 7,000 large-scale studies over five years and are now convinced, said Philip James, a member of the report's panel of experts, that excess body fat increases risks for cancer of the colon, kidney, pancreas, esophagus and uterus, as well as breast cancer in post-menopausal women.
But the report also found that "there are changes you can make in the way you live that will reduce your risk of getting cancer," said Jeffrey Prince, AICR's vice president for education.
Among the eight steps the 517-page report recommends are six that relate directly to diet. Top of that list: two-thirds of every meal should be made up of plant-based foods, such as whole grains, fruits, vegetables and beans.
Other dietary recommendations include limiting intake of "energy-dense foods," foods that contain high amounts of fat, sugar or calories, such as fried foods, hamburgers and soft drinks. Consumption of alcohol, red meat and processed meats were also linked to elevated cancer risk. The report advocates eating no more than 11 ounces of red meat per week, and no more than one alcoholic drink per day for women, and two per day for men.
The panel specifically advocated abstinence from all processed meats, such as bacon, ham and other lunchmeats. They were unable to find a level of consumption that could be considered safe.
In addition to dietary restrictions, the report also recommended being physically active at least 30 minutes every day. Tobacco should be avoided altogether.
Concerned, but willing to change?
In this year's "Facts vs. Fears Survey," an annual breakdown of Americans' health concerns also published by the AICR, more people (39%) listed cancer as their No. 1 health concern.
Yet despite those findings, and despite the researchers' confidence in their recommendations, it is unlikely people will change, said Edward Abramson, professor emeritus of psychology at California State University-Chico and author of "Body Intelligence," a guide to losing weight and eating well without strict dieting.
"I'm sure that there are a couple of people who would latch on and follow them," Abramson said. "But for most people, the immediate reward of having a high-calorie, sugary treat more than offsets the long-term reward of possibly avoiding cancer at some ill-defined point in the future."
"There's nothing intrinsically wrong with [the guidelines]," he said, "except for the fact that people typically don't live like that."
Arthur Frank, medical director of the George Washington University Weight Management Program in Washington, agreed.
"It's very difficult to change the way people eat," he said. "If it weren't, we wouldn't have an obesity epidemic."
The researchers say they understand the difficulty. A second report, to be released next fall, will contain information on how to help the public actually achieve the goals outlined in this year's study.
In the meantime, "Eat less and exercise more," Frank said. "Everything else is a variant of just that -- you cannot violate the laws of thermodynamics."
The American Institute for Cancer Research has released these eight guidelines for avoiding cancer. The last six are eating related:
1）Be as lean as possible within the normal range of body weight
2）Be physically active as part of everyday life
3）Limit consumption of "energy-dense foods," foods that are high in calories, fat and sugar. Avoid sugary drinks.
4）Eat mostly foods of plant origin, including fruits, vegetables, whole grains and beans
5）Limit intake of red meat and avoid processed meat
6）Limit alcoholic drinks to one per day for women, two per day for men
7）Limit consumption of salt. Avoid moldy grains or legumes
8）Aim to meet nutritional needs through diet alone, without dietary supplemen
