中国茶叶抗癌效果排名，乌龙茶铁观音第一名

中国茶叶抗癌效果大排名

第1名：乌龙茶

第2名：普洱茶

第3名：红茶

第4名：绿茶

很多人都知道茶叶中的茶多酚可防癌，但你知道吗？不同的茶叶品种也具备不同的防癌效果。

南京市中医院肛肠科金黑鹰主任是茶多酚方面的研究专家，他表示，经过研究，抗癌效果排在第一位的是乌龙茶，即安溪铁观音、武夷岩茶等乌龙茶，其次是普洱茶，第三是红茶。

此外，科学家们也通过研究后发现，茶多酚中的主要成分EGCG是很多癌症的“克星”，特别是对子宫癌、皮肤癌、肺癌等有独特疗效。

01茶多酚中的有效抗癌成分被披露

金黑鹰主任，是南京遗传性家族肠癌的研究者之一。

他将人类的结肠癌基因移植到老鼠身上，很快，这些老鼠变得“奄奄一息”，成了结肠癌“患者”。

茶叶里有个茶多酚的主要成分，据说抗癌作用也主要集中在这个成分上，他将这种成分每天都注射到小老鼠体内，两个星期后，肿瘤的生长速度减缓，而且有明显缩小的趋势。

金黑鹰主任告诉记者，大家一直知道是茶多酚有抗癌效果，但究竟是茶多酚中的哪种成分有效呢？

后来，经过实验证明，是茶多酚中主要成分EGCG可以恢复正常细胞的秩序，破坏了肿瘤细胞，让肿瘤细胞凋亡加速。

国内还有专家研究认为，用绿茶或红茶处理动物可使实验动物的食道癌、胃癌或皮肤癌减少70%。

从这一系列的研究可以看出，EGCG成分确实起到了抗癌的作用。

02不同的茶品，防癌效果不同

金黑鹰主任告诉大家，其实，茶叶的品种不同，抗癌防癌的效果也是大相径庭的。

他坦言，如果将茶叶的抗癌防癌的功效进行排序的话，那么，排在第一位是乌龙茶，其次是普洱茶，第三是红茶，例如单丛红茶，第四是绿茶。

这是因为，发酵类的茶比不发酵的茶具有更多的抗癌防癌效果。

相比之下而言，乌龙茶、普洱茶就排名靠前，而绿茶则排名靠后。

他分析说，首先，茶多酚中的EGCG具有抗氧化的活性。其次，EGCG抑制对肿瘤具有促发作用的酶类的活性。

这些酶类包括蛋白质激酶C、鸟氨酸脱羧酶、环氧合酶和脂氧合酶等。第三，茶多酚可促进具抗癌活性的酶的活性。

这些酶类包括过氧化氢酶、谷胱甘肽-S转移酶等。第四，可以抵抗肿瘤增殖的活性。第五，经常饮茶的人可以增强免疫性。

据悉，有科学家曾用1.25g绿茶加100mL沸水的茶汤作为小鼠的唯一饮料，可使化学致癌物诱导的小鼠肺肿瘤减少36%～44%，使肿瘤的繁殖降低44%～60%。

红茶也具有同样效果，此外，用绿茶或红茶处理动物可使实验动物的食道癌、胃癌或皮肤癌减少70%。

03医生建议根据个人的口味选茶叶

记者问，根据医学专家和科学家们的研究结果，那么是不是建议大家只喝乌龙茶呢？

对此金黑鹰主任表示，虽然研究的结果是这样，大家还是得根据个人的口感和口味不同来选择茶叶。

04建议：泡茶后两小时内喝完

其实，现在有不少人喜欢出门前泡一大杯茶，然后喝掉一些，再往里添水，通常是从早喝到晚。

这样的做法健康吗？金黑鹰表示，一般来说，泡茶之后，两个小时之内，需要把茶喝完，如果还想喝就需要重新浸泡。

茶叶里具有很多抗氧化剂，而这些抗氧化剂是由很多不稳定的羟基构成的。

一般来说，这些成分不稳定，因此在浸泡两个小时之内，就应该将茶喝完，不然这些有效成分发生了变化，不仅可能不再具有抗癌防癌的效果，可能还会产生对身体不利的物质。

在金主任看来，泡茶的温度和杯具的选择也同样很重要。

泡茶的水尽量保证在80度左右为宜，超过80度，有的人甚至用100度的沸水泡茶，这样可能破坏茶里的有效成分。

另外，杯具的选择，最好选择紫砂壶，其次选择瓷器，或者玻璃杯等，最好不要选择不锈钢的保温杯具。

茶水和药物一起使用效果更好？

根据研究表示，如果茶水和抗肿瘤药一起服用效果更好。

看到这里，可能有人心中存疑，“不是说不能用茶叶水服药吗？”就这个话题也咨询了金主任了，他表示，这里说的同服，并不是指用茶叶水来服药。

这里的意思是指，如果肿瘤患者在进行抗肿瘤治疗的同时，也有喝茶的习惯的话，那么，抗癌的效果会事半功倍。

另外，专家还发现，在不需要任何节食、锻炼等手段，每天喝8-10克茶叶，12周内，仅茶叶自身作用减掉的脂肪约为3斤。

在日本、欧美国家所有减肥产品里，茶叶制品排名第一。

05小茶叶，大学问

1、日本对百岁老人长寿调查中发现，有四成百岁老人长寿诀窍是一生嗜茶如命，有八成百岁老人有饮茶习惯。

2、抗氧化试验证实，一杯茶300毫升，它的抗氧化功能相当于一瓶半的红葡萄酒，相当于12瓶的白葡萄酒，相当于12杯的啤酒，相当于4个苹果，相当于5只洋葱，相当于7杯的鲜橙汁。

3、据日本科研人员试验结果证实，茶多酚的抗衰老效果要比维生素E强18倍。

4、日本昭和大学的医学研究小组，在1毫升稀释至普通茶水的20分之1浓度的茶多酚溶液里放入10000个剧毒大肠杆菌0-157，五个小时后细菌全部死亡，一个都不剩。

5、喝茶会让你莫名其妙地开心。

茶中的氨基酸会促进多巴胺的大量分泌，而多巴胺是主导人体情感、愉悦感、性欲、瘾性等的物质。喝茶的愉悦感是不自主的，不受意念控制的。

China's tea anti-cancer effect ranking

No. 1: Oolong Tea

No. 2: Pu'er Tea

No. 3: Black tea

No. 4: Green tea

Many people know that the tea polyphenols in tea can prevent cancer, but did you know? Different tea varieties also have different anti-cancer effects.

The director of Jinheiying of the Anorectal Department of Nanjing Traditional Chinese Medicine Hospital is a research expert on tea polyphenols. He said that after research, the anti-cancer effect ranked first is oolong tea, namely Anxi Tieguanyin, Wuyi Yancha and other oolong teas, followed by Pu'er tea, the third is black tea.

In addition, scientists have also discovered through research that the main component of tea polyphenols, EGCG, is the "killer" of many cancers, especially for uterine cancer, skin cancer, lung cancer and other unique effects.

01The effective anti-cancer ingredients in tea polyphenols are disclosed

Director Jin Heiying is one of the researchers of Nanjing hereditary colon cancer.

He transplanted human colon cancer genes into mice. Soon, these mice became "dying" and became "patients" with colon cancer.

There is a main component of tea polyphenols in tea. It is said that the anti-cancer effect is mainly concentrated on this component. He injected this component into the mice every day. After two weeks, the growth rate of the tumor slowed down and it was obvious. The trend of shrinking.

Director Jin Heiying told reporters that everyone has always known that tea polyphenols have anti-cancer effects, but which ingredient in tea polyphenols is effective?

Later, experiments proved that EGCG, the main component of tea polyphenols, can restore the order of normal cells, destroy tumor cells, and accelerate tumor cell apoptosis.

Some domestic experts believe that treating animals with green or black tea can reduce esophageal cancer, gastric cancer or skin cancer in laboratory animals by 70%.

From this series of studies, it can be seen that the EGCG component does have an anti-cancer effect.

02Different teas have different anti-cancer effects

Director Jin Heiying told everyone that, in fact, different tea varieties have very different anti-cancer effects.

He said frankly that if the anti-cancer and anti-cancer effects of tea are ranked, then Oolong tea is ranked first, Pu'er tea second, black tea, such as Dancong black tea, and green tea fourth.

This is because fermented tea has more anti-cancer effects than unfermented tea.

In contrast, oolong tea and Pu-erh tea rank high, while green tea ranks low.

He analyzed that, first of all, EGCG in tea polyphenols has antioxidant activity. Second, EGCG inhibits the activity of enzymes that have a tumor-promoting effect.

These enzymes include protein kinase C, ornithine decarboxylase, cyclooxygenase and lipoxygenase. Third, tea polyphenols can promote the activity of enzymes with anti-cancer activity.

These enzymes include catalase, glutathione-S transferase and so on. Fourth, it can resist the activity of tumor proliferation. Fifth, people who drink tea regularly can enhance immunity.

It is reported that some scientists have used 1.25g green tea and 100mL boiling water tea soup as the only beverage for mice, which can reduce mouse lung tumors induced by chemical carcinogens by 36% to 44%, and reduce tumor reproduction by 44% to 60%.

Black tea also has the same effect. In addition, treating animals with green or black tea can reduce esophageal cancer, gastric cancer or skin cancer in experimental animals by 70%.

03The doctor recommends choosing tea according to personal taste

The reporter asked, according to the research results of medical experts and scientists, is it recommended that you only drink oolong tea?

In this regard, Director Jin Heiying said that although the results of the study are like this, everyone still has to choose tea according to their individual taste and taste.

04 Suggestion: Drink it within two hours after making tea

In fact, many people now like to make a large cup of tea before going out, then drink some, and then add water to it, usually from morning to night.

Is it healthy? Jin Heiying said that in general, after making tea, you need to drink the tea within two hours, and if you want to drink it, you need to re-infuse it.

There are many antioxidants in tea, and these antioxidants are composed of many unstable hydroxyl groups.

Generally speaking, these ingredients are not stable, so you should drink the tea within two hours of soaking. Otherwise, the active ingredients will change. Not only may they no longer have anti-cancer effects, but they may also have anti-cancer effects. Unfavorable substances for the body.

In Director Jin's opinion, the temperature of making tea and the choice of cups are also very important.

It is advisable to make tea at around 80 degrees as much as possible. Some people even use boiling water at 100 degrees to make tea, which may destroy the active ingredients in the tea.

In addition, the choice of cups, it is best to choose purple clay pots, and secondly choose porcelain, or glass cups, etc., it is best not to choose stainless steel insulated cups.

Is it better to use tea and medicine together?

According to research, if tea and anti-tumor drugs are taken together, the effect is better.

Seeing this, some people may be suspicious, "Didn't it mean that you can't take medicine with tea water?" I also consulted Director Jin on this topic. He said that the same service mentioned here does not mean taking medicine with tea water.

The meaning here is that if cancer patients have the habit of drinking tea while undergoing anti-tumor treatment, then the anti-cancer effect will be twice the result with half the effort.

In addition, experts also found that without any diet, exercise and other means, drinking 8-10 grams of tea a day, within 12 weeks, only the tea itself loses about 3 kilograms of fat.

Among all weight-loss products in Japan, Europe and the United States, tea products rank first.

05Small tea leaves, university asks

3. According to the test results of Japanese researchers, the anti-aging effect of tea polyphenols is 18 times stronger than that of vitamin E.

4. The medical research team of Showa University in Japan put 10,000 highly toxic Escherichia coli 0-157 in 1 ml of a tea polyphenol solution diluted to a concentration of 1/20 of ordinary tea. After five hours, all the bacteria died. Nothing left.

5. Drinking tea will make you happy inexplicably.

The amino acids in tea can promote the secretion of dopamine in large quantities, and dopamine is the substance that dominates human emotions, pleasure, libido, addiction and so on. The pleasure of drinking tea is involuntary and not controlled by mind.
