Drinking tea also needs to be careful when it exceeds 70 °C.


Drinking tea also needs to be careful when it exceeds 70 掳C.

Drinking tea also needs to be careful over 70 掳C will cause cancer. Iranian researchers published a study in 2009 that drinking a cup of hot tea every day is likely to increase the risk of esophageal cancer.

Moreover, when the tea water temperature is between 65 掳 C?
At 69 掳 C, the risk of esophageal cancer will double, once the water temperature of tea exceeds 70 掳 C, the incidence of esophageal cancer will increase by 8 times.

If the tea is finished within 2 minutes after the tea is poured out, the risk of suffering from esophageal cancer will increase by about 5 times after 4 minutes.

Another study found that when drinking tea, the tea temperature is between 56 掳 C?
60 掳 C, is beneficial to many health.

In addition to the high temperature of tea may increase the risk of cancer, dietitians reminded that if tea leaves pesticides when drinking tea, it may also be detrimental to health.

If you are concerned about pesticide residue, you can pour off the water in the first bubble, and open it when you make tea. Do not smother the water vapor, so some pesticide substances will evaporate with water vapor.

When purchasing tea, try to choose organic tea, which is extra safe.

So, what is the principle of drinking tea to prevent cancer? Can some cancers in daily life be prevented by drinking tea?

First, how to drink tea to prevent cancer 1. The anti-cancer effect of green tea At home and abroad, some studies have proved that both tea and chemical carcinogenic or metastatic tumors of experimental animals have different effects.

Any endogenous or exogenous free radicals have carcinogenic effects, but natural antioxidants can scavenge free radicals. Therefore, the anti-cancer and anti-cancer effects of this natural antioxidant are perceived by some people.

Natural antioxidants such as green tea poisonous “tea polyphenols” are exchanged before or after meals. A variety of antioxidants synergistically act to scavenge free radicals, and more can show the anti-cancer and anti-cancer effects of green tea.

2, green tea polyphenols are important green tea anti-cancer substances in green tea green tea polyphenol content is five times that of ordinary tea, green tea can reduce the occurrence of certain cancers, but scientists in the past are not clear, what is the substance in prevention,Therefore, it is impossible to decide how much green tea a person should drink in a day.

Green tea polyphenols may be just one of the substances that have anticancer effects in green tea.

They also found that the molecular structure of green tea polyphenols is similar to that of the anticancer drug methotrexate tablets (methotrexate).

DHFR is essential for healthy cells and cancer cells. Green tea polyphenols have strong binding to DHFR, but are weaker than methotrexate tablets, so diabetes is less than anticancer drugs for healthy cells.

3, the anti-cancer effect of Pu’er tea After comparing the effects of different green teas, it is considered that the skin of Pu’er tea is more serious. The cancer patients have long been called Pu’er tea, which can expand the contraction and round the circle.The amount is reduced, the attachment and wandering ability is lost, and even the floating loss is lost; the residual is also reduced to round and concentrated, the nucleus is condensed, the chromatin is condensed or disappeared, the vacuoles appear in the nucleus and the granule, and the nucleolus is condensed or broken.The cleavage disappears, the chromosomal contraction shrinks or coagulates, the ribosome decreases, the mitochondria and endoplasmic mitochondria expand; RNA synthesis decreases, and nuclear division stops.

These changes prove that under the pharmacological action of Pu’er tea, the polymer tends to die from degeneration.

Second, drinking tea can prevent cancer. 1. Drinking tea can prevent prostate cancer. According to recent research, whether drinking black tea or drinking green tea can prevent prostate cancer, and it can also reduce obesity and reduce cell damage caused by smoking.It can even prevent heart disease.

Foreign researchers surveyed 20 male patients with prostate cancer. They drank 5 cups of green tea, black tea, etc. before surgery. After blood analysis and prostate tissue analysis, they found that the phenolic content was higher in their tissue samples.Adding black tea, green tea or soda to the phosphate culture solution revealed that the phosphate growth rate was significantly slowed down.

2, drinking green tea is good for preventing ovarian cancer Researchers in Mexico and China recently found that green tea can reduce the incidence of ovarian cancer in women. The incidence of ovarian cancer in women who insist on taking green tea every day can be reduced by nearly 60% compared with other women.

Researchers at Curtin University and Zhejiang Cancer Hospital in China conducted experiments on 900 women in order to understand the cause of ovarian cancer.

Of these, 254 have been diagnosed with ovarian cancer and 652 are healthy women.

It was found that drinking tea daily, especially green tea, can greatly reduce the incidence of ovarian cancer in women.

In addition to drinking tea, other factors such as smoking, oral contraceptives, physical exercise, and a family history of ovarian cancer can have different effects on ovarian cancer.

3, drinking green tea can prevent skin cancer Researchers at the American College of Medicine recently found that drinking a few cups of tea a day can reduce the risk of two common skin cancers.

After studying the eating habits and health status of 2,200 adults, the research team found that people who drank tea had less risk of developing common skin cancers, squamous cell carcinoma and basal cell carcinoma.

People who drink more than one cup a day may be 20% to 30% lower than those who do not drink tea.

Studies have shown that there is an antioxidant called EGCG in tea that limits the damage of UV radiation to the skin.

This effect is even more pronounced in people who have been drinking tea for decades and who drink at least two cups of tea a day.

Experts in the research team pointed out that the above findings do not mean that no sunscreen is needed as long as you drink tea.

There is no evidence that drinking tea can reduce the risk of skin cancer in people who have sunburned many times.
