Is drinking more than 4 grams of tea daily or increasing the risk of cancer true or false? Peking University Research Results Announcement

Regarding this issue, Professor Li Liming's team from the School of Public Health at Peking University published a study in the European Journal of Epidemiology that found that drinking tea did not have much effect on preventing cancer.

Moreover, Professor Li Liming's team followed up 500000 subjects for a period of 10.1 years, and analyzed the relationship between the risk of multiple cancers and tea consumption based on the number of cancer cases recorded during this period through daily verification observations.

After relevant research, it has been found that drinking more than 4 grams of tea per day increases the risk of cancer by 13%. The risk of exposure to lung cancer also increases by 30%, and it also increases the risk of stomach cancer by 18%. Hearing this statement, I believe many people will also feel very scared. So does drinking tea really increase the risk of cancer?

However, it is worth noting that this study by Professor Li Liming's team is an Observational study, which may have population survey bias, as well as other factors, uncertain lifestyle, etc., so it cannot fully prove the causal relationship.

For example, for some tea enthusiasts, smoking, drinking, staying up late, and unhealthy eating habits in daily life can also increase the risk of cancer. So, excluding such multiple factors, the relationship between drinking tea and cancer is also significantly weakened.

There has always been a great controversy about drinking tea. Many people believe that drinking tea is beneficial for their health, and now there are rumors that drinking tea can cause cancer, which also makes people feel scared.

But in fact, this statement also has certain limitations, and there is no need to worry too much. Drinking tea appropriately is also beneficial for health preservation, supplementing the necessary nutrients, and is more conducive to personal health.

However, although drinking tea is beneficial for health preservation, it is also important to remember some taboos to prevent it from having a certain impact on the body.

Although drinking tea is good, these six taboos should be kept in mind

1. It is not advisable to drink tea on an empty stomach:Tannic acid in tea will stimulate Gastric mucosa, which is easy to cause stomach pain, nausea and other symptoms. Therefore, tea should not be drunk before meals or on an empty stomach.

2. Do not drink too much tea:Drinking too much tea may cause poisoning, and excessive tea polyphenols can create a burden on the human body. In addition, caffeine in tea can have an excitatory effect, which can easily lead to insomnia and headaches.

3. Drinking tea should not overheat:The structure of theophylline in tea is relatively stable, but it can change under high temperatures, forming harmful substances that are harmful to the body.

4. Pregnant women should not drink a large amount of tea:Tea contains substances similar to estrogen, and drinking a large amount of tea during pregnancy may affect the normal development of the fetus.

5. It is not advisable to drink tea during medication:The polyphenols in tea may have an impact on certain drugs and even reduce their efficacy, so it is not advisable to drink tea during medication.

6. Not suitable for drinking with other foods:Tea has a astringent effect, so it should not be consumed together with hot fruits, acidic beverages, alcohol, etc., as it may cause irritation to the intestines and stomach.

In short, drinking tea in moderation, paying attention to reasonable combinations, and avoiding the above six taboos can better enjoy the benefits brought by tea.
