Drinking tea to prevent cancer or cause cancer? The research data of 450,000 Chinese may turn out the opposite of what you think
In China, making a good pot of tea and tasting the fragrance is one of the great pleasures of many people's daily lives. Tea is more than just a drink, it's deeply rooted in Chinese culture and history.
For a long time, it was believed that drinking tea can maintain health and even help prevent diseases and prolong life. A recent large-scale study involving 450,000 Chinese could upend our traditional view of tea.
Tea, the historic "national drink", has been regarded as a symbol of health and longevity in China's cultural accumulation for thousands of years. Countless literati and writers praised it in their poems, and countless ordinary people enjoyed it in their daily lives.
However, with the deepening of scientific research, people have begun to pay attention to a question: can drinking tea regularly really prevent cancer, or does it actually increase the risk of cancer?
The study, which was conducted by multiple research institutions in China, covered 450,000 adults across the country and spanned more than a decade of follow-up.
The main objective of the study is to explore the relationship between tea drinking habits and several types of cancer.
The research team considered a wide range of variables, including participants' age, gender, lifestyle habits, dietary patterns, and genetic factors, to ensure the accuracy and applicability of the results.
The research methodology is rigorous, and the data is collected through questionnaires and regular health check-ups, and then combined with modern biostatistical techniques for in-depth analysis.
This large-scale population-based approach, while time-consuming and labor-intensive, provides very strong scientific evidence to help us understand the true relationship between daily habits and health.
The results of the study show that the relationship between tea and cancer risk is not static, but complex and conditional. Different types of tea have different effects on cancer risk.
For example, people who regularly consume green tea have a relatively low incidence of certain types of cancer, while the effects of black tea and oolong tea vary. This may be related to the type and content of bioactive substances in tea.
Research highlights the importance of drinking temperature. Long-term consumption of overheated tea may increase the risk of esophageal cancer.
There is a preliminary consensus in the medical community that overheated beverages may damage the esophageal mucosa and increase the possibility of cancer.
Lifestyle and genetic background are also important factors influencing the relationship between tea and cancer. For example, smoking and drinking habits may interact with tea's cancer-preventing effects, altering its impact on cancer risk.
Tea contains a variety of trace elements, some of which have been found to have anti-cancer potential. For example, selenium is an important antioxidant that helps repair DNA damage to the body's cells, potentially reducing the formation of cancer cells.
Research data suggests that selenium-rich tea is associated with a lower incidence of cancer.
Zinc is also a key immune system booster, which plays a vital role in maintaining cellular integrity and may help prevent the spread of cancer cells.
The content of these beneficial elements in tea is affected by soil conditions, cultivation methods, and tea processing.
This means that there may be significant differences in the cancer prevention potential of tea produced in different regions. When choosing tea, it becomes especially important to know where it comes from and how it is produced.
Potential risks of additives in tea
Many processed tea products on the market may add chemicals, such as artificial flavors and colours, to improve taste or appearance.
These additives may adversely affect the human body in some cases.
Studies have found that long-term intake of tea treated with certain additives may be associated with abnormalities in liver and kidney function and may even increase the risk of certain types of cancer.
Experts suggest that consumers should try to choose pure and natural products that have not been processed too much when buying tea, and pay attention to the ingredient description on the label, and avoid tea containing chemical additives as much as possible.
This study is not only a scientific examination of tea drinking habits, but also a reminder of public health awareness. While enjoying the various possible benefits of tea, we should also be alert to the potential risks.
Here are a few suggestions for tea lovers:
Choose high-quality teas, giving preference to products that are naturally grown and not overly processed.
Pay attention to the temperature of the tea and avoid drinking overheated tea for a long time to reduce the potential damage to the esophagus.
Drink tea in moderation, and while tea has many health benefits, drinking anything in excess can bring side effects.
Combined with the individual's health status and living habits, adjust the tea drinking behavior, and consult medical experts if necessary.
The relationship between tea drinking and cancer is indeed complex and changeable, and we need to make wise choices about our health while enjoying the comfort it brings.
I hope that every tea lover can find their own cup of healthy tea in the long-standing tea culture.
