Pu'er tea, as one of the traditional Chinese teas, has a long history and is deeply loved by tea lovers. However, in recent years, the efficacy and safety of Pu'er tea, especially its relationship with cancer, have attracted widespread attention. In this context, the definition and regulation of Pu'er tea in the International Standard for Tea Classification is particularly important.
First of all, we need to make it clear that the International Standard for Tea Classification is mainly based on factors such as the processing technology and quality characteristics of tea, rather than directly judging its health effects. As a post-fermented tea, Pu'er tea occupies a unique position in tea classification due to its unique fermentation process and taste.
From the perspective of health preservation, Pu-erh tea is rich in tea polyphenols, catechins, caffeine and other health-promoting ingredients. When consumed in moderation, these substances can help lower lipids, blood pressure, antioxidants, etc., and have a positive effect on preventing cardiovascular diseases and improving digestion. Therefore, drinking Pu'er tea in moderation is undoubtedly in line with the concept of health preservation.
However, regarding the relationship between Pu-erh tea and cancer, scientific research has not yet given a clear conclusion. On the one hand, there are studies that show that certain components in tea have anti-cancer potential; On the other hand, there is also an opinion that excessive or improper consumption of Pu-erh tea may increase the risk of certain cancers. This is mainly related to the metabolism and transformation of caffeine, tea polyphenols and other substances in tea under specific conditions.
Therefore, we cannot simply classify Pu-erh tea as "health" or "cancer-nourishing". The health effects depend largely on factors such as how much is consumed, how it is consumed, and individual differences. While enjoying the mellow taste and unique cultural experience brought by Pu'er tea, we should also maintain a rational and scientific attitude and drink it in moderation according to our own conditions.
In summary, the classification of Pu'er tea in the International Standard for Tea Classification is more based on its process and quality characteristics, rather than directly evaluating its health effects. When drinking Pu-erh tea, we should pay attention to the principle of moderation and science to give full play to its health benefits while avoiding potential health risks.
