Green Tea: Helping to Healing Cancer Fighter

Green Tea: Helping to Healing Cancer Fighter

Tea is an important natural healthy drink consumed worldwide, proven by numerous scientific studies around the world. Thanks to the presence of a wide range of bioactive molecules in a "cup" of tea, it makes tea an attractive and compelling example of a functional food. Encouraging scientific results on tea consumption in human health makes tea popular in human society. Although tea is not yet recognized as a medicinal agent, it is one of the most sought after herbal remedies

Green tea polyphenols that act as antioxidants can inhibit the growth of existing cancer cells. The active agent believed to have this effect is an antioxidant, epigallocatechin-3-gallate (EGCG). Recent clinical studies have also indicated that regular use of green tea can reduce the risk of certain cancers, including oral, skin, prostate, colon, stomach, and rectal cancers. In a clinical study, patients with pre-cancerous oral lesions, who were treated with green and black tea extracts

Cancer and tea

Green tea polyphenols have been widely studied as cancer chemotherapy preventive agents. Catechins are main polyphenols consisting of (-) - epigallocatechin-3-gallate (EGCG), (-) - epigallocatechin (EGC), (-) - epicatechin-3-gallate (ECG) and (-) - epicatechin (EC) of these EGCG is the most abundant and active compound that can block the progression of cancer. According to a case study, there is an association between green tea and colorectal cancer risk

A meta-analysis of 13 case-control studies, the results indicate a weaker lower trend for colorectal cancer development with the consumption of green tea, but the available epidemiological data are insufficient to conclude that green tea can protect against colorectal cancer. man. In general, the anticancer activities of tea polyphenols are believed to be related to their antioxidant properties. Tea can also influence the metabolism of carcinogens by induction or inhibition of various cytochromes P450

Effect of tea consumption in the fight against different types of cancer:

• Lung cancer: a researchers found that Okinawan tea, which is similar to green tea, but partially fermented was related to a reduced risk of lung cancer, particularly among women

• Pancreatic cancer: major tea drinkers were less likely to develop pancreatic cancer than non-drinkers. However, further studies are needed to strongly recommend it

• Prostate cancer: laboratory researchers have found that green tea extracts prevent the growth of prostate cancer cells in test tubes. However, neither black nor green tea should be taken during chemotherapy treatment, as both were less sensitive during that period

• Esophageal cancer: a large population-based study found that green tea offers significant protection against the development of esophageal cancer (particularly among women). Another population-based study revealed exactly the opposite. In point of fact, the stronger and hotter the tea, the greater the risk. Therefore, more research is needed before recommending green tea for the prevention of esophageal cancer

• Stomach cancer: in two studies that compared green tea consumers with non-consumers, researchers found that people who drank tea were about half as likely to grow stomach cancer and gastritis (inflammation stomach) compared to those who drank tea. However, a recent study found no association between green tea consumption and stomach cancer risk. Further research in this line can only confirm whether green reduces the likelihood of developing this disease
