Smokers who regularly drink tea mainly enjoy four major benefits:
First, it can reduce the likelihood of smoking-induced cancer. Cigarette smoke contains over 4,000 chemical substances, more than 50 of which are carcinogenic. Absorption through the respiratory tract most facilitates the spread of these carcinogens throughout the body. Long-term smoking can not only lead to lung cancer but also various cancers such as esophageal cancer, laryngeal cancer, pancreatic cancer, kidney cancer, and bladder cancer. Smokers account for 80% to 99.5% of lung cancer patients. Researchers from the Anderson Cancer Center in Houston, USA, elucidated the relationship between smoking and lung cancer from a molecular perspective, indicating that gene mutations caused by smoking are the direct cause of tumors. Drinking tea has anti-cancer effects. Tea polyphenols in tea can inhibit the release of free radicals and control the proliferation of cancer cells. Free radicals are harmful "waste" produced during the human body's respiratory metabolism while consuming oxygen. They exist in almost every cell of the human body, representing a major hidden danger and "time bomb." Research shows that free radicals are also an important cause of gene mutations and cancer. Under normal circumstances, the human body maintains a dynamic balance between constant free radical production and elimination. It is worth noting that cigarettes are free radical generators. According to measurements, smoking one cigarette can produce 10^17 free radicals, disrupting the original dynamic balance. Excessive free radical production increases the likelihood of human carcinogenesis. Catechin compounds, the main components of tea polyphenols, are antioxidants and potent free radical inhibitors. They can inhibit tumor development caused by smoking. Green tea polyphenols have a strong ability to清除 free radicals and are highly effective in清除 superoxide anion free radicals. The Institute of Nutrition and Food Hygiene of the Chinese Academy of Preventive Medicine, after studying 145 types of tea, confirmed that tea can indeed block the synthesis of nitrosamines in the human body. Yan Yusen from the Nanjing Zhongshan Cancer Research Institute found through experiments that tea polyphenols can bind with carcinogens after entering the human body, decomposing them and reducing their carcinogenic activity, thereby inhibiting the growth of cancer cells. Dorothy Moore from Purdue University, engaged in food and nutrition research, said: "Our research shows that green tea leaves are rich in anti-cancer substances at concentrations high enough to produce anti-cancer effects in the body." Dr. John Weisburger, honorary president of the American Health Foundation with forty years of experience in cancer research, stated: "My research results indicate that if you drink six cups of tea a day, you may avoid cancer." Research results from the Harlem Medical Center at Columbia University also show that green tea has anti-cancer effects. Therefore, drinking tea helps smokers reduce the incidence of cancer.
