Drinking tea can reduce the harm of smoking.
According to a survey report on smoking jointly completed by the World Health Organization, the British Imperial Cancer Research Foundation and the American Cancer Society, at present, 10 people die of diseases caused by smoking every 1 0 second in the world, and at least 3150,000 people die of smoking every year in the world, and this number is still increasing; In China, the number of smokers has reached more than 300 million, and/kloc-0.50 billion cigarettes are consumed every year, accounting for more than 30% of the world's total consumption. 70% of middle-aged men in China smoke, and 1 person dies of smoking every minute. If the number of smokers in China is still increasing, it is estimated that five people die from smoking every minute. This is undoubtedly a warning signal for smokers. From a health point of view, it is imperative to give up smoking. For those smokers who have difficulty quitting smoking for a while, drinking tea is the best way to reduce the harm of smoking. Because tea polyphenols, vitamin C and other components in tea can degrade various harmful substances contained in cigarettes, toxins can be released continuously with drinking tea and excreted through feces when smoking. Smokers often drink tea, which has four advantages:
First, it can reduce the possibility of cancer caused by smoking. Cigarette smoke contains more than 4000 kinds of chemicals, of which more than 50 kinds are carcinogens. It is most beneficial for the carcinogens in these cigarettes to spread to the whole body through respiratory absorption. Long-term smoking will not only lead to lung cancer, but also lead to esophageal cancer, laryngeal cancer, pancreatic cancer and renal cancer. Bladder cancer and other cancers, especially lung cancer patients, account for 80% to 99.5%. Researchers at the Anderson Cancer Center in Houston, USA, clarified the relationship between smoking and lung cancer from the molecular point of view, pointing out that the population variation caused by smoking is the direct cause of lung tumors. Drinking tea has the function of preventing cancer. Tea polyphenols in tea can inhibit the release of free radicals and control the proliferation of cancer cells. Free radicals are a group of harmful "garbage" produced in the process of respiratory metabolism while consuming oxygen. It exists in almost every cell of the human body, which is a hidden danger and a "time bomb" for the human body. Studies have shown that free radicals are also an important cause of genetic variation and carcinogenesis. Generally speaking, the human body is in a dynamic balance of constantly producing and scavenging free radicals. It is worth pointing out that cigarettes are free radical generators. According to the measurement, people can produce 1017th power free radicals every day, and smoking will destroy this dynamic balance. Excessive production of free radicals increases the possibility of human carcinogenesis. Catechin, the main component of tea polyphenols, is an antioxidant and a strong inhibitor of free radicals, which can inhibit the occurrence of tumors caused by smoking. Tea polyphenols in green tea have a strong ability to scavenge free radicals, and have a strong scavenging effect on superoxide anion free radicals. After studying 145 kinds of tea, the Institute of Nutrition and Food Hygiene of Chinese Academy of Preventive Medicine confirmed that tea has the ability to block the synthesis of nitrosamines in human body. Yan Yusen of Nanjing Zhongshan Cancer Institute found that tea polyphenols can combine with carcinogens after entering the human body, decompose carcinogens, reduce carcinogenic activity, and thus inhibit the growth of carcinogenic cells. Dorothy Moore, who is engaged in food and nutrition research at Purdue University in the United States, said: "Our research shows that the leaves of green tea are rich in anticancer substances, and their concentration is quite high enough to produce anticancer effects in the body." Dr. John weisberg, honorary chairman of the American Health Foundation, who has rich experience in cancer research for 40 years, said: "My research results show that if you drink 6 cups of tea every day, you can avoid cancer." The research results of researchers in Harlem Medical Center of Columbia University also show that green tea has anti-cancer effect. Therefore, smokers drinking tea can help reduce the occurrence of cancer.
Secondly, it can help reduce the radiation pollution caused by smoking. According to the research of Dr. Joseph Duffrin Zan of the University of Massachusetts Medical Center, a person who smokes 30 cigarettes a day will be exposed to radioactive substances in cigarettes within one year, which is equivalent to his skin being seen about 300 times through a chest X-ray machine. However, drinking tea can effectively prevent radioactive substances from invading bone marrow and make strontium 90 and drill 60 excreted quickly. Catechin and lipopolysaccharide in tea can reduce the harm of radiation to human body and have significant protective effect on hematopoietic function. Clinical trials of camellia oleifera abel. in the treatment of radiation-induced mild radiation sickness show that the total effective rate can reach 90%.
Third, it can prevent and treat cataracts caused by smoking. Scientific research has found that smoking is becoming the enemy of eye health and will promote cataracts. Researchers at Harbin University School of Medicine in the United States found that people who smoke more than 20 cigarettes a day are twice as likely to develop cataracts as non-smokers. The more they smoke, the more likely they are to have cataracts. In China, 4% of the unexplained blind people are caused by smoking. Canadian scientists have found that drinking more tea can prevent cataracts. They believe that cataracts are caused by free radicals produced by oxidation reactions in human body acting on the lens of eyeball, and the metabolites with antioxidant effect produced by decomposition of tea polyphenols in tea can prevent the occurrence of oxidation reactions that produce free radicals in human body. In addition, scientists from the Nutrition and Aging Research Center of the US Department of Agriculture recently found that the incidence of cataract is closely related to the content and concentration of carotene in human plasma. The concentration of carotene in plasma of cataract patients is often very low, and the incidence rate is 3 ~ 4 times higher than that of normal people. The content of carotene in tea is much higher than that of ordinary vegetables and fruits. Carotene not only has the functions of preventing cataracts and protecting eyes, but also has the functions of preventing cancer, resisting nicotine and relieving tobacco poison. Smoking tea is good for protecting their eyesight.
Fourth, vitamin C consumed by smoking can be supplemented. Because smoking can promote the combination of vitamin C in human serum with oxidative carcinogens such as carbon monoxide, nitrosamines, nicotine, formaldehyde, etc. in smoke, and then it can be transformed into non-toxic compounds or non-mutant substances to be excreted, so that the content of vitamin C is greatly reduced, leading to a large accumulation of garbage free radicals in human body, leaving hidden dangers to human body and aggravating the damage of free radicals to various normal cells. Binu inhaled nicotine and other harmful substances, which increased the concentration of oxygen free radicals in cells. Oxygen free radicals are harmful to human cells and are easy to cause canceration. Researchers in the United States have found that regular supplementation of a certain dose of vitamin C can avoid this harm caused by smoking. Because vitamin C has an antioxidant effect, it can inhibit the production of oxygen free radicals and protect human cells from infringement. Tea is rich in vitamin C, especially green tea. Under normal circumstances, the leaching rate of vitamin C in tea can reach about 80%, and vitamin C in tea soup is rarely destroyed at 90 degrees Celsius. Smoking and drinking tea can get a proper amount of vitamin C, especially insisting on drinking green tea can completely supplement the deficiency of vitamin C caused by smoking, thus maintaining the dynamic balance of free radical generation and elimination in the human body and enhancing human resistance.
In short, although drinking tea has certain benefits for smokers, it does not encourage you to continue smoking, nor does it mean that you can smoke without restraint because drinking tea can reduce the harm of smoking. On the contrary, because the harm that smoking brings to individuals and society is enormous and painful, it is a general trend and a wise move to quit smoking. Drinking tea can only be used as a remedial measure in the process of quitting smoking to minimize the harm of smoking. For your health, giving up smoking completely is our ultimate goal.
