The human body is a natural tobacco regulator. Reasonable diet adjustment, eating less foods containing high fat, eating more fresh vegetables and fruits, eating more iron-rich soybeans, egg yolks, milk rich in vitamin b 12 and apples rich in vitamin C can supplement the loss and reduction of vitamin C and antioxidants caused by smoking, eliminate excess oxygen free radicals in the body, and help to coordinate the balance between free radical generation and elimination, oxidation and reduction in the body, thus maintaining good health.

Nicotine enters the human body with smoke, which will make cholesterol adhere to the blood vessel wall, leading to arteriosclerosis; A large amount of taurine in oysters can decompose cholesterol, so eating more oysters can solve nicotine poisoning; Others found the bane of nicotine in milk, broad beans and fruits. These foods contain vitamin b2, which can decompose 3,4-benzo [a] pyrene compounds in tar, and the decomposed compounds will be excreted with cellulose, so eat more vegetables.

According to scientific research, drinking tea can reduce the harm of smoking, because tea polyphenols, vitamin C and other components in tea can degrade various harmful substances contained in cigarettes. When smoking while drinking tea, toxins can be released continuously with drinking tea and excreted through feces.

According to research, tea does have the ability to block the synthesis of nitrosamines in human body; Tea polyphenols can combine with carcinogens after entering the human body, decompose carcinogens, reduce carcinogenic activity, and thus inhibit the growth of carcinogenic cells; The leaves of green tea are rich in anticancer substances, and their concentration is quite high enough to produce anticancer effect in human body. Dr. John weisberg, honorary chairman of the American Health Foundation, said: "My research shows that if you drink six cups of tea every day, you can avoid cancer." Therefore, smokers drinking tea can help reduce the occurrence of cancer.
