The health benefits of drinking Pu 'er tea.
1, weight loss, lipid reduction, prevention and treatment of arteriosclerosis. 2, prevention and treatment of coronary heart disease, 3, blood pressure, 4, anti-aging, 5, help digestion, 6, anti-cancer, 7, hangover, 8, diuresis.
Many medical experiments have proved that continuous drinking of Pu 'er tea can reduce blood lipid by as much as 30% (depending on individual, of course). Pu 'er tea is closely related to fat metabolism. According to the research data, because it goes through a unique fermentation process, it can improve the function of enzymes to decompose waist and abdomen fat. Aspergillus in Pu 'er tea contains a small amount of lipase for lipolysis, which is effective for lipolysis. Fermented Pu 'er tea after Aspergillus can inhibit weight gain and reduce cholesterol and triglyceride in blood.
The benefits of drinking Pu 'er tea for smokers.
According to a survey report on smoking completed by the World Health Organization, the British Imperial Cancer Research Foundation and the American Cancer Society, at present, 10 people in the world die of diseases caused by smoking every 1 0 second, and at least 3150,000 people in the world die of smoking every year, and this number is still increasing; In China, the number of smokers has reached more than 300 million, and more than 100 million cigarettes are consumed every year, accounting for more than 30% of the total consumption in the world. In China, 70% of middle-aged men 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 will die from smoking every minute. This is undoubtedly a warning signal for smokers. From the health point of view, it is imperative to give up smoking. For those smokers who have difficulty in 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 all kinds of harmful substances contained in cigarettes, the toxins can be continuously released with tea drinking and excreted through feces while smoking. Smokers often drink tea, which has four main advantages:
Cigarette smoke contains more than 4,000 kinds of chemicals, of which more than 50 kinds are carcinogens, and the absorption through respiratory tract is the most conducive to the spread of carcinogens in these cigarettes throughout the body. Long-term smoking can not only lead to lung cancer, but also 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, and pointed out that the group variation caused by smoking is the direct cause of lung tumor. Drinking tea has anti-cancer and anticancer effects. 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 by human body during the process of respiratory metabolism while consuming oxygen. It exists in almost every cell of the human body, and it 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. In general, the human body is in a dynamic balance of continuous production and elimination of free radicals. It is worth pointing out that cigarettes are free radical generators. According to the measurement, people can generate 1017th power free radicals every day, and smoking will destroy this dynamic balance. Excessive production of free radicals increases the possibility of human carcinogenesis. Catechins, the main components of tea polyphenols, are antioxidants and strong inhibitors 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 they 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 nitrosamine synthesis in human body. Yan Yusen of Nanjing Zhongshan Cancer Institute found that tea polyphenols can combine with carcinogens after entering the human body, decompose them, reduce carcinogenic activity, and thus inhibit the growth of carcinogenic cells. Doroszi 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 president 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 at 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.
The harm of drinking Pu 'er tea to health;
Excessive drinking of strong tea can cause fluorosis.
People with constipation should not drink tea. Because the polyphenols in tea have a certain astringent effect on gastrointestinal mucosa, constipation patients will aggravate constipation if they drink tea.
People with neurasthenia or insomnia should not drink tea. Because caffeine in tea has obvious exciting effect on cerebral cortex, drinking tea will make the brain extremely excited and unable to rest.
People with iron deficiency anemia should not drink tea. Because tannic acid in tea leaves will make iron in food form a precipitate that is not absorbed by the human body, which will aggravate anemia.
People with calcium deficiency or fracture should not drink tea. Because the alkaloids in tea will inhibit the absorption of calcium by duodenum, it can also lead to calcium deficiency and osteoporosis, which makes it difficult for fractures to recover.
People with canker should not drink tea. Because theophylline in tea will reduce the activity of phosphodiesterase and make gastric parietal cells secrete a lot of gastric acid. Hyperacidity will inevitably affect the healing of ulcer surface, and also offset the efficacy of some antacids.
People with urinary calculi should not drink tea. Because tea contains more oxalic acid, drinking tea will aggravate the development of stones.
It is not advisable to drink tea when you have a fever. Because theophylline contained in tea can increase human body temperature, the cooling effect of drugs is greatly reduced or even disappeared.
Therefore, patients with fever should not drink tea.
