Second, the better life, the more important it is to fight fat. The "oil scraping" effect of Pu 'er tea is well known. Even Mr. Lu Xun's stomach was upset after eating a big meal when he was a child, and he would break a small piece of Pu 'er tea and drink it. At present, Pu 'er tea can alleviate obesity, "three highs" and other problems that plague urbanites, such as detoxification, nourishing stomach, diminishing inflammation, lowering cholesterol, reducing fat, beautifying, losing weight, etc ... The health care function of Pu 'er tea can almost be said to be "a unique tea forest". Problems that may occur when drinking ordinary tea, such as stomach injury, insomnia, polyuria and so on. Pu 'er tea will not appear, but it has the effect of nourishing the stomach and promoting sleep, which is amazing.
Disadvantages: the first point: drinking new tea often can easily induce stomach problems. Because of its short storage time, new tea contains more unoxidized polyphenols, aldehydes, alcohols and other substances, which has a strong stimulating effect on human gastrointestinal mucosa. Therefore, drink less new tea, and avoid new tea stored for less than half a month, otherwise there will be many disadvantages.
The second point: drinking tea on an empty stomach will dilute gastric juice, reduce digestive function, increase water absorption rate, and lead to a large number of bad ingredients in tea entering the blood, causing dizziness, palpitation, weakness of hands and feet and other symptoms.
The third point: drinking tea with a fever is tantamount to "adding fuel to the fire", because tea contains theophylline, which has the effect of raising body temperature and will greatly reduce or even disappear the cooling effect of drugs.
Fourth: If you often have gastrointestinal ulcers, you should actually drink less tea, because caffeine in tea will promote the secretion of gastric acid, increase the concentration of gastric acid, induce ulcers and even perforation.
Fifth: If you are often constipated, don't drink tea. Because polyphenols in tea have a certain astringent effect on gastrointestinal mucosa, constipation patients will aggravate constipation if they drink tea.
Sixth point: If you often suffer from insomnia recently, don't drink tea. Because the caffeine in tea has obvious exciting effect on the cerebral cortex, it will make the brain in an extremely excited state without rest.
Point 7: If you are iron-deficiency anemia, please drink less 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.
Eighth point: The majority of female friends should pay attention to this point, because the alkaloids in tea will inhibit the absorption of calcium by duodenum, and at the same time, it will also lead to calcium deficiency and osteoporosis, making it difficult to recover the fracture. Especially after the age of 30, women lose calcium faster. If they like drinking tea, they should take more calcium supplements.
Ninth: Pregnant women are not suitable for drinking tea during pregnancy. Generally, the concentration of caffeine in strong tea is as high as 10%, which will increase the urine volume of pregnant women, increase the number of heartbeats and increase the load on the heart and kidneys.
Point 10: Women should not drink tea during menstruation, especially strong tea, which will induce or aggravate menstrual syndrome. Medical experts have found that compared with people who don't drink tea, people who have tea habits are 2.4 times more likely to have menstrual tension, and those who drink more than 4 cups of tea a day are 3 times higher.
