Nine misunderstandings:

According to research, tea contains more than 600 chemical components, five of which are very beneficial nutrients to human body. However, in daily life, people have many misunderstandings about tea, which may bring hidden dangers to health.

Myth 1: Strong tea "sobers up". Some people think that drinking strong tea can "sober up", which is a misunderstanding. Because people drink alcohol, the alcohol in the wine enters the blood through the gastrointestinal tract, first converted into acetaldehyde in the liver, then converted into acetic acid, then decomposed into carbon dioxide and water, and excreted through the kidney. However, after drinking strong tea, caffeine in tea can quickly play a diuretic role, thus promoting acetaldehyde (a substance that has a great stimulating effect on the kidney) to enter the kidney prematurely and damage the kidney.

Myth 2: tasting new tea is "refreshing". New tea refers to tea that has been picked for less than a month. This kind of tea has good shape, color and taste, and it is really a pleasure to drink. However, due to the short storage time of tea, there are many polyphenols, alcohols and aldehydes. If you drink new tea for a long time, you may have abdominal pain and bloating. At the same time, new tea also contains highly active tannic acid and caffeine. Excessive drinking of new tea will make the nervous system highly excited, and it is prone to "tea drunkenness" such as limb weakness, cold sweat and drowsiness.

Myth 3: Drinking tea will raise blood pressure. Tea has the functions of anticoagulation, promoting dissolution, inhibiting platelet aggregation, regulating blood lipid, raising high-density lipoprotein in blood and improving the ratio of cholesterol to phospholipid in blood, and can prevent lipid lumps such as cholesterol from depositing on the blood vessel wall, thus preventing coronary artery from narrowing. In particular, tea contains catechins, which can reduce the cholesterol content and blood lipid in the human body, thus lowering blood pressure. Therefore, drinking tea can prevent and treat cardiovascular diseases.

Myth 4: "Tea bags cure all diseases". Some people think that tea is not only a safe drink, but also a good medicine for treating diseases. As we all know, for some patients, it is not advisable to drink tea, especially strong tea. Caffeine in strong tea can make people excited, insomnia and increase metabolic rate, which is not conducive to rest; It can also accelerate the heartbeat of patients with hypertension, coronary heart disease and nephropathy. Even arrhythmia and frequent urination will increase the burden on the heart and kidneys. In addition, caffeine can also stimulate gastrointestinal secretion, which is not conducive to the healing of ulcer disease; Tannin in tea has astringent effect, which can slow down intestinal peristalsis and aggravate constipation.

Myth 5: Drinking tea on an empty stomach hurts the kidney. Some people are used to making tea when getting up in the morning. In fact, drinking tea on an empty stomach is a very unhealthy habit. As the saying goes, drinking tea on an empty stomach is scary. Tea contains a lot of caffeine, which will accelerate the heart rate and lead to palpitation. In addition, it will urinate quickly and increase the burden on the kidneys.

Myth 6: Drinking overnight tea hurts the kidney. After a night of tea, vitamins have been lost, and protein and sugar in tea soup will become nutrients for bacteria and molds to reproduce. Drinking tea overnight is easy to hurt your stomach and kidney.

Myth 7: Drink tea all over your head. Because tea is polluted by harmful substances such as pesticides in the process of planting and processing, there will always be some residues on the surface of tea, so the first-time tea should be discarded because of its washing function.

Myth 8: Drink tea after meals. Tea contains a lot of tannic acid, which can react with iron in food to form new substances that are difficult to dissolve. Over time, it will cause iron deficiency and even induce anemia. The correct way is to drink tea an hour after meals.

Myth 9: Drinking tea during menstruation. Drinking tea during menstruation, especially strong tea, 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.

The World Health Organization investigated the advantages and disadvantages of drinks in many countries, and finally concluded that tea is the best drink for middle-aged and elderly people. According to scientific determination, tea contains 10 kinds of vitamins, including nearly 300 kinds of ingredients such as protein, fat, tea polyphenols, caffeine and lipopolysaccharide, which can regulate physiological functions and play a variety of health care and pharmacological effects.

Because tea can prevent the increase of sterols in human body and prevent myocardial infarction, tea polyphenols can also remove excessive free radicals, inhibit and kill pathogenic bacteria. In addition, tea has the functions of refreshing, eliminating fatigue and resisting bacteria. This is necessary for middle-aged people. Euromonitor can also purify water and reduce the harm of radioactive substances to human body. Therefore, people living in cities should drink tea regularly, especially when the natural environment is seriously polluted.
