don’t drink a lot of tea

many people think that tea is a good health drink, so more is better, drink tea every day, just like drinking water.

in addition, tea contains theophylline, which has antioxidant effect. It is good for women to drink more tea, which has the effect of beauty. In fact, this idea is wrong.

tea does contain antioxidants, but it also contains fluorine. Excessive intake of body organs will be very stressful. In fact, too much theophylline is not suitable for women, women’s physique is relatively special, eating too much tea is prone to dysmenorrhea and endocrine disorders.

don’t drink tea before going to bed

some people have the habit of drinking tea before going to bed and can’t sleep without drinking. Some people can’t sleep or don’t want to sleep. In order to raise their spirits, they begin to drink tea in an attempt to restore their senses. However, the power of tea can last all night and play a role at 9 a.m., which completely disrupts the body’s biological clock. In the long run, there will be problems in the body.

the reasons why many people use tea instead of coffee are that coffee tastes too bitter, coffee is a chemical substance, and tea is healthy, so they prefer to drink more tea.

this idea really has a certain truth. In fact, whether it’s coffee or tea, these refreshing drinks will make the nerves of the brain excited for a short time. The brain can’t get enough rest for a long time, and it will become tired. Finally, it will become more and more listless.

it is recommended not to drink tea within 5 hours before going to bed to avoid falling asleep. In addition, people with weak spleen and stomach should drink less tea to avoid stimulating stomach to secrete gastric acid.

It is not harmful to drink a small amount of tea before or during a meal, but if you drink a large amount of tea or drink too much tea, it will affect the absorption of many major elements (such as calcium) and trace elements (such as iron and zinc). It should be noted that when drinking milk or other dairy products, do not drink tea at the same time. Theophylline and tannic acid in tea will combine with calcium in dairy products to form insoluble calcium salt, which will be discharged from the body, greatly reducing the nutritional value of dairy products.

it is not suitable to drink tea after drinking

after drinking, the alcohol in wine enters the blood through the gastrointestinal tract and is converted into acetaldehyde in the liver. Acetaldehyde is then converted into acetic acid, which is then decomposed into carbon dioxide and water for discharge. After drinking tea, theophylline in tea can quickly diuretic effect on the kidney, so as to promote the acetaldehyde not yet decomposed into the kidney prematurely. Acetaldehyde has a greater stimulating effect on the kidney, so it will affect the renal function. People who often drink strong tea after drinking are prone to kidney disease. Not only that, alcohol in wine has a great stimulation to cardiovascular system, but tea also has the effect of exciting heart. The combination of the two enhances the stimulation to heart, so drinking tea after drinking is more harmful to heart disease patients. The fresher the tea, the better. From the perspective of nutrition, the most fresh tea may not have the best nutritional components, because the so-called new tea refers to the tea that has been picked for less than a month. Because these teas have not been placed for a period of time, some substances that have adverse effects on the body, such as polyphenols, alcohols and aldehydes, have not been completely oxidized, There may be diarrhea, abdominal distension and other uncomfortable reactions. Too fresh tea is even worse for patients, such as those suffering from gastric acid deficiency or elderly patients with chronic gastric ulcer, who are not suitable for drinking new tea. New tea can stimulate their gastric mucosa, produce gastrointestinal discomfort, and even aggravate the disease.

Women drink tea

four should not

although tea has a very good health care effect, not every time can drink, especially female friends should pay special attention to, lest the body drink worse! The periods when female friends are not suitable to drink tea are:

1. During menstruation,

. During menstruation, menstrual blood will consume a lot of iron in the body, so female friends should supplement more iron rich vegetables and fruits, such as spinach, grapes and apples. Tea contains as much as 50% tannic acid, which will hinder the absorption of iron in our intestinal mucosa and greatly reduce the absorption of iron. Therefore, it is easy to combine with the iron in the chyme or the iron in the blood tonics in the intestines to produce precipitation.

2. During pregnancy, the caffeine concentration in general strong tea is as high as 10%, which will increase the number and frequency of urine and heartbeat of pregnant women, increase the load of heart and kidney of pregnant women, and more likely lead to pregnancy poisoning. Therefore, it is better for pregnant women not to drink tea.

3. During lactation, if you drink a lot of tea during this period, the high concentration of tannic acid in tea will be absorbed by mucous membrane, affecting the blood circulation of mammary gland, and then inhibiting the secretion of milk, resulting in insufficient milk secretion. In addition, the caffeine in tea will penetrate into the milk and indirectly affect the baby, which is harmful to the baby’s health.

4. In addition to dizziness and fatigue, there are also phenomena such as rapid heartbeat, bad temper and poor sleep quality. If you drink too much tea, it will aggravate these symptoms. Therefore, if people like to drink tea are in these special stages, it’s better to stop it, so as not to damage their body!

Nine misunderstandings

according to research, tea contains more than 600 kinds of chemical components, five of which are very beneficial nutrients to human body. However, in daily life, people’s understanding of tea also has many misunderstandings, which may bring hidden dangers to health. Misunderstanding 1: strong tea & quot; Sober up;. Some people think that drinking strong tea after drinking is a good way; Sober up & quot; This is a misunderstanding. Because after people drink alcohol, the alcohol in the wine enters the blood through the gastrointestinal tract, and is first converted into acetaldehyde in the liver, and then into acetic acid, and then decomposed into carbon dioxide and water, which is discharged from the body through the kidney. Drinking strong tea after drinking, caffeine in tea can quickly play a diuretic role, so as to promote acetaldehyde (which has a greater stimulatory effect on the kidney) not decomposed into acetic acid to enter the kidney prematurely, causing kidney damage. Misunderstanding 2: tasting new tea & quot; Be relaxed and happy;. New tea refers to less than a month of tea, this kind of tea shape, color, taste is superior, drink up is really a kind of enjoyment. But because the tea storage time is too short, polyphenols, alcohols, aldehydes content is more, if you drink new tea for a long time, you can have abdominal pain, abdominal distension and other phenomena. At the same time, new tea also contains tannic acid and caffeine with strong activity. Excessive consumption of new tea will make the nervous system highly excited, resulting in limb weakness, cold sweat and sleep; Tea drinking & quot; Phenomenon. Misunderstanding 3: drinking tea can raise blood pressure. Tea has the functions of anticoagulation, solubilization, inhibition of platelet aggregation, regulation of blood lipids, increase of high-density lipoprotein in blood and improvement of the ratio of cholesterol and phospholipids in blood. It can prevent cholesterol and other lipid masses from depositing on the wall of blood vessels, so as to prevent coronary artery narrowing. In particular, tea leaves contain catechins, which can reduce the cholesterol content in human body and blood lipids, So that the blood pressure drops. Therefore, drinking tea can prevent and treat cardiovascular disease.

error 4: & quot; Tea medicine has many diseases;. Some people think that tea is not only a safe drink, but also a good medicine for diseases. As everyone knows, for some patients, it is not suitable to drink tea, especially strong tea. Caffeine in strong tea can make people excited, insomnia, metabolic rate increased, not conducive to rest; Can also make hypertension, coronary heart disease, kidney disease and other patients heart rate, even arrhythmia, frequent urination, increase the burden of heart and kidney. In addition, caffeine can stimulate gastrointestinal secretion, which is not conducive to ulcer healing; The tannin in tea has astringent effect, which slows the intestinal peristalsis and aggravates constipation.

mistake 5: drinking tea on an empty stomach hurts the kidney. Some people are used to making tea 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 makes people panic. Tea contains a lot of caffeine, will accelerate the heart rate, lead to panic, in addition, will soon urinate, increase the burden of the kidney.

misunderstanding 6: drinking overnight tea hurts the kidney. After a night of tea, vitamins have been lost, and the protein and sugar in the tea soup will become the nourishment of bacteria and mold reproduction. Drinking overnight tea will easily cause stomachache and hurt the stomach and kidney.

mistake seven: drink tea for the first time. Because tea is polluted by pesticides and other harmful substances in the process of cultivation and processing, there are always some residues on the surface of tea. Therefore, the first time tea has washing effect, so it should be discarded.

mistake eight: drink tea after dinner. Tea contains a lot of tannic acid. Tannic acid can react with iron in food to produce new substances that are difficult to dissolve. Over a long period of time, it can cause iron deficiency in human body and even induce anemia. The right way is to drink tea an hour after the meal. Misunderstanding 9: drinking tea during menstruation. Drinking tea during menstruation, especially strong tea, can induce or aggravate menstrual syndrome. Medical experts found that compared with those who do not drink tea, those who have the habit of drinking tea 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 more likely to have menstrual tension.
