tea need to pay attention to these matters

should not drink tea at night

drinking tea at night will affect sleep, for food digestion and absorption is not good, and green tea is to avoid drinking. Because green tea belongs to non fermented tea, the content of tea polyphenols is higher and the irritation is stronger. Black tea is full fermented tea with weak irritation. Especially for people with weak spleen and stomach, adding milk when drinking black tea can play a certain role in warming the stomach. When drinking tea at night, put less tea and don’t make it too thick.

it is not suitable to drink tea after meals

drinking tea after meals will affect digestion and absorption just like drinking water. At the same time, tannic acid in tea can change the protein in food into a coagulant that is not easy to digest, increase the burden on the stomach and affect the absorption of protein. Tea contains a lot of tannic acid, which combines with the iron element in food to prevent the absorption of iron in the intestine. It is easy to cause iron deficiency in the human body, and even induce anemia. If you really like tea, you might as well drink it an hour after dinner.

don’t drink tea on an empty stomach

there are also some rules for drinking tea, especially the control of time should be reasonable. Drinking tea on an empty stomach can dilute gastric juice and reduce digestive function. In addition, the high absorption rate leads to a large number of harmful components in tea into the blood, causing dizziness, panic, weakness of hands and feet, headache, etc. & lt; Tea drinking & quot; Phenomenon.

should not drink strong tea

drinking tea can certainly refresh, but too strong tea does more harm than good to health. Many people mistakenly believe that drinking strong tea can remove high fat, clear heart and mind, and help digestion. In fact, on the contrary, the combination of tannin and protein in tea will produce astringent tannin protein, which will make people’s digestive system and excretion channels uncomfortable, slow down the peristalsis of large and small intestines, and prolong the retention time of feces in intestines. This is one of the factors causing constipation, and will also increase the risk of toxic substances and carcinogens being absorbed by the human body.

should not be greedy to drink new tea

there are many nutrients in tea, but many of them are also irritating to people’s intestines and stomach. From the perspective of nutrition, the freshest nutrients are not necessarily the best. Spring tea has just been processed, and polyphenols, alcohols and aldehydes have not been fully oxidized, which is a great stimulation to gastrointestinal tract. If you drink a lot of new tea, you may have diarrhea, abdominal distension and other adverse reactions. It is not suitable to drink tea after drinking

after drinking, the alcohol in the 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. After drinking tea, theophylline in tea can quickly play a diuretic effect on the kidney, so as to promote the undecomposed acetaldehyde to enter the kidney prematurely. Acetaldehyde has a greater stimulatory effect on the kidney, which will affect the renal function. Therefore, people who often drink strong tea after drinking are prone to kidney fibrosis. Not only that, the alcohol in wine has a great stimulatory effect on the cardiovascular system, but tea also has the effect of exciting the heart. The combination of the two enhances the stimulation on the heart. Therefore, drinking tea after heart disease is more harmful.

don’t drink a lot of tea when having a meal

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