In recent years, the incidence of liver disease has been increasing, but the reasons behind it are shocking!Not because of smoking, drinking, but because of drinking tea. Since ancient times, we have been a big tea country, and the history of drinking tea has a long history, but if you don't drink tea correctly, it may damage the liver and even cause cancer.
1.Softens blood vessels
Tea can enhance the elasticity of blood vessels, promote blood circulation, dilate coronary arteries, and have a cardiotonic effect. It has a certain effect on the prevention of coronary heart disease, hypertension, stroke and other diseases, which is also the reason why most tea drinkers are elderly.
Drinking green tea can significantly reduce the total serum cholesterol content, especially the serum triglycerides, and green tea can alleviate and prevent cardiovascular disease and atherosclerosis.
2.Prevention and ** radiation injury
Tea polyphenols and their oxidation products have the ability to absorb radioactive substances. Clinical experiments have confirmed that for mild radiation sickness caused by tumor patients during radiation, tea extract can be used to achieve an effective rate of more than 90%.
For cytopenia, the effective rate of tea extract** is 81%.7%；It is also effective in leukopenia** caused by radiation.
3.Prevent tooth decay
Drinking tea, especially oolong tea, can prevent tooth decay because oolong tea has a high fluoride content, and fluoride ions have a great affinity for the calcium of teeth.
The synthesis of a kind of "fluoroapatite" that is relatively difficult to dissolve in acids is like adding a protective layer to the teeth, enhancing the ability of the teeth to prevent acid and caries. The rate of tooth decay among people who drink oolong tea is 60% lower than that of the general population.
4.Help**
Regular tea drinking by women can also help** because tea contains an ingredient called caffeine. After this ingredient is absorbed by the human body, it can promote the secretion of gastric juice, promote gastrointestinal digestion, and also strengthen the burning of fat to achieve the best effect. 
5.Refresh your mind
The caffeine in tea helps to increase alertness and focus, making a person feel refreshed and focused. And the amino acids found in tea, such as theanine and tea peptides, help to relax the body and mind and relieve stress.
Except for teas that can be stored for a long time like black tea and white tea, the shelf life of other teas is less than 5 years. Especially for green tea and yellow tea, the shelf life is only about 18 months. If you can't finish it that year, and if you leave it for a long time, it will expire, moldy, and deteriorate.
Many people are reluctant to throw away expired tea, and they may not be able to find out whether the tea is moldy and spoiled, and often continue to drink it. However, this approach is really wrong.
In addition to people in the tea industry, there are even many doctors who have called for stopping drinking this tea immediately, because it is more harmful to the liver than tobacco and alcohol, and it is not too late to know.
Moldy tea leaves produce aflatoxin, one of the strongest carcinogens recognized in the world. Long-term intake of aflatoxin can lead to the occurrence of liver cancer, stomach cancer, esophageal cancer and other cancers. In addition, aflatoxin can also damage the liver, leading to hepatitis, cirrhosis and other diseases. Therefore, if you find that the tea leaves are moldy, you must stop drinking them immediately.
Although alcohol and tobacco have been recognized as harmful to the liver, they may be less than one-tenth more harmful than moldy tea. Because both nicotine and alcohol in tobacco can cause damage to the liver, and aflatoxin directly disrupts the normal function of the liver, resulting in a greatly increased risk of liver cell cancer.
In the face of this serious health threat, each of us should be vigilant and learn to preserve tea properly. If you find signs of mold in the tea leaves, you should stop drinking them immediately and clean them up in time.
1.Humidity control
The ideal humidity for tea storage is usually between 60% and 70%. A humidity controller or silica gel desiccant can be used to keep the humidity at the right level. Placing some humidity regulators in the container where the tea leaves are stored can help control the humidity.
2.Separate storage
If you buy a lot of tea, you can store it in separate packages to avoid moisture and mold. Tea can also be placed next to desiccant or some items with moisture absorption ability to improve the dryness of tea leaves.
3.Avoid contact with odors
The adsorption performance of tea leaves on flavor is too strong, and she can absorb only a little bit. Therefore, the tea should be kept away from kitchen fumes, and if it is placed in the cabinet or refrigerator, it should also avoid smell. To do this, the key is sealing, as long as the sealing is thorough, we are not afraid of oil smoke.
4.Isolate the air
Tea can not be directly exposed to the air, on the one hand, the tea fragrance will be emitted, on the other hand, the contents of the tea will combine with the oxygen in the air to undergo a chemical reaction, so that the tea loses its original taste. If there are other odors in the air, the tea leaves will also adsorb, causing the tea to age.
1.Avoid drinking a lot of tea before and after meals
Tea should not be drunk about 20 minutes before and after meals, if tea is drunk, it will dilute gastric juice and affect food digestion. And because tea contains oxalic acid, oxalic acid reacts with iron and protein in food, affecting the body's absorption of iron and protein.
2.Do not drink tea on an empty stomach
Many people are accustomed to drinking tea on an empty stomach after getting up in the morning, which is a taboo for drinking tea, and it is also more harmful to the body. Tea contains more tea polyphenols and caffeine and other substances, if you drink tea on an empty stomach, these substances will combine with the protein in the stomach, which will irritate the stomach and easily hurt the stomach.
3.Do not take medicine with tea
Regarding "you can't take medicine with tea", it is believed that many people will be repeatedly instructed by doctors when they see a doctor.
Taking medicine with tea mainly affects the absorption of medicine, because many of the medicines we take are alkaline. The minerals and organic acids contained in tea are easy to neutralize with drugs containing alkaline substances, forming precipitated substances, which affects the efficacy of the medicine.
4.Avoid drinking too much tea
Although drinking tea can effectively maintain people's health to a certain extent, tea contains trace elements of fluorine. Therefore, excessive tea consumption will lead to excessive intake of fluoride, which may lead to poisoning in the long run.
In conclusion, tea, as an ancient and precious drink, deserves to be properly protected and stored. Moldy tea leaves not only lose their flavor, but can also pose a potential health threat. Therefore, understanding why tea leaves are prone to mold and how to avoid it is crucial for every tea lover.
