"If you don't wash your cup when you drink tea, the king of Yan urges you to die." .

Scientific research shows that drinking water contains minerals and trace harmful heavy metal ions, such as cadmium, mercury and arsenic. When water is heated, the solubility of some calcium and magnesium ions decreases and the concentration of insoluble salts increases with the increase of water temperature. When water is concentrated to a certain extent, it will precipitate out. These precipitates can be brewed with water and enter the cup. If the tea leaves are not drunk for a long time or left exposed to the air, the tea polyphenols in the tea leaves and the metal elements in the tea rust will be oxidized, resulting in tea rust, commonly known as tea scale, which adheres to the inner wall of the cup. Tea rust contains cadmium, lead, mercury, arsenic and other harmful metals, which is the chief culprit endangering human health.

Li Zeng, an associate professor at Tianjin College of Medicine, said in an interview: "Tea scale contains toxic substances such as cadmium, lead, mercury and arsenic and carcinogens such as nitrite, which will adhere to the smooth surface of the teacup. As tea enters the body and human digestive system, it combines with protein, fatty acids and vitamins in food to form insoluble precipitate, which not only hinders the absorption and digestion of these nutrients, but also damages the stomach and other organs. In addition, teacups that are often not cleaned have a lot of scale, which also contains a lot of heavy metals, which is extremely unfavorable to health. " At the same time, these oxides can also cause diseases and dysfunction of nervous system, digestive system, urinary system and hematopoietic system, and even cause premature aging, especially arsenic and cadmium can cause cancer, cause fetal malformation and endanger health.

How to wash away tea dirt completely

The thicker the tea scale, the harder it is to clean, so daily cleaning is as important as regular cleaning. Experts suggest that after drinking tea every time, even if there is no obvious tea stain on it, the tea set should be carefully cleaned to avoid many a mickle makes a mickle.

(1) Tea scale has been deposited for a long time, and it is difficult to clean it. Soak in heated rice vinegar or baking soda for a day and a night, and then brush with a toothbrush, which is easy to clean. It should be noted that if you use a teapot, you don't need to clean it like this. The teapot itself has pores, and the minerals in the tea scale can be absorbed by these pores, which can not only maintain the teapot, but also prevent harmful substances from "running" into the tea and being absorbed by the human body.

(2) Put a teaspoon of orange powder or orange juice in the teacup and teapot, fill it with clear water and let it stand for 2-3 hours, so that the tea scale loses its adhesion with the tea set and can be easily removed.

(3) Add water to the teapot or teacup, add potato skins, heat and boil, and rinse after cooling, so it is easy to clean.

(4) When the metal tea partition is used, it will turn black due to tea dirt. If it can't be washed off with a medium-sized cleaner, it can be soaked in vinegar or easily cleaned with bleach.

(5) Coat it with edible salt, especially where there is tea dirt. Then scrub the teacup with a toothbrush, and finally rinse it with clean water.

Experts especially remind that it is best not to use rough cleaning tools such as steel balls and cleaning balls to clean tea stains, because these cleaning tools are easy to damage the enamel on the inner wall of the tea set, making it thinner and thinner, and the tea stains generated in the future are easy to penetrate into the deep layer of the tea set, which is extremely difficult to completely remove. Individuals should use a soft brush or toothbrush and a mild cleaning cloth to clean.

Black tea is mild in nature and mellow in aroma, which helps to strengthen bones first. Researchers from Cambridge University School of Medicine investigated the diet and bone mineral density of 256 women aged 65-76 who lived nearby. The results show that tea is rich in flavonoids, which can reduce the risk of osteoporosis in women. Secondly, drinking black tea can prevent and treat influenza, myocardial infarction, stroke and skin diseases. Studies have found that frequent mouthwashing with black tea or direct drinking can prevent influenza; Black tea is rich in trace element potassium. After brewing, 70% potassium can be dissolved in tea, which can enhance blood circulation of the heart and reduce calcium consumption in the body. People who drink five cups of black tea a day have a lower risk of stroke than those who don't drink black tea. It is best to drink black tea with milk. People who drink tea without milk have a relatively high proportion of oxalic acid in their bodies. Generally, oxalic acid can be excreted with urine, but for some people, some oxalic acid will still accumulate in the body and eventually form kidney calculi. Calcium in milk can be combined with oxalic acid, which can be eliminated smoothly. It is recommended to drink black tea at night. Because green tea belongs to non-fermented tea, the content of tea polyphenols is high, which keeps its original properties and is relatively strong; Black tea is a completely fermented tea.

Especially for people with weak spleen and stomach, adding some milk when drinking black tea can play a certain role in warming the stomach.
