It is well known that drinking tea is good for health. Drinking tea regularly can have the effect of health care. Friends who often drink tea will find that there is a layer of tea stain on the tea set. It is very troublesome to wash the tea scale. Therefore, many people do not pay attention to cleaning and carelessness. As everyone knows, this will seriously endanger human health and even cause cancer. Scientific research shows that drinking water contains minerals and traces of harmful heavy metal ions such as cadmium, mercury, and arsenic. When the water is heated, as the water temperature rises, the solubility of certain calcium and magnesium ions decreases, and the concentration of hardly soluble salts continuously increases. When the water is concentrated to a certain degree, the precipitate precipitates. These precipitates can enter tea cups as water is brewed. Teas that have not been consumed or left for a long period of time are exposed to the air. Tea polyphenols and tea rust metal elements are oxidized and produced. Brown tea rust, commonly known as tea scale, adheres to the inner wall of the cup. Tea rust contains various harmful metals such as cadmium, lead, mercury, and arsenic, which are the chief culprits of harm to human health. Long-term cups stained with tea can cause cancer Tea scale contains toxic substances such as cadmium, lead, mercury, and arsenic, as well as carcinogens such as nitrite, which adhere to the smooth surface of the tea cup. As drinking tea enters the body and enters people's digestive system, it combines with proteins, fatty acids, and vitamins in foods to produce insoluble precipitates that not only hinder the absorption and digestion of these nutrients, but also cause the stomach and other organs to be affected. damage. In addition, tea cups that are often not washed still leave more scale, which also contains a large amount of heavy metals, which is extremely detrimental to health. At the same time, these oxides can cause nervous, digestive, urinary and hematopoietic disorders and dysfunction, and even lead to premature aging. In particular, arsenic and cadmium can cause cancer, cause fetal malformation, and endanger health. How to thoroughly wash off the tea dirt The thicker the tea scale, the harder it is to clean, so daily cleaning and regular cleaning are equally important. Experts suggest that individuals should carefully clean their tea after each tea session, even if they do not leave obvious tea stains. 1. Add water to the teapot or teacup, add potato skin, heat and boil, rinse after cooling, and it is easy to clean. 2. When using a metal tea cup, it will become black due to tea scale. If it is washed with medium-sized detergent, it can be soaked in vinegar, or it can be easily descaled after bleaching. 3. Apply edible salt on the inside, especially where tea stains are found. Then brush the cup firmly with a toothbrush and rinse it with clean water. 4. The tea scale has been deposited for a long time and is not easy to clean. Use heated rice vinegar or soaked in baking soda for a day and night, and then use a toothbrush to wash easily. It should be noted that if you use a teapot, you do not need to clean it. The teapot itself has pores, and the minerals in tea scale can be absorbed by these pores, which can play a role in maintaining the pot, and it will not cause harmful substances to “run†into the tea water and be absorbed by the body. 5. Put a teaspoon of orange juice or orange juice in the teacup or teapot. Fill with clear water for 2-3 hours. Tea scale and tea utensils lose their adhesive strength and are easily removed. Experts specifically reminded that when removing tea scales, it is best not to use scrubbing tools such as steel balls or cleaning balls to scrub, because these brushing tools can easily damage the enamel on the inner wall of tea ware, making it thinner and thinner, and the resulting tea Scale can easily penetrate deep into the tea set and it is extremely difficult to completely remove. Individuals should use a small soft brush or toothbrush, a soft cleaning cloth to clean. It is best to brew only once for bagged tea and 3 times for bulk tea In addition to tea scale is not clear and harmful to health, the tea brewing only the most nutritious, most healthy? Many people are not clear. Some people in life like to brew tea repeatedly until they can't taste. Some people rush to change tea once or twice. Which of these two methods is correct, it is better to brew a cup of tea several times? Some people like to drink light tea, some people like to drink strong tea, although the number of tea brewing and different people's tastes have a lot to do, but from In terms of nutrient absorption, it is best to brew tea bags only once, and bulk teas do not exceed 3 times. Tea contains tea polyphenols with anti-cancer effects, tea polysaccharides that can lower blood sugar, caffeine that stimulates the central nervous system, and many nutrients such as amino acids and vitamins. How much of these nutrients can be precipitated has a great relationship with the number of brewing times. In general, the greater the size of the tea leaves, the slower the release of nutrients; the smaller the particles, the faster the rate of precipitation. Compared with bulk tea, packed tea leaves are cut and kneaded during processing to fully destroy the leaf cells. The shape of the particles is relatively small. The nutrients in the tea leaves are soaked for the first time in 3-5 minutes. % - 90% precipitation, after the second brewing, the remaining 10% of the nutrients are almost all precipitated. Therefore, Yin Junfeng suggested that it is best to brew tea bags once, not only in the absorption of nutrients, but also not affect the taste and taste. Because of the large size of the bulk tea, the first brewing time is preferably a little longer. It should be about 5 minutes, and 60%-80% of the nutrients will be released. After the second brewing, there will be 80%- After 90% of the nutrients have been released for the third time, the leaching rate of nutrients will exceed 95%, and the brewing will be no longer a nutrient. As some experts pointed out that tea brewing many times will lead to the leaching of harmful substances such as pesticides and heavy metals. Yin Junfeng said that although there is some truth in this argument, it does not have to worry too much. At present, most of the pesticides used in tea production in China have very low water solubility. According to the calculation of 10 grams of tea per person per day, even if the tea is brewed with 1 mg/kg of residual tea, only 0.0001 mg of pesticides are ingested, which is allowed by the World Health Organization. Thousands of intakes. The leaching rate of lead in heavy metals in tea is also relatively low, as long as the regular factory tea is purchased, its content will not exceed the national standard. Drinking tea: 12 grams a day is the most suitable for ordinary people, about 12 grams of tea a day, 3 to 4 times brewing is appropriate. People who eat more greasy food and have a large amount of tobacco and alcohol can increase the amount of tea. Pregnant women and children, neurasthenia, tachycardia, the amount of tea should be reduced. With the popularity of Kung Fu tea, people are becoming more and more hot when they drink tea. This is very wrong. People drink tea as health care, but drinking hot tea increases the incidence of cancers such as esophageal cancer, which is not worth the candle. The best temperature for drinking tea should be about 60 °C, do not exceed 70 °C. In addition, you can drink different teas at different times of the day: In the morning, have a light green tea to refresh your mind. In the morning, you can have a tea in the morning. It is fragrant and pleasant, which can increase work efficiency. In the afternoon, you can enjoy a cup of black tea and refresh yourself; Reunite the family and soak in a pot of oolong or pu-erh. Do not have a taste or affect sleep. Infusion And Syringe Pump,Pet Syringe Pump,Medical Vet Syringe Pump,Vet Pet Syringe Infusion Pump Medton Medical , https://www.medton.cn
