Is there any harm for women to like tea?

Women drinking tea is harmless, healthy and reasonable. Drinking tea in moderation is good for the skin, especially in winter, and it is good for preventing skin itching. This is because the insert is rich in trace element manganese. Many plant foods contain manganese, such as Chinese cabbage, spinach and soybean, but the content of manganese in tea is the highest. Black tea contains the most manganese per gram 1280 g, and green tea contains the most manganese per gram 1080 g. Manganese is one of the essential trace elements in human body, which is distributed in various tissues of human body. Manganese can participate in a variety of enzymatic reactions, promote the metabolism of protein, improve the absorption and utilization of protein, and promote the excretion of some substances harmful to the skin produced by the decomposition of protein, thus reducing the adverse stimulation to the skin. According to research, manganese can also enhance the activity of some enzymes, catalyze the metabolism of some vitamins in the body, ensure the normal metabolism of sebum and prevent dry skin; At the same time, manganese can also promote the accumulation of vitamin B6 in the liver to strengthen the anti-dermatitis function of the human body. Therefore, in the cold and dry season, drinking tea regularly is a simple way to increase the manganese content of human body and prevent skin itching. Moderate drinking tea has no effect on skin color. In addition, according to a study by the University of Arizona, drinking strong hot black tea can reduce the risk of squamous cell skin cancer. According to the American Cancer Society, the study, completed by the University of Arizona School of Medicine, was the result of comparing 234 skin cancer patients who used to drink tea with 2 16 people who used to drink tea and had no skin cancer. The results were published in the Journal of Cancer Epidemiology. The two groups drank the same amount of strong tea, but the cancer-free group drank stronger hot black tea, while the two groups also drank the same amount of iced black tea and light black tea. Because most Americans drink black tea more often, green tea is not in the sampling range of this study. The results of the study finally found that the experimental group without cancer drank strong tea and hot tea, and they usually soaked the tea for 7 minutes, at least 2 to 3 minutes before drinking. Although tea is the most common thirst-quenching drink except water since ancient times, few people know its exact health care effect. The research team of the University of Arizona pointed out that the study did not fully establish the relationship between tea and cancer, and the study itself had many limitations. However, this study did find that polyphenols in tea can hinder the expansion of cancer cells. It is found that the chemical elements contained in tea are easily lost in iced tea because they will precipitate to the bottom of the container at low temperature. The research team said that they need to further confirm the relationship between drinking tea and skin cancer, and also need to study the relationship between drinking tea and other cancers. Oncologists of the American Cancer Society pointed out that if the results of this study are confirmed, it will help to reduce the number of cases of skin cancer, but the most important thing is to remember not to be overexposed to the sun, because overexposure is the main risk factor for skin cancer. About the amount of drinking: the amount of drinking tea depends on drinking habits, age, health status, living environment, customs and other factors. Generally healthy adults have the habit of drinking tea. They drink about12g of tea a day, and it is advisable to brew it 3-4 times. For people who work hard, consume and eat a lot, especially those who are exposed to toxic substances in high temperature environment, it is also appropriate to drink about 20 grams of tea every day. People with more greasy food and a large amount of tobacco and alcohol can also increase the amount of tea appropriately. Pregnant women and children, neurasthenia, tachycardia, should be appropriate to reduce the amount of tea. About not drinking tea after meals: drinking tea immediately after meals will dilute gastric juice and affect food digestion. At the same time, tannic acid in tea will solidify the substances in food, increase the burden on the stomach and affect the absorption of protein. It is best to drink tea one hour after dinner.
