Don't use freshly boiled water to brew tea
Nutrition: Tea is very nutritious, containing more than 300 different components, such as theine, theobromine, crude fiber, pectin, chlorophyll, vitamin A precursor, vitamin B precursor, vitamin P, vitamin C, and small amounts of various amino acids, as well as large amounts of potassium, magnesium, calcium, phosphorus, and various trace elements. It also contains "tea tannin" with rutin-like activity, all of which are beneficial nutrients for the human body.
Experts say that drinking tea can lower blood lipids, cholesterol, and high blood pressure, and reduce the incidence of arteriosclerosis and coronary heart disease. The polyphenols in tea are a powerful antioxidant that can have anti-aging effects. In addition to detoxifying, hemostatic, and antioxidant properties, tea tannin also has anti-cancer effects. Long-term tea drinking can effectively inhibit bladder cancer, kidney cancer, and liver cancer.
Furthermore, the carotene in tea can increase the concentration of carotene in the plasma and reduce the incidence of senile cataracts. Gargling with strong tea regularly can also prevent mouth ulcers, so it might be worth a try for those who smoke frequently and experience oral mucosal breakdown.
Green tea is the finest of teas, with a high content of folic acid that can prevent anemia, and the fluorine in tea can effectively prevent cavities. Black tea, on the other hand, is fermented during the drying process, so its color is dark, and its content of vitamin C and tannin is greatly reduced, but it has the effect of warming the stomach and dispelling cold.
Hazards: Drinking too much tea can lead to adverse reactions such as over-excitement, rapid heartbeat, insomnia, and frequent urination. Moreover, due to excessive loss of urinary calcium and excessive irritation of the gastric mucosa, long-term consumption of strong tea can easily lead to osteoporosis and gastric ulcers.
For office workers, adequate sleep is very important. Drinking too much tea before bed can make the mind too alert to fall asleep, affecting rest. In addition, preschool children, people with iron-deficiency anemia, neurasthenia patients, patients with active gastric ulcers, people with poor liver function, constipation sufferers, those with urinary tract stones, breastfeeding women, patients with acute episodes of heart disease, and pregnant women are all not very suitable for drinking tea. Heartwarming tip:
Don't use a thermos to brew tea, because tea contains various vitamins and aromatic substances that will be greatly reduced under high temperature and constant temperature, making the brewed tea too astringent. Also, don't use freshly boiled water to brew tea, or brew the tea in a filter, otherwise the rich vitamins and minerals in the tea will be lost.
