Health care: Black tea can help digestion, stimulate appetite, induce diuresis, eliminate edema and enhance myocardial function. Disease prevention: black tea has strong antibacterial ability. Gargling with black tea can prevent colds caused by viral diseases, prevent tooth decay and food poisoning, and reduce blood sugar and hypertension. Studies show that black tea is not worse than green tea, and it is more beneficial to the heart. According to the International Herald Tribune reported on July 28th, as we all know, drinking green tea has a good health care effect on human health, helps to prevent the recurrence of heart disease, reduces the infectivity of viruses and bacteria, and plays an important role in preventing prostate cancer, breast cancer, gastric cancer and colon cancer. In fact, the efficacy of black tea is not worse than that of green tea, and black tea is more conducive to heart health. In the past five years, the US government has funded more than 65,438+050 studies on green tea and black tea and their chemical compositions. The results show that antioxidants in green tea and black tea can completely destroy the transmission path of chemicals in cancer cells. Dr Murray Mitelman, director of vascular epidemiology at Beth Israel Deaconess Medical Center in Boston, said, "Black tea has roughly the same efficacy as green tea, but the antioxidants in black tea are much more complicated than green tea, especially beneficial to the heart." . On May 3, 2002, the American Medical Association published a survey report, and 497 men and 540 women were followed up for more than 10 years. The report pointed out that people who drink black tea have strong bones, and polyphenols in black tea (also found in green tea) have the activity of inhibiting bone cell destruction substances. If lemon is added to black tea, the bone strengthening effect will be stronger. In addition, half an hour before meals and one hour after meals are the best time.
