Dr. Murray Mittel, director of vascular epidemiology at the Beth Israel Deaconess Medical Center in Boston, said: “The efficacy of black tea and green tea is roughly the same, but black tea antioxidants are much more complex than green tea, especially for the heart.†.
3, Yangwei Huwei: gastrointestinal bad people are generally afraid to drink tea, because the tea polyphenols have astringent, have a certain stimulating effect on the stomach. Because black tea is a fully fermented tea, tea polyphenols are much less than green tea, and they are naturally less irritating to the stomach.
