What are the benefits of drinking black tea regularly?

In China, drinking tea is a life style, an art, a knowledge and an indispensable part of traditional culture. Refers to tea making, it is a really complicated process. According to the degree of fermentation, rolling, baking and tea leaf maturity, it is roughly divided into four categories: non-fermented, post fermented, partially fermented, and complete fermentation. Most people prefer green tea rather than black tea. Because black tea seems to be too bitter in taste, lacking a refreshing feeling. However, it is fully fermented, and it is featured as a heavy taste. Due to its benefits, it is particularly suitable for drinking in fall and winter.
1. What is the difference between black tea and green tea? One may feel discomfortable when he drinks too much green tea on an empty stomach. The reason lies in the convergent tea polyphenol that can stimulate our stomach. So we may feel worse to drink it on an empty stomach. For fully fermented black tea, it is a completely different story. Its polyphenol content will decrease under the enzymatic oxidation. Thus, its irritation on the stomach will reduced greatly along with it. In addition, oxidative products of these polyphenols can also accelerate the digestion and nourish the stomach. Regular intake of it can remove inflammation, protect the gastric mucosa, but also have certain effect on treating the ulcers.
2. Antioxidant and anti-aging. It has been confirmed that the antioxidants in tea can affect the spread of cancer cells. The magic of tea is roughly similar. Yet, the antioxidants in black tea are much more complex than green tea. Particularly, it is beneficial to maintaining the heart health. It is reported that the anti-aging effect of black tea is stronger than that of garlic, broccoli and carrot.
3. Due to its efficacy of causing diuresis and detoxifying, it can protect people from the industrial pollution. The caffeine and aromatic substances in black tea can help increase renal blood flow, improve the glomerular filterability, dilate the renal microvasculature, and inhibit tubular reabsorption of water, thus causing diuresis. Thereby, it is beneficial to clearing away lactic acid and uric acid(related to gout), excessive salt (associated with hypertension), and harmful substances as well as relieving the edema caused by heart disease or nephritis. It has been proved that tea polyphenol in black tea can absorb, precipitate, and decompose heavy metals and alkaloids. For us who are living with various pollutions, it is really good news.
