Foreigners like to drink coffee, while Chinese people prefer tea. Tea can be divided into two broad categories, one is black tea, the other is green tea. Whether it's black tea or green tea, tea is rich in nutrients.
In particular, tea polyphenols, with super clear free radical function, women often drink tea, not only can effectively help resist the radiation caused by electronic products, but also emollients, beauty, anti-aging.
Beautifying effect of tea polyphenol
1. Absorb ultraviolet rays to prevent sunburn
Free radicals are an important factor in aging, and UV is the main source of skin free radicals, tea polyphenols can directly absorb ultraviolet radiation, so tea polyphenols can directly prevent UV damage to the skin. Tea polyphenols, known as "UV" filters, are the largest effective protective agent for the skin.
2, antioxidant, anti-aging
Tea polyphenols have the effect of scavenging free radicals, can inhibit the skin line three-dimensional lipoxygenase and lipid peroxidation, can prevent wrinkles, anti-aging.
The results showed that the antioxidant activity of tea polyphenols was obviously better than that of vitamin E, and it had synergistic effect with vitamin C and E.
3, inhibit melanin, beauty skin care
Tea polyphenols are water-soluble substances, with its face wash can clear the face of greasy, astringent pores, with disinfection, sterilization, anti aging skin and other effects.
Tea polyphenols can block UV and eliminate UV induced free radicals, thus protecting the normal function of melanocytes and inhibiting the formation of melanin. At the same time, it can inhibit lipid oxidation and lighten pigmentation.
4 kinds of tea rich in tea polyphenols
1, green tea: natural tea polyphenols are the most
All tea contains polyphenols from tea varieties and the production process, the polyphenol content of Green Tea is the highest, because the production of polyphenols Green Tea, almost no oxidation process, retained.
Green tea contains a large amount of tea polyphenols, can effectively prevent radioactive substances invading the bone marrow, and can make strontium and cobalt rapidly discharged in vitro, health and medical circles as "radiation nemesis."".
Green tea has more tannin content than other teas, 15%~20%. Inhibits the generation of lipid peroxides that cause aging. Inhibition of cell cancerization, can reduce blood pressure and blood sugar.
2 Tieguanyin tea: rich in polyphenols, but also fat burning thin
Tieguanyin also contains a large number of tea polyphenols, can improve the role of fat degrading enzymes, reduce blood cholesterol content, have lower blood pressure, antioxidant, anti-aging and anti-cancer effect.
Moreover, compared with the Black Tea Tieguanyin and Green Tea, in addition to the stimulation of pancreatic lipase activity, reducing sugars and fats are absorbed from outside, also can accelerate the body heat production increase, promote fat burning, especially to reduce abdominal fat accumulation.
3, Pu erh tea: after oxidation, tea polyphenols are easy to absorb
Some experts believe that polyphenols can be beneficial to human body after oxidation, so we should take the oxidized tea polyphenols instead of fresh tea polyphenols.
The transformation process Pu'er Tea quite unique, mainly rely on natural storage make contact with oxygen to make tea, tea polyphenols were slowly oxidized, so as to maximize the retention of the tea polyphenols was not damaged, so the old Pu'er tea effect than other kinds of tea are many times higher.

4, Black Tea: tea polyphenols after fermentation, can stomach
Tea polyphenols have astringency, have certain stimulation to the stomach, and stimulate more in the condition of fasting. The Black Tea is fermented baked, tea polyphenol oxidase in under the action of the enzymatic oxidation reaction, reducing the content of stomach irritation decreases.
The oxidation products of tea polyphenols can also promote digestion, so Black Tea not only does not hurt the stomach, but can stomach. Regular use of black tea with sugar and black tea with milk can reduce inflammation, protect gastric mucosa, and have some effect on the treatment of ulcers.
