First, Pu 'er tea is mild and does not hurt the stomach. Modern people have a stressful life, great pressure, common stomach diseases, deficiency of qi and blood, and abnormal diet. Generally speaking, for tea lovers, light fermented tea really has the scruples of "unbearable lightness".
2. Pu 'er tea is a healthy drink with scientific basis. Modern people "make money with their lives" abound. After the anti-cancer and health-care function of Pu 'er tea was confirmed by the medical profession, the concept of "keeping a long life with little money" not only strengthened the belief of tea lovers, but also attracted many new tea friends. In addition, the pharmacological characteristics of Pu 'er tea, such as removing fat, promoting digestion, reducing weight and slimming, have swept the hearts of countless beauty-lovers and middle-aged and elderly people.
Thirdly, Pu 'er tea is easy to brew, foam and operate. Properly aged Pu 'er tea is not bitter or astringent. Even if it is soaked for a long time, it can enter the throat. It doesn't need to compare notes like alpine tea, but it has the fun of tea, even without losing the convenience of tea bags.
Fourth, Pu 'er tea is easy to preserve and its tea quality is changeable. In a certain definition, Pu 'er tea is a "living organism", which is mainly characterized by continuous "post-fermentation" (or post-ripening aging) after the tea body is completed. With the extension of time, its flavor transformation becomes more stable and restrained. Tea bodies in different aging periods have different flavors, which is also tea tasting. Tibetan tea people participated in the "production and completion of tea" to a certain extent.
5. Pu 'er tea is a drinkable antique. Few drinks or foods have the dual characteristics of "drinkable and storable" Pu 'er tea, that is, "everyone can drink it, and the older it gets, the more expensive it becomes". The new Pu 'er tea is everyone's daily drink, while the old Pu 'er tea is "equal in price and gold", which is beyond our power. If it is the "collection value" at the left end of the "Pu 'er balance", it is the "durable wealth" that only rises but does not fall. On the other hand, the right end is the "drinking value", which is the "consumption wealth" of drinking less, and "time" is the "weight" between the two. As the weight of time moves to the left, the higher the collection value of this cake tea, and vice versa. The collection of Pu 'er tea in the distance is similar to that of red wine. Both pay attention to the year, place of origin (winery, teahouse), rarity and preservation.
green tea
1. Green tea anti-aging
Antioxidants contained in green tea help to fight aging. Because in the process of human metabolism, if it is over-oxidized, it will produce a lot of free radicals, which are easy to age and cause cell damage. SOD (Superoxide Dismutase) is a kind of free radical scavenger, which can effectively remove excess free radicals and prevent the harm of free radicals to human body. Catechins in green tea can significantly improve SOD activity and scavenge free radicals.
2. Green tea is antibacterial
Studies have shown that catechins in green tea can inhibit some bacteria that cause human diseases without harming the proliferation of beneficial bacteria in the intestine, so green tea has the function of whole intestine. Studies have shown that tea polyphenols can eliminate excessive harmful free radicals in the body, regenerate efficient antioxidant substances such as α-VE, VC, GSH and SOD in the human body, thus protecting and repairing the antioxidant system, which has a significant effect on enhancing immunity, preventing cancer and preventing aging. Drinking green tea for a long time can reduce blood sugar, blood lipid and blood pressure, thus preventing cardiovascular and cerebrovascular diseases. The medical research team of Showa University in Japan diluted 1 ml tea polyphenols solution to 1 of the concentration of ordinary tea, and put it into 10000 highly toxic Escherichia coli 0- 157. Five hours later, all the bacteria died, leaving none.
3. Green tea lowers blood fat
Animal experiments made by scientists show that catechins in tea can reduce total cholesterol, free cholesterol, low-density lipoprotein cholesterol and triglycerides in plasma, and at the same time increase high-density lipoprotein cholesterol. Human experiments show that it can inhibit platelet aggregation and reduce the incidence of arteriosclerosis. Green tea contains flavonol, which has antioxidant effect, prevents thrombosis and platelet aggregation, and reduces cardiovascular diseases.
4. Green tea slimming and fat reduction
Green tea contains theophylline and caffeine, which can activate protein kinase and triglyceride lipolytic enzyme through multiple functions, reduce the accumulation of fat cells, and thus achieve the effect of losing weight.
5. Green tea can prevent dental caries and remove bad breath.
Green tea contains fluorine, in which catechins can inhibit the action of cariogenic bacteria and reduce the occurrence of dental plaque and periodontitis. Tannic acid contained in tea has bactericidal effect, which can prevent food residues from breeding bacteria, so it can effectively prevent bad breath.
6. Green tea can prevent cancer
Green tea can inhibit some cancers, but its principle is limited to the inference stage. Drinking more tea is bound to have a positive encouraging effect on preventing cancer.
7. Whitening and UV protection of green tea
Experts found in animal experiments that catechins in green tea can resist skin cancer caused by UV-B.
8. Green tea can improve indigestion.
Recent research reports show that green tea can help improve indigestion, such as acute diarrhea caused by bacteria, and drinking a little green tea can alleviate the condition.
