The efficacy of oolong tea Green tea and oolong tea are produced by the same kind of tea tree. The biggest difference is whether it has been fermented or not. Because the catechins in tea will combine with each other with the increase of fermentation temperature, the color of tea will become darker, but the astringency of tea will also decrease. The components formed by the combination of catechins are polyphenols of oolong tea. Polyphenols and catechins with antioxidant effects can affect the activation of various enzymes in our body. About half of catechins in tea will be converted into polyphenols in oolong tea. Therefore, under the dual effects of catechins and oolong tea polyphenols, oolong tea shows various effects that green tea does not have. The effects of oolong tea are as follows: 1, prevention of tooth decay: After a meal, a cup of tea can not only produce saliva, but also refresh the breath. Oolong tea also has the effect of preventing tooth decay. The cause of tooth decay is that bacteria invade the tooth tissue and produce enzymes in the tissue that cause tooth decay. This enzyme reacts with the sugar contained in food to produce substances that decay teeth. This substance and bacteria that can decay teeth attach to the teeth to form dental scale, and after accumulation, tooth decay will occur. Polyphenols contained in oolong tea can inhibit the production of tartar enzymes, so drinking a cup of oolong tea after eating can prevent the occurrence of tartar and tooth decay. Scientists have proved through long-term experiments that letting white rats eat feed containing polyphenols will reduce the probability of tooth decay. If there is no time to brush their teeth after meals, it is also a good choice to drink a cup of oolong tea to prevent tooth decay. 2. Eliminate reactive oxygen species that are harmful to beauty and health: reactive oxygen species are substances produced in the body due to ultraviolet rays, smoking, food additives, stress and other factors. It changes the fat in the body into peroxide fat, which causes the occurrence of lifestyle diseases and hinders health. At the same time, reactive oxygen species can also cause skin aging, wrinkles and a series of problems that hinder beauty. In human body, there is an enzyme SOD which can successfully decompose reactive oxygen species. This enzyme is an indispensable substance to maintain health and beauty beauty. The polyphenols of oolong tea have the same function as SOD, and can promote the function of SOD to eliminate reactive oxygen species. We all know that the growth of skin needs vitamin C. If reactive oxygen species are produced, vitamin C will be consumed. The antioxidant effect of oolong tea polyphenols can eliminate reactive oxygen species and then inhibit the consumption of vitamin C, so it can keep the skin delicate and white. In addition, oolong tea itself contains vitamin C, which can kill two birds with one stone for whitening skin. Vitamin C will be excreted with urine in about 2-3 hours. Therefore, drinking oolong tea at any time can whiten skin and ensure vitamin C supplementation. 3. Drinking 1 liter of oolong tea every day can improve skin allergy: some surveys show that most people suffer from allergic dermatitis in skin diseases, but the cause of this dermatitis is not clear so far. However, oolong tea has the effect of inhibiting the development of the disease. The experiment of making skin inflammation symptoms in white mice proves that oolong tea has an inhibitory effect on dermatitis in white mice. An expert abroad once found that 12 1 adult patients with allergic dermatitis were treated with existing steroids and antiallergic drugs, but they still could not improve their condition. Later, after drinking 400ml of concentrated oolong tea every day, after a month, 78 of them (accounting for 64%) showed obvious improvement in symptoms. 4, drinking oolong tea can lose weight: We often hear that drinking oolong tea can "dissolve fat". Especially after eating too much greasy food, drinking oolong tea can decompose oil, so is this statement correct? The unconsumed energy in human fat cells is stored as neutral fat so that it can be used as energy during exercise. At this time, neutral fat is decomposed into necessary energy for use under the action of enzymes such as protein-like lipase. Drinking oolong tea can improve the function of protein-like lipase. That is to say, oolong tea itself can not dissolve fat, but it can improve the enzymes that decompose fat, so after drinking oolong tea, the amount of fat metabolism is also relatively increased, thus playing the role of slimming. Some experts once experimented on drinking oolong tea with simple obese adults *** 102, and drank 300cc of oolong tea twice in the morning and afternoon, 600cc a day for 6 weeks. In the meantime, no other weight loss or food therapy was used. Results No significant weight loss was found, but their waistlines, abdominal subcutaneous fat, blood neutral fat and total blood cholesterol all showed a significant decreasing trend, and this effect was due to the polyphenols contained in oolong tea. 5, anti-tumor, anti-aging effect: oolong tea has the effect of promoting the decomposition of blood fat, but also reduce the cholesterol content. An experimental report on the efficacy of oolong tea in foreign countries 1994 pointed out that oolong tea has quite good curative effect on patients with hyperlipidemia and hypertension. Especially, among the 68 patients with Gao Xue's hypertension who participated in the trial, after one stage of testing, 75% of them showed a downward trend in blood pressure. In addition, oolong tea also has the functions of anti-tumor, improving the activation of lymphocytes and NK cells, strengthening immune function and preventing aging. Experts have found that oolong tea polyphenols also have the effect of absorbing foreign bodies in the body and expelling them together. For so many amazing effects of oolong tea, experts point out that the amount of oolong tea that can produce effects is about 1 liter per day. If it can't reach this amount of 1 liter, you should brew strong oolong tea to drink, so as to get enough polyphenols. In addition, it should be noted that it is unscientific to drink a large amount of oolong tea once a day. The correct method should be to drink oolong tea several times a day, so that the polyphenols in oolong tea can be fully absorbed by the human body. Also, you should get into the habit of drinking a cup of oolong tea after meals. Thank you, I hope to adopt it.
