Green tea and oolong tea from a tea produced by the same people.  The biggest difference is that there has not been the fermentation process.  Catechins in tea because the fermentation temperature will be a combination of the increase, which change the color of deep tea, but tea Semei therefore will be reduced.  This catechins formed by the combination of ingredients is the Oolong tea polyphenols.  Polyphenols with antioxidant and the role of catechins, can affect the enzymes in our body of the activity.  Tea catechins contained in about half will be translated into the tea polyphenols.  Therefore, the antioxidant effect of catechin and Oolong tea polyphenols such dual role, shows that the green tea, oolong tea on the effectiveness of the various not.
 The effectiveness of oolong tea is as follows:
 1, the prevention of tooth decay:
 In addition to the meal a cup of tea-only grams of Health, the tone of cool, oolong tea is also available in the effectiveness of the prevention of tooth decay.  The causes of tooth decay is due to bacterial invasive dental organizations, but also within the organization have caused tooth decay enzymes, such enzymes in the food and the presence of sugar play a role, very much a dental material.  This can be very much dental material and bacteria attached to the gear teeth that is a scale that will take place after the cumulative decay phenomenon.
 Oolong tea polyphenols found in a tooth can inhibit the enzyme scale efficacy, so after dinner to drink a cup of tea, can prevent tooth decay and the occurrence of scale.  Scientists prove a long-term experiment, rats eating feed containing polyphenols will reduce tooth decay in the table, if there is no time to brush their teeth after meals, in order to prevent tooth decay drinking a cup of oolong tea is a good choice.
 2, to eliminate the hazard of beauty and health reactive oxygen species:
 ROS is due to UV, smoking, food additives, stress factors such as the substances in the body.  It will be adopted by the body fat change fat into peroxide, which led to the formation of habits, and hinder good health.  At the same time, reactive oxygen species also cause skin aging, such as wrinkles produced a series of problems impede beauty.
 In the human body there is a decomposition of reactive oxygen species can successfully enzymes SOD, this enzyme is to maintain limits and beauty Yangyan essential substances.  And Oolong tea polyphenols have the same function and SOD and SOD can promote the elimination of reactive oxygen species function.
 We all know that the growth of skin need vitamin C, if they have active oxygen, vitamin C will be depleted.  Oolong tea polyphenols and antioxidant role of the category because it can eliminate active oxygen, thereby inhibiting vitamin C consumption, it can be maintained meticulous skin whitening.  Oolong tea itself with vitamin C containing the composition of the skin whitening, it is double benefit.  Vitamin C in about 2-3 hours will be excreted with urine, therefore, ready to drink tea can whitening can ensure that supplements of vitamin C.
 3, drank a litre of tea every day can improve skin allergies:
 Surveys show that: suffering from skin diseases in patients with allergic dermatitis in the number of the majority, but so far this kind of the causes dermatitis also is not clear.  However, oolong tea has the effect of inhibiting the development of illness.  Manufacturing in rats through skin irritations experimental evidence that tea dermatitis white mice with the restraining effect.
 An expert from abroad has been adopted by the 121 people with allergic dermatitis adult patients for clinical trials found objects, they are using the existing category of steroids and allergy drug treatment, but it can not improve conditions until later and 400 ml drinking on the day of concentrated tea, after a month, and 78 of them (64%) of the patient's symptoms appeared significantly improved.
 4, drinking tea can thin:
 We often can be heard to drink tea "dissolved fat."  Especially eating too much greasy food, drink tea can decompose oil, then this view is correct?  The fat cells, not the consumption of energy, being used as a neutral fat to be stored for use as a source of energy during exercise.  This time, neutral fat in fat enzyme protein enzyme type role, is broken down into the necessary energy to use.  Drinking tea can upgrade of the function of protein lipase.  In other words, not tea itself can be dissolved fat, but it can improve an enzyme decomposition fat, drinking tea, fat metabolism was also improved relative to the downsizing has played a slimming effect.
 Some experts had the simple total of 102 obese adults who drink tea experiment, the morning and two in the afternoon of tea drinking 300 cc, 600 cc of the day, sustained six weeks.  Which do not use food or other weight loss therapies.  Results found no weight decreased, but their waist circumference, abdominal subcutaneous fat, blood neutral fat, total blood cholesterol are in the final shown a trend of smaller, and this effect is more from the tea contains polyphenols drive.
 5, anti-tumor and prevent aging effects:
 Oolong tea is to promote decomposition of the effectiveness of fat in the blood, can also reduce the cholesterol content.  A 1994 foreign oolong tea effectiveness of the report, oolong tea for high blood lipid disease and hypertension patients have a fairly good effect.  Especially in participating in the trial of 68 patients with high snow pressure, through a phase of the test, from 75 per cent of the blood pressure values on a downward trend.
 In addition, oolong tea also have anti-tumor, and improve lymphocyte activation of NK cells, as well as to strengthen immune function, role in the prevention of aging.  Oolong tea polyphenols experts have found the body of sorption are together from the foreign body and its in vitro effect.
 Oolong tea for so many astonishing effect, the experts pointed out: the effectiveness of weight can have every day about 1 litre of drinking tea, if it is not possible to achieve a litre this weight, thick enough to be brewing tea drinking, be getting enough polyphenols.  In addition, we must pay attention to, a one-off one day drinking a lot of tea is unscientific and correct approach should be one of the scores of drinking tea, so that it may be oolong tea polyphenols in the full absorption by the body.  Also, the meal should cultivate the habit of drinking a cup of tea.
