Medical researchers in China claim that oolong tea can reduce weight. The popularity of oolong tea is entirely due to its fat-dissolving and slimming effect, and this statement does have scientific basis. Because tannic acid, the main component of tea, is proved to be closely related to fat metabolism, and the experimental results also confirm that oolong tea can really reduce the cholesterol content in the blood, so it is a rare slimming tea. Experiments show that drinking one liter of oolong tea every day can inhibit the rise of cholesterol. The amount of drinking depends on everyone's physical condition. When the food is too greasy, it can also be paired with oolong tea, which will make you feel full and remove greasy.
Health function

2. Drinking 1 L oolong tea every day can improve skin allergy;
3. Drinking oolong tea can slim down;
4. Anti-tumor and anti-aging effects.
I have long known that tea is magical. Lu Tong, a poet in the Tang Dynasty, described the efficacy of tea in this way: "One bowl moistens the throat, two bowls are lonely and boring, and three bowls are poor, with only 5,000 volumes of words; Four bowls of light sweat, unfair life, scattered to the pores; Five bowls of clear skin; Six bowls of fairy spirits; Seven bowls can't be eaten; I just feel a breeze under my arm. " In the Song Dynasty, Wu Shu's "Tea Fu" said: "It's wonderful for a husband to quench his thirst and turn his bones into light weight, thanks to tea milk." Li Shizhen's Compendium of Materia Medica in the Ming Dynasty said: "Tea tastes bitter and cold, and the yang in the yin will sink, which can best reduce the fire.".
Therapeutic value of drugs
Oolong tea, as a famous tea unique to China, has been confirmed by modern scientific research institutes at home and abroad. Oolong tea not only has the health-care functions of refreshing mind, relieving fatigue, promoting fluid production and diuresis, relieving fever and heatstroke, sterilizing and diminishing inflammation, dispelling cold and hangover, detoxicating and preventing diseases, promoting digestion and relieving boredom, losing weight and keeping fit, but also has the special health-care functions of preventing cancer, reducing blood fat and resisting aging.
1. Anti-cancer1998 On June 5th, 65438, Han Chi, an associate researcher in the Toxicology and Chemistry Research Office of Institute of Nutrition and Food Hygiene, Chinese Academy of Preventive Medicine, and her assistant Xu Yong conducted an anti-cancer experiment of tea on animals. They fed mice five kinds of tea, such as Anxi Tieguanyin, and at the same time, they were fed methyl carbazide glue, a synthetic carcinogen with purity greater than 99.8%. After three months, the incidence of esophageal cancer in rats was 42-67%, and the average number of tumors in rats with cancer was 2.2-3. The incidence of esophageal cancer in rats who did not drink tea was 90%, and the average number of tumors in mice with cancer was 5.2. Five kinds of tea have the best anticancer effect in Anxi Tieguanyin. At the same time, they also conducted another experiment, that is, using sodium nitrite and methyl carrageenan as carcinogenic precursors. The results showed that none of the rats in the tea drinking group developed esophageal cancer, and the incidence rate was 100%. This result proves that tea can completely block the endogenous formation of nitrite nitrogen in the body.
2. Lowering blood lipid 198 1 year, Toyokawa village in Miyagawa, Japan and a male professor in a foreign women's university conducted an experiment on the effect of oolong tea on animal fat metabolism, which proved that oolong tea can significantly inhibit the increase of cholesterol and neutral fat in blood.
From 65438 to 0983, Fujian Institute of Traditional Chinese Medicine observed a group of patients with hypercholesterolemia. When they stopped using all kinds of lipid-lowering drugs, they drank oolong tea twice every morning and evening. After 24 weeks in a row, the blood cholesterol content of patients decreased to varying degrees. Further animal experiments show that oolong tea can prevent and alleviate atherosclerosis of aortic blood lipids. Drinking oolong tea can also reduce blood viscosity, prevent erythrocyte aggregation, improve blood hypercoagulability, increase blood fluidity and improve microcirculation. This is very important for preventing vascular diseases, intravascular thrombosis and traditional Chinese medicine? Quot Blood stasis has positive significance. In addition, in vitro thrombosis test also shows that oolong tea has the effect of inhibiting thrombosis.
3. Anti-aging 1983. The anti-aging experiment conducted by Fujian Institute of Traditional Chinese Medicine showed that the lipid peroxidation in the liver of two groups of animals fed with oolong tea and vitamin E respectively decreased significantly, indicating that oolong tea has the same anti-aging effect as vitamin E. Human experiments also showed that drinking oolong tea can keep the content of vitamin C in blood at a high level and reduce the excretion of vitamin C in urine. The anti-aging effect of vitamin C has long been proved by research. Therefore, drinking oolong tea can enhance the anti-aging ability of human body in many ways.
1985 10 professor Wang Zenong wrote a poem during his inspection in Anxi tea town, which highly summarized the health care efficacy of Anxi oolong tea: Anxi is like the fragrance of Tieguanyin, and six roots prolong life. Huang Jingui, a newly selected famous tea, is a panacea to protect Dan's heart. After serving for thousands of years, it is beautiful, cures all diseases, and is light and light.
Improve listening comprehension.
Experts' latest research found that oolong tea has the functions of beauty, detoxification, laxative, anti-chemical activity and elimination of reactive oxygen molecules in cells. Middle-aged and elderly people often drink oolong tea to help keep their hearing.
After excluding factors such as age, gender, waist circumference and smoking, the researchers found that the participants in the oolong tea group were significantly better than the middle-aged and elderly participants who did not drink oolong tea.
The protective effect on male hearing is obviously greater than that on female hearing. Although drinking oolong tea is good for hearing, you should not drink too much. The daily tea consumption is 1~2 cups.
Weight loss effect
The popularity of oolong tea is entirely due to its fat-dissolving and slimming effect, and this statement does have scientific basis. Because tannic acid, the main component of tea, has been proved to be closely related to fat metabolism, and the experimental results also prove that oolong tea can really reduce the cholesterol content in blood. It is a rare slimming tea made of oolong tea, lotus leaf, hawthorn and other slimming products.
A study published in the Journal of Obesity by Zhang Zhiren, a professor of medicine at the National national cheng kung university in Taiwan Province Province, pointed out that people who regularly drink oolong tea have lower body mass index and fat content than those who drink less. Moreover, women lose weight more effectively than men. Professor Zhang explained that this is because compared with black tea and green tea, oolong tea can not only stimulate the activity of pancreatic lipolytic enzymes and reduce the absorption of sugar and fatty foods, but also accelerate the increase of body heat production and promote fat burning, especially reducing the accumulation of abdominal fat.
Professor Zhang reminds everyone that it is best not to add sugar to hot tea. And don't drink it immediately after meals. It is more appropriate to drink it every 1 hour. Drinking tea should also adapt to personal physique. If you feel uncomfortable after drinking tea, such as stomachache or insomnia, you'd better stop. When making tea, the water temperature should be controlled at about 80℃-90℃; The brewed tea should be drunk within 30-60 minutes, otherwise the nutrients in the tea will be oxidized.
Drinking one liter of oolong tea every day can inhibit the rise of cholesterol. Although the amount to drink depends on everyone's physical condition, when the food is too greasy, it is best to match oolong tea, which will not only make you feel full, but also remove greasy.
Three taboos for drinking alcohol
oolong
Drinking oolong tea is not only beneficial to human health, but also adds endless fun. But there are three taboos:
First, don't drink on an empty stomach, or you will feel hungry. People call it "tea drunk".
Second, don't drink before going to bed, otherwise it will be difficult to fall asleep;
Third, if you don't drink herbal tea, it will be cold after cooling, which is not good for your stomach.
These three taboos are especially important for people who are new to oolong tea, because oolong tea contains more tea polyphenols and caffeine than other teas.
Drinking method
Oolong tea is one of the six major teas in China, and it is called special tea. Therefore, it is known as a wonderful flower in China tea industry. Its fragrance floats all over the world and enjoys a good reputation on five continents. With the sweetness of black tea, the freshness of green tea and the fragrance of scented tea, it is deeply loved by consumers. Drinking oolong tea can not only quench your thirst, but also be an artistic enjoyment. There are three elements in the brewing technique of oolong tea, namely, water for making tea, tea-making utensils and brewing techniques, and the principle that "water is better with stone springs, stoves are better with charcoal fire, and tea sets are bigger with small ones" has been mastered, and Chaozhou Kung Fu tea set is the most representative tea set.
tea boiled water
Since ancient times, people who are good at drinking tea have placed famous tea and good water in the same important position, and compared and tasted them. The relationship between tea and water is like safflower and green leaves. Fish move in water, and tea is brewed with water. Precious tea, without sweet water, is difficult to exert its unique fragrance and taste. So in the Song Dynasty, Wang Anshi said that "water is sweet and tea is fragrant", and Jong Li also said that "Shirley tea smells different". Water includes spring water, river water, well water, lake water, rain water, snow water and tap water. Different water quality makes different teas. The Book of Tea talks about water, saying that "above the mountains and rivers, in the river and underground" is quite reasonable. Generally speaking, mountain spring water, rain and snow water are "soft water", while river water, well water and tap water are "hard water". It is ideal to make tea with flowing natural "soft water" such as spring water and stream water. Secondly, well water and unpolluted tap water can also be used. In short, the water for making tea requires that the water source is free from bacterial pollution and industrial pollution, and the sensory properties of the water are good, that is, colorless, odorless, transparent and odorless, without suspended matter, and the tip of the tongue is cool and sweet. The PH value of water is neutral 7, and the permanent hardness after boiling does not exceed 8 degrees. This kind of water is suitable for making tea.
Tea-making appliance
Famous tea and tea set are always in harmony. Fan Zhongan's "Green dust flies by the Golden Mill, and green jade rises in the center of Osaka"; Mei's "small stone cold spring leaves green flavor, new purple mud blooms in spring", all of which praise the rarity of tea sets to set off the beauty of Jiaming. In history, the tea set for drinking oolong tea is very elegant. There is a small and exquisite tea set called "Four Treasures of Teahouse", that is, the Chaoshan furnace produced in Chaoshan, Guangdong Province-ceramic magnetic wind furnace or tin wind furnace; Yu Shuqian-a flat and light magnetic kettle with a water capacity of about 250ml；; Chen Meng jar-a small purple teapot made in Yixing, Jiangsu Province, with a water capacity of about 50 ml; Ruogenu, a small white porcelain cup produced in Jingdezhen, Jiangxi,
A set of four, each containing about 5 ml of water. Now the tea set for making oolong tea is still inseparable from the "teahouse Four Treasures of the Study", but it has changed and become more practical and convenient. The commonly used "teahouse Four Treasures of the Study" has a small electric stove, a steel kettle (some electric stoves and kettles are also called "instant soaking"), a steel tea tray (or plastic tea tray) and a "white porcelain bowl" (bell-shaped, 5.5 cm high, 8.2 cm in diameter and 4.5 cm in bottom diameter; This bowl is convenient for putting tea leaves, smelling aroma, boiling water and pouring tea dregs) and a small teacup, so it has the conditions for making oolong tea.
Third, the skills of soaking wine
Oolong tea has unique skills in soaking and drinking, and it also has some fun in the process of soaking and drinking. Its brewing technology has eight processes.
The first is boiling water, and the water temperature is "one boiled water" (that is, just boiled water). After the water boils, rinse the cover bowl (or teapot) and the teacup once, which is sanitary and warm, and then put the oolong tea into the cover bowl (or teapot). The amount of tea used to cover the bowl is 5- 10g, depending on the size of the teapot. Small teapot accounts for about four or five points of teapot capacity, medium teapot accounts for about three or four points, and large teapot accounts for about two or three points. These actions include Landau procedures, namely "the first boiling of the mountain spring", "the white crane bathing" and "the oolong entering the palace".
Then lift the kettle and rush into the bowl or teapot from a height to make the tea in the bowl (kettle) rotate and make the tea fragrant; Immediately after the boiling water is filled, cover the bowl (pot), wait a moment, and gently scrape off the white foam floating on it with the bowl (pot) cover to make the tea fresh and clean. This is the fourth and fifth procedure, which is called "hanging pot high flush" and "spring breeze stroke"
After soaking for a minute or two (the soaking time should be appropriate, too short, and the color, fragrance and taste can't come out; Too long, it will produce bitterness. Cover the bowl tightly with your thumb and middle finger, press the lid with your forefinger, and pour the tea into the small cups in parallel. Pour the tea low, so as not to lose its fragrance and taste. Pour it to the thickest part at the bottom of the last bowl and drop it evenly into each teacup. In this way, a uniform color tone and consistent fragrance are achieved, which also contains the deep affection of the owner. These are the sixth and seventh procedures, which are called "Guan Gong patrolling the city" and "Han Xin ordering troops".
Once the tea leaves are poured into the cup, they should be carefully sucked dry by the hot air so as not to affect the color and fragrance. When drinking, smell it first, then taste it, and smell it while drinking. Although the amount of drinking is not much, it can leave a fragrance on the teeth and cheeks, and the bottom of the throat is sweet, refreshing and refreshing. This is the eighth procedure, called "Taste the Rain".
When making tea for the second time, you should still boil the cup with boiling water and soak for two or three minutes before pouring tea. Next, the third time and the fourth time ... the process of making tea is basically the same, but the time of making tea is longer than one, but it depends on the quality of tea. Good oolong tea, such as Tieguanyin, still smells after being brewed for seven or eight times.
Although the pace of people's life has been accelerated, if we can follow the tradition and have a good drink after work and in our leisure time, we can not only adapt to the fast-paced modern life, but also cultivate our sentiments, increase unlimited life fun and gain wonderful artistic enjoyment.
