铁观音的功效

一、关于铁观音

铁观音，发源于福建安溪，至今有近300年的历史，属于乌龙茶类，是中国十大名茶之一乌龙茶类的代表。铁观音独具“观音韵”，“七泡余香溪月露，满心喜乐岭云涛”，除具有一般茶叶的保健功能外，还具有抗衰老、抗癌症、抗动脉硬化、防治糖尿病、减肥健美、防治龋齿、清热降火，敌烟醒酒等功效。曾以“十大名茶之首”亮相2010年上海世博会。

二、喝茶益处多，喝铁观音更是有八大好处和功效

功效1、抵抗衰老

科学研究表明，人的衰老与体内不饱和脂肪酸的过度氧化作用有关，而不饱和脂肪酸的过度氧化是与自由基的作用有关。铁观音中的多酚类化合物能防止过度氧化;嘌呤生物碱，可间接起到清除自由基的作用，从而达到延缓衰老的目的。

功效2、预防癌症

如今饮茶可以防癌抗癌已被世人所公认，而在茶叶中防癌抗癌效果最好的是铁观音。早在1983年，日本冈山大学奥田拓男教授就曾对数十种植物多酚类化合物进行抗癌变作用筛选，结果证明：儿茶素(EGCG)具有很强的抗癌变活性。其他科学家在证实铁观音抗变异的研究中，认为铁观音茶多酚是这一作用的主要活性成分;在化学物质致癌的研究中，肯定了铁观音茶多酚的防止癌变作用。此外，铁观音中的维生素C和维生素E能阻断致癌物——亚硝胺的合成，对防治癌症有较大的作用。

功效3、降压防糖尿病

铁观音茶叶中的咖啡碱能舒张血管，加快呼吸，降低血脂，对防治冠心病、高血压、动脉硬化等心脑血管疾病有一定的作用。糖尿病得病的主要原因是体内缺乏多酚类物质，如维生素B1、泛酸、水杨酸甲酯等成分，使糖代谢发生障碍，体内血糖量剧增，代谢作用减弱。而经常饮茶可以及时补充人体中的多种成分，从而能防止糖尿病的发生。

功效4、减肥美容

引起肥胖的主要原因是人体的胆固醇和脂肪过高，堆积在人体中使人发胖，而茶叶中的维生素等成分可以加快人体胆固醇的排出，同时可以抑制人体中负责分解脂类的酶的活性，使得脂类物质难以分解，从而没有办法被肠道吸收，达到减肥美容的效果。

功效5、提神益思

铁观音可提神益思，其功能主要在于茶叶中的咖啡碱。咖啡碱具有兴奋中枢神经、增进思维、提高效率的功能。因此，饮茶后能破睡、提神、去烦、解除疲倦、清醒头脑、增进思维，能显著地提高口头答辩能力及数学思维的反应。同时，由于铁观音中含有多酚类等化合物，抵消了纯咖啡碱对人体产生的不良影响。这也是饮茶历史源远流长、长盛不衰、不断发展的重要原因之一。

功效6、清热杀菌

茶是一种上好的天然饮料，喝茶可以止渴生津。因为茶叶中含有的多酚类等成分可以与人体口腔中的唾液发生化学反应，使人体的口腔感到一定的舒适感。茶叶中含有的咖啡碱可以加快能量从人体中排出，在夏天饮用时可以让人有凉爽的感觉。茶叶中的茶多酚在与由蛋白质构成的细菌相遇时可以将蛋白质凝固从而使细菌因凝固而死亡，达到了杀死细菌的效果。

功效7、醒酒敌烟

酒的主要成分是乙醇，乙醇与茶叶中的茶多酚相遇后，会产生一定的化学反应，会分解掉，达到解酒效果。同时我们知道香烟中含有危害的主要是尼古丁成分，茶叶中的部分化合物会与尼古丁发生反应，使其沉淀，然后排出体外，从而喝铁观音可以达到敌烟醒酒的功效。

功效8、防龋齿除异味

安溪铁观音茶叶中含有大量的氟，众所周知氟是牙膏中必不可少的成分，有利于牙齿的保健。因为氟极易与牙齿中的钙质相结合，在牙齿表面形成一层氟磷酸钙，起到防酸抗龋的作用。同时经常用铁观音漱口还可以达到去除口腔异味的作用。

1. About Tieguanyin

Tieguanyin originated in Anxi, Fujian, and has a history of nearly 300 years. It belongs to the category of oolong tea and is the representative of one of the top ten famous teas in China. Tieguanyin has a unique "Guanyin rhyme", "seven bubbles of fragrance and moon dew, full of joy in the mountains and clouds", in addition to the health care functions of ordinary tea, it also has anti-aging, anti-cancer, anti-arteriosclerosis, prevention and treatment of diabetes, and weight loss. Bodybuilding, prevention and treatment of dental caries, clearing heat and reducing fire, anti-smoking and sobering up. It appeared in the 2010 Shanghai World Expo as the "Top Ten Famous Teas".

2. Drinking tea has many benefits, and drinking Tieguanyin has eight benefits and effects

Efficacy 1. Anti-aging

Scientific research shows that human aging is related to the excessive oxidation of unsaturated fatty acids in the body, and the excessive oxidation of unsaturated fatty acids is related to the effect of free radicals. The polyphenolic compounds in Tieguanyin can prevent excessive oxidation; purine alkaloids can indirectly scavenge free radicals, thereby achieving the purpose of delaying aging.

Efficacy 2, prevent cancer

Nowadays, drinking tea can prevent and fight cancer has been recognized by the world, and the best anti-cancer and anti-cancer effect in tea is Tieguanyin. As early as 1983, Professor Okuda Takuo of Okayama University in Japan screened dozens of plant polyphenolic compounds for their anticancer effects, and the results proved that catechin (EGCG) has strong anticancer activity. Other scientists believe that Tieguanyin tea polyphenols are the main active ingredients in the research that confirms Tieguanyin's anti-mutation; In addition, vitamin C and vitamin E in Tieguanyin can block the synthesis of carcinogens - nitrosamines, and have a greater effect on the prevention and treatment of cancer.

Efficacy 3, blood pressure and diabetes prevention

The caffeine in Tieguanyin tea can dilate blood vessels, speed up breathing, reduce blood lipids, and have a certain effect on the prevention and treatment of coronary heart disease, hypertension, arteriosclerosis and other cardiovascular and cerebrovascular diseases. The main cause of diabetes is the lack of polyphenols in the body, such as vitamin B1, pantothenic acid, methyl salicylate and other components, which impair glucose metabolism, increase blood sugar in the body, and weaken the metabolism. Drinking tea regularly can replenish various components in the human body in time, thereby preventing the occurrence of diabetes.

Efficacy 4. Weight loss and beauty

The main reason for obesity is that the cholesterol and fat in the human body are too high, which accumulates in the human body and makes people fat. The vitamins and other ingredients in tea can speed up the excretion of cholesterol in the human body, and at the same time can inhibit the activity of enzymes responsible for decomposing lipids in the human body. It makes it difficult for lipid substances to be decomposed, so that there is no way to be absorbed by the intestinal tract to achieve the effect of weight loss and beauty.

Efficacy 5. Refreshing thoughts

Tieguanyin can refresh the mind, and its function is mainly due to the caffeine in tea. Caffeine has the functions of exciting the central nervous system, improving thinking and improving efficiency. Therefore, after drinking tea, it can break sleep, refresh the mind, get rid of troubles, relieve fatigue, clear the mind, improve thinking, and can significantly improve the oral defense ability and the response of mathematical thinking. At the same time, because Tieguanyin contains compounds such as polyphenols, it offsets the adverse effects of pure caffeine on the human body. This is also one of the important reasons for the long history of tea drinking, enduring prosperity and continuous development.

Efficacy 6, heat and sterilization

Tea is a good natural drink, drinking tea can quench thirst and promote body fluid. Because the polyphenols and other components contained in tea can chemically react with the saliva in the human mouth, so that the human mouth feels a certain sense of comfort. The caffeine contained in tea can speed up the excretion of energy from the human body, which can make people feel cool when drinking in summer. Tea polyphenols in tea leaves can coagulate proteins when they meet with bacteria composed of proteins, so that bacteria die due to coagulation, and achieve the effect of killing bacteria.

Efficacy 7. Sober up and fight against tobacco

The main component of wine is ethanol. After the ethanol meets the tea polyphenols in the tea leaves, a certain chemical reaction will occur, and it will be decomposed to achieve the effect of hangover. At the same time, we know that nicotine is the main component of harm in cigarettes, and some compounds in tea will react with nicotine to precipitate, and then excreted from the body, so that drinking Tieguanyin can achieve the effect of sobering up against tobacco.

Efficacy 8. Anti-caries and deodorant

Tea contains a lot of fluorine. It is well known that fluorine is an essential ingredient in toothpaste, which is beneficial to the health of teeth. Because fluorine is easily combined with calcium in teeth, a layer of calcium fluorophosphate is formed on the surface of teeth, which plays the role of anti-acid and anti-caries. At the same time, gargling with Tieguanyin regularly can also achieve the effect of removing bad breath.
