铁观音的作用与功效;

一、铁观音的抗衰老作用

铁观音中的多酚类化合物——茶多酚具有很强的抗氧化性和生理活性，是人体自由基的清除剂。据有关部门研究证明1毫克茶多酚清除对人肌体有害的过量自由基的效能相当于9微克超氧化物歧化酶（SOD），大大高于其它同类物质。茶多酚有阻断脂质过氧化反应，清除活性酶的作用。据日本奥田拓勇试验结果，证实茶多酚的抗衰老效果要比维生素E强18倍。

二、铁观音的抗癌症作用

癌症是当今严重威胁人们健康的“不治之症”。因此，研究茶叶抗癌引起了人们的极大兴趣和关注。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

三、铁观音的抗动脉硬化硬化作用

茶多酚对人体脂肪代谢有着重要作用。人体的胆固醇、三酸甘油脂等含量高，血管内壁脂肪沉积，血管平滑肌细胞增生后形成动脉粥样化斑块等心血管疾病。茶多酚，尤其是茶多酚中的儿茶素ECG和EGC及其氧化产物茶黄素等，有助于使这种斑状增生受到抑制，使形成血凝黏度增强的纤维蛋白原降低，凝血变清，从而抑制动脉粥样硬化硬化。铁观音对抑制血中低密度脂蛋白的氧化及改善血中脂质代谢的作用。研究证明，铁观音中的茶多酚类化合物和维生素类可以抑制血中低密度脂蛋白的氧化。茶多酚类化合物不仅可以降低血液中的胆固醇，而且可以明显改善血液中高密度脂蛋白与低密度脂蛋白的比值。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、动脉硬化硬化等心脑血管疾病有一定的作用。

四、铁观音的防治糖尿尿糖作用

糖尿糖尿病是一种世界性疾病。全世界约有2亿人患糖尿糖尿病，中国有三千多万人患糖尿糖尿病。糖尿糖尿病是一种以糖代谢紊乱为主的全身慢性进行性疾病。典型的临床表现为“三多一少”，即多饮、多尿、多饮及消瘦，全身软弱无力。此病中医称“消渴症”，属下焦湿热范畴。得病的主要原因是体内缺乏多酚类物质，如维生素B1、泛酸、磷酸、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。经常饮茶可以及时补充人体中维生素B1、泛酸、磷酸、水杨酸甲酯和多酚类，能防止糖尿糖尿病的发生。对于中度和轻度糖尿糖尿病患者能使血糖尿尿糖糖尿糖尿病糖尿尿糖糖尿糖尿病很少，或完全正常；对于严重糖尿糖尿病患者，能使血糖、尿糖降低，各种主要症状减轻。

五、铁观音的减肥健美作用

肥胖症是一种伴随人们生活水平不断提高而出现的营养失调性病症，它是由于营养摄取过多或是体内贮存的能量利用不够而引起的。肥胖肥胖症不仅给人们日常生活中带来诸多不便，而且也是引发心血管疾病、糖尿糖尿病的一个原因。铁观音中含有大量的茶多酚物质，不仅可提高脂肪分解酶的作用，而且可促进组织的中性脂肪酶的代谢活动。因而饮用铁观音能改善肥胖者的体型，有效减少肥胖者的皮下脂肪和腰围，从而减轻其体重。

六、铁观音的防治龋齿作用

人们一般认为危害人的牙齿有两大疾病，一是龋齿，二是牙周炎。龋病俗称蛀牙，是牙科常见的多发病。龋齿发生的原因很多，其中有一个重要原因是：牙齿钙化较差，质地不够坚硬，容易受到破坏。饮茶可以保护牙齿，铁观音中含有较丰富的氟，而一般食物中含氟量很少。铁观音中的氟化物约有40%～80%溶解于开水，极易与牙齿中的钙质相结合，在牙齿表面形成一层氟化钙，起到防酸抗龋的作用。由此可见，饮用铁观音对未得龋齿的人有预防作用，对已得龋齿的人有治疗作用。

七、铁观音的杀菌止痢作用

主要是茶多酚化合物。由于茶多酚进入胃肠道后，能使肠道的紧张功能松弛，缓和肠道运动；同时，又能使肠道蛋白质凝固，因为细菌的本身是由蛋白质构成的，茶多酚与细菌蛋白质相遇后，细菌即行死亡，起到了保护肠胃黏膜的作用，所以有治疗肠炎的功效。

八、铁观音的清热降火作用

茶叶是防暑降温热好饮料。在盛夏三伏天，酷日当空，暑气逼人的时候，饮上一杯清凉铁观音或是一杯热铁观音，都会感到身心凉爽，生津解暑。这是因为茶汤中含有茶多酚类、糖类、氨基酸、果胶、维生素等与口腔中的唾液起了化学反应，滋润口腔，所以能起到生津止渴的作用。同时，由于铁观音中的咖啡碱作用，促使大量的能量从人体的皮肤毛孔里散出。据报道，喝一杯热茶，通过人体的皮肤毛孔出汗散发的热量，相当于这杯茶的50倍，故能使人感到凉爽解暑。

九、铁观音的提神益思作用

饮茶可以提神益思几乎人人皆知。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产、长盛不衰、不断发展的重要原因之一。

十、铁观音的醒酒敌烟作用

茶能醒酒敌烟，这也是众所周知的事实。而铁观音茶多酚能和乙醇（酒中主要成分）相互抵消，故饮茶能解酒。铁观音不仅能醒酒，而且能敌烟。由于铁观音中含有一种酚酸类物质，能使烟草中的尼古丁沉淀，排出体外。同时，铁观音中的咖啡碱能提高肝脏对药物的代谢能力，促进血液循环，把人体血液中的尼古丁从小便排泄出去，减轻和消除尼古丁带来的副作用。当然，这种作用不仅仅是咖啡碱的单一功效，而是与茶多酚、维生素C等多种成分协同配合的结果。

1. The anti-aging effect of Tieguanyin

The polyphenolic compounds in Tieguanyin - tea polyphenols have strong antioxidant and physiological activities, and are scavengers of free radicals in the human body. According to the research of relevant departments, the efficacy of 1 mg of tea polyphenols in scavenging excess free radicals harmful to human body is equivalent to 9 micrograms of superoxide dismutase (SOD), which is much higher than that of other similar substances. Tea polyphenols can block lipid peroxidation and remove active enzymes. According to the Japanese Okuda Takuyong test results, it is confirmed that the anti-aging effect of tea polyphenols is 18 times stronger than that of vitamin E.

2. The anti-cancer effect of Tieguanyin

Cancer is an "incurable disease" that seriously threatens people's health today. Therefore, the study of tea anti-cancer has aroused great interest and attention. Has strong anticancer activity. Other scientists believe that Tieguanyin tea polyphenols are the main active ingredients in the research to prove 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

3. Anti-arteriosclerosis effect of Tieguanyin

Tea polyphenols play an important role in human fat metabolism. The human body has high levels of cholesterol and triglycerides, and fat deposits on the inner wall of blood vessels, and vascular smooth muscle cells proliferate to form atherosclerotic plaques and other cardiovascular diseases. Tea polyphenols, especially the catechins ECG and EGC in tea polyphenols and their oxidation products theaflavins, etc., help to inhibit this kind of plaque hyperplasia, reduce the formation of fibrinogen with enhanced blood coagulation viscosity, and reduce blood coagulation. clear, thereby inhibiting atherosclerosis. The effect of Tieguanyin on inhibiting the oxidation of low-density lipoprotein in blood and improving lipid metabolism in blood. Studies have shown that tea polyphenols and vitamins in Tieguanyin can inhibit the oxidation of low-density lipoprotein in the blood. Tea polyphenols can not only reduce blood cholesterol, but also significantly improve the ratio of high-density lipoprotein to low-density lipoprotein in blood. Caffeine 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.

4. The effect of Tieguanyin on the prevention and treatment of diabetes and diabetes

Diabetes Diabetes is a worldwide disease. About 200 million people in the world suffer from diabetes, and more than 30 million people in China suffer from diabetes. Diabetes mellitus is a systemic chronic progressive disease dominated by disorders of glucose metabolism. The typical clinical manifestations are "three more and one less", namely polydipsia, polyuria, polydipsia and weight loss, and the whole body is weak. This disease is called "diabetes syndrome" in traditional Chinese medicine, and it belongs to the category of Jiao Damp Heat. The main reason for the disease is the lack of polyphenols in the body, such as vitamin B1, pantothenic acid, phosphoric acid, methyl salicylate and other components, which impede the glucose metabolism, increase the blood sugar level in the body, and weaken the metabolism. Drinking tea regularly can replenish vitamin B1, pantothenic acid, phosphoric acid, methyl salicylate and polyphenols in the human body in time, which can prevent the occurrence of diabetes and diabetes. For patients with moderate and mild diabetes, it can make blood sugar, urine, diabetes, diabetes, or completely normal; for patients with severe diabetes, it can reduce blood sugar and urine sugar, and relieve various main symptoms.

Five, the role of Tieguanyin for weight loss and bodybuilding

Obesity is a nutritional disorder that occurs with the continuous improvement of people's living standards. It is caused by excessive nutrient intake or insufficient utilization of stored energy in the body. Obesity Obesity not only brings a lot of inconvenience to people's daily life, but also is a cause of cardiovascular disease, diabetes and diabetes. Tieguanyin contains a lot of tea polyphenols, which can not only improve the function of lipolytic enzymes, but also promote the metabolic activity of neutral lipase in tissues. Therefore, drinking Tieguanyin can improve the body shape of obese people, effectively reduce the subcutaneous fat and waist circumference of obese people, thereby reducing their weight.

6. The role of Tieguanyin in the prevention and treatment of dental caries

It is generally believed that there are two major diseases that harm people's teeth, one is dental caries, and the other is periodontitis. Dental caries, commonly known as tooth decay, is a common and frequently-occurring disease in dentistry. There are many reasons for the occurrence of dental caries, one of which is an important reason: the calcification of the teeth is poor, the texture is not hard enough, and it is easy to be damaged. Drinking tea can protect your teeth. Tieguanyin is rich in fluorine, while ordinary food contains very little fluoride. About 40% to 80% of the fluoride in Tieguanyin is dissolved in boiling water, and it is easily combined with calcium in the teeth to form a layer of calcium fluoride on the surface of the teeth, which plays a role in preventing acid and caries. It can be seen that drinking Tieguanyin has a preventive effect on people who have not had caries, and has a therapeutic effect on those who have caries.

7. The bactericidal and antidiarrheal effect of Tieguanyin

Mainly tea polyphenol compounds. After entering the gastrointestinal tract, tea polyphenols can relax the nervous function of the intestinal tract and ease intestinal movement; at the same time, it can coagulate intestinal proteins, because bacteria themselves are composed of proteins, tea polyphenols and bacterial proteins After encountering, the bacteria die immediately and play a role in protecting the gastrointestinal mucosa, so it has the effect of treating enteritis.

8. The effect of Tieguanyin on clearing heat and reducing fire

Tea is a good drink to prevent heatstroke and cool down. In the dog days of midsummer, when the sun is in the sky and the heat is overwhelming, drinking a cup of cool Tieguanyin or a cup of hot Tieguanyin will make you feel cool physically and mentally and relieve the heat. This is because the tea soup contains tea polyphenols, sugars, amino acids, pectin, vitamins, etc., which chemically react with the saliva in the mouth to moisten the mouth, so it can play a role in promoting body fluid and quenching thirst. At the same time, due to the effect of caffeine in Tieguanyin, a large amount of energy is released from the skin pores of the human body. According to reports, drinking a cup of hot tea, the heat emitted by sweating through the pores of the human skin is equivalent to 50 times that of this cup of tea, so it can make people feel cool and relieve the heat.

Nine, the refreshing effect of Tieguanyin

Almost everyone knows that drinking tea can refresh the mind. 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, relieve irritability, relieve fatigue, clear the mind, improve thinking, and can significantly improve the ability of oral defense 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 why the history of tea drinking has aborted, prosperous and continuous development.

10. Tieguanyin's anti-smoking effect on sobering up

It is also a well-known fact that tea can sober up the enemy. Tieguanyin tea polyphenols and ethanol (the main ingredient in wine) can offset each other, so drinking tea can relieve hangover. Tieguanyin can not only sober up, but also fight against smoke. Because Tieguanyin contains a phenolic acid, the nicotine in tobacco can be precipitated and excreted. At the same time, the caffeine in Tieguanyin can improve the liver's ability to metabolize drugs, promote blood circulation, excrete nicotine in human blood from urine, and reduce and eliminate the side effects caused by nicotine. Of course, this effect is not only the single effect of caffeine, but the result of synergy with various ingredients such as tea polyphenols and vitamin C.
