自古以来,我国人民对饮茶与人体健康的关系有着极深的研究。古今中外的医学家都肯定铁观音茶有无与伦比的保健功能。

铁观音茶叶在当今三大饮料中,保健功能首屈一指,是咖啡、可可无法比拟的,更是众多令人眼花缭乱的现代人工合成饮料所不能相提并论的。

铁观音茶叶含有营养和药效成分,已被世界医学界公认为“原子时代的理想饮料”和“当代最佳保健饮料”。

茶的保健功效

科学家认为,喝大量茶是人长寿的秘诀之一,茶的保健功效也被现代科学所证实。

安溪铁观音茶叶中维生素C含量高,能促使脂肪氧化,排出胆固醇,参与人体内物质的氧化还原反应,促进解毒作用。

茶中的维生素和微量元素具有保持血管弹性、防治高血压和动脉硬化的作用。

另外,茶还能兴奋血管中枢,增强心、肾功能,促进血液循环,增强肾小球过滤率,使尿液增多。

茶叶中还含有大量咖啡碱,有很强的利尿作用,不仅可预防肾结石的形成,降低胆固醇,而且对蛋白质类食物有良好的消化作用。

软化血管

茶能增强血管弹性,促进血液循环,使冠状动脉扩张,具有强心作用,对预防冠心病、高血压、中风等疾病有一定作用。

现代科学研究证实,饮用绿茶能显著降低血清总胆固醇含量,

对血清中甘油三酯的降低也有显著作用,揭示了绿茶可以缓解和预防心血管病及动脉粥样硬化症的功效。

提神醒脑

茶能兴奋中枢神经,有利于提神解乏,消除疲劳,增强记忆。


茶叶中咖啡碱最主要的作用是兴奋大脑皮层、中枢神经以及延脑呼吸中枢和血管运动中枢。

咖啡碱、茶碱可直接增强心肌收缩力,加快心率,扩张冠状动脉,收缩脑血管,所以,饮茶能振奋精神,活跃思维,消除疲劳。

延缓衰老

许多研究证实茶中所含的鞣酸是一种强有力的抗氧化物,它中和氧化的能力是维生素E的18 倍,在人体内可发挥抗衰老的作用。

根据细胞染色体与衰老关系的学说,衰老的主要原因是细胞染色体的断裂,


而茶中鞣酸,可使染色体不致因氧化而发生断裂,因而可延缓衰老。




5


降血压作用

高血压是一种人类常见病,是以动脉血压持续增高为主的临床症候群。

目前已经证明茶叶中的儿茶素类化合物(特别是ECG和EGCG)和茶黄素,对血管紧张素I转化酶活性有明显的抑制作用。

同时多喝绿茶对易致中风和血管淤塞的人是有益的,因为它可以使血管保持弹性,消除脉管痉挛,

此外,茶叶中的咖啡碱和儿茶素类能使血管壁松弛,增加血管的有效直径,通过血管舒张而使血压下降。

降低辐射的危害

日本在广岛原子弹爆炸后,将蒙难者迁移到茶区居住并饮用大量优质绿茶,

不仅仍然存活,而且体质良好,这一调查发现,茶是一种有希望的辐射解毒剂。

有人用绿茶、红茶和茶叶中提取的多酚类化合物进行实验,结果证明茶叶可以吸收的时间比同位素到达骨髓的时间为短。

进一步的实验还发现,茶叶中多酚类化合物具有吸收放射性锶并阻止它扩散的作用。

饮用足够数量的浓绿茶,可使生物体内积累的锶—90数量显著低于允许水平。它对紫外线有强烈的吸收作用,是一种防晒物质。

Since ancient times, the people of our country have conducted in-depth research on the relationship between tea drinking and human health. Medical scientists at home and abroad have affirmed that tea has unparalleled health functions.

Among the three major beverages today, tea has the most health-care function. It is unmatched by coffee and cocoa, and it is unmatched by many dazzling modern synthetic beverages.

Tea contains nutrients and medicinal ingredients, and has been recognized by the world medical community as the "ideal drink in the atomic age" and the "best contemporary health drink".

Health benefits of tea

Scientists believe that drinking a lot of tea is one of the secrets of longevity, and the health benefits of tea have also been confirmed by modern science.

The high content of vitamin C in tea can promote fat oxidation, excrete cholesterol, participate in the redox reaction of substances in the human body, and promote detoxification.

The vitamins and trace elements in tea can maintain the elasticity of blood vessels, prevent high blood pressure and arteriosclerosis.

In addition, tea can also excite the vascular center, enhance heart and kidney function, promote blood circulation, enhance glomerular filtration rate, and increase urine.

Tea also contains a large amount of caffeine, which has a strong diuretic effect. It can not only prevent the formation of kidney stones and lower cholesterol, but also has a good digestion effect on protein foods.

Soften blood vessels

Tea can enhance the elasticity of blood vessels, promote blood circulation, expand the coronary arteries, have a heart strengthening effect, and have a certain effect on preventing coronary heart disease, hypertension, stroke and other diseases.

Modern scientific research has confirmed that drinking green tea can significantly reduce serum total cholesterol content.

It also has a significant effect on the reduction of serum triglycerides, revealing that green tea can relieve and prevent cardiovascular disease and atherosclerosis.


3


Refreshing

Tea can excite the central nervous system, is good for refreshing and relieving fatigue, eliminating fatigue and enhancing memory.


The main function of caffeine in tea is to excite the cerebral cortex, central nervous system and the respiratory center and vascular movement center of the brain.

Caffeine and theophylline can directly enhance myocardial contractility, speed up heart rate, expand coronary arteries, and contract cerebral blood vessels. Therefore, drinking tea can invigorate the spirit, activate thinking, and relieve fatigue.



4


anti aging

Many studies have confirmed that the tannic acid contained in tea is a powerful antioxidant, its ability to neutralize oxidation is 18 times that of vitamin E, and it can play an anti-aging effect in the human body.

According to the theory of the relationship between cell chromosomes and aging, the main cause of aging is the breakage of cell chromosomes.


The tannic acid in tea prevents chromosomes from being broken due to oxidation, thus delaying aging.




5


Blood pressure lowering effect

Hypertension is a common human disease, which is a clinical symptom dominated by a continuous increase in arterial blood pressure.

It has been proved that the catechin compounds (especially ECG and EGCG) and theaflavins in tea have a significant inhibitory effect on the activity of angiotensin I converting enzyme.

At the same time, drinking more green tea is beneficial to people who are prone to stroke and vascular congestion, because it can keep blood vessels elastic and eliminate vasospasm.

In addition, the caffeine and catechins in tea can relax blood vessel walls, increase the effective diameter of blood vessels, and reduce blood pressure through vasodilation.

Reduce radiation hazards

After the atomic bombing of Hiroshima, Japan moved the victims to live in tea districts and drank large amounts of high-quality green tea.

Not only is still alive, but also in good physical condition. This investigation found that tea is a promising antidote to radiation.

Some people conducted experiments with polyphenols extracted from green tea, black tea and tea, and the results proved that the time that tea can absorb is shorter than the time it takes for isotopes to reach the bone marrow.

Further experiments also found that the polyphenolic compounds in tea have the effect of absorbing radioactive strontium and preventing its diffusion.

Drinking a sufficient amount of strong green tea can make the amount of strontium-90 accumulated in the organism significantly lower than the allowable level. It has a strong absorbing effect on ultraviolet rays and is a sunscreen substance.
