喝茶不仅仅是享受，更多的是养生！Drinking tea is not only enjoyment, but also health preservation!
Since ancient times, the people of our country have had a deep 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 a health function second to none. 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".
01The 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 and treat hypertension 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 lot 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.
02 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, and also has a significant effect on the reduction of serum triglycerides, revealing that green tea can relieve and prevent cardiovascular disease and atherosclerosis.
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, 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.
04 Delays 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, and the tannic acid in tea prevents chromosomes from being broken due to oxidation, thus delaying senescence.
05Reduce blood pressure
Hypertension is a common human disease, which is a clinical syndrome dominated by a continuous increase in arterial blood pressure.
It has been proven 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.
06Reduce the harm of radiation
After the atomic bombing of Hiroshima, Japan moved the victims to the tea area and drank a lot of high-quality green tea. Not only were they still alive, but also in good health. This survey 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 showed that the time that tea can absorb is shorter than the time it takes for isotope 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.
