Anti-atherosclerosis effect of tieguanyin tea:
Tea polyphenols play an important role in human fat metabolism. The body's cholesterol, triglyceride and other high content, blood vessel wall deposition, vascular smooth muscle cells proliferate to form atherosclerotic plaque and other cardiovascular diseases. Tea polyphenols, especially catechins ecg and egc in tea polyphenols and its oxidation product, theaflavins, help to inhibit this plaque-proliferation, reduce the formation of fibrinogen with enhanced blood coagulation, and coagulate cleared to inhibit atherosclerosis.
On may 31, 1999, at the fourth oolong tea and health symposium held in tokyo, japan, vice president chen ling of the fujian academy of traditional chinese medicine reported that they had 25 obese people with hyperlipidemia as clinical observation targets. To explore the effect of drinking oolong tea tieguanyin tea 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 tea can inhibit the oxidation of low-density lipoprotein in the blood. Dr. Yukio, formerly from the mitsui institute of agriculture and forestry in japan, has confirmed in many years that tea polyphenols not only lowers blood cholesterol, but also significantly improves the ratio of high-density lipoprotein to low-density lipoprotein in the blood. Caffeine can relax blood vessels, speed up breathing, lower blood lipids, and has a certain effect on prevention and treatment of cardiovascular and cerebrovascular diseases such as coronary heart disease, hypertension and arteriosclerosis.
According to a survey conducted by the fujian medical university coronary heart disease prevention and control research group in 1974 in anxi tea township, fujian province, the incidence of not drinking tieguanyin tea was 3.1%; the occasional drink was 2.3%; the perennial drink (more than 3 years) ) is 1.4%. It can be seen that people who often drink tieguanyin tea have a lower incidence of coronary heart disease than those who do not drink tieguanyin tea.
