Summer Health Guide: drink a cup of tea to control sugar"

China"s tea culture, has a long history, the regimen is recorded in history. Today we are going to review the in the "tea culture" and drop three chapter.
"Tea for all disease medicine", is highly of multifunctional health role of the Tang Dynasty medical scientist Chen cangqi of tea. Traditional Chinese medicine believes that tea bitter, sweet, cold, into the heart, liver, spleen, lung. Bitter to diarrhea, dampness, Qi; Gansu can help ease; cold heat, purging fire, detoxification. Li Shizhen in the "Compendium of Materia Medica" in the said: "the tea picking frivolous, when Mao sin is the beginning of adorable, gas spring. Although the taste is bitter and the gas is thin, is the Yin of Yang, can rise and fall." These characteristics that tea has to attack to fill, but also can play more fully into the five internal organs function.
Tea in the tea polyphenols, tea pigment, tea polysaccharide, tea saponin, GABA, theanine, caffeine, vitamin C and other components can inhibit lipid peroxidation, anticoagulant, fibrinolysis, platelet aggregation, lowering blood pressure, reducing blood lipid, prevention and treatment of atherosclerosis and cardiac protection. Can regulate the blood in a variety of indicators to improve the cardiovascular system, which will help the prevention and treatment of cardiovascular and cerebrovascular diseases.
How to drink weak tea for lowering blood pressure
Tea catechin carotenoid compounds and theaflavins, the more obvious antihypertensive effect, and can significantly inhibit angiotensin converting enzyme activity. Tea polyphenols mainly through the complex enzyme metal zinc ion, which can control the angiotensin converting enzyme activity, so that the role of the activation process of the blood pressure is blocked, to achieve the purpose of reducing blood pressure. For isolated rat hind limb blood vessel, tea polyphenols can also increase the amount of perfusion, with the role of vascular dilation. The Russian medical experts through clinical trials proved that with high concentrations of tea catechin can lower blood pressure, and drink more green tea predisposed to stroke and vascular blockage is useful, because it can maintain elasticity of blood vessels, elimination of vascular spasm, can prevent the function of the rupture of blood vessels.
In addition, tea caffeine and catechin class can make a relaxation of vascular wall, the effective diameter increases vascular, through the expansion of blood vessels and decreased blood pressure. Japan has adopted a new processing technology, fresh tea leaves under nitrogen treatment for 6 hours, so that the formation of a large number of tea oxygen acid, according to clinical trials, to reduce blood pressure has a significant effect. Aromatic glycosides in tea (Lu Ding) also has to maintain normal capillary resistance and enhance the toughness effect of vascular wall.
Tea and tea to reduce blood lipid
Hyperlipidemia strictly defined for dyslipidemia or abnormal is refers to the serum lipids in human body is beyond the normal range, serum total cholesterol and triglycerides, serum high density lipoprotein cholesterol level is abnormally low, attachment in vascular wall caused by arteriosclerosis and heart bring burden, thereby reducing the heart function. The lipid-lowering effects of tea, Chinese ancient literature has concentrated solution of oil "(" old "," Heng Yan) to greasy "(" Dongpo sungji "). "To grease" ("herbal supplements") and other records, modern clinical, tea is It is often seen. fat.
All kinds of tea have a certain degree of lipid-lowering effect, especially to oolong tea, green tea and Pu"er tea is most effective, high fat acidosis in patients drinking tea and oolong tea to varying degrees reduce cholesterol, triglyceride, beta lipoprotein and total lipid content, Tuocha treating hyperlipidemia total efficiency was 92% to 86% that Tuocha has significant lipid-lowering effect.
So, why tea can lower blood lipids and cholesterol, which is mainly attributed to the rich tea polyphenols, tea polysaccharides, tea pigments and vitamin C, etc.. One is the tea polyphenol monomer or polymer (tea pigment such as theaflavins) has significantly reduced blood lipids, tea polyphenols reduced lipid mechanism is mainly through the following ways: inhibition of intestinal cholesterol uptake and absorption; inhibit cholesterol synthesis, reduce lipoprotein lipase activity; inhibition of lipoprotein synthesis, accelerate the decomposition of lipid, promote the conversion of cholesterol to bile acid and cholesterol content is reduced. Two tea polyphenols can dissolve fat: fat metabolism plays an important role, not only significantly inhibit the rise of plasma and liver cholesterol, but also to promote the excretion of lipid compounds from feces. In addition to tea polyphenols, tea polysaccharide also has a significant effect on high blood lipids. Tea polysaccharide can increase the content of high density lipoprotein cholesterol, but also can be combined with lipoprotein lipase to promote arterial wall lipoprotein lipase to enter the blood.
Drink more green tea to lower blood sugar
In recent years, tea to help lower blood sugar in many patients with diabetes have become a friend of fashion, and often see some patients with each other to copy tea and sugar sugar, the experience of common exchange of tea. Tea can reduce blood sugar, has been confirmed by a large number of domestic and international research, but in the end what ingredients of tea can reduce blood sugar, and it is how to play the role of it?
Tea polysaccharide is the main component of tea. Tea polysaccharide is the abbreviation of tea polysaccharide, which is composed of sugar, pectin, protein, etc., including Arabia sugar, xylose, glucose, galactose, galactose and other water-soluble polysaccharide. Tea polysaccharide is the main function of lowering blood sugar, lowering blood fat, so as to achieve the role of prevention and control of diabetes.
Green Tea, Oolong Tea, Black Tea, black tea, white tea in the tea polysaccharide have hypoglycemic effect significantly. The hypoglycemic effect of tea polysaccharide is related to the protection of the secretory activity of the pancreatic islet cells, so that the large amount of glycogen in the liver is increased. The effect of tea polysaccharides on glucose metabolism is similar to that of insulin.
Tea polysaccharide through improving the antioxidant power of the body
