Original title: The efficacy and role of black tea
Hualong.com, April 27th, 13th, it can now be said that tea has become the best health drink for our human beings. No matter what kind of tea it is, it has a very good effect on the health care of our human body. It is possible that we are more familiar with black tea, green tea or oolong tea. It can be said that there are fewer people who drink dark tea. If there are people who drink dark tea, they should basically drink Pu-erh tea. Some people will ask why Pu-erh tea is black tea? In fact, this may be your unfamiliar, Pu’er tea is a serious black tea. So what we want to know today is what are the functions and functions of black tea.
1. Eliminate cellulite and lose weight: Obesity is a series of diseases caused by specific biochemical factors that cause disturbances in eating regulation and energy metabolism. A series of diseases caused by obesity have become the main killers endangering human health.
Tea polyphenols and their oxidation products in dark tea can dissolve fat and promote the excretion of lipid substances, so they can reduce the content of total cholesterol, free cholesterol, low-density lipoprotein cholesterol and triglyceride in the blood, thereby reducing arterial Cholesterol deposition on the vessel wall, reducing the incidence of arterialization. Moreover, dark tea is rich in vitamin B1, which plays an important role in the process of fat oxidation and decomposition to release heat, which can promote fat burning; the rich tannins in dark tea can clean up the stomach and promote the timely discharge of metabolic wastes from the body. It can also activate protein kinases, accelerate the decomposition of fat, and reduce the fat content in the body. Scientists have found through human experiments that compared with people who drink ordinary water, the daily energy consumption of tea drinkers is 67eal higher on average, and the fat oxidation rate is higher than 12%. This proves that black tea does have a lipid-lowering and weight-loss effect. Black tea is known as “slimming tea” and “beauty tea” overseas.
2. Lowering the third high: The unique theanine in black tea can inhibit the rise of blood pressure by activating dopaminergic neurons. In addition, caffeine and catechins in black tea can relax the blood vessel wall, increase the effective diameter of blood vessels, and reduce blood pressure through vasodilation. Diabetes is one of the health killers of modern middle-aged and elderly people, and with the improvement of people’s living standards and the intensification of population aging, the incidence of diabetes is gradually increasing. So far, diabetes is still an incurable disease, which is mainly controlled by drugs and dietary adjustments. Studies have shown that black tea is the type of tea that contains the most tea polysaccharides. Tea polysaccharides can help people lower blood sugar levels in the body. The oxidative substances and tea polyphenols in it can dissolve fat, effectively promote fat excretion and reduce blood levels. This is because the action of glycosidase, protease and hydrolase in fermented tea forms relatively short sugar chains and peptide chains, which are more easily absorbed and have stronger biological activity. The efficacy is much higher than other teas.
3. Enhance gastrointestinal function, improve immunity, and aid digestion: while inhibiting the growth of harmful microorganisms in the human gastrointestinal tract, the active ingredients of black tea can also promote the growth and reproduction of beneficial bacteria (such as lactic acid bacteria), which has a good effect on adjusting gastrointestinal function. , its alkaloids can promote the secretion of gastric juice, and flavanols can significantly enhance gastrointestinal motility. The study also found that the catechin compounds and tea saponins in dark tea can kill and inhibit the growth of oral bacteria, Helicobacter, Escherichia coli, Typhoid and Paratyphoid Bacillus, Staphylococcus and other pathogens, so they have significant effects. It has the effect of eliminating stagnation, stopping diarrhea, and eliminating constipation. It plays an important role in the white-collar workers who often sit and work. It is also a good medicine for people to stop diarrhea. Moreover, caffeine, vitamins, amino acids, phospholipids, etc. in black tea are helpful for human digestion and can help regulate fat metabolism. The stimulating effect of caffeine can increase the secretion of gastric juice, thereby increasing appetite and helping digestion. Theanine in black tea has a good function of enhancing human immunity.
