Obesity is a series of disorders of eating regulation and energy metabolism caused by specific biochemical factors. A series of diseases caused by obesity has become the main killer of human health. The tea polyphenols and their oxidation products in dark tea can dissolve fat and promote the excretion of lipid substances, thus reducing the content of total cholesterol, free cholesterol, low-density lipoprotein cholesterol, and triglyceride in the blood, thus reducing the cholesterol deposition on the arterial wall and reducing the incidence of arteriosis. Can also activate protein kinase, accelerate the decomposition of fat, reduce the body fat content. In human trials, the scientists found that people who drank tea consumed an average of 67eal more energy per day and had a 12 percent higher rate of fat oxidation than those who drank plain water. This proves that dark tea does reduce fat and loss weight.
2. Enhance gastrointestinal function, improve the body immunity
The effective ingredients of dark tea can not only inhibit the growth of harmful microorganisms in the human intestines and stomach but also promote the growth and reproduction of beneficial bacteria (such as lactic acid bacteria), which has a good function of regulating gastrointestinal function.

The study also found that the catechin compounds in black tea and tea saponin on oral bacteria, spiral bacteria, escherichia coli, typhoid and paratyphoid coli, staphylococcus aureus, and other bacterial pathogens kill and inhibition of plant growth, thus has significant stagflation, check leakage, eliminate constipation, white-collar workers, for the work of often sit plays an important role, and folk check the medicine of the drain, Theanine in dark tea has a good function of enhancing human immunity.
3. Anti-aging, regulating brain nerve effect
The natural aging process of the human body has a common occurrence with degenerative diseases such as tumors and cardiovascular diseases, that is, cells are damaged by oxidative radicals. More than 95% of free radicals in the human body are oxygen free radicals, which are the basis of damaging biological macromolecules and participating in the occurrence and development of various diseases as well as aging. Under normal circumstances, the human body is constantly produced free radicals, also constantly cleared, in equilibrium. But in some cases, free radical production and clearance are out of balance, resulting in protein denaturation, reduced enzyme activity, and other hazards, resulting in various diseases and accelerated aging. Catechins and complex flavonoids in dark tea have very active hydroxyl hydrogen, which can provide a large number of hydrogen protons to react with free radicals and remove excess free radicals, thus protecting human health and longevity.
4.Reduce blood pressure and blood sugar
The theanine in black tea can have the effect of inhibiting blood pressure, and alkaloids and flavonoids substances have made relaxation of blood vessels increase the effective diameter of blood vessels, through making vasodilatation and blood pressure drop, diabetes is one of the elderly health killers in the modern, and, with the improvement of people’s living standard and the aging of the population, the incidence of diabetes increased gradually.
