Women drink black tea efficacy and role of harm and ten taboos black tea is not suitable for who to drink

A total of four kinds of catechins are the main components of black tea, also known as tannins.

The four catechins are ECG (epigallocatechin gallate), EC (epicatechin), EGCG (epigallocatechin gallate) and EGC (epigallocatechin).

In addition to black tea, almost all teas, such as Japanese tea and Chinese tea, contain catechin black tea after oxidation and fermentation. so there are more black tea polyphenols that bring red brown-- theaflavins, which are the three major elements of black tea-- taste, fragrance and brown, which are intertwined by catechin black tea polyphenols.

Europe, which once regarded tea as a mysterious oriental medicine, believes that it has rich effects, but it is somewhat as impractical as legend, but in recent years, institutions such as the Institute of Black Tea and Life, which specialize in black tea, have explored the effects of various ingredients in jar tea on the human body, and confirmed many arguments from a scientific point of view.

In an easy-to-understand way, the Institute of Black Tea and Life will highlight some of the most eye-catching items:

Prevention of influenza

No matter which type of influenza virus is mutated, the catechins and lycopene of jar tea can attach to the front end of the virus (spike), inhibit the activity of the virus and help the body eliminate the virus.

Recent studies have also found that jar tea can inhibit the reproduction of periodontal pathogenic bacteria. Periodontal pathogens are not only famous for their role in promoting the spread of viruses, but also cause halitosis by breaking down proteins in the mouth by an enzyme, both of which are known to originate from the same enzyme.

Black tea can block proteolytic enzymes, so it helps to prevent influenza.

Prevention of skin aging caused by ultraviolet rays (Institute of Black Tea and Life)

On May 30, 2015, the 15th Anti-Aging Medical Association, with the theme of "Photoinhibition effect of Black Tea extract, talked about theaflavins in black tea polyphenols, which can improve skin roughness caused by ultraviolet glands.

Help to improve osteoporosis

According to the Asahi Shimbun on Feb. 24, 2015, research institutions such as Osaka University have found that polyphenol TF3, which is rich in tea, helps improve osteoporosis, which makes bones fragile.

Intestinal function

Tannins and caffeine can contract the gastric mucosa, promote gastrointestinal secretion and help digestion. Better digestion can trigger appetite and help clean up the gastrointestinal environment and promote health.

Prevention of exercise hardening and hypertension

The intake of too much cholesterol will attach to the sports clothing, which will make the blood vessels hard, lose elasticity gradually, and cause the exercise clothing to harden. EGCG, one of the main ingredients of black tea, does not know that it can lower the concentration of cholesterol in the blood and can also send cholesterol back to the liver.

There is a kind of hypertension with many genetic factors, which is still unknown, which is called essential hypertension. The catechins in black tea are famous for their powerful blood pressure lowering function, and people with daily low blood pressure or normal blood pressure will not fall below the normal value.

Prevention of food poisoning

All kinds of bacteria, such as Escherichia coli, can cause food poisoning. EGCG, polyphenolic theaflavins and lycopene in black tea all have strong bactericidal ability, can prevent reproduction and eliminate bacteria at the same time, and are particularly effective in defending coliform bacteria, so they are of great help in preventing food poisoning.

Prevent obesity

You can drink a cup of tea before exercise, use catechins to promote fat energy metabolism, inhibit the body's decomposition and absorption of neutral fat, and effectively prevent obesity. Getting into the habit of taking exercise after drinking a jar of tea can be said to be a great health management.

Restrain the rise of blood glucose and prevent diabetes

If the amount of glucose in the blood increases abnormally, it will evolve into diabetes and the insulin ability responsible for regulating glucose metabolism in the body will become worse, and the blood will be filled with glucose. Finally, when the buttocks cannot be treated, the urine will be mixed with glucose. In this way, it is easy to cause liver dysfunction, suspected hip failure.

The catechins in black tea can inhibit the increase in blood sugar levels, so you can also drink black tea in daily life after suffering from diabetes, thus slowing down the increase in blood sugar levels.

Prevention of cancer

EGCG in black tea can activate lymphocytes in the body, inhibit the division of cancer cells, and the effect is proportional to the concentration of catechins. At present, Japan, the United States and other countries are studying the efficacy of the Taoist part.

Prevention of tooth decay

Will dissolve the teeth to produce hollow carious bacteria, after breaking down the food attached to the teeth, it will produce dextran and form tartar. After the teeth are covered with hard tartar, dental caries will hide and move in it.

Catechin has the effect of killing carious bacteria, and black tea contains fluorine, which helps to strengthen the surface of teeth and resist the acid produced by dental caries bacteria.
