As one of the six major tea categories, dark tea has a long history and profound cultural heritage. However, many tea lovers often have little knowledge of the functions and uses of black tea. Today, the editor has carefully summarized the knowledge about dark tea so that you can better understand its benefits!

1. Who should drink more black tea?

Social workers, seniors, obese people, office workers and people with frequent constipation should all drink black tea regularly.

2. Why did mainlanders not like to drink black tea in the past?

The first major effect of black tea is to scrape oil. Unlike frontier herdsmen who eat beef and mutton every day, people in the mainland did not have enough to eat before the reform and opening up. What they needed in their stomachs was oil and water. Drinking black tea to scrape oil was a no-no. Black tea is thick, old, black, and looks very ugly. It is not difficult to understand that people in the mainland disdain the black tea that frontier herdsmen regard as their life drink.

With the improvement of material living standards, especially among modern urbanites, due to overnutrition, unreasonable lifestyles and dietary structures, more and more people in China are suffering from affluence and sub-health conditions (which has attracted great attention from the Ministry of Health and the world). However, the health of frontier herdsmen is as good as before, and the incidence rate of "three highs" is the lowest in the country. At this time, people have paid great attention and attention to the mysterious tea.

3. Why is it said that black tea can reduce the "three highs"?

Modern scientific research has found that dark tea is beneficial to human health. Its main functions are to control blood pressure, blood sugar, blood lipids and weight. Fuzhuan tea has obvious effects on reducing stress, lowering lipids, and lowering blood sugar. It is very helpful in controlling body fat and weight. This has long been proven by people's practice; in addition, dark tea extract has an inhibitory effect on the spread of gastric cancer cells and liver cancer cells.

4. Why can black tea lower blood pressure and blood sugar?

Theanine in dark tea can inhibit the rise of blood pressure; alkaloids and flavonoids can relax blood vessel walls, increase the effective diameter of blood vessels, and lower blood pressure by dilating blood vessels; theaflavins can soften blood vessels and effectively remove porridge-like substances in the blood vessel walls, and are known as cardiovascular "scavengers."

The unique tea polysaccharide in dark tea has an insulin-like effect and can reduce blood sugar levels in the human body. Research has proven that: 7 hours after tea polysaccharide was injected into mice, their blood sugar levels dropped by 70%.

5. Why is black tea said to be able to lower blood lipids?

Tea polyphenols and their oxidation products in dark tea can dissolve fat and promote the excretion of lipids, thereby lowering cholesterol in the blood, thereby reducing fat deposition on arterial blood vessel walls and reducing the incidence of arterialization; it can also activate protein kinases, accelerate lipolysis, and reduce fat content in the body.

Scientists have found through human experiments that compared with people who drink ordinary water, people who drink tea consume an average of 67 joules more calories per day and have a 12% higher fat oxidation rate. This proves that black tea has the effect of lowering fat and losing weight.

From May 1990 to May 1991, the Chinese People's Liberation Army General Hospital observed 55 hyperlipidemia patients among 155 veteran cadres in a cadre rest center who took Anhua dark tea for 180 days (3 grams per day). Among them, 50 patients who drank dark tea had a significant decrease in blood lipid content and blood peroxide activity.

6. Can regular drinking of black tea prevent fluorosis?

Fluorine is one of the important trace elements in the human body and an indispensable component of teeth and bones. A small amount of fluoride can promote the resistance of tooth enamel to bacterial acid corrosion and prevent dental caries. According to statistics, in areas with high fluoride intake, the rate of osteoporosis and the incidence of dental caries among the elderly will decrease.

Everything is relative. A lack of fluoride is harmful to the human body, and an overdose is equally harmful. As long as the fluoride in the body does not exceed the normal range (≤50mol/L or 4mg/day), you can eat it with confidence.

7. Why can drinking black tea warm the stomach?

Dark tea is a fully fermented tea, and is processed by autoclaving. The caffeine that irritates the stomach is reduced by steaming, and the fermented components of dark tea have been decomposed and no longer irritate the gastrointestinal tract. Dark tea is rich in warm substances such as theaflavins, and drinking it hot has a good stomach-warming effect.

8. Will drinking black tea affect sleep?

Black tea does not cause insomnia. Compared with green tea and black tea, the caffeine content in black tea is significantly reduced, while the content of tea polysaccharides and gallic acid is significantly increased. Therefore, drinking black tea will not cause insomnia. Domestic and foreign studies have shown that dark tea has a significant soothing effect.

9. Under certain conditions, black tea will become more fragrant as it ages?

During the storage of dark tea under suitable conditions, due to the influence of probiotics, moisture and heat, auto-oxidation and other comprehensive factors, the internal components of the tea undergo a series of changes. The bitter and astringent substances decrease, the sweet substances increase, and the soup becomes redder and brighter, thus improving the quality and health effects of dark tea.

10. What are the applications of black tea in life?

　① Treating enteritis is a major effect of black tea. In particular, aged black tea has a good effect on treating chronic enteritis.

② Dark tea has an obvious "heat-clearing and detoxifying" effect. Especially drinking dark tea after drinking has a very obvious hangover effect.

　③ Black tea can help digest food and remove greasiness. It has the effects of "eliminating food that has accumulated in the food", "eliminating accumulated food", "eliminating fishy meat food, and relieving the heat of highland barley".

④ Black tea has the functions of "laxative", "facilitating bowel movements, and clearing the large and small intestines".
