Introduction: This article introduces the efficacy and function of red tea, drinking red tea benefits and disadvantages, red tea diet, red tea brewing and storage methods, and other knowledge.
Red tea is rich in carotene, vitamin A, calcium, phosphorus, magnesium, potassium, caffeine, isoleucine, leucine, lysine, glutamic acid, alanine, aspartic acid, and other nutrients. During the fermentation process of red tea, the chemical reaction of polyphenols makes the chemical composition in fresh leaves change greatly, and theaflavins, theophylline, and other components will be produced, and their aroma will increase significantly than that of fresh leaves, forming the unique color, aroma and taste of Red tea.
Red tea is fermented tea, which is made from the proper bud leaves of tea trees through typical processes such as withering, rolling(cutting), fermentation and drying. The name Red tea is due to its color and color of dry tea and the red color of tea soup.
Red tea was called "red tea" when it was created. During the processing of Red tea, the chemical reaction centered on the enzymatic oxidation of tea polyphenols took place. The chemical composition in fresh leaves changed greatly, and the tea polyphenols were reduced by more than 90%, resulting in the production of new components such as theafanthin and theoglobin. Aroma substances than fresh leaves increased significantly. So Red tea has the characteristics of red color, red soup, red leaves, and sweet taste.
The health benefits and functions of red tea.
✵Refreshing and eliminate fatigue: Through medical experiments, it is found that the caffeine in red tea stimulates the nerve center by stimulating the cerebral cortex, which promotes refreshing and concentration of thinking ability, and further sharpens the thinking reaction and enhances the memory. It also has excited effect to hemal system and heart, aggrandizement heartbeat, accelerate haemal circulation to benefit metabolism thereby, at the same time stimulative hair sweat and diuresis again, from this double pipe accelerates excretion lactic acid(the material that makes muscle feel tired) reach other in the body old waste material, achieve eliminate the effect of fatigue.
✵Generate saliva and clearing heat: Drinking red tea in summer can quench thirst and relieve heat, because tea polyphenols, sugars, amino acids, pectin and other chemical reactions with saliva, and stimulate salivary secretion, resulting in mouth feel moist and produce cool feeling; at the same time, theine controls the hypothalamus' temperature center and regulates body temperature. It also stimulates the kidneys to promote the excretion of heat and dirt and maintain the physiological balance of the body.
✵Prompt diuresis: Drinking red tea in summer can quench thirst and relieve heat, because tea polyphenols, sugars, amino acids, pectin and other chemical reactions with saliva, and stimulate salivary secretion, resulting in mouth feel moist and produce cool feeling; This helps to eliminate lactic acid, uric acid(associated with gout), excessive salt(associated with high blood pressure), harmful substances, and relieve edema caused by heart disease or nephritis.
✵ Anti-inflammatory and sterilization: The polyphenols in red tea have anti-inflammatory effects, and experiments have shown that catechins bind to single-celled bacteria, causing proteins to coagulate and precipitate, thereby inhibiting and killing pathogens. So red tea is good for people with bacterial dysentery and food poisoning. Red tea is also commonly used to smear wounds, bedsores and athlete's foot.
✵Detoxification: It has been proved by experiments that the tea alkali in red tea can absorb heavy metals and alkaloids, and precipitate decomposition, which is good news for modern people whose drinking water and food are polluted by industry.
✵Strong bones: On May 13, 2002, the American college of physicians published a survey of 497 men and 540 women who had been drinking red tea for more than 10 years. To prevent osteoporosis in women, it is recommended to take a small cup of red tea every day for several years. If add lemon in red tea, strong skeleton, the effect is stronger, in red tea can also add a variety of fruits, can play a synergistic role.
✵Anti-aging: Over the past five years, the U.S. government has funded more than 150 studies of green and red tea and their chemical composition, which suggest that the antioxidants in green and red tea can completely disrupt the pathways of chemicals in cancer cells. "There's a lot of evidence to support the idea," said Dr. Murray McMahon, director of vascular epidemiology at Beth Israel deaconess medical center in Boston. "red tea has about the same benefits as green tea, but red tea has more complex antioxidants than green tea, especially for the heart," Dr. Mitterman said. Red tea has a stronger anti-aging effect than garlic, broccoli, and carrots, US magazine reports.
✵Nourishing the stomach and protect the stomach: People who drink green tea before eating may feel uncomfortable in their stomach. This is because tea polyphenols, an important substance contained in tea leaves, have an astringent effect on the stomach, which is even stronger when the stomach is empty. Not so for red tea. It is baked by fermentation. Red tea will not hurt your stomach but will nourish it. Often drink the red tea that adds sugar, add milk, can diminish inflammation, protect the gastric mucous membrane, also have certain effect on treating the ulcer.
✵Anticancer: The idea that tea has anti-cancer effects is very popular and has been explored by researchers around the world. Red tea, like green tea, has been found to have powerful anti-cancer effects.
✵Diastolic blood vessels: A study in the American medical community has been linked to the red tea. The study found that people with heart disease who drank four cups of red tea a day increased their blood vessel relaxation from 6 percent to 10 percent. The average person's comfort level increased by 13 percent after being stimulated.
Red tea taboos, drinking red tea disadvantages.
1. People with stones and tumors: red tea is generally not allowed in patients with stones.
2. People with anemia, mental weakness, and insomnia: the refreshing effect of red tea may make their insomnia worse.
3. Usually emotional or sensitive, poor sleep and weak body. Because red tea is a great pick-me-up.
4. A person with a hot stomach: because red tea is a warm tea, warm the stomach.
5. Thick tongue, bad breath, easy to pox, red eyes: red tea belongs to "hot nature", those who are afraid of getting angry should not drink red tea.
6. People taking medication: red tea will spoil the medicine.
7. Period of women, because in the period iron may turn deficient, red tea tannic acid will hinder the absorption of iron in food.
8. Pregnant women, because the caffeine in red tea will increase pregnant women's heart, kidney load, will cause pregnant women's discomfort.
9. Lactation women, because the tannic acid in red tea affects the blood circulation of the mammary gland, will inhibit milk secretion, affects the quality of breastfeeding.
10. Menopause women, because of the tea polyphenols in red tea may stimulate menopause heartbeat, poor sleep quality, and other phenomena.
✵The difference between red tea and green tea:
Red tea is fully fermented; green tea is not. Red tea is warm, cold, warm stomach, green tea is cool, heat, refreshing; indeed, they are made in different ways.
Red tea is fully fermented tea: The preparation process does not kill the cyanine, but directly withers, kneading and cutting, and then carries on the complete fermentation, causes the tea polyphenols contained in the tea leaves to oxidize into the tea red pigment, thus forming the dark red tea leaves and red tea soup unique to red tea. indeed, they are made in different ways. Tea classification, according to a variety of different standards, there are different ways to distinguish.
The most general and most commonly used, is based on the degree of fermentation and preparation, divided into six tea categories: red tea, green tea, yellow tea, white tea, green tea, red tea: fermentation degree of 80 ~ 90% of the full fermented tea. The preparation process does not kill the cyanine, but directly withers, kneading and cutting, and then carries on the complete fermentation, causes the tea polyphenols contained in the tea leaves to oxidize into the tea red pigment, thus forming the dark red tea leaves and red tea soup unique to the red tea. It must be noted, however, that red tea is not called "red" tea in English, but black tea. Green tea is made from suitable new shoots of tea trees through typical processes such as defoliation, rolling and drying. Its dry tea color and brew after the tea soup, the bottom of the leaves to green color, so the name of green tea.
