1, the benefits of men drinking black tea
1, diuresis
Under the combined action of caffeine and aromatic substances in black tea, the renal blood flow increases, the glomerular filtration rate increases, the renal microvascular dilates, and the reabsorption of water by renal tubules is inhibited, thus contributing to the increase of urine output. Drinking black tea is beneficial to eliminate lactic acid, uric acid (related to gout), excessive salt (related to hypertension) and harmful substances. And relieve edema caused by heart disease or nephritis.
2. Anti-inflammatory and bactericidal effects
Polyphenols in black tea have anti-inflammatory effects. Experiments show that catechins can combine with unicellular bacteria to coagulate and precipitate protein, thus inhibiting and eliminating pathogenic bacteria. Therefore, for patients with bacillary dysentery and food poisoning, drinking black tea is quite beneficial, and strong tea is also commonly used by the people to smear wounds, bedsores and athlete's foot.
3, detoxification effect
According to experiments, tea polyphenols in black tea can adsorb heavy metals and biological alkaloids, and make them precipitate and decompose, which is good news for modern people whose drinking water and food are polluted by industry.
4, the effect of promoting fluid production and clearing away heat
Drinking black tea in summer can quench thirst and relieve summer heat, because polyphenols, sugars, amino acids and pectin in tea react with saliva to stimulate saliva secretion and make the mouth feel moist and cool. At the same time, caffeine controls the body temperature center of hypothalamus and regulates body temperature. It also stimulates the kidneys to promote the excretion of heat and dirt and maintain the physiological balance in the body.
5, refreshing, eliminate fatigue
Through medical experiments, it is found that caffeine in black tea stimulates the cerebral cortex, stimulates the nerve center, and promotes the refreshing and concentration of thinking, thus making the thinking response more acute and enhancing memory; It also has an exciting effect on the vascular system and the heart, strengthens the heartbeat, thus accelerating blood circulation to facilitate metabolism, and at the same time promoting sweating and diuresis, so as to accelerate the excretion of old and waste substances such as lactic acid (a substance that makes muscles feel tired) in the body and achieve the effect of eliminating fatigue.
In addition, drinking black tea not only has the above five health care effects, but also has the effects of preventing caries, strengthening stomach, helping digestion, delaying aging, lowering blood sugar, lowering blood pressure, lowering blood fat, resisting cancer and radiation. When going out thirsty or drinking tea at home, you might as well choose black tea.
2. How to make black tea?
1, fresh cold water for tea.
The water from the tap is full of air, which can fully guide the aroma of black tea when used to make tea. It is best to brew black tea with clear water after boiling. Tea brewed with overnight water, secondary boiling water or hot water from thermos bottle loses its original fragrance and is not suitable for making tea.
Wash the tea set with boiling water first.
Fill the teacups and teapots with boiling water, and gradually heat the teapots and teacups to avoid excessive changes in water temperature. The reason why the pot body is round is to let the tea leaves have sufficient space to expand when brewing, and the fragrance is easier to distribute.
3, the tea content should be moderate
Generally, one teaspoon (about 2.5g) of tea leaves can brew a cup of fragrant black tea, but if you want to brew more pure black tea, it is best to brew black tea with two teaspoons of red tea leaves, so as to give full play to the original flavor of black tea.
4. Boil the water and make tea immediately.
When the hot water begins to boil for about 30 seconds, the spray formed is about the size of a dollar coin, and the black tea is brewed. This temperature is the most suitable.
After the tea is brewed, it will be stuffy for a while.
Fast-brewed tea can't release the fragrance of tea for the time being, so after brewing tea, you can drink it for a period of time according to the concentration of tea. Generally speaking, the concentration of tea is divided into one to four levels, the first level is the weakest and the fourth level is the strongest, and the brewing time is reduced from two minutes to three and a half minutes.
6. Seasoning and drinking according to taste preference
People who don't like original black tea can try adding honey, milk and lemon to taste. It should be noted that although the content of tea polyphenols in black tea is low, it is light after maturity, which is suitable for people with weak stomach and intestines to drink at night. Adding some milk when drinking black tea can play a certain role in warming the stomach.
