If you want to live forever, you must preserve your health and prolong your life. This is human knowledge. Asparagus contains more nutrients such as protein and vitamins than other vegetables and fruits. It has high nutritional value. Studies by Chinese and foreign scientists show that the medicinal value of asparagus is far higher than its nutritional value. It is recognized that asparagus has unique anti-cancer and anti-aging effects and can improve human immune function. Therefore, asparagus has been declared as one of the top ten healthy vegetables by the World Health Organization.
Li Shizhen's Compendium of Materia Medica once recorded asparagus, saying that asparagus, also known as small white cloth, can accumulate heat, induce diuresis, moisten the lungs, relieve cough, eliminate phlegm and kill insects. Modern medical research has proved that asparagus can prevent cancer, diabetes, hypertension and cystitis. Professor Wu, academician of China Academy of Sciences and director of the State Key Laboratory of Molecular Oncology, introduced asparagus in the book "Overcoming Cancer": asparagus has preventive and therapeutic effects on all kinds of cancer patients, especially on bladder cancer, lung cancer and skin cancer. The experiment of Institute of Medicine of Shandong Academy of Medical Sciences has proved that asparagus extract can inhibit the activity of topoisomerase on cancer cells and promote DNA double-strand breaks of cancer cells. However, due to the obvious dose-effect correlation, it has no effect on human normal cells with low topoisomerase depth, which makes asparagus the most ideal choice for anti-cancer, which can directly inhibit and kill cancer cells and has no toxic and side effects on normal cells. Further research by scientists proves that asparagus is rich in tissue protein nucleic acid, folic acid, trace element selenium and free asparagine, which can effectively inhibit the growth of cancer cells and the synthesis of cancer macromolecules, and form biochemical obstacles to human cancer cells, thus preventing the growth, proliferation and infiltration of cancer cells. Modern medical research results show that coumarin and other components contained in asparagus can reduce blood sugar. If middle-aged and elderly patients with type II diabetes regularly take asparagus products, they can not only improve the symptoms of diabetes, but also have a good preventive and therapeutic effect on diabetes complicated with hypertension, retinal damage and obesity. Asparagus extract can effectively change the proportion of lymphocyte subsets in human body, improve the activity of various immune cells, and thus enhance the immune function of the body. Therefore, some people in the medical field also call it biological response regulator.
Efficacy of asparagus tea: ① Three nutritional values: 1, high vitamins, high cellulose and high protein. 2, low sugar, low fat. 3. It contains a variety of essential macroelements and microelements. ② Four health functions: 1. Anti-cancer and anti-cancer effects: it can inhibit the activity of topoisomerase, directly kill cancer cells, destroy telomerase of cancer cells, prevent cancer cells from proliferation and division, activate anti-cancer genes, and regulate signal transduction to normalize cell growth. 2. Therapeutic effect on cardiovascular and cerebrovascular diseases: Asparagus can inhibit hypertension, prevent and treat arteriosclerosis, reduce blood lipid and cholesterol, and treat tachycardia, which has a strong diuretic effect. 3. Effect on human immune system: Asparagus can reduce the content of circulating immune complex (CIC), produce thymosin, and promote the production of T cells, thus improving immune function and regulating immune mechanism. 4. Anti-aging function: It can reduce the content of lipid peroxide (LOP) in human organs and increase the activity of superoxide dismutase (SOD), thus delaying aging.
black tea
Refreshing and relieving 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.
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 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. Besides, black tea is an excellent sports drink. In addition to relieving summer heat, quenching thirst and replenishing water, if you drink it before sports (such as marathon running) that require physical strength and endurance, because caffeine in tea has a refreshing effect, it can promote the body to burn fat to supply heat energy while retaining liver vinegar during sports, so people's endurance is stronger.
be diuretic
Under the combined action of caffeine and aromatic substances in black tea, renal blood flow increases, glomerular filtration rate increases, renal microvascular dilates, and renal tubules are inhibited from reabsorption of water, thus contributing to the increase of urine volume. This is beneficial to eliminate lactic acid, uric acid (related to gout), excessive salt (related to hypertension), harmful substances and so on. And relieve edema caused by heart disease or nephritis.
Anti-inflammatory sterilization
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. People often use strong tea to smear wounds, bedsores and athlete's foot.
Detoxify
According to experiments, tea polyphenols in black tea can adsorb heavy metals and alkaloids, and make them precipitate and decompose, which is good news for modern people whose drinking water and food are polluted by industry. In addition, black tea also has the functions of preventing caries, invigorating stomach and moistening intestines, helping digestion, delaying aging, lowering blood sugar, lowering blood pressure, lowering blood fat, resisting cancer and radiation.
nourishing the stomach
When people drink green tea instead of eating, they will feel sick to their stomachs. This is because tea polyphenols, an important substance contained in tea, have astringent taste and have a certain stimulating effect on the stomach, especially on an empty stomach. On the other hand, black tea is made by fermentation and baking. Under the action of oxidase, tea polyphenols are enzymatically oxidized, and the content is reduced, which reduces the stimulation to the stomach. In addition, the oxidation products of these tea polyphenols can also promote human digestion, so black tea will not only hurt the stomach, but also nourish the stomach. Drinking black tea with sugar and milk often can diminish inflammation, protect gastric mucosa and have a certain effect on treating ulcers.
Black tea brown
If black tea wants to fade, it mainly depends on the amount of tea and the amount of water released. Ordinary people can put 3-5 grams of tea, and the light taste can be put less, ensuring the tea-water ratio of 1: 50. That is to say, if you put 3 grams of black tea, you should brew it with 150 ml of water. Black tea and porcelain cups have the best visual and taste effects. It is recommended that you brew each cup of tea for 3-5 minutes. Black tea is not suitable for cold drinks. If it is left for too long, it will affect the effect of warming the stomach and reduce the nutrients. It is best to make black tea in an open cup. Don't wait until the water in the cup is finished before heating the water. It is best to store water at about 65,438+0/3, so as to dilute the tea leaves and keep the temperature and concentration of the tea leaves appropriate. Every cup of black tea is stored for three times, and the taste is the best.
Precautions for drinking
General preventive measures
The newer the new tea, the better. Improper drinking can easily hurt the stomach. Because new tea has just been picked, it has a short storage time and contains more unoxidized polyphenols, aldehydes and alcohols, which has little effect on healthy people. But for patients with poor gastrointestinal function, especially those with chronic gastrointestinal inflammation, these substances will stimulate gastrointestinal mucosa, and people with poor gastrointestinal function are more likely to induce stomach diseases. Therefore, it is not advisable to drink more new tea, and do not drink new tea that has been stored for less than half a month. Foamed black tea
In addition, new tea also contains more caffeine, active alkaloids and various aromatic substances, which will also excite people's central nervous system. Patients with neurasthenia and cardiovascular and cerebrovascular diseases should drink in moderation, not before going to bed or on an empty stomach. The correct way is to leave it for half a month before using it. Don't take medicine with tea; Do not drink tea before and after taking the medicine 1 hour. Ginseng and American ginseng should not be eaten with tea. Avoid drinking strong tea to relieve hangover; It is not advisable to drink tea before meals; Avoid drinking tea immediately after meals; Girls should avoid drinking strong tea.
Black tea is good for women.
Qingyade black tea feast
The American Heart Association once concluded that black tea is "one of the drinks rich in flavonoids, which can eliminate free radicals, have anti-acidification effect and reduce the incidence of myocardial infarction". The results show that a cup of black tea can even play a stronger anti-acidification role than garlic, broccoli, carrots and Chinese cabbage for specific free radicals. The drinking method of acid-resistant black tea is to drink 2 ~ 3 cups of black tea every day. Selenium, vitamins c, e, a, etc. They are all anti-acidification substances, and black tea will be more effective if eaten with foods rich in these substances. Drinking black tea with vegetables, fruits, butter, milk and eggs at the same time is called a healthy and reasonable eating habit. But at the same time, we should also pay attention to avoid eating too much calories and sugar. Black tea also has various antibacterial effects to prevent colds. Flavonoids in black tea have antibacterial effects such as killing poisonous bacteria in food and making influenza virus infectious. In addition to preventing colds, some people gargle with black tea when a cold causes a sore throat.
It is best to drink black tea often in winter.
When people drink green tea instead of eating, they will feel sick to their stomachs.

Black tea is fermented and baked, and tea polyphenols are enzymatically oxidized under the action of oxidase, so the content is reduced and the irritation to the stomach is also reduced. Black tea not only won't hurt the stomach, but also nourish it. Drinking black tea with sugar and milk often can diminish inflammation and protect gastric mucosa, and also has a certain therapeutic effect on ulcers. However, black tea is not suitable for cold drinking, which will affect the effect of warming the stomach, and may also reduce the nutritional content because it is left for too long.
