Old Tang book? Xuanzongji: A 130-year-old monk came to Luoyang, and everyone came to ask him the secret of longevity. The monk replied, "I don't know why I live long, but I like tea." Tasting tea is drinking tea.
Tea can be used as a refreshing drink, and can also be used as a culture to appreciate the taste. But many people ignore the medicinal value of tea.
Few people know that tea was first discovered as a medicinal material. The first person to find it was Shennong.
"Shen Nong's Classic of Materia Medica" records: "Shen Nong tasted a hundred herbs and encountered seventy-two poisons every day, so he solved it with tea." Tea here is the original word of modern tea. Tea is derived from the word tea. Shennong tasted all kinds of herbs and was poisoned by eating tea.
Since tea has medicinal value, what is its function? What does tea have to do with people's health?
First, beauty, anti-aging
Aging is a process that everyone will go through. But everyone wants their skin or body to age slowly. In order to slow down the pace of aging, many people will buy expensive health products to eat, or buy expensive cosmetics to smear.
But in fact, there are substances in tea that can delay aging and beauty and skin care.
1, contains vitamins and minerals.
Tea contains many vitamins (A, B 1, B2, C, E, etc. ) and minerals (potassium, sodium, calcium, phosphorus, magnesium, manganese, copper, zinc, selenium, etc. ).
The vitamin content in tea is even higher than that in many vegetables and fruits. The content of vitamin B 1 is 6 times higher than that of apple.
Vitamins and minerals are essential nutrients for human body, which can protect the health of skin and internal organs. Moreover, minerals are also important substances in bones and various body tissues, which can regulate the functions of the body.
2. Tea also contains catechins.
Free radicals and peroxides are the main factors leading to human body and skin aging. Catechin is a natural antioxidant, which can effectively fight free radicals and scavenge peroxides.
Therefore, drinking tea regularly can not only play a cosmetic role, but also delay the aging of the body.
Washing your face with tea often can also improve skin metabolism, increase skin nutrition, eliminate chloasma and delay the generation of skin wrinkles.
Second, reduce blood fat, blood sugar and lose weight
Hyperlipidemia and hyperglycemia have always been the disease signals that people attach great importance to and pay attention to. They are easy to cause cardiovascular and cerebrovascular diseases, coronary heart disease, atherosclerosis and other diseases, and there are risks to health that cannot be ignored.
1, tea polyphenols, tea polysaccharides
People with high blood lipids are mainly due to the high triglyceride content in blood, and tea polyphenols, tea polysaccharides and other components in tea can effectively reduce triglyceride in blood.
And tea polyphenols can inhibit the synthesis of cholesterol in cells. Tea polysaccharide can also enhance the excretion of cholesterol through the liver.
Therefore, drinking tea can effectively reduce the cholesterol content in the body, so as to achieve the effect of lowering blood fat and losing weight.
2. Vitamin C and B 1
Hyperglycemia can easily lead to diabetes, and complications such as pancreatic failure, dehydration, electrolyte disorder and impaired renal function. Diabetic people will have many taboos in their diet, which is very painful.
Most people with high blood sugar are due to insufficient insulin secretion, which leads to high blood sugar.
Drinking tea can reduce blood sugar, because vitamin C and B 1 in tea can promote the catabolism of sugar in the body. Moreover, the active ingredients in tea can stimulate the production of insulin.
Green tea, black tea and Pu 'er all have hypoglycemic effects. Among them, green tea is the best tea. But because green tea is cold, it is not suitable for people with bad stomach. Then you can choose black tea or Pu 'er to drink, and you can achieve a similar effect.
Third, radiation resistance.
Many people know that playing with mobile phones has radiation, but in fact, radiation is not limited to mobile phones, it exists in many corners of our lives.
Such as computers, TV towers, microwave ovens and other household appliances, will form electromagnetic radiation. Although electromagnetic radiation is a kind of radiation with relatively less influence than other radiation such as nuclear radiation. However, it is still one of the pathogens that endanger human health today, and it is an invisible killer that threatens our health.
Electromagnetic radiation can easily reduce the number of white blood cells in the blood. A decrease in the number of white blood cells will reduce the body's immunity. Electromagnetic radiation will also increase the risk of cancer and cause irreversible damage to body DNA.
1, tea polyphenols, lipopolysaccharide
Tea polyphenols, lipopolysaccharide and other components in tea can not only effectively improve human immunity, but also increase the number of white blood cells.
2. Tannic acid
Therefore, people who often use computers and mobile phones suggest drinking more green tea. This can reduce the harm of radiation to human body.
Fourth, get rid of bad breath.
There are many reasons for bad breath, but most of them are due to the growth of bacteria in the mouth, which produces odorous gas.
Frequent gargling with strong tea or chewing tea leaves can eliminate bad breath.
Because tea polyphenols contained in tea can kill bacteria that cause bad breath, this bacteria will produce unpleasant volatile sulfur compounds.
Tea with good effect of eliminating halitosis is:
Osmanthus tea, mint tea, agastache tea, water chestnut tea, pomegranate tea, loofah tea, bamboo leaf tea and so on.
But there are many reasons for bad breath. The above tea is suitable for halitosis caused by bacteria. If it is bad breath caused by stomach trouble, you can chew tea with its single taste. Single tea is suitable for patients with halitosis caused by rising stomach heat, and has the effect of clearing stomach heat.
Although tea can not completely replace the role of drugs, its medicinal value can not be ignored. Now most people are in a sub-health state. Drinking tea in moderation can help us improve our health rate.
Tea is not a scarce commodity in China, and its price is low, which is affordable for the general public. Moreover, drinking tea has little toxic and side effects, and it can become a very healthy health drink as long as it is drunk in moderation.
