Is drinking tea good for the body What are the benefits of drinking tea for the human body

Why drinking tea is not the same as drinking boiled water, the ancients have long understood this in practice, the Tang Dynasty "Materia Medica" pointed out: "Zhuyou is the medicine of all diseases, tea is the medicine of all diseases", the Japanese "Eating Tea Health Record" also said, "Tea is the fairy leaf of health, the magic of prolonging the order", and European poets also called tea "the drink of the soul". However, it was not until the early 20th century that the real secrets hidden in it were gradually revealed and confirmed by scientists, medical scientists, and pharmacists around the world.

It turns out that tea contains more than 500 kinds of chemical components, the main of which are tea polyphenols, caffeine, proteins, amino acids, fats, carbohydrates, aromatic compounds, various cone biotics and minerals, etc., and these components can interact with each other, harmonize consistently, and each exert its unique natural effect. Tea has the functions of quenching thirst, clearing the heart and eyes, diuresis and detoxification, eliminating food and greasy, supplementing nutrition, relieving fatigue, strengthening the heart and lowering blood pressure, anti-cancer and anti-radiation, preventing arteriosclerosis and hypertension, and delaying human aging.

Of course there is, drinking tea can be beautiful, **, but the premise is that you have to insist on drinking.

Green tea retains more of the natural substances in the fresh leaves. More than 85% of the tea polyphenols and caffeine in the fresh leaves are retained, about 50% of the chlorophyll is retained, and the loss of vitamins is also less, thus forming the characteristics of green tea clear soup with green leaves, fresh taste and strong astringency. Scientific research results show that the natural substances retained in green tea have anti-aging, anti-cancer, sterilization, anti-inflammatory and other effects that are unmatched by other teas, and are suitable for young people, computer workers, and people who smoke and drink.

For tea, only China has the most say in the whole world, China is the homeland of tea, and it is also the first country in the world to plant and use tea, as early as the Shennong period, tea and its medicinal value have been discovered by our ancestors, and gradually evolved from medicinal use to daily life drink. Tea has accompanied the ancient Chinese nation through a long history. Open the book of the development of Chinese civilization for 5,000 years, and you can smell the fragrance of tea from every page.

Originally, our ancestors drank tea for the purpose of: detoxifying, eliminating food, clearing the heart, benefiting thinking, and reducing sleep.

Experts believe that tea also has many benefits for people: because tea contains a variety of antioxidants and antioxidant nutrients, which have a certain effect on eliminating free radicals. Drinking three or two cups of tea a day can play a role in preventing aging, preventing cancer, refreshing the mind, and eliminating food and diuresis.

The reason why many people like to drink tea is that the tea polyphenols, caffeine, lipopolysaccharides, and vitamins contained in tea can play a role in health care and pharmacology, and can also relieve greasy and sleepy. At the same time, tea tasting is also a status symbol.

The benefits of drinking tea for people are:

3. Keep in shape. In the Tang Dynasty's "Collection of Materia Medica", the discussion on tea once mentioned that "eating for a long time makes people thin", and modern scientific research has confirmed this. The caffeine in tea can promote gastric juice secretion, help digestion, and enhance the body's ability to decompose fat.

Foreign studies have also shown that regular tea consumption can reduce waist circumference and reduce body mass index (BMI), thereby helping to prevent diabetes and cardiovascular and cerebrovascular diseases.

In fact, tea contains more substances that help reduce calcium loss, including fluoride, phytoestrogens and potassium. A study in Taiwan found that people who drink tea regularly have higher bone density and a lower chance of hip fracture.

Tea is edible, but be cautious?

For Chinese, drinking tea is a habit for many people, but a few people have a penchant for eating tea. So, is eating tea good for your health?

On December 22, this reporter came to Zhang Yiyuan's tea shop near Qingnian Road in Chaoyang District, Beijing. The reporter asked the clerk, is it nutritious to eat tea or drink tea? The clerk told reporters that according to the habits of Chinese, there are still more people who drink tea, and fewer people eat tea.

However, tea can be used to make mooncakes or snacks, or to be held in the mouth to drive away the odor in the mouth. A consumer also told reporters that he heard that tea is edible, but drinking tea is very tasteful, and it is estimated that there is no taste in eating tea, and since it is not delicious, he will not eat it

A professor at Beijing University of Traditional Chinese Medicine said that the nutrition of tea consists of two parts: water-soluble and fat-soluble, the latter is insoluble in water and will always remain in the tea no matter how many times you drink it. Therefore, only by eating tea can we better absorb the nutrients of tea. The water-soluble nutrients in tea mainly include catechins, vitamin C, and amino acids. Fat-soluble nutrients mainly include vitamin E, carotene, dietary fiber, minerals, and chlorophyll

In substances that are insoluble in water, vitamin E has an anti-aging effect; Catechins are an important nutrient. The tea polyphenols contained in catechins have a strong effect of eliminating oxygen free radicals and anti-aging. Studies in recent years have also proved that it can not only eliminate pigmentation, but also reduce cholesterol and blood lipids, kill leukemia cells and prevent epidemics.

Therefore, it is advisable to "eat tea" appropriately to make up for this shortcoming, that is, to make tea into ultra-fine powder and add it to various foods, such as tea-containing tofu, tea-containing noodles, tea-containing cakes, tea-containing candy, tea-containing ice cream, etc. After eating these tea-containing foods, you can obtain the fat-soluble vitamin nutrients contained in the tea and better play the nutritional value of tea

However, there is also a bad side to eating tea, Ms. Zhang of the Beijing Tea Quality Inspection Station said that there will be pesticide residues and heavy metal content in tea, and these harmful substances are dissolved into the water with relatively few components, but if you eat it, there will be more components absorbed by the body. Therefore, people who choose to eat tea must be cautious.
