In addition, vitamin C and vitamin E in Tieguanyin can block the synthesis of carcinogens-nitrosamines, which has a great effect on preventing and treating cancer.
3. Anti-aging

Nutritional value of Tieguanyin
After modern scientific separation and identification, tea contains more than 450 organic chemical components and more than 40 inorganic mineral elements. The organic chemical components and inorganic mineral elements in tea contain many nutrients and medicinal ingredients. The main organic chemical components are: tea polyphenols, alkaloids, proteins, vitamins, pectin, organic acids, lipopolysaccharides, sugars, enzymes, pigments, etc. The organic chemical components contained in Tieguanyin, such as tea polyphenols, catechins, and various amino acids, are significantly higher than other teas.

How to choose Tieguanyin
The identification method of Tieguanyin is to observe the appearance of the tea in a dry state and to evaluate the internal quality of the tea in a wet state (brew with water).
1. Observe the appearance
It is mainly to observe the appearance, color, uniformity and smell the aroma of the tea leaves. Tea with a plump appearance, heavy and solid, sandy green color, and pure aroma of the dry tea (tea leaves) is a top-grade tea with obvious characteristics of Guanyin. Otherwise, it is a low-grade tea.
2. Wet evaluation of quality
After the tea leaves are brewed with boiling water, their aroma, soup color, taste and leaf bottom are identified.
(1) Smell the aroma: First smell whether the aroma is prominent, and then distinguish the height, length, strength, purity and turbidity of the aroma. When smelling the aroma, a combination of hot smell, warm smell and cold smell is used. Tea with a prominent aroma, a clear and long-lasting aroma is a top-grade tea. Otherwise, it is a low-grade tea.
(2) Taste: Use a teaspoon to scoop an appropriate amount of tea soup into your mouth (not too much), and use your tongue to suck and roll it in your mouth, so that the taste cells in various parts of your mouth can make a comprehensive taste sensation. Those with a mellow taste, mellow and refreshing, thick but not astringent, and rich in the "flavor" characteristics of the variety are all top-quality; otherwise, they are inferior.
(3) Look at the color of the soup: Look at the depth, brightness, clarity, etc. of the color of the tea soup. Those with a bright orange-yellow soup color (abbreviated as mung bean soup) are top-quality; those with a dark and turbid color are inferior.
(4) Observe the leaf bottom: Pour the tea leaves brewed with boiling water (called "leaf bottom", commonly known as "tea dregs") into a plate filled with clear water and observe the leaf bottom. Those with soft leaf bottoms and obvious "green stems and green bellies" are top-quality; otherwise, they are inferior.
Storage of Tieguanyin
Generally, low temperature and sealed vacuum are required, so that the color, aroma and taste of Tieguanyin can be guaranteed in a short time. However, in actual storage, it is often the case that the tea is not stored for a long time, but the color, aroma and taste are not as good as when it is first brewed. The reason is the degree of drying after the tea is fermented.

How to eat Tieguanyin
It is best to brew Tieguanyin in a covered bowl. Try to use pure water for brewing. The water temperature is about 90 degrees. The first water is used to wash the tea and warm the cup. The second water is 15 seconds for fragrance. Each subsequent water is extended for 15 seconds.

It is best not to exceed seven times of tea. If it is spring tea, it is basically five times. After there is no obvious tea fragrance, it is tea dregs. Although it has a taste, it has no health care effect. Tieguanyin is not better as it ages. The tea fragrance and aftertaste are unique to good tea.

So it is better to taste new tea, and the best Tieguanyin Tea has acidity. If it is stored for a long time, the acidity will gradually lose.

In addition, the new tea is not the newer the better. Improper drinking can easily hurt the stomach and intestines. Since the new tea has just been picked and has a short storage time, it contains more unoxidized polyphenols, aldehydes and alcohols. These substances do not have much effect on healthy people, but for patients with poor gastrointestinal function, especially those with chronic gastrointestinal inflammation, these substances will irritate the gastrointestinal mucosa. People with poor gastrointestinal function are more likely to induce stomach problems. Therefore, it is not advisable to drink too much new tea, and new tea that has been stored for less than half a month should not be drunk.
In addition, new tea also contains more caffeine, active alkaloids and a variety of aromatic substances. These substances can also excite the central nervous system of the human body. Patients with neurasthenia, cardiovascular and cerebrovascular diseases should drink in moderation, and should not drink before going to bed or on an empty stomach. The correct way is to leave it for half a month before using it.
