The main functions and functions of green tea are as follows:
Recently, the United States has one study, green tea catechins have strong anti oxide features, skin care products containing green tea composition after application on the skin, even when sun exposure can cause sunburn so, relaxation and Rough peroxide is reduced by about 1/3. This proves that the ingredients in green tea have sun protection.

Because tea is rich in vitamin vegetarian A former, after being absorbed by the body can be quickly converted into vitamin A. Vitamin A can synthesize Rhodesian, making Eyes in the dark light, see things more clearly. Therefore, green tea can not only eliminate computer radiation, but also protect and improve eyesight .
3. Reduce fat
Drinking tea can lower blood lipids and cholesterol and make the body lighter. This is because the comprehensive coordination of phenolic derivatives, aromatic substances, amino acids, and vitamins in tea, especially the combined action of tea Polyphemus, theophylline and vitamin C, can promote fat oxidation and help digestion, Reduce fat and lose weight.
4. Anti- halitosis
Green tea contains fluorine, in which catechins can inhibit cariogenic bacteria and reduce the occurrence of plaque and periodontitis . The tannic acid contained in the tea has a bactericidal effect and can prevent food waste from multiplying bacteria, so it can effectively prevent bad breath.
The antioxidants contained in green tea help fight aging. Because of the body’s metabolic process, if it is peroxidized, it will produce a lot of free radicals, which are easy to age and cause cell damage. SOD (superoxide disproportionation) is a free radical scavenger, which can effectively remove excess free radicals and prevent the damage of free radicals to the human body. The catechins in green tea can significantly increase the activity of SOD and scavenge free radicals.
Studies have shown that catechins in green tea have an inhibitory effect on some of the bacteria that cause disease in humans, while not harming the reproduction of beneficial bacteria in the intestine, so green tea has the function of intestinal rectification. Studies have shown that tea polyphenols can remove excess harmful free radicals in the body, the body can be regenerated α-VE, VC, GSH, SOD , such as efficient antioxidants to protect and repair complex antioxidant system, immune enhancement , Has a significant effect on anti-cancer and anti-aging.
7. Prevent stomach disease
A study shows that drinking green tea can prevent chronic gastritis and gastric cancer . The study found that the longer people who drink green tea have lower rates of chronic gastritis and stomach cancer, those who love green tea have a 48% lower rate of stomach cancer than those who do not like tea.
Green tea has an inhibitory effect on certain cancers, but its principles are limited to the inference stage. To prevent cancer, drinking more tea is bound to have its positive encouragement.
9. Promote digestion
Recent studies have shown that green tea can help improve indigestion, such as acute diarrhea caused by bacteria, and drink a little green tea to reduce the condition.
Experts specially remind: tea is not as fresh as possible. From a nutritional point of view, the freshest tea leaves are not necessarily the best in terms of nutrients, because the so-called new tea refers to the tea leaves that are less than a month after being picked. Because these tea leaves have not been placed for a period of time, some substances that have adverse effects on the body , Such as polyphenols, alcohols, and aldehydes, have not been fully oxidized. If you drink new tea for a long time, there may be uncomfortable reactions such as diarrhea and bloating.
After understanding the efficacy and role of green tea, many netizens may not know how to store green tea. Let’s take a look with the editor.
Green tea is a loose and porous hydrophilic substance, so it has a strong hygroscopicity. When storing green tea, a relative humidity of 60% is more suitable, and if it exceeds 70%, mildew spots will occur due to moisture absorption, which will then be acidified and deteriorated.
2. high temperature:
The best storage temperature of green tea leaves is 0-5 ℃. If the temperature is too high, the amino acids, sugars, vitamins and aromatic substances in the tea will be decomposed and destroyed, which will reduce the quality, aroma and taste.
Sunlight will promote the oxidation of pigments and esters in green tea leaves, and it can decompose chlorophyll into pheophytin. Green tea leaves are stored in glass containers or transparent plastic bags. After being exposed to sunlight, their internal substances will react chemically to deteriorate the quality of green tea leaves.
Chlorophyll, aldehydes, esters, vitamin C, etc. in green tea leaves are easily combined with oxygen in the air. The oxidized green tea leaves will make the green tea tea soup reddish and darken, greatly reducing the nutritional value.
Green tea leaves contain high-molecular palmase and terpene compounds. This kind of material is very unstable and can absorb odor widely. Therefore, when tea is mixed with odorous items and stored, it will absorb the odor and cannot be removed.
