        Nowadays, green tea are remarkably in season again. As the saying goes, green tea are remarkably expensive as gold. Remarkably tea price is high, and some of the famous tea such as west lake longjing, dongting "biluochun" price as high as 6000 ~ 8000 yuan per kilogram, some local tea market price per kilogram in 800 yuan of above. And some of the white-collar workers, jinling will remarkably on the tea as a kind of fashion. So, are remarkably tea really worth? 
 
        Benefits: green tea are remarkably light pollution 
 
        Green tea is rich in a variety of nutrients, such as vitamins, proteins, amino acids, lipids, sugars, etc., containing a lot of macro elements and trace elements. Macro elements mainly phosphorus, calcium, potassium, sodium, magnesium, sulfur, etc., trace elements are mainly iron, manganese, etc. 
 
        Expert research, according to Japanese tea fresh tea's taste is mellow, the reason is that fresh tea to bud, which contains a lot of amino acids, and rarely contain polyphenols, tea tannins such as bitter substances. Tea polyphenols has antitumor, resistance mutation, antimicrobial and antioxidant to enhance immune function, and so on. Tea polyphenols in green tea are remarkably than summer picking tea polyphenol content is low. Green tea are remarkably due to the cold weather, generally do not need to use pesticides. Spring moderate temperatures, rainfall, dark brown, green leaves soft, no harm of diseases and pests. 
 
        Inadequate: polyphenols less tannin content 
 
        Due to different geographical and environment, the mineral content in tea because of the different soil conditions. But the tea nutrition is the basic consistent, but because of different varieties there are differences in content of individual elements. 
 
        Not expensive place must be better than cheap coarse tea. In strong sunlight in summer, tea tree grows rapidly, the leaves of a substantial accumulation of polyphenols and tannins, tea also became thick. When picking tea taste is more bitter, that is, we commonly known as the thick tea. Compared with the fresh tea, though thick and it tasted bitter tea, but containing tea polyphenols, tea tannin substances such as good to the body. Tea farmers tend to taste the fresh tea, for fresh tea is expensive, so often drink thick tea. But coarse tea tea farmers healthy, fresh, few people suffering from cancer, diabetes or cardiovascular disease. 
 
        However, often drinking cheap coarse tea may cause chronic fluorosis. The fluorine content of tea was increased along with the growth of leaf age, so the spring harvest of tea (green tea) fluoride to a minimum. And brick tea, the tea is made of old tea and tea stalk processing, after the test, the fluoride is generally 100 ~ 200 times of tea. Brick tea and hot tea classics boiling water after soaking, fluorine quickly dissolve out of them, it is easy to make intake of fluoride in the body is beyond the normal range (2.4 ~ 5 mg/l), resulting in chronic fluorosis. So, daily tea drinking moderate price good quality. 
 
        Tip: some people cannot drink strong tea 
 
        The elderly The old tea shoulds not be too thick. Contains tannic acid in tea, can be combined with calcium in the body, form the crystallization, may cause loss of calcium. The old man is more suitable for drinking tea. Because coarse tea polyphenols, tea tannins in tea, tea polysaccharide content is higher than fresh tea. Tea polyphenols can inhibit damage caused by free radicals in the body, has anti-aging effect, it also could interrupt nitrosamines carcinogens, such as the damage to the body. Tea tannin can reduce blood fat, prevent hardening of the arteries, keep blood flowing, maintain the normal functions of heart head blood-vessel. Tea polysaccharide can relieve and relieve symptoms of diabetes, have fall hematic fat, fall blood pressure, and so on. 
 
        Children do not promote preschool children drinking tea. Tea of theophylline can cause nervous system excitement, infants and young children of neural excitation adjustment ability is weak, after drinking tea may appear the heartbeat is accelerated, which consumes energy. If drinking tea may appear to urinate at night and insomnia, affect child development. Tannic acid and theophylline into the body, still can inhibit children's absorption of calcium, iron, magnesium and other trace elements. 
 
        Pregnant women in tea tea tannins in the intestinal tract and food or drug combination of iron, affect the body's absorption of iron. Tea grows, the weaker in iron absorption ability. Loss of iron and is not added, can lead to iron deficiency anemia. Pregnant women with iron, calcium, magnesium, zinc and other trace elements needed is greater than the general population, drink strong tea can affect these trace elements absorption. 
 
        Make tea 
 
        Tea brewing not more than four times 
 
        To often clean tea pot, tea scale may contain a variety of metal or nonmetal material, such as cadmium, lead, iron, arsenic, mercury, etc. If you do not remove them, these metal material will enter the body when drinking tea, and the protein, fat and vitamins in food nutrition combination, precipitation in the generation of refractory, hinder the absorption of nutrition. 
 
        Bubble tea should not be too many times. General: three or four tea polyphenol content is very few. Tea brewing process separation can taste the best. Generally speaking, the bigger the particle shape of the tea, the slower nutrients precipitation; The smaller the particle, the more rapidly the precipitation. 
 
        Use of pesticides in the production of tea in our country are mostly very low water solubility, calculated on tea 10 grams per person a day, even if 1 mg/kg of residual tea brewing, and only 0.0001 mg, intake of pesticides, the world health organization (who) is one of the thousands of points allowed intake every day. The leaching rate of heavy metal lead in tea also low, as long as the purchase normal manufacturer of tea, its content will not exceed the national standard.
