Is it true that precious green tea has a higher zinc content than other types of tea when it is harv

Yes, spring tea is the time when the nutrients in tea are most abundant after a winter of recuperation.

1. Tea contains a variety of vitamins. Tea contains vitamins A, D, E, K, B1, B2, B3, B5, B6, H, C, P, and inositol. Among them, A, D, E, K are insoluble in water and are called fat-soluble vitamins, and the rest are aqueous solution vitamins, which can be fully utilized when making tea.

Vitamin C, also known as ascorbic acid, improves the body's resistance and immunity. The content of vitamin C in tea is high, generally up to 100 mg and 250 mg per 100 grams of green tea, and the content of high-grade Longjing tea can reach more than 360 mg, which is much higher than lemons, pineapples, apples, tomatoes, oranges and other fruits. Due to the fermentation process in the processing of black tea and oolong tea, the content of vitamin C is oxidized and decreased, and there are only tens of milligrams left per 100 grams of tea, especially black tea, which is even lower.

2. Tea has proteins and amino acids that the human body needs. The content of water-soluble protein in tea that can be directly absorbed and utilized by drinking tea is about 2%, and most of the protein is water-insoluble substance, which exists in tea residues. There are more than 25 kinds of amino acids in tea, among which isoleucine, leucine, lysine, phenylalanine, threonine, and valine are six of the eight amino acids necessary for the human body.

There is also histidine, which is needed for the growth and development of infants. Although the content of these amino acids in tea is not high, they can be used as a supplement to the insufficient daily needs of the human body. [Gourmet China].

3. Tea contains mineral elements needed by the human body. Tea contains a large number of elements and trace elements that are required by the human body. A large number of elements are mainly phosphorus, calcium, potassium, sodium, magnesium, sulfur, etc.; Trace elements are mainly iron, manganese, zinc, selenium, copper, fluorine and iodine.

For example, the zinc content in tea is high, especially green tea, with an average zinc content of 73 micrograms per gram of green bars, and a high of 252 micrograms; The average zinc content per gram of black tea is also 32 micrograms. The average iron content in tea is 123 micrograms per gram of dried strips; The amount in each gram of black tea is 196 micrograms. These elements play an important role in the physiology of the human body.

Drinking tea regularly is one of the important channels for obtaining these mineral elements.

4. Tea contains important nutrients - tea polyphenols. Tea polyphenols are one of nature's most powerful antioxidants. Experiments have proven:

The effect of 10ug ml of tea polyphenols can be equivalent to the effect of 200ug ml of vitamin E. Tea polyphenols can inactivate carcinogens, block the formation of nitrite amines, inhibit the growth of cancer cells, and have a certain effect on the prevention and treatment of cancer.

The zinc content in tea is high, especially in green tea, with an average zinc content of 73 micrograms per gram of green bars, and a high of 252 micrograms. The average zinc content per gram of black tea is also 32 micrograms.
