Scientific determination shows that the tea contains a smashing. It is closely related to human health and the trace element, which has the function of protecting the heart, lowering blood pressure and preventing cancer. Regular drinking, good for your health. Only need to pay attention to some of the tea, or only the loss of nutrition.

A, don't pour out the first cup of tea.

In real life, many people always used to make the first cup of tea is the first cup of tea drained, reason not health. This is actually a misunderstanding.

We know that from the tea picking to the production process is a complex process, fixing, drying, roasting and several processes, but also with a 100 - 200 DEG C high temperature fire. Alone tea picking girl is not the kind of surface cleaning, washing hands dirty girl, even tea entities in the growth process of bacteria, dirt in multi-channel processes "sifting", losing room alive.

In addition, there are people who worry about whether there is a pesticide in tea, the practice has proved that this fear is unnecessary. Had tea experts deliberately sprayed with pesticides, picking tea, handed over to the processing of tea master, tea evacuation to a laboratory, it was found, night drug residues is zero. Originally, these residues of pesticides in the production process is decomposed. Besides, the tea is generally not to spray pesticides in tea harvested in late. This is enough to explain that the tea is still very sanitary.

On the contrary, that of tea health doubt easily drained first cup of tea is very wrong, the first cup of tea with beneficial ingredient, in vain drained is really too bad the.

Two, should not be used to make tea mug.

Tea contains a large number of tannic acid, theophylline, aromatic oil and a variety of vitamins, should with 70 - 80 DEG C boiling water, if in a thermos cup of tea, make tea soak for a long time in high temperature, the temperature of the water, just as with slow fire boiling in general.

Tea in the vitamin will is destruction, aromatic oil volatilization, tannic acid, theophylline was leached in large amounts, not only greatly reduces the nutritional value of tea, but also make the tea fragrance free, tea bitter, harmful substances increased.

If the long-term drinking this tea, it will endanger the health, resulting in the digestive, cardiovascular, nervous and hematopoietic system of a variety of diseases.

Three, tea, do not chew tea.

Some people like to drink tea, which is harmful to people's health. Because tea contains a carcinogenic benzopyrene, which is a and Aspergillus flavus, like the role of organic compounds, which can induced human normal cell chromosomal and genomic aberrations or mutation.

Originally, in the normal case, tea does not contain benzopyrene, just because of the contamination of the air, soil, water, etc., or in the tea frying process, benzo pyrene. But it is difficult to benzo pyrene dissolved in water, and tea content is extremely low, so the tea does not have what risk.

But tea, especially tea is not a bubble while floating on the water, some people used the tea chew and swallow, when the tea have BAP could exceed the total amount (1.5 mg), there is the risk of cancer.

So please don't chew tea when you have tea.

Four, how to store tea.

Fresh tea, moisture absorption ability is very strong, such as improper storage, easy to mold change. South rain water is too large, the air humidity is big, more should pay attention to. Storage, to maintain the color, aroma, taste of tea.

Bought tea (not too much), should be placed in a clean, tasteless bottles, cans, boxes or barrels, with a solid seal. Light has a great influence on tea, should be put in place to avoid light, ventilated, dry place.

Tea has strong adsorption, can absorb other gas molecules from the air. Therefore, and salted fish, bacon, pepper, Yin Xiang, seafood, cigarettes, soap, camphor (pill), like stocks such as the smell of items in together, so as to avoid Chuanwei.
