As one of the world's top three beverages, tea has entered the bone marrow of Chinese.
It originated in China, prevailed in the world, thousands of years of history, tea is no longer a simple drink, behind a strong cultural heritage.
From a health perspective, tea is also a healthy drink.
What are the health benefits of tea?
First, low calories
Whether it is fat, sugar, or calories, its calories are almost negligible, compared to those sugary drinks, the advantages of tea are too powerful.
Second, refresh the mind
Tea contains caffeine, and this substance is also the "active ingredient" of coffee, so for friends who are not used to drinking coffee, drinking a cup of tea can also refresh the mind.
Third, tea polyphenols
The biggest feature of tea is that it contains tea polyphenols. In different tea leaves, the specific types and contents of tea polyphenols are obviously different.
Of course, tea polyphenols, theanine, etc. can reduce the possibility of suffering from Diseases such as Alzheimer's disease, ovarian cancer, heart disease, kidney stones, etc., which is much lower than that of people who do not drink tea.
Of course, according to the modern concept of evidence-based medicine, these findings are far from enough as evidence, but it does not prevent people from being a healthy drink.
Although drinking tea has many benefits, these teas are best not to drink
Many people especially like to drink tea every day, hoping to achieve the role of health through drinking tea.
However, when drinking tea, there are several kinds of tea that must not be drunk, otherwise it will have a greater harm to health.
First, over-hot tea
The mucous membranes of the human body's mouth, esophagus and stomach can only withstand a temperature of about 60 degrees, and if the temperature of the tea exceeds 65 degrees, it will directly cause the mucous membranes in these parts to suffer burns.
Especially when drinking tea, it will cause the mucous membrane to be burned, and it is easy to burn.
However, the mucous membranes in these areas have a self-healing function, and if they are only occasionally burned, it will not cause health damage. If this phenomenon occurs for a long time and many times.
The mucous membranes in these areas will cause a series of lesions due to burns, such as ulcers or inflammation, and even lead to abnormal proliferation of the mucous membranes in these areas, which will induce the emergence of cancer.
Second, overnight tea
After the tea leaves are soaked for a period of time, some of the vitamins, tea polyphenols, caffeine, folic acid and other components contained in it will be lost.
Drinking such tea has no health benefits. During the process of soaking tea, some sugars and proteins contained in tea will breed mold or bacteria, which can easily cause bloating or abdominal pain.
Of course, overnight tea will have some peculiar smells, so basically not many people save to this point.
Third, raw tea
The so-called raw tea refers to tea that has not undergone any fermentation and drying after the tea leaves have just been picked.
Raw tea contains alkaloids, tannic acid and other substances are particularly rich, if you drink such tea, it will make people's nerves greater stimulation, resulting in an increase in heart rate.
For people with bad stomach, raw tea will also cause great irritation to the gastrointestinal tract, causing some digestive tract diseases.
Fourth, strong tea
For some people who are mentally weak or after drinking, they like to drink some strong tea, hoping to play a role in refreshing and sobering up, which is wrong.
The taste of strong tea is very bitter, and it contains a lot of alkali substances, which will cause great stimulation to the brain and heart. It will also cause the gastric juice to be diluted, which is easy to produce bloating, abdominal pain or indigestion.
The tannic acid substances in strong tea will combine with the iron in the body, which can easily cause the appearance of iron deficiency anemia.
5. Moldy tea
After the tea leaves are moldy, a large number of molds are produced, such as penicillic acid. After these molds enter the human body, they can easily cause diarrhea, or abdominal pain, dizziness, dizziness and other symptoms.
What kind of tea to drink, the healthiest?
There are a variety of teas on the market, but in fact all of them come from the same plant.
Just like pasta, although there are various varieties, they are all made with flour. The reason why the teas are different is mainly due to the different degrees of oxidation during the production process, resulting in different flavors of tea.
Although most advertisements will advertise that their tea is "rich" with a variety of beneficial ingredients, it does not actually make much practical sense.
So, how to choose tea? The main ones are twofold:
1. You think it tastes good;
2. You can afford it.
As for the other recommendations, just take a look at it, you don't have to take it seriously.
