But do you know what ingredients in tea play a beneficial role in body and mind? Today, let's talk about the treasure of tea-tea polyphenols.
Name: Tea Polyphenols
Definition: The general term for polyphenols in tea.
Contains flavanols, anthocyanins, flavonoids, flavonols and phenolic acids.
Important content: flavanols (catechins), accounting for about 70% of the total tea polyphenols.
Characteristics: It is one of the main components that form the color, fragrance and health care function of tea.
Not all teas have the same content of tea polyphenols.
The deeper the tea is fermented, the more tea polyphenols are converted into other substances, and the content of tea polyphenols will decrease accordingly.
While green tea is not fermented, the content of tea polyphenols is quite rich. According to statistics, the content of tea polyphenols in green tea is144% higher than that of black tea with the same quality and about 59% higher than that of oolong tea with the same quality.
In addition to the types, the quality of tea will also affect the content of tea polyphenols.
For example, when making tea, the tender the tea, the better the quality. Because the young leaves grow at the top and are closest to the sun, they can fully carry out photosynthesis and synthesize more phenolic substances.
? No. 1 anti-aging
Tea polyphenols have strong antioxidant and physiological activity, and are scavengers of human free radicals, which can inhibit lipoxygenase and lipid peroxidation in skin mitochondria, thus having anti-aging effect.
Studies have shown that 1 mg tea polyphenols have the same scavenging effect on excessive free radicals harmful to human body as 9 micrograms of superoxide dismutase (SOD), which is much higher than other similar substances.
The antioxidant activity of tea polyphenols is obviously stronger than that of vitamin E 18 times, and it has synergistic effect with vitamins C and E. Many cosmetics are added with tea, which makes use of the anti-aging effect of tea polyphenols.
? No.2 alleviates allergies
Polyphenols can strongly inhibit the release of histamine. Experiments show that the anti-allergic and anti-allergic effects of tea polyphenols are 2~ 10 times stronger than those of commonly used anti-allergic drugs at present, but tea can not be directly used as medicine for anti-allergy.
no.3? expel toxin
Tea polyphenols have a strong adsorption effect on heavy metals, and can form complexes with heavy metals to produce precipitates, which is conducive to reducing the toxic effects of heavy metals on human bodies.
Tea polyphenols can also improve liver function and diuresis, so it has a good anti-lysis effect on alkaloid poisoning.
no.4? aid digestion
Caffeine in tea polyphenols can increase the secretion of gastric juice, help digestion and enhance the ability to decompose fat. The so-called "long-term eating makes people thin" is here.
No.5 radiation protection
Tea polyphenols and its oxidation products have excellent anti-radiation function, which can absorb radioactive substances and prevent them from spreading in the human body. They are called natural ultraviolet filters.
? No.6 tooth protection
Tea polyphenols can kill lactic acid bacteria and other dental caries bacteria in the teeth, inhibit the activity of glucose polymerase, and effectively interrupt the process of dental caries formation.
Protein food left in the teeth becomes the matrix for the proliferation of putrefying bacteria, and tea polyphenols can kill such bacteria.
No.7 beauty
Tea polyphenols are water-soluble substances, which can remove greasy face and astringe pores, and have the effects of disinfection, sterilization, anti-aging and reducing the damage of ultraviolet radiation to the skin in sunlight.
However, the girls who love beauty should pay attention to whether they will be allergic before washing their faces directly with tea, and the effect will vary from person to person.
? No. 1 hypertension
Tea polyphenols have a strong inhibitory effect on invertase activity, so they can reduce or keep blood pressure stable.
no.2? thrombus
Tea polyphenols can protect and repair erythrocyte deformability, and it is easy to form a complex with thrombin to prevent fibrinogen from becoming fibrin.
Tea polyphenols can effectively inhibit the increase of cholesterol content in plasma and liver, and promote the excretion of lipids and bile acids, thus effectively preventing the formation of thrombosis.
?
no.3? asthma
Tea polyphenols can inhibit allergic reactions caused by active factors such as antibodies, adrenaline and enzymes, and have a significant effect on allergic diseases such as asthma.
? No.4 constipation
As the saying goes, "a cup of tea in the morning is a prestige one day", and tea polyphenols can stimulate gastrointestinal reaction and accelerate the peristalsis of large intestine to achieve the effect of treating constipation.
No.5 diarrhea
Tea polyphenols can inhibit and kill all kinds of harmful pathogens that cause diarrhea by improving the comprehensive immune ability of human body, and relieve the tension of stomach and intestines, so as to achieve the effect of diminishing inflammation and stopping diarrhea.
No.6 scurvy
Tea polyphenols can promote the absorption of vitamin C, thus effectively preventing and treating septicemia.
Drinking tea makes people healthy, largely thanks to the role of tea polyphenols.
Although tea polyphenols have rich effects.
But tea is not medicine!
Can't directly replace drugs! !
Related diseases have to follow the doctor's advice to take drugs! ! !
In daily life, drink more tea, keep healthy, have many benefits, and live a healthy life, starting with a cup of tea ~
