Various components of green tea and their effects on human body;
Health care function of green tea;
Green tea, through the research of scholars all over the world, has been proved to inhibit the transformation of food preservative nitrite into carcinogen in human body. The experimental results at the annual research report of Japan Radiation Research Association 199 1 found that green tea can inhibit the action of microsomal enzyme system and carcinogen, and will prevent the carcinogen process, which is of great benefit to cancer prevention. In addition, green tea has many health-care functions:
1, delaying aging:
Green tea contains a lot of catechins and antioxidant vitamins (β-carotene, vitamin E and vitamin C), so it can prevent cancer and avoid premature aging. Moreover, the antioxidant effect of green tea is 20 times stronger than that of vitamin E, which can reduce the production of active oxygen and effectively eliminate free radicals, which is quite helpful for preventing senile diseases.
2, refreshing:
Although the chemical structure of caffeine in green tea is the same as that of coffee, under the action of specific catechins, people who drink green tea will gradually regain their spirits, enhance their endurance and be awake, but the excitement of caffeine in green tea will slow down and last.
3, adjust the physiological function:
Green tea can help decompose fat, lower blood pressure, prevent and improve cardiovascular diseases, and inhibit the rise of blood sugar and the growth of pathogenic bacteria.
4. Eliminate Staphylococcus aureus
Applicable symptoms:
Diseases, fat reduction, enterovirus, common virus infection, bronchitis (eucalyptus plus green tea), cancer, hepatitis B (green tea and sandalwood).
Green tea has many functions, such as "anti-cancer", "inhibiting the rise of blood pressure", "inhibiting the rise of cholesterol", "anti-oxidation, and inhibiting aging. These functions are mainly derived from catechins. Besides catechins, green tea also contains many healthy ingredients, such as lycopene, vitamins C and E, etc. No matter what season, green tea can be a light dietary material, and drinking a cup of green tea at work can boost your body and mind. That's because caffeine in green tea has a refreshing effect. In a word, green tea has changed from a single hobby to a food with physiological regulation function, which has been gradually affirmed. Green tea has many benefits to human body. Yagedan green tea essential oil is the essence of extracting beneficial components from green tea. It is not easy to extract these essences. Only three kilograms of essential oil can be extracted from 100 kilograms of green tea, and then the fragrance is sweet and natural after being heated by incense. Green tea can prevent cancer, oxidation and cell pathological changes, and the interaction between plant essential oil and plant alcohol can double the effect.
Therefore, according to research, green tea can regulate physiological functions and help decompose fat. There are many ways to lose weight by using green tea in the market. Although it has not been scientifically proved, its efficacy has spread among the people, such as: green tea powder with yogurt, green tea powder with Yakult, green tea without sugar and so on. Because the alkaline substances in green tea can decompose body fat, the same feature of these methods circulating in the market is that they must drink a lot of green tea to achieve it. But in terms of plant essential oil, 100 kg of green tea can only extract 3 kg of pure plant essential oil, that is to say, it is better to order green tea essential oil than to drink one kg of green tea desperately, so that there will be no nausea caused by drinking a lot of green tea, and both internal and external environmental protection work can be taken into account at the same time.
Aromatic compounds in green tea can dissolve fat, remove turbidity and greasy, and prevent fat from accumulating in the body, while vitamins B 1, C and caffeine can promote gastric juice secretion and help digestion and fat elimination. Leaf soap can also add strength to your slimness. In addition, green tea can also increase the metabolism of body fluids, nutrition and calories, strengthen microvascular circulation and reduce fat deposition in the body?
[Correct brewing method of green tea]
● When brewing green tea, the water temperature should be controlled at about 80℃ ~ 90℃. If green tea powder is brewed, it can be brewed with warm water of about 40℃-60℃. The serving size is 2g of green tea powder and 450ml of boiled water.
● Don't drink the tea brewed for the first time. Shake it with hot water and pour it out.
● The brewed tea should be finished within 30 minutes to 60 minutes, otherwise the nutrients in the tea bag will become unstable.
● Green tea powder should not be soaked too thick, otherwise it will affect the secretion of gastric juice. It is best not to drink on an empty stomach.
The contents of antioxidant components in black tea and green tea are almost the same, but green tea is a natural component without fermentation, while black tea is completely fermented, which makes the structure of antioxidant components-flavonoids in tea slightly different. The limit of eating green tea is to finish it as soon as possible (about 30 minutes), and the best brewing temperature is 80 degrees Celsius. Excessive temperature will destroy the effective components in green tea and lose the benefits of drinking green tea. Some people think that slightly bitter green tea is cool and suitable for drinking in summer. Black tea contains more caffeine, which is more refreshing and diuretic than green tea. Generally, black tea contains less tea polyphenols. For people with weak spleen and stomach and stomach problems, the taste is mild and less "disturbing the stomach". The slightly bitter and sweet black tea is hot and suitable for winter use.
In the process of making tea leaves, when the tea leaves come into contact with air, they are fermented and oxidized, which makes the green tea leaves turn red slowly. The degree of reddening determines the degree of fermentation.
