What are the differences in the health effects of different kinds of tea?

Tea is generally divided into green tea, black tea, oolong tea, white tea, yellow tea, black tea six categories, they have certain differences in health care effects, as follows:
Green tea
Outstanding antioxidant capacity: green tea is unfermented, retains a large number of natural ingredients, its tea polyphenol content is high, antioxidant capacity is relatively strong in all kinds of tea, help to clear free radicals in the body, prevent aging and some chronic diseases.
Strong antibacterial and anti-inflammatory effect: rich tea polyphenols have a significant inhibitory effect on a variety of bacteria, which can help prevent and reduce some inflammation, such as oral inflammation and gastrointestinal inflammation. At the same time, it has a good effect in preventing dental caries, because it contains fluorine and tea polyphenols can effectively inhibit oral bacteria and enhance the acid resistance of teeth.
Helps to reduce fat and lose weight: It can inhibit fat absorption and promote fat metabolism, which is more beneficial for people who want to control weight or prevent obesity-related diseases.
Black tea
Nourishing stomach and protecting stomach: Black tea is a fully fermented tea with mild tea properties. During the fermentation process, the content of tea polyphenols was reduced, and new components such as theaflavins and thearubinins were produced. These ingredients not only make black tea have a unique flavor, but also have a certain protective effect on the gastric mucosa, which is suitable for people with a more sensitive stomach.
Enhance immunity: theaflavins in black tea have antioxidant and antibacterial effects, which can help the human body resist the invasion of external pathogens and improve the body's immunity. In addition, the polysaccharides in black tea also help boost immune function.
Promote blood circulation: the caffeine and aromatic substances in black tea can promote blood circulation, accelerate metabolism, have certain benefits for cardiovascular health, especially suitable for drinking in cold weather, can help warm the body and drive away the cold.
Oolong tea
Decomposition of fat: between green tea and black tea, Oolong tea belongs to semi-fermented tea, which contains unique ingredients, such as tannic acid, etc., has a good function of decomposition of fat, can reduce the content of cholesterol in the blood, and has a certain effect on weight loss and prevention of cardiovascular disease.
Oolong tea has a high caffeine content, which can excite the central nervous system, play a refreshing role, and help improve work efficiency and attention. At the same time, it can also promote the secretion of gastric juice, enhance digestive function, and help the digestion and absorption of food.
Aging prevention: Although the degree of fermentation of oolong tea is moderate, it is still rich in antioxidant substances such as tea polyphenols, which can remove free radicals, delay cell aging, and keep the body young.
White tea
Reducing heat and fire: White tea is not rolled and killed in the production process, retains more natural ingredients, has the effect of reducing heat and reducing fire, suitable for drinking in hot weather or when the fire. Its rich flavonoid compounds have strong antioxidant and anti-inflammatory effects, helping to ease the body's inflammatory response.
Cardiovascular protection: Components such as tea polyphenols and theanine in white tea can reduce blood cholesterol and triglyceride content, inhibit platelet aggregation, reduce the risk of thrombosis, and have a certain protective effect on the cardiovascular system.
Enhance immunity: The polysaccharide substances in white tea have an immune regulatory effect, which can enhance the body's immunity and improve the body's ability to resist disease.
Yellow tea
Digestive aid: Yellow tea is dull yellow in the processing process, forming a unique quality and composition. Its rich tea polyphenols, caffeine and other components can promote the secretion of gastric juice, enhance gastrointestinal peristalsis, help digestion and absorption, and have a certain improvement effect on dyspepsia, loss of appetite and other problems.
Antioxidant: Although the degree of fermentation of yellow tea is light, it still contains a certain amount of antioxidant substances such as tea polyphenols, which can clear free radicals in the body, reduce oxidative damage, and delay aging. At the same time, these antioxidants also have a certain positive significance in the prevention of chronic diseases such as cardiovascular disease and cancer.
Dark tea
Regulation of intestinal flora: Black tea is a post-fermented tea, which produces a wealth of beneficial microorganisms and metabolites during the fermentation process, such as probiotics and oxidation products of tea polyphenols. These ingredients can regulate the balance of intestinal flora, promote intestinal motility, improve intestinal function, and prevent constipation and intestinal diseases.
Reducing blood lipids: The tea polysaccharides and tea polyphenols in black tea can reduce the content of cholesterol, triglycerides and low density lipoprotein cholesterol in the blood, while increasing the content of high density lipoprotein cholesterol, which has a significant effect on regulating blood lipids and helps to prevent cardiovascular diseases.
Supplementary nutrition: Black tea contains rich vitamins and minerals and other nutrients, such as B vitamins, vitamin E, potassium, calcium, magnesium, etc., can supplement the necessary nutrients for the human body.
