What are the advantages of tea polyphenols?
Tea polyphenols are natural phenol compounds found in several varieties of tea, which are also commonly referred to as flavonoids. One of the reasons why these compounds are often mentioned as beneficial as tea polyphenols is that they are highly concentrated in tea products. The main category among flavonoids found in tea is known as catechins and green tea has a higher concentration than any other type of tea. Flavonoids serve as antioxidants and protect the body from damage to free radicals that can lead to cancer, and are concentrated in ten times the level of green tea polyphenol and black tea polyphenols compared to antioxidant levels found in fruits and vegetables. This applies to green tea, black tea and oolong tea that are all derived from sinensis. Both black and oolong tea are fermented, while green tea leaves are steamed, leading to different flavors. The main beneficial antioxidants in these three typesEech teas are overall catechins, epicatechins and theaubigins. Other types of tea polyphenols also exist in various tea flavors, including herbal teas, but medical research of the benefits of these other varieties has not been so extensive since 2011.
In addition to the merger of cell protection from damage caused by the molecules of free radical oxygen in the bloodstream, it has been shown that tea polyphenols also have other health benefits. These include prevention of DNA damage caused by cigarette smoke or other use of tobacco, as well as blocking the harmful effects of other toxic chemicals that enter the bloodstream. The incidence of heart disease is statistically reduced in nations, such as China and Japan versus the level of occurrence in Western countries. The tradition of consuming a large amount of green and black tea in these countries has led to a decreased heart disease can be partially attributed to tea polyphenOLY. Population studies have also shown a reduced level of diabetes in countries where the standard is high tea consumption.
other tea polyphenols are also found in many natural teas such as Kaempferol and Quercetin, but concentrations are lower and extensive research has not been carried out to their advantages. The 2006 Japan and Taiwan Study also found that drinking a cup of green or oolong tea with a high fat diet significantly reduced the level of bad cholesterol. The evidence further suggests that the regular consumption of these teas could lead to weight loss and could also delay the advent of Alzheimer's disease.
