Does drinking green tea have any side effects? Unlike black tea, green tea is not fermented, so retains polyphenols, such as flavanols, of which catechins are particularly important. Catechins are ...
[10] [11] Tea has one of the highest contents of flavonoids among common food and beverage products. [7] Catechins are the largest type of flavonoids in growing tea leaves. [6] According to a report released by USDA, in a 200-ml cup of tea, the mean total content of flavonoids is 266.68 mg for green tea, and 233.12 mg for black tea. [7]
It is found in high content in the dried leaves of green tea (7380 mg per 100 g), white tea (4245 mg per 100 g), and in smaller quantities, black tea (936 mg per 100 g). [2] During black tea production, the catechins are mostly converted to theaflavins and thearubigins via polyphenol oxidases .
I discovered that green tea is chock-full of polyphenols—especially catechins—which are "powerful antioxidants," according to Goodson. "Antioxidants help neutralize free radicals in the body ...
This is thanks to its high levels of natural compounds called polyphenols, such as catechins and flavonoids. For example, green tea contains a particularly powerful compound called ...
Epicatechin gallate (ECG) is a flavan-3-ol, a type of flavonoid, present in green tea. [1] It is also reported in buckwheat [2] and in grape. [3]The tea component epicatechin gallate is being researched because in vitro experiments showed it can reverse methicillin resistance in bacteria such as Staphylococcus aureus. [1]
