Moreover, this study is … The catechins found in white tea had shown to lower cholesterol levels, decrease blood pressure, and improve the functioning of the blood vessels, thereby eventually lowering the risk of cardiovascular disease . How much EGCG there is in white tea is about 40% less than green tea, though it’s still over 400% higher than black. Green tea is manufactured from fresh, unfermented tea leaves; the oxidation of catechins is minimal, and hence they are able to serve as antioxidants. The results suggest certain green and white tea types have comparable levels of catechins with potential health promoting qualities. Korean fermented tea which has lower amounts of catechins but a higher anti-oxidant capacity. Researchers believe that catechin is effective because it easily sticks to proteins, blocking bacteria from adhering … Catechin / ˈ k æ t ɪ tʃ ɪ n / is a flavan-3-ol, a type of natural phenol and antioxidant.It is a plant secondary metabolite.It belongs to the group of flavan-3-ols (or simply flavanols), part of the chemical family of flavonoids.. Teas Vary Considerably in EGCG Content Some people believe that teas can be graded according to their EGCG content, and that one “color” of tea contains more catechins than another. Catechin - Catechin is a tannin peculiar to green tea because the black tea fermentation process reduces catechins in black tea. A broad range of studies has examined EGCG to see if it may have any beneficial biological effects in humans, particularly concerning its potential impact on metabolism. They are present in nearly all teas made from Camellia sinensis, including white tea, green tea, black tea … A catechin molecule Mistaken as tannins previously, tea catechins are a group of phytochemicals existing naturally in the leaves of the tea plant, Camellia sinensis. Certain white teas have comparable quantities of total catechins to some green teas, but lesser antioxidant capacity, suggesting that white teas have fewer non-catechin antioxidants present. Several thousand types are available in the plant world. Specifically, the polyphenolic content of green teas was found to be similar to certain white tea varieties, which makes the latter tea type a potential substitute for people interested in consuming polyphenols for health reasons. Digestive tract uptake (bioavailability) of green tea catechins is low, ranging from 1.68% in humans (comparable in rats to approximately 13-26.5% in mice. White tea is made similarly to green tea; however, only the buds and young leaves of the tea plant are used. They are vital in the health contributive nature of tea.
