With the soaring temperatures it is not surprising to spot chilled bottled beverages being chugged down in profuse quantities. For the health fanatics, several of these drinks have or are made from green tea which has an indisputable reputation of proffering myriad health benefits. Green tea is touted to help reduce the risk for wide-ranging ailments caused either by bacteria or virus, unceasing de-generative health problems like heart ailment, cancers, stroke, RA (rheumatoid arthritis), diabetes among many others. However, beverage consumers need to understand a vital point that green tea preparation is not the same in every case and the key lies in the manner that it has been brewed.
Green tea is the one which has undergone the least extent of processing as compared to all other forms of tea. Its preparation process initially involves the lately reaped leaves being steamed for a short time which renders them soft-textured and pliant and prevents them from undergoing fermentation or transforming color. Once steamed the rolling and spreading out of these leaves are done that are then left out for drying in tepid air. Since green tea has been minimally processed hence the antioxidants (catechins) that are deemed to avert oxidation-caused harm are thus in greater concentration.
Promotion of several of the bottled forms of green tea is done with claims of antioxidant presence merely because of the existence of green tea. However the form of green tea/ green tea extract which is employed in several of these brands is in fact considerably lesser than even a cupful of good old green tea post-brewing. Factually a trial conducted by scientists Chi-Tang Ho & Shiming Li noted that in several scenarios an individual would need to consume nearly twenty-fold the quantity of bottled green tea during a day for reaping the analogous health gains as that found in a cupful of brewed green tea.
Elucidating the finer points of their study during a congregation of the American Chemical Society, the investigators concluded that a number of reputed brand names making bottled green tea have notably lesser polyphenol presence as compared to black/green tea post-brewing. Majority of the brand names that the researchers examined had practically zilch antioxidant presence whereas many other brands have miniscule quantities which failed to provide any notable benefits to health.
Largely the bottled versions of green teas additionally have been artificially sweetened and have non-advantageous constituents that could annul any gains which were professed initially.
