Sugary bottled teas strip out antioxidants, health benefits

A presentation at the American Chemical Society's national meeting indicates that bottled teas contain less of the chemicals that give tea its health benefits when compared to home-brewed teas. It should be no surprise that mass-market, mass produced teas are less healthy—the amount of added sugar and unneeded calories ensures that. But Professor Chi-Tang Ho and Dr. Shiming Li, found that the concentration of polyphenols—antioxidants commonly found in teas—was virtually non-existent.
