Green Tea and Black Tea Metabolite Concentration Determination through Proton Nuclear Magnetic Resonance

Abstract

Tea has been studied for many years with new findings on their effects on health. While tea still has some unknown effects on the human metabolism, this study aims to determine the effects of green tea and black tea consumption on the human metabolism through metabonomics. Urine samples were studied through proton nuclear magnetic resonance to determine the concentration of metabolites excreted. Subjects who consumed green tea showed a higher concentration of energy metabolites excreted than those who consumed black tea or caffeine alone. This suggests that green tea has a greater positive impact on the human metabolism. As the human metabolism begins to slow down due to aging, daily consumption of green tea may help to combat a slow metabolism.
