A recent study published in Molecular Food and Nutrition Research demonstrated that a unique Arabica coffee, formulated with roasted and unroasted coffee beans, significantly increased the antioxidant status of healthy males.  Thirty three males, with bodyweight profiles ranging from healthy to overweight, were recruited for the study.  For the first 12 weeks (phase 1), subjects were instructed to refrain from coffee intake, and consumed three cups of hot water in the morning, at noon and in the afternoon for four weeks.  For the following four weeks (phase 2), volunteers replaced the hot water with the antioxidant-rich coffee blend (29.5 g 3x/day in 250 ml water).  Following the coffee consumption phase, subjects reverted back the phase 1 protocol and refrained from ingesting coffee for another four weeks.  Results demonstrated that the coffee blend significantly reduced biomarkers of DNA damage and enhanced the active form levels of circulating glutathione, a powerful endogenous antioxidant.  Finally, coffee consumption was shown to decrease body weight via a reduction in body fat.  This study lends further insight into potential health benefits when coffees that are formulated to contain bioactive compounds are combined with moderate coffee consumption.
