Antioxidant/Oxidant Balance as a novel approach to evaluate the effect on serum of long-term intake of plant antioxidant-rich foods

Serum Antioxidant/Oxidant Balance (AOB), calculated as Antioxidant Capacity (AC)/Peroxide Level (PxL) ratio, was applied for the first time to two long-term small pilot studies: a three-week and eight-week investigations, regarding the intake of 250 g/day cherry puree and a diet including several fo...
