Fig. 7. Estimated antioxidant intake required (mmol/day) to prevent postprandial oxidative stress relative to energy intake (kcal). Relationship calculated as follows: Y = ((EI * DAUC)/MAUC) * IENU = ((EI*0.99/57)*0.25 = EI * 0.00461 where: Y = Antioxidant intake (mmol TE/day based upon ORAC_FL); EI = Energy Intake, kcal; MAUC = Mean Area Under Curve (µmol TE/L · h) per dose of fruit or berry in mmol Trolox Equivalents (TE) for 13 different foods tested in 6 clinical trials; DAUC = Decline in plasma AUC per kcal energy consumed in the absence of dietary antioxidants (0.99 µmol TE/L · h); and IENU = Inefficiency in utilization of dietary energy (Assumed to be 25%) [37].
