Abstract
Despite the inconclusive and largely inconsistent reports on the role of antioxidants (ANT) in human health, the multidimensional research approach in this discipline has provided significant evidence for their health benefits. Within the emerging functional healthcare paradigm, research on dietary antioxidant agents has taken center stage in the fight against oxidative damage. Several, mostly plant-derived food sources have been qualitatively and quantitatively assessed as antioxidant agents and for antioxidant activities. In advancing this research dimension, a number of in vitro methods for evaluating the free radical scavenging capacities of ANT agents have evolved concurrently, some of which are more advanced than others. Through these research advancements together with a few successful in vivo studies, dietary supplementation has been formulated for some food stuffs. However, one of the greatest challenges in this field is the applicability of the mechanistic results to human intervention models. Current and future research focus should center on addressing these challenges if the full antioxidant benefits to humans are to be realized.
