In vitro and in vivo antioxidant activities of cereal grains are summarized.
Cereals provide significant levels of bioactive phytochemicals including phenolic acids and carotenoids.
These phytochemicals are unevenly distributed in the grain kernel and possess antioxidant properties.
Consumption of cereal grain products favorably alters endogenous antioxidant markers.
Adequate intake of cereal grains may potentially mitigate oxidative stress.
