Cereals have potential role in human health due to their high amounts of antioxidant compounds especially in insoluble bound forms. Bound antioxidants are crucial for living organisms as they exert their antioxidant effects much longer than soluble antioxidants. They reach the colon without being digested through the small intestine and contribute to the formation of reduced environment in the colon, while soluble antioxidants ingested with diet cause a rapid and short-term increase in plasma antioxidant capacity upon absorption in the small intestine. From this point of view, cereal dietary fiber-antioxidant compounds complexes have come into prominence in recent years and researches have focused on their health benefits, digestion behavior and bioavailability in gastrointestinal system and determination of their antioxidant capacity both in vivo and in vitro. This review aimed to collect important knowledge related to cereal antioxidant compounds and give a general perspective on their potential antioxidant effects.
