The accumulation of free radicals plays a well-documented role in the pathogenesis of many chronic diseases. Antioxidants are the agents that are capable to react with free radicals, neutralize their reactive potential by quenching, and thus reduce the ability of free radicals to damage DNA and other cellular structures.
Antioxidants are responsible for maintenance of oxidative balance of the cells. In order to maintain health, it is useful to ensure efficient intake of specific antioxidants from food.
The authors present and highlight the selected food groups and beverages with high antioxidant values, their health benefits and the effect of processing on the bioavailability of these nutrients.
