[Excerpt] The biological concept of antioxidant refers to any compound that is able to delay or 5 prevent the oxidation of easily oxidizable substrates, such as DNA, proteins and 6 lipids. Antioxidants reduce oxidative stress and mutations in DNA as well as other 7 parameters associated with cell damage. Epidemiological studies have proven the 8 ability of antioxidants to contain the effects of reactive oxygen species (ROS) and of 9 reactive nitrogen species (RNS) activities and decrease the incidence of cancer, as 10 well as other degenerative diseases (Morales-Gonzalez 2013).
