The role of omega-3 fatty acids in health has been well established, and new research helps explain the association. In a recent study, mice given fish oil containing high amounts of omega-3 fatty acids (especially DHA) demonstrated the activation of several cellular “protections:” (1) the activity of protective enzymes in the liver and heart tissue increased significantly; (2) oxidative stress (as measured by F2-isoprostanes) and damage to sensitive brain tissue (cerebral lipid peroxidation) were dramatically decreased; (3) telomere shortening in the liver and testes was reduced; and (4) DHA helped prevent the expression of cancer-causing genes. Researchers suggest communication that links oxidative stress, telomeres, and cancer genes into what they call a “redox-telomere-antioncogene axis.”
