The human body is constantly exposed to so-called free radicals, which are a burden on the body. If they get out of hand, the result is oxidative stress, which can promote disease. While this has been treated in the past with the help of antioxidant vitamins and minerals, scientists are now increasingly turning to the use of phytochemicals, representing plant secondary metabolites. This has resulted in an analysis of almost 300,000 scientific papers by a team led by the molecular biologist Atanas G. Atanasov from the University of Vienna. The results have recently been published in the journal Oxidative Medicine and Cellular Longevity.
