Aronia contains significant amounts of polyphenols, which are a group of antioxidants that include phenolic acids, anthocyanin and flavanols. A study conducted on 30 healthy people who consumed chokeberry resulted in a significant reduction, within 24 hours, of oxidative stress caused by an antipsychotic drug. Numerous studies on the effects of aronia on human health have resulted in impressive health effects, such as: protection from inflammations and fighting bacterial and cancer cells.
