Public opinion has been recently subjected to campaigns about the efficacy of dietary supplements in the prevention of cancer and cardiovascular diseases (folic acid, antioxidants, calcium and Vitamin D). Italy proves to be the first consumer of dietary supplements in Europe. The scientific evidence is not univocal and the assumption of food containing the active ingredients (vegetables in particular) has proved more effective as preventive measure than supplements containing them. It is therefore desirable a more cautious use of food supplements and only in order to provide for documented deficiencies, also considering their negative side effects in case of overdose.
