An Overview on Natural Antioxidants Derived from Food Sources

As per recent reports, our human cellsbelong to aerobic environments are susceptible to damage from reactive oxygen metabolites (ROMs) that are effectively neutralized by the robust antioxidant system present in the human body. Antioxidants are chemicals that exhibit the ability to postpone or reduce oxidative damage to a specific molecule. Antioxidants are abundantly present in natural sources such as plants, food materials, etc. Several such sources of antioxidants include Vitamin E, Vitamin C, carotenoids, glutathione, and polyphenols (thymol, eugenol, vanillin, guaiacol, menthol, sesamol, and umbelliferon). In the present review article, it was thoroughly investigated for those antioxidants using for management of various human diseases. Recently, many efforts are being made by scientists to identify those antioxidants that may be proven as potential pharmaceutical agents for the treatment of various disorders. In this context, phenolic and polyphenolic substances have been commonly utilized for the said purposes. This article based on a literature survey describes many natural antioxidants that were utilized for anti-aging effects, immunity boosters, improving nerve function as well as preservatives in many cases.
