Food products industry generates many undesired waste materials. Proper use of these by-products may minimize problems with waste disposal and act as a possible new source of fats and proteins for food and feed use. Peels, and seeds resulted from fruit and vegetable manufacturing are effectively utilized as a promising source of many phytochemicals and antioxidant agents. The produced by-products are an important and vital source of many carbohydrates, minerals, organic acids, dietary fibers and phenolic compounds that have a broad spectrum of antiviral, anticancer, antimicrobial, and cardioprotective action. Hence, there is poor available information about the beneficial values and use of theses by-products, this review article is concerned about the variety of the biological activities could be exerted by these remarkable secondary metabolite rich sources.

This review represents a scientific approach regarding the utilization of phytochemicals in research work field as promising radioprotective agents. Recently, numerous studies proved the efficacy of phytochemicals as antioxidant, antimicrobial, anti-inflammatory and anticancer. Consequently, based on the previous exerted activities, phytochemicals have drawn the attention as radioprotective agents in both prophylactic and post radiation treatment protocols. Moreover, this collective work is basically concerning about the radiation meaning, types, effect on human health and offers a new perspective scenario about the outstanding benefits of phytochemicals, found in many plants around us and their unique radioprotective effect.
