Bioactive peptides from fish by-products with anticarcinogenic potential

As a major cause of death, cancer has affected the world population, both directly and indirectly. There are however, growing numbers of cancer cases some of which could be prevented or even treated using natural compounds. Bioactive peptides from terrestrial and marine environment have been claimed to potentially reduce the risk of chronic diseases or maintain health. Fish processing industry produces more than 50% by-products which can be converted into valuable fish protein hydrolysate (FPH) by chemical or biochemical hydrolysis. This paper discusses the potency of fish by-products as sources of bioactive peptides with anticarcinogenic potential. Moreover, a short review about the antioxidant and anticancer activities of novel bioactive peptides isolated from fish by-products is presented.
