ABSTRACT
Nutraceuticals have enormous chances for growth and expansion in terms of health benefits, as they are biologically active molecules found in foods that may not be essential for maintaining normal human functions, but may enhance human health and well-being by inhibiting certain diseases or improving human performance. The delivery of nutraceuticals using foods may decrease the risk of certain types of chronic diseases, including cancer. Nutraceutical-rich bioactive dietary components have the ability to prevent cancer. McClements and coworkers proposed a new classification scheme known as nutraceutical bioavailability classification scheme to characterize the main factors limiting the oral availability of nutraceuticals in food matrices. Nanoformulations of nutraceuticals provide many advantages over conventional formulations and consequently allow their clinical use for protection and treatment of different tumors. There is growing interest in using specific nutraceuticals commonly found in foods as chemopreventative agents.
