Abstract
Nutraceuticals or functional foods are foods that provide both health benefits to reduce the risk of chronic diseases and basic nutrition. Examples of nutraceuticals are natural foods, including antioxidants, dietary supplements, fortified dairy products, and citrus fruits, and vitamins, minerals, herbals, milk, and cereals. To enhance the efficacy of nutraceuticals, delivery systems are greatly needed to protect nutraceuticals from the harsh conditions of the gastrointestinal (GI) tract. Drug delivery systems using nanotechnology, such as biocompatible polymers, hold promise for the field of pharmaceutical science, as they offer tools and nanostructured materials that deliver therapeutic drugs for treating diseases successfully. Like drug delivery systems, several delivery systems have been designed for nutraceutical delivery, including smart polymers that are stimuli responsive. This chapter will mostly focus on the characteristics of nutraceuticals and discuss strategic designs of nutraceutical delivery systems.
