Presents recent research on metabolism and the health effects of polyphenols Consumer interest in the health benefits of many phenolic compounds found in plant foods and derivatives has grown considerably in recent years, giving rise to an increased demand for functional foods. Although preclinical and observational studies have promoted the protective properties of polyphenols for a range of chronic diseases, evidence has shown that most dietary polyphenols have little bioavailability. Once ingested, most of them are metabolized by either the intestinal enzymes or by the gut microbiota and then undergo extensive phase-II metabolism reaching significant concentrations of conjugated metabolites. They remain in the systemic circulation and target systemic tissues where trigger biological effects. The polyphenol-derived metabolites produced in humans are dependent upon the composition of the gut microbiota and the subject genetics. Thus all the metabolites do not show the same biological activity in different individuals. To fully understand the health effects of polyphenols, further clinical investigations are required. Dietary Polyphenols describes the latest findings on the polyphenol metabolism and reviews the current evidence on their health effects and that of their bioavailable metabolites. Emphasizing the importance of interindividual variability and the critical role of gut microbiota, this authoritative volume features contributions from recognized experts in the field, exploring specific families of extractable and non-extractable phenolic compounds that exhibit potential health effects.

Rice is a vitally important staple food for almost half of the world’s population. As the global population increases, the demands for rice are expected to remain high. Since the rice industry will remain sustainable for a long time, the production of rice by-products will remain high. Substantial evidence suggests that rice by-products such as rice husk, rice straw, broken rice, rice germ, rice bran, and brewers’ rice may possess beneficial effects against oxidative stress and metabolic disorders. These beneficial effects have been linked to the phytochemicals present in rice by-products such as vitamin E, dietary fiber, γ-oryzanol, γ-aminobutyric acid (GABA), and phytosterols. Despite this evidence, the literature pertaining to rice by-products and its derived components has not well been compiled. To this end, Rice By-products: Phytochemicals and Food Products Application provides full coverage of issues pertaining to rice by-products, namely rice demands and rice by-products production, phytonutrients and antioxidant properties of rice by-products, potential health benefits, application in food products, and future prospects.
