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. Topics include structural diversity of polyphenols and distribution in foods, bioavailability and bioaccessibility of phenolics, metabolism, and gastrointestinal absorption of various metabolites and their health effects. This comprehensive volume: Discusses the bioavailability, bioaccessibility, pharmacokinetics studies, and microbial metabolism of different groups of phenolic compounds Examines the interaction between polyphenols and gut microbiota Describes analytical methods for identifying and quantifying polyphenols in foods and biological samples Reviews recent epidemiological and clinical intervention studies showing protective effects of polyphenols Dietary Polyphenols: Metabolism and Health Effects is an important resource for scientists working in the area of dietary polyphenols and health effects, microbiota, and their interaction with other nutritional compounds, and for health professionals, nutritionists, dieticians, and clinical researchers with interest in the role of polyphenols in the prevention and treatment of chronic diseases.

Polyphenols are a heterogeneous group of bioactive compounds mainly found in plant-based foods. Numerous clinical and epidemiological studies have led to the result that polyphenol intake may protect against chronic diseases such as cardiovascular and neurodegenerative diseases, cancer, or type 2 diabetes, to name some. Polyphenol intake estimation can be obtained through food frequency questionnaires and nutritional biomarkers, both having their own advantages and disadvantages. Although the association between these bioactive compounds and health seems irrefutable, many questions remain still unanswered. For instance, more studies are needed to identify possible interactions and effect-modulating variables, such as smoking habit, body mass index, sex, alcohol, hormones, other foods, etc. Moreover, intestinal microbiota seems to play an important role in the metabolism of polyphenols, but it is still unclear how.

"Bio-Farms for Nutraceuticals" can be said to have been born of the NUTRA-SNACKS project within the Sixth Framework Programme Priority on Food Quality and Safety. One objective of NUTRA -SNACK S was to improve the nutritional and eating properties of ready-to-eat products and semi-prepared foodstuffs through better monitoring of the quality and safety of raw materials and the development of innovative processes along the production chain. Another main objective of the project was the production of ready-to-eat snacks with high nutraceutic activity. Seven research institutes and three companies in six European countries were involved in this effort. The co-operation resulted in the production of food having a high content of natural metabolites with the following beneficial health effects: anticancer, antilipidemic, anticholesterol, antimicrobial, antibacterial, antifungal, antiviral, antihypertensive, anti-inflamatory and antioxidant activities.
