Dietary Polyphenols by Francisco A . Tomás-Barberán,Antonio González-Sarrías,Rocío García-Villalba Pdf

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.

Dietary Polyphenols and Human Health by Anna Tresserra-Rimbau Pdf

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.

Polyphenols and the Mediterranean Diet by Manel Issaoui,Amélia Martins Delgado,Candela Iommi,Nadia Chammem Pdf

This book focuses on polyphenols in the Mediterranean diet, providing a detailed overview of their chemical structure, extraction and analysis methods, and their role in the diet and in flavor. Phenols are important not only in terms of preventing a number of diseases due to their antimicrobial and antioxidant effects, but also in shaping our perception of foods. The first chapter discusses consumers’ sensory assessment of foods containing polyphenols in terms of flavor and color, as well as the chemical properties and natural sources of phenolic compounds. The second chapter examines hygiene and safety claims with respect to naturally occurring polyphenols, especially in connection with organoleptic features. The third and final chapter examines the dietary sources of these molecules from various fruits, including processed products such as infusions, wines, oils and olives. Given its scope, this book is a valuable resource for researchers in academia and industry interested in food safety, hygiene and production issues related to the Mediterranean diet.

Application of Polyphenols in Foods and Food Models by Anonim Pdf

Phenolic compounds are secondary metabolites found in legumes, grains, fruits, algae, leaves and many other dietary sources. However, the abundance and differences in chemical structure, solubility, toxicological safety and, therefore, bioactivity and functional effects in humans. This book covers the basic chemical composition and structure of phenolic compounds and focus on their technological applications in food models and products: nondairy and dairy beverages, bakery, and meat-based foods. Additionally, food preservation aspects, including the effects of polyphenols additions on the product’s shelf-life, processing and recovery of polyphenols from plant materials, antioxidant and antiproliferative aspects of polyphenol-rich extracts are considered and holistically debated. Toxicological safety of polyphenols in foods is explained and discussed Application of polyphenols in dairy and nondairy foods is discussed Effects of polyphenols on food preservation/shelf-life are explained
