The use of antioxidants in sports is controversial due to existing evidence that they both support and hinder athletic performance. Antioxidants in Sport Nutrition covers antioxidant use in the athlete ́s basic nutrition and discusses the controversies surrounding the usefulness of antioxidant supplementation. The book also stresses how antioxidants may affect immunity, health, and exercise performance. The book contains scientifically based chapters explaining the basic mechanisms of exercise-induced oxidative damage. Also covered are methodological approaches to assess the effectiveness of antioxidant treatment. Biomarkers are discussed as a method to estimate the bioefficacy of dietary/supplemental antioxidants in sports. This book is useful for sport nutrition scientists, physicians, exercise physiologists, product developers, sport practitioners, coaches, top athletes, and recreational athletes. In it, they will find objective information and practical guidance.

It reveals the bioantimutagenic potency of epigallocatechin gallate (EGCg) found in green tea.

The global popularity of herbal supplements and the promise they hold in treating various disease states has caused an unprecedented interest in understanding the molecular basis of the biological activity of traditional remedies. Herbal Medicine: Biomolecular and Clinical Aspects focuses on presenting current scientific evidence of biomolecular ef

While there is a nearly universal agreement that drinking tea can benefit health, information on the benefits or adverse effects of drinking tea is scattered, leaving definitive answers difficult to ascertain. Tea in Health and Disease Prevention, Second Edition, once again addresses this problem, bringing together all the latest and most relevant information on tea and its health effects into one comprehensive resource. This book covers compounds in black, green, and white teas and explores their health implications, first more generally, then in terms of specific organ systems and diseases. With over 75% brand new content, this fully reorganized, updated edition covers a wider range of tea varieties and beneficial compounds found in tea, such as epigallocatechin gallate and antioxidants.Tea in Health and Disease Prevention, Second Edition, is an organized, efficient resource that will help readers find quick answers to questions and will help inspire further studies for those interested in tea research. This is a must-have reference for researchers in food science and nutrition, as well as nutritionists and dieticians. - Covers and compares features, benefits, and potential negative effects of the most important types of tea, including green, black, and white - Identifies therapeutic benefits of teas for new product development - Offers a "one stop shop" for research in this area, compiling both foundational and cutting-edge topics into one resource - Includes a dictionary of key terms, other health effects of tea or extracts, and a summary point section within each chapter for a quick reference

Derived from leaves of evergreen herb Camellia sinensis, green tea is known for its significant human health benefits. Once primarily consumed in Asia and North Africa, green tea is becoming increasingly available around the world with an increase in its average annual growth. There has been a tremendous change in the consumption pattern of green tea, a prime drive of which is the increasing knowledge about and marketing of its health benefits. The most notable health benefit of green tea is its powerful antioxidant potential, which helps prevent cellular damage from certain oxidation reactions in the body at the molecular level. Green tea is attributed to health claims which include the prevention of skin cancer, lower blood pressure, the prevention of cardiovascular diseases, neurodegenerative and kidney disorders, diabetes, respiratory distress, the inhibition of clinical and opportunistic microbial infections, and many more. The rich presence of polyphenols in green tea is likely responsible for its multiple health benefits. in vitro and in vivo epidemiological evidence suggests the importance of green tea polyphenols in exerting antioxidant activities which confer medicinal and food value. Major polyphenols found in green tea include the catechins, such as epigallocatechin gallate, epigallocatechin, epicatechin 3- gallate, epicatechin, and catechin gallate. These catechins have shown promise in the promotion of cardiovascular health, the prevention of cancer, skin protection, the reduction of high cholesterol levels, diabetes, impaired immune function, diarrhoea, fatigue and infection. There is a highly significant relationship between phenolics, flavonoids and the antioxidant activity of green tea, while the amount of phenolic, flavonoids and antioxidants are the parameters depicting the quality of tea according to their biological properties. This book is an informative forum highlighting research on the antioxidant activity of green tea pertaining to its health benefits. The book is organised into seven chapters that provide a comprehensive review of the antioxidant activity of green tea and its associated health benefits. The book outlines useful information and improves the fundamental knowledge regarding the processing of green tea, its chemical components, their role as antioxidants and usefulness as nutraceuticals.

There is a wealth of published research on the health-promoting effects of green tea and its various components including polyphenols. Green Tea Polyphenols: Nutraceuticals of Modern Life presents a collection of global findings on the numerous health benefits of green tea polyphenols, confirming their position as healthy functional ingredients. With chapters contributed by experts in the field of green tea science and the inclusion of extensive references, this book provides an authoritative volume that can be used to guide researchers, scientists, and regulatory bodies. Each chapter previews a specific theme and highlights recent research and development conducted in the field. The book begins with the history, processing, and features of green tea. It then describes the chemical composition and biochemical and physicochemical characteristics, followed by a discussion of the properties of green tea polyphenols, including metabolism, bioavailability, and safety. The subsequent chapters deal with the numerous health benefits associated with consumption of green tea polyphenols. These include benefits related to cancer risk and prevention, cardiovascular disease, protection of internal organs, diabetes and weight management, bone and muscle health, allergies, oral care, inflammation, and gut health. The book addresses the nutrigenomics and proteomics of poyphenols. It also examines food and nonfood applications of green tea polyphenols, such as extracts, supplements, and skin and hair cosmetic products, demonstrating both therapeutic and functional health benefits. This book brings together a wide array of data on green tea polyphenols, providing a greater understanding of them and insight into their effects on human health, and their applications and commercial potential.

After water, tea signifies the second most frequently consumed beverage world-wide. Teas are not all the same; among the many areas of research that are included in this book are the effects of selenium-containing green tea on food consumption and body weight gain. Research shows that tea consumption may have its strongest effect among patients with cardiovascular disease. A specific chapter investigates whether green tea intake can reduce the risk of chronic obstructive pulmonary disease. Research is presented to show that green tea and its major constituent epigallocatechin gallate (EGCG) have a potential chemopreventative and/or treatment for a variety of diseases including breast cancer. Other research sheds new light on the molecular basis for the cancer-preventive activity of EGCG in vivo and helps in the design of new strategies to prevent cancer. A further study presents an analysis assessing the progress of research on the mechanisms pertaining to how telomerase activity is regulated by green tea in cancer cells. Further chapters look at the relationship of tea to diabetes and a description of the beneficial effects of green tea catechins on neuronal functions and neuronal diseases such as dementia. To improve biological functions and industrial applicability of green tea and its by-products, research is presented showing irradiation as a useful method.
