Antioxidants In Food And Biology

Designed to help all those who need to prevent or control oxidation, especially in food products, or to understand the properties of antioxidants in food, nutrition, health and medicine, this title covers chapters such as the chemistry of antioxidation, antioxidant action in multi-phase systems, antioxidants in biology, and among other topics. The field of antioxidants has expanded over the last six decades into a wide variety of multi-disciplinary areas that impact foods and health. Antioxidants in food and biology: Facts and fiction is a handbook designed to help all those who need to prevent or control oxidation, especially in food products, or to understand the properties of antioxidants in food, nutrition, health and medicine. It conveys the complexity of antioxidant chemistry by providing an appreciation of the various phenomena that affect oxidation and its inhibition in foods and biological systems. Beginning with the underlying chemistry, the book moves on to explain how the activity of antioxidants is affected at the interface of complex multiphase lipid systems and to discuss the problems of evaluating the activities of antioxidants in foods and biological systems. After reviewing the antioxidants present in various foods, the author addresses the hypothesis that the health of an individual is influenced by the efficiency of various protection systems against oxidant damage. He also considers whether or not additional or more effective natural antioxidants are needed in our diet to reduce oxidative stress from dietary and environmental factors, and to thus reduce the risk of cardiovascular disease.

Food antioxidants are of primary importance for the preservation of food quality during processing and storage. However, the status of food depends on a balance of antioxidants and prooxidants occurring in food. Food Oxidants and Antioxidants: Chemical, Biological, and Functional Properties provides a single-volume reference on the effects of natur

Antioxidants in Food, Vitamins and Supplements bridges the gap between books aimed at consumers and technical volumes written for investigators in antioxidant research. It explores the role of oxidative stress in the pathophysiology of various diseases as well as antioxidant foods, vitamins, and all antioxidant supplements, including herbal supplements. It offers healthcare professionals a rich resource of key clinical information and basic scientific explanations relevant to the development and prevention of specific diseases. The book is written at an intermediate level, and can be easily understood by readers with a college level chemistry and biology background. Covers both oxidative stress-induced diseases as well as antioxidant-rich foods (not the chemistry of antioxidants) Contains easy-to-read tables and figures for quick reference information on antioxidant foods and vitamins Includes a glycemic index and a table of ORAC values of various fruits and vegetables for clinicians to easily make recommendations to patients

This is the first book to integrate the biological, nutritional, and health aspects of antioxidant status. Fifty contributors integrate and transfer the knowledge of free radicals and antioxidants from the test tube to the laboratory of the biologist, clinical nutritionist, and medical researcher, as well as to the office of the dietician, nutritionist, and physician. Topics examined include factors affecting and methods for evaluating antioxidant status in humans; effect of diet and physiological stage (infancy, aging, exercise, alcoholism, HIV infection, etc.) on antioxidant status; and the role of antioxidant status in nutrition, health, and disease.

Diabetes: Oxidative Stress and Dietary Antioxidants, Second Edition, builds on the success of the first edition, covering updated research on the science of oxidative stress in diabetes and the potentially therapeutic usage of natural antioxidants in the diet and food matrix. The processes within the science of oxidative stress are not described in isolation, but rather in concert with other processes, such as apoptosis, cell signaling and receptor mediated responses. This approach recognizes that diseases are often multifactorial and oxidative stress is a single component of this. Since the publication of the first edition, the science of oxidative stress and free radical biology continues to rapidly advance with thousands of the research articles on the topic. New sections in this update cover the role of dietary advanced glycation end products (AGEs) in causing OS in diabetes, oxidative stress and diabetes-induced bone metabolism, and oxidative stress and diabetic foot ulcer. Saves clinicians and researchers time in quickly accessing the very latest details on a broad range of diabetes and oxidation issues Combines the science of oxidative stress and the putative therapeutic usage of natural antioxidants in the diet, its food matrix or plant Includes preclinical, clinical and population studies to help endocrinologists, diabetologists, nutritionists, dieticians and clinicians map out key areas for research and further clinical recommendations

Antioxidant Food Supplements in Human Health discusses new discoveries in the areas of oxygen and nitric oxide metabolism and pathophysiology, redox regulation and cell signaling, and the identification of natural antioxidants and their mechanisms of action on free radicals and their role in health and disease. An essential resource for researchers, students, and professionals in food science and nutrition, gerontology, physiology, pharmacology, and related areas. Health effects of antioxidant nutrients Nutrients of vitamins C and E, selenium, alpha-lipoic acid, coenzyme Q10, carotenoids, and flavonoids Natural source antioxidants, including pine bark, ginko biloba, wine, herbs,uyaku, and carica papaya

The material presented in this book deals with basic mechanisms of free radical reactions in autoxidation processes and anitoxidant suppression of autoxidation of foods, biochemical models and biologi cal systems. Autoxidation in foods and corresponding biological effects are usually approached separately although recent mechanistic developments in the biochemistry and free radical chemistry of per oxides and their precursors tend to bring these two fields closer. Apparent ability of antioxidants in diets to reduce the inci dence of cancer has resulted in scrutiny of autoxidized products and their precursors as possibly toxic, mutagenic and carcinogenic agents. Mechanisms of any of these effects have been barely ad dressed. Yet we know now that free radicals, as esoteric as they were only a few decades ago, are being discovered in foods, biochem ical and biological systems and do play a role in the above-mentioned causalities. The purpose of the Workshop and the resulting book was to give a unifying approach towards study of beneficial and deleterious effects of autoxidation, based on rigorous scientific considerations. It is our hope that the material presented in this book will not only provide a review of the "state of the art" of autoxidation and anti oxidants, but also reflect the interaction which occurred during the Workshop between workers using model sytems, and food and biological systems.

In the recent years, considerable research has been carried out evaluating natural substances as antioxidative additives in food products, leading to novel combinations of antioxidants and the development of novel food products. In addition to their antioxidative capacity, these natural additives have positive effects on the human body with documented health benefits. This valuable new book provides an overview of natural antioxidants, their sources, methods of extraction, regulatory aspects, and application techniques, specifically focusing on different foods of animal origin to improve their oxidative stability.
