Interest in the science of exercise dates back to the time of ancient Greece. Today exercise is viewed not only as a leisurely activity but also as an effective preventive and therapeutic tool in medicine. Further biomedical studies in exercise physiology and biochemistry reports that strenuous physical exercise might cause oxidative lipid damage in various tissues. The generation of reactive oxygen species is elevated to a level that overwhelms the tissue antioxidant defense systems resulting in oxidative stress. The Handbook of Oxidants and Antioxidants in Exercise examines the different aspects of exercise-induced oxidative stress, its management, and how reactive oxygen may affect the functional capacity of various vital organs and tissues. It includes key related issues such as analytical methods, environmental factors, nutrition, aging, organ function and several pathophysiological processes. This timely publication will be of relevance to those in biomedical science and was designed to be readily understood by the general scientific audience.

The Handbook of Nutrition, Diet and the Eye is the first book to thoroughly address common features and etiological factors in how dietary and nutritional factors affect the eye. The ocular system is perhaps one of the least studied organs in diet and nutrition, yet the consequences of vision loss can be devastating. One of the biggest contributors to complete vision loss in the western hemisphere is diabetes, precipitated by metabolic syndrome. In some developing countries, micronutrient deficiencies are major contributory factors to impaired vision. However, there are a range of ocular defects that have either their origin in nutritional deficiencies or excess or have been shown to respond favorably to nutritional components. The eye from the cornea to the retina may be affected by nutritional components. Effects may be physiological or molecular. This book represents essential reading for nutritionists, dietitians, optometrists, ophthalmologists, opticians, endocrinologists, and other clinicians and researchers interested in eye health and vision in general. Saves clinicians and researchers time in quickly accessing the very latest details on a broad range of nutrition, ocular health, and disease issues Provides a common language for nutritionists, nutrition researchers, optometrists, and ophthalmologists to discuss how dietary and nutritional factors, and related diseases and syndromes affect the eye Preclinical, clinical, and population studies will help nutritionists, dieticians, and clinicians map out key areas for research and further clinical recommendations

Processing and Impact on Antioxidants in Beverages presents information key to understanding how antioxidants change during production of beverages, how production options can be used to enhance antioxidant benefit, and how to determine the production process that will result in the optimum antioxidant benefit while retaining consumer acceptability. In the food industry, antioxidants are added to preserve the shelf life of foods and to prevent off-flavors from developing. These production-added components also contribute to the overall availability of essential nutrients for intake. Moreover, some production processes reduce the amount of naturally occurring antioxidants. Thus, in terms of food science, it is important to understand not only the physiological importance of antioxidants, but what they are, how much are in the different food ingredients, and how they are damaged or enhanced through the processing and packaging phases. This book specifically addresses the composition and characterization of antioxidants in coffee, green tea, soft drinks, beer, and wine. Processing techniques considered here include fermentation and aging, high-pressure homogenization, enzymatic debittering, and more. Lastly, the book considers several selective antioxidant assays, such as Oxygen Radical Absorbance Capacity (ORAC) and Trolox Equivalent Antioxidant Capacity (TEAC) assays. Provides insights into processing options for enhanced antioxidant bioavailability Presents correlation potentials for increased total antioxidant capacity Includes methods for the in situ or in-line monitoring of antioxidants to reduce industrial loss of antioxidants in beverages Proposes processing of concentrated fractions of antioxidants that can be added to foods
Pathology: Oxidative Stress and Dietary Antioxidants bridges the disciplinary knowledge gap to help advance medical sciences and provide preventative and treatment strategies for pathologists, health care workers, food scientists and nutritionists who have divergent skills. This is important as oxidative stress can be ameliorated with pharmacological, nutraceutical or natural agents. While pathologists and clinical workers understand the processes in disease, they are less conversant in the science of nutrition and dietetics. Conversely, nutritionists and dietitians are less conversant with the detailed clinical background and science of pathology. This book helps to fill those gaps. Saves clinicians and researchers time by helping them to quickly access the very latest details on a broad range of pathologies and oxidation issues Combines the science of oxidative stress and the putative therapeutic usage of natural antioxidants in the diet Includes preclinical, clinical and population studies to help pathologists, nutritionists, dieticians, and clinicians map out key areas for research and further clinical recommendations
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
