 | Dietary Phosphorus: Health, Nutrition, and Regulatory Aspects Phosphorus is an essential nutrient that occurs in almost all foods and is important for many normal physiological functions. In a typical Western diet, it is not harmful, but does adversely affect tissues in the body when consumed in excess or deficiency. This book provides a comprehensive review of various aspects of phosphorus in relation to human nutritional needs. Sections cover phosphorus nutrition and dietary issues; health risks associated with excess phosphorus intake that exceeds requirements; phosphorus intake in populations at risk; regulatory challenges and policy approaches; and environmental impacts of phosphates in the modern food supply. This book challenges the long held ideas that high dietary phosphorus intake beyond nutritional requirements is safe and the natural supply of phosphorus critical to agricultural and human food production is endless. Controversy surrounds the claim that largely unrestricted use of phosphorus in all aspects of food production from farm to fork increases dietary phosphorus intake and irretrievable environmental loss, both of which harm human and environmental health. The book editors have joined together experts in basic, medical, environmental, nutritional, and food science to explore the validity of these claims of harm from high intakes and the unchecked use of phosphorus in the global food supply. Despite the essential need for adequate phosphorus over all stages of plant, animal and human life, the growing evidence points to a worldwide increase in dietary phosphorus intake far beyond nutrient requirements, significant association with chronic disease risk even when renal function is not compromised, and the increase in environmental loss with crop run-off, animal husbandry, and unretrieved phosphorus from human waste. This current evidence alludes to a depleted, unsustainable natural supply of phosphorus, hazardous environmental pollution of lakes and waterways, and significant increases in the risk of kidney, skeletal, and other serious illnesses in humans in the future if action is not taken now. Jaime Uribarri, MD Dr. Jaime Uribarri is a physician and clinical investigator. He was born in Chile and received his medical degree from the University of Chile School of Medicine. He did all his postgraduate training in the United States. He has been in The Icahn School of Medicine at Mount Sinai, New York, since 1990, where he is currently Professor of Medicine and Director of the Renal Clinic and the Home Dialysis Program at the Mount Sinai Hospital. In parallel with his clinical activities, Dr Uribarri has been very active in clinical investigation for the past 30 years. His main areas of research have been on acid-base and fluid and electrolyte disorders, as well as nutrition in chronic kidney disease and diabetic patients. He was one of the first to bring attention to the important role of food-derived advanced glycation end products (AGEs) in chronic diseases in humans. He has published over 150 peer-reviewed papers and written many chapters in books. He has lectured extensively on these research topics in New York City, as well as in national and international meetings. He serves as an ad hoc referee for numerous nutrition, medical, and other scientific journals, and he is an active member of several health organizations and professional associations, including The American Society of Nephrology, The American Society of Nutrition, The International Society of Nephrology, The New York Academy of Sciences, and The Maillard Society. Mona S. Calvo, PhD After earning a doctorate in Nutritional Sciences from the University of Illinois, Champaign-Urbana, Dr. Calvo pursued postdoctoral studies in the Endocrine Research Unit of the Mayo Clinic in Rochester, Minnesota. Recently retired from the Food and Drug Administration (FDA) after 28 years, her former position and title was that of Expert Regulatory Review Scientist and Research Principal Investigator at the FDA's Center for Food Safety and Applied Nutrition. Her current and past research interests focus on dietary influences on the hormonal regulation of calcium, phosphorus, and vitamin D and their impact on bone and kidney disease and other chronic diseases of public health significance. These research interests have been the topics for over 150-peer-reviewed manuscripts, book chapters, government reports/guidelines, FDA regulations, and abstracts presented at national and international meetings. She serves as an Associate Editor for Public Health Nutrition ; an ad hoc referee for numerous nutrition, medical, and other scientific journals; and is a member of the Endocrine Society, American Society for Nutrition, the Nutrition Society (UK), and the American Society for Bone and Mineral Research and serves as a member of the advisory board for ODIN, which seeks food-based solutions for optimal vitamin D nutrition and health through the life cycle. |
