Book Description
Nutrition and Osteoporosis: Seeing Through a Glass, Darkly (1 Cor. 13:12) This volume of Advances in Nutritional Research deals with the present state of knowledge relative to the role of nutrition in the etiology of osteoporosis, one of the most serious degenerative diseases in the aging population. As a back drop for subsequent chapters on specific nutrients, Chapter 1 provides a com prehensive account of the gain and loss of bone throughout the life cycle, with emphasis on the architectural changes in later life that predispose to osteoporotic bone fractures. Chapter 2 documents the occurrence of aging bone loss through out human archeological history and Chapter 3 extends this documentation to all non-human vertebrate species so far examined, including primates living in the wild. It is apparent that a progressive loss of bone tissue is a normal accompaniment of aging among higher vertebrates. Whether it is a cause of bone fractures in animals, as it is in humans, is still unknown. It has also been established that there are significant differences in the frequency of osteoporotic fractures among human families, ethnic groups, national populations and diet cultures. Numerous studies have been carried out in an effort to explain these differences, and many of these deal with the possible effect of nutrition. Protracted controversies over the role of nutrition in the etiology of osteoporosis are reflected in the contents of several of the ensuing chapters.

Abstract: To determine the effects of protein, calcium, and phosphorus intake on calcium, phosphorus, and magnesium metabolism, calciuria was studied, and the effect of 2 levels of phosphorus on the calcium, phosphorus, and magnesium metabolisms at 2 levels of calcium was studied. An increase of phosphorus intake significantly decreased urinary calcium at both calcium intake levels, calcium absorption at 2400 mg calcium intake, and magnesium absorption and urinary magnesium, and significantly increased phosphorus absorption and urinary phosphorus. An increase of calcium intake significantly increased calcium absorption and urinary calcium, and significantly decreased phosphorus and magnesium absorption and urinary phosphorus and magnesium. Increase of dietary phosphorus increased phosphorus retention and increase of dietary calcium increased calcium retention but reduced magnesium retention. Increase of both phosphorus and calcium significantly decreased magnesium absorption and retention and urinary magnesium.

Book Description
Calcium and Phosphorus Metabolism focuses on the metabolism of calcium and inorganic phosphorus and covers topics ranging from the mechanism of calcium and phosphorus absorption in the intestine to calcium and phosphorus balances and retention. The results of balance experiments on the intestinal absorption of calcium and phosphorus are also presented. This book is comprised of 15 chapters and begins with an introduction to dietary sources of calcium and phosphorus, including water. The influence of vitamin D on the mechanism of calcium and phosphorus absorption in the intestine is then examined, along with calcium and phosphorus content of the body; recommended daily calcium and phosphorus requirements; calcium and phosphorus in the blood; and bone formation and resorption. The remaining chapters explore the chemical and organic composition of bone, together with theories of mineralization and the action of endocrine glands on bone as well as calcium and phosphorus metabolism. The final chapter is devoted to the metabolism of calcium and phosphorus in the teeth. This monograph will serve as a useful guide for biochemists and physiologists.

Book Description
We present to our readers the proceedings of the Second International Workshop on Phosphate. A short account of the history of the effort led to the Phosphate Workshops is appro priate and can be of interest to the reader. The idea for Phosphate Workshops was born in the early days of November, 1974. One of us (S. G. M. ) suggested the thought to a group of scientists gathered for a luncheon in one of the attrac tive small restaurants in Weisbaden, Germany. The purpose of the workshop was to bring together interested scientists to discuss the newer developments and the recent advances in the field of phosphate metabolism and the other related minerals. An Organizing Committee made of Shaul G. Massry (USA), Louis V. Avioli (USA), Philippe Bordier (France), Herbert Fleisch (Switzerland), and Eduardo Slatopolsky (USA) was formed. The First Workshop was held in Paris during June 5-6, 1975 and was hosted by Dr. Philippe Bordier. Its proceeding was already published. The Second Workshop took place in Heidelberg during June 28-30, 1976 and was hosted by Dr. Eberhard Ritz. Both of these workshops were extremely successful scientific endeavors, and the need for them was demonstrated by the great interest they generated among the scientific community. The Or ganizing Committee, therefore, decided to continue with the tradi tion to hold additional Workshops annually or every other year.
