This book is a publication of the 4th International Symposium on Nutritional Aspects of Osteoporosis held in May 2000. The symposium was sponsored by several pharmaceutical companies and contributing partners, including the Swiss Dairy Producers.
The book is divided into 8 parts, which most likely correlate with each half-day session of the meeting: "Early influences: childhood and adolescence"; "Calcium"; "Dairy"; "Vitamin D"; "Proteins"; "Trace elements, vitamin A, vitamin K"; "Estrogen, phytoestrogens, body weight"; and "Food composition and acid-base metabolism." Leaders in the field of bone metabolism wrote the 33 chapters. The contributors are from all parts of Europe and the United States. The chapters vary in length and depth depending on the contributing author; however, most chapters include tables, figures, diagrams, and data from recent clinical trials. For the most part, references are up-to-date; however, few papers were published later than 1999.
Some of the highlights include good chapters on the epidemiology of bone acquisition, calcium supplementation in the young and in older adults, dietary calcium absorption and bioavailability, and alterations with advancing age. One section is devoted to the unique properties of milk and its nutrients and their effects on bone formation and bone density maintenance.
The section on trace elements and fat-soluble vitamins features a complete discussion of the role of vitamin K and delves into the uncertainties surrounding the role of retinoids. Issues related to alterations in bone metabolism during pregnancy and lactation are discussed for both single and multiple births. In addition to covering the effects of phytoestrogens and acid-base balance on bone density, the last 2 chapters discuss bone nutrients within their food groupings and examine the role of calcium in the setting of other nutrients supplied by specific food groups.
This book offers a taste of various nutrition-related and bone health topics. The book also provides a nice overview of osteoporosis and gives the more knowledgeable reader an updated review. Those looking for comprehensive coverage of these topics should look elsewhere. I recommend this book for nutritionists who want only an overview of the nutritional aspects of osteoporosis or for graduate students looking for opportunities for research in this subject area.
