Nutritional Aspects of Osteoporosis is based on presentations given at the Fifth International Symposium on Nutritional Aspects of Osteoporosis held in Lausanne, Switzerland in 2003. Although an often neglected chapter of medical research, the nutritional influences on bone health was a discussed topic at this congress. Also discussed were new insights into the role of proteins, vitamins, potassium, vegetables, food acid load, mineral waters and calcium.
