Stephen J. Simpson is an Australian Research Council Laureate Fellow in the School of Biological Sciences and academic director of the Charles Perkins Centre for the Study of Obesity, Diabetes, and Cardiovascular Disease at the University of Sydney. David Raubenheimer is professor of nutritional ecology at Massey University in New Zealand.
"The geometric framework (GF), introduced into scientific literature a decade ago, brings a new degree of clarity to the discipline of nutrition. Simpson and Raubenheimer highlight species-, habitat-, and tropic-level examples to truly demonstrate the universality of the concepts GF encompasses, providing coherent explanations of numerous interactions and variables--physical, biochemical, chemical, physiological, anatomical--that must be considered when discussing nutrition... The authors successfully demonstrate that nutrition serves as a foundation that integrates the biological sciences."--Choice "[T]his strikingly well-written book, covering a wide range of issues in nutritional biology, is bound to inspire nutritional scientists, biologists, ecologists as well as medical doctors and nurse practitioners involved in the treatment of nutrition related disease. In addition, I believe that the clear language and enlightening examples allow for the educated layman interested in biology to be astonished by the enormous implications of the nature of nutrition."--Hanno Pijl, American Journal of Human Biology
