Nutrition has long been considered more the domain of medicine and agriculture than of the biological sciences, yet it touches and shapes all aspects of the natural world. The need for nutrients determines whether wild animals thrive, how populations evolve and decline, and how ecological communities are structured. The Nature of Nutrition is the first book to address nutrition's enormously complex role in biology, both at the level of individual organisms and in their broader ecological interactions.
Stephen Simpson and David Raubenheimer provide a comprehensive theoretical approach to the analysis of nutrition--the Geometric Framework. They show how it can help us to understand the links between nutrition and the biology of individual animals, including the physiological mechanisms that determine the nutritional interactions of the animal with its environment, and the consequences of these interactions in terms of health, immune responses, and lifespan. Simpson and Raubenheimer explain how these effects translate into the collective behavior of groups and societies, and in turn influence food webs and the structure of ecosystems. Then they demonstrate how the Geometric Framework can be used to tackle issues in applied nutrition, such as the problem of optimizing diets for livestock and endangered species, and how it can also help to address the epidemic of human obesity and metabolic disease
Drawing on a wealth of examples from slime molds to humans, The Nature of Nutrition has important applications in ecology, evolution, and physiology, and offers promising solutions for human health, conservation, and agriculture.

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
"Debates continue to rage about what diet is best, in part because an underlying theoretical framework for choosing one over another has been lacking. Not so any longer. The Nature of Nutrition demystifies the complexity of nutrition and diet choice and shows why people and other creatures eat the way they do. Along the way, readers learn about the adaptive value of cannibalism, the impact of diet on sex lives, how dietary choices affect entire ecosystems, and so much more."--Daniel Rubenstein, Princeton University
"The Nature of Nutrition is a must-read for anyone interested in the role nutrition plays in the survival of the fittest. Starting with the Origin of Species, Simpson and Raubenheimer guide us through the nutritional strategies that maintained reproductive health and mating behaviors despite periods of food shortage and danger from predators. The protein leverage hypothesis provides a solid foundation to explain the growing global epidemic of human obesity."--Eric Ravussin, Pennington Biomedical Research Center, Louisiana State University System
