"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 "A fascinating and authoritative treatment of nutrition in an ecological and evolutionary framework. Simpson and Raubenheimer's novel perspective crosses disciplines, from the organism to the population to the ecosystem, providing a long-needed unifying framework to what has previously largely been the domain of clinical science."--Simon A. Levin, Princeton University "This outstanding book provides the first comprehensive theoretical framework for analyzing the roles of nutrition across a huge swath of fields, from ecology and evolution to conservation and human health." The Nature of Nutrition" is creative and scholarly yet approachable. I know of no other book like it."--Bernard J. Crespi, Simon Fraser University ""The Nature of Nutrition" covers a vast range of issues, from reproduction, immunology, and toxicology to insect migration, population ecology, predator-prey interactions, and ecosystem functioning, as well as applied issues such as conservation biology and human nutritional pathologies. I enjoyed each and every chapter of this excellent book."--Kenneth Wilson, Lancaster University

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.

What Is Fat For

Obesity science has reached a crossroads: The carbohydrate hypothesis is poised to overtake "calories in, calories out" as the predominant understanding of weight gain. Physicians, dietitians and trainers have come to treat "carbs are bad" as a new gospel, preaching a lifestyle that strays very far from the true scientific consensus. In "What Is Fat For?" Ignatius Brady, a weight loss physician and science writer, presents a fresh perspective on obesity based on critical new research that has gone largely overlooked. The protein leverage hypothesis holds that neither dietary fat nor dietary carbohydrate "cause" us to gain weight. The issue is re-framed and discussed as an imbalance between "protein" and "non-protein" energy. A current imbalance in our food supply has caused a widespread human adaptation: the obesity epidemic. In a thorough yet readable style, the book takes the reader through normal human weight regulation, the time frame needed for weight loss, and what's missing in the "carbs are bad" thinking. This is not a diet book, but a scientific exploration of the inner workings of human biology and our interactions with the modern nutritional environment. The question, "What is fat for?" drives this narrative, which takes nothing for granted, analyzes all possibilities and presents detailed evidence for the reader's best judgment. Biases are overturned, accepted wisdom is re-considered and new answers are discovered.

Everyone eats, but rarely do we investigate why we eat what we eat. Why do we love spices, sweets, coffee? How did rice become such a staple food throughout so much of eastern Asia? Everyone Eats examines the social and cultural reasons for our food choices and provides an explanation of the nutritional reasons for why humans eat what they do, resulting in a unique cultural and biological approach to the topic. E. N. Anderson explains the economics of food in the globalization era; food’s relationship to religion, medicine, and ethnicity; and offers suggestions on how to end hunger, starvation, and malnutrition. This thoroughly updated Second Edition incorporates the latest food scholarship, most notably recognizing the impact of sustainable eating advocacy and the state of food security in the world today. Anderson also brings more insight than ever before into the historical and scientific underpinnings of our food customs, fleshing this out with fifteen new and original photographs from his own extensive fieldwork. A perennial classic in the anthropology of food, Everyone Eats feeds our need to understand human ecology by explaining the ways that cultures and political systems structure the edible environment.

Handbook of Diet and Nutrition in the Menstrual Cycle Periconception and Fertility

The reproductive cycle in women is complex and can be considered to begin with epigenetic programming and ending with menopause. Intervening steps involve a variety of processes, including the cellular development of the sex organs, menarche, episodic endocrine cycles, menstruation, ovulation and conception. These processes can be influenced by diet and nutrition and vice versa. Body composition has an impact on the menstrual cycle and periconception and these factors in turn also influence body composition. Similarly, either food deprivation, dietary excess or obesity can result in marked changes in the menstrual cycle with a concomitant effect on fertility. This handbook is the first scientific source that provides a comprehensive overview of the relationship of diet and nutrition with puberty, menarche and menstrual cycle, conception and fertility and infertility. The handbook of diet and nutrition in the menstrual cycle, conception and fertility will benefit dieticians, nutritionists, gynaecologists, endocrinologists, obstetricians, paediatricians and those concerned with women's health in general.

A revolutionary examination of why we age, what it means for our health, and how we just might be able to fight it. In Cracking the Aging Code, theoretical biologist Josh Mitteldorf and award-winning writer and ecological philosopher Dorion Sagan reveal that evolution and aging are even more complex and breathtaking than we originally thought. Using meticulous multidisciplinary science, as well as reviewing the history of our understanding about evolution, this book makes the case that aging is not something that “just happens,” nor is it the result of wear and tear or a genetic inevitability. Rather, aging has a fascinating evolutionary purpose: to stabilize populations and ecosystems, which are ever-threatened by cyclic swings that can lead to extinction. When a population grows too fast it can put itself at risk of a wholesale wipeout. Aging has evolved to help us adjust our growth in a sustainable fashion as well as prevent an ecological crisis from starvation, predation, pollution, or infection. This dynamic new understanding of aging is provocative, entertaining, and pioneering, and will challenge the way we understand aging, death, and just what makes us human.
