"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.

A Story of Ruins

This richly illustrated book examines the changing significance of ruins as vehicles for cultural memory in Chinese art and visual culture from ancient times to the present. The story of ruins in China is different from but connected to ‘ruin culture’ in the West. This book explores indigenous Chinese concepts of ruins and their visual manifestations, as well as the complex historical interactions between China and the West since the eighteenth century. Wu Hung leads us through an array of traditional and contemporary visual materials, including painting, architecture, photography, prints and cinema. A Story of Ruins shows how ruins are integral to traditional Chinese culture in both architecture and pictorial forms. It traces the changes in their representation over time, from indigenous methods of recording damage and decay in ancient China, to realistic images of architectural ruins in the nineteenth and twentieth centuries, to the strong interest in urban ruins in contemporary China, as shown in the many artworks that depict demolished houses and decaying industrial sites. The result is an original interpretation of the development of Chinese art, as well as a unique contribution to global art history.

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.

Millions of Americans follow the "best" medical advice every day to prevent heart attacks -- eating the standard low-fat, high-carbohydrate diet so widely recommended by doctors -- but in fact they are placing themselves at greater risk for heart disease. In Syndrome X: Overcoming the Silent Killer That Can Give You a Heart Attack, Dr. Gerald Reaven, the world-renowned physician who identified and named this silent killer, explains why the standard heart-healthy diet can be dangerous and lays out a simple six-step program to reduce the risk of heart disease for everyone. The problem stems from a little-known cluster of metabolic abnormalities known as Syndrome X. The insulin resistance that lies at the heart of the syndrome can turn normal rules of good health upside down and dramatically increase the risk of heart disease. Fortunately, Syndrome X can be cured. This important book explains how to identify the disorder and provides a program of diet and exercise (plus medication when necessary) that can render Syndrome X harmless. Tested in carefully controlled research settings and in practice, this remarkable new approach has the ability to reduce the risk of heart attacks and heart disease for all of us. Dr. Reaven shows how eating a diet relatively high in "good" fats (40 percent of calories) can dramatically lower the risk of heart disease if you have Syndrome X. The approach seems paradoxical: Everyone "knows" that fat is bad, so how can more fat possibly lead to better health? The answer lies in the type of fat and the body chemistry of the people who consume it. If you have the abnormal metabolism called Syndrome X, eating a low-fat, high-carbohydrate diet to lower your LDL and blood fats won't protect you. In fact, doing so will increase the odds of heart disease. Millions of Americans have the potentially deadly, yet easily identifiable signs of Syndrome X -- but few cases are detected in time, because most physicians don't know what to look for. This trailblazing book will change that, making doctors and patients aware of the problem -- and its easy solution, an integrated program of diet and exercise that simultaneously reduces all the risk factors for heart disease, including Syndrome X. Dr. Reaven's discovery of Syndrome X has shown us that the standard approach to preventing heart disease is dangerous for many of us. Now, his safe, proven new approach explains how millions can drastically reduce their risk of heart disease. His program works not only for those who have Syndrome X, but also for anyone who simply wants to reduce the risk of heart disease.
