A New Scientist Best Book of 2020 Our evolutionary ancestors once possessed the ability to intuit what food their bodies needed, in what proportions, and ate the right things in the proper amounts—perfect nutritional harmony. From wild baboons to gooey slime molds, most every living organism instinctually knows how to balance their diets, except modern-day humans. When and why did we lose this ability, and how can we get it back?

David Raubenheimer and Stephen Simpson reveal the answers to these questions in a gripping tale of evolutionary biology and nutritional science, based upon years of groundbreaking research. Their colorful scientific journey takes readers across the globe, from the foothills of Cape Town, to the deserts of Arizona, to a state-of-the-art research center in Sydney. Readers will encounter locusts, mice and even gorillas along the way as the scientists test their hypotheses on various members of the animal kingdom.

This epic scientific adventure culminates in a unifying theory of nutrition that has profound implications for our current epidemic of metabolic diseases and obesity. Raubenheimer and Simpson ultimately offer useful advice to understand the unwanted side effects of fad diets, gain control over one’s food environment, and see that delicious and healthy are integral parts of proper eating.

The first book to address nutrition''s complex role in biologyNutrition 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.
