The nature of nutrition : a unifying framework from animal adaptation to human obesity / Stephen J. ...

the nature of nutrition simpson stephen j raubenheimer david

First, foods are complex mixtures of multiple components, each of which has its own functional implications for the animal. This leads to savoury-flavoured food that makes us think we're eating protein when in reality it is loaded with carbohydrates and fats. 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. 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. They have, however, contributed little to understanding which nutrients or combinations of nutrients actually do influence foraging, and how the requirements of animals for these influence ecological processes. A synthesis of this body of work can be found in The Nature of Nutrition: a Unifying Framework from Animal Adaptation to Human Obesity, published in May 2012 by Princeton University Press.

With this book, we may start to do that more effectively. The weight of evidence indicates that the primary driver of the obesity epidemic in recent decades has been increased intake, rather than decreased energy expenditure. We could continue indefinitely, expanding the range of nutrients, contexts, and problems. As a layman engineer this book was heavy going, but worth the effort. Buy The Nature of Nutrition! Indeed, in many animal systems the spatial and temporal patterns of reproduction are tightly geared toward resource availability.

Much of biology over the past 150 years has been focused on unraveling this complexity. 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. I know of no other book like it. This is not totally new. To buy this book at the lowest price,. The need for nutrients determines whether wild animals thrive, how populations evolve and decline, and how ecological communities are structured.

Second, a given food component at a stipulated dose can have multiple influences on an animal; we encountered an example above, where carotenoids in zooplankton influenced both resistance to the harmful effects of solar radiation and the risk of predation. I know of no other book like it. Carotenoids are important not only in signaling and health but also in vision Toomey and McGraw 2009. 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. 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.

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. 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. For example, recruitment of kittiwake gulls is higher when lipid-rich fish are available compared with lipid-poor species. 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. Finch, Quarterly Review Of Biology Stephen J. In this way, engineered foods subvert the appetite control systems that should be helping to balance the consumption of macronutrients. Similar nutrient-specific responses have been observed in predatory beetles as they emerge from winter diapause: they initially select a diet high in fat relative to protein, and as the body fat that was depleted during the previous winter is replenished, they increase their intake of protein to meet reproductive demands Raubenheimer et al.

It builds the components of organisms, and fuels the dynamic interactions between these components; it determines whether or not wild animals thrive, how their populations grow, decline, and evolve, and how assemblages of interacting species ecological communities and ecosystems are structured. Also, they charge optimal foraging theorists with looking only at bulk calories, but at least in anthropology we have been looking at protein and minerals for quite a few years now. The need for nutrients determines whether wild animals thrive, how populations evolve and decline, and how ecological communities are structured. It was most frustrating that the graphs used did not reproduce clearly in Kindle. .

The authors successfully demonstrate that nutrition serves as a foundation that integrates the biological sciences. This is now happening in humans, as we live in a foodscape scarcely recognizable to our forebears. 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. Third, most aspects of animal function are influenced by many food components—predation risk, for example, is influenced both by the level of carotenoids stored in the body of a zooplankter i. Ullman chair in nutritional ecology and nutrition theme leader at the Charles Perkins Centre. 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. The range of processed food becoming available is evolving faster than our appetite control systems.

These involve choosing the right foods, deciding how much of each to eat, regulating the efficiency with which nutrients are retained in the body, and regulating the amounts of retained nutrients that are allocated to different functions such as energy metabolism, energy and nutrient storage, tissue growth, secretions, and so on. Includes bibliographical references and index. On closer inspection, however, even these apparently simple cases are deceptively complex. Buy it for a smart friend of yours. The higher cost of protein drives consumers to buy cheaper processed food loaded with fat and carbohydrates — an effect that disproportionately affects people on tighter budgets. Natural selection has given them an amazing ability to sense what plants or animals are best for them--sometimes their own dead are best and they become cannibals.

I know of no other book like it. Beschreibung Zusammenfassung Addresses nutrition's complex role in biology, both at the level of individual organisms and in their broader ecological interactions. In most cases these food components will be nutrients but, as discussed in chapter 5, this is not invariably the case. The protein leverage hypothesis provides a solid foundation to explain the growing global epidemic of human obesity. I enjoyed each and every chapter of this excellent book. 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. If their physiology reflects their ancestral diet, they may have appetite systems that strive for an even higher protein intake than populations whose ancestors switched earlier to an agricultural lifestyle with a high-carbohydrate diet.

The first believable scientific approach to nutritcian I have come across. Stephen Simpson and David Raubenheimer provide a comprehensive theoretical approach to the analysis of nutrition--the Geometric Framework. Darwin demonstrated in his book that a few biological facts—what he refers to as laws—combine to provide an elegantly simple natural mechanism that can explain the origin of the diverse and elaborately constructed plants and animals in his entangled bank. But this approach misses a fundamental point. 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. Many species of butterflies, for example, forage only for nectar, which consists largely of energy-rich sugars and water.
