To show that nutrition science, with its application to food and nutrition policy, now needs a new conceptual framework. This will incorporate nutrition in its current definition as principally a biological science, now including nutritional aspects of genomics. It will also create new governing and guiding principles; specify a new definition; and add social and environmental dimensions and domains.
A narrative review of nutrition science, its successes and achievements, and its dilemmas, paradoxes, shortcomings, dissonances and challenges. Reference is made to 16 associated papers. Equal use is made of continuous text and of boxed texts that extend the review and give salient examples.
Recent and current interrelated electronic and genomic discoveries and linked sequential demographic, nutritional and epidemiological shifts, in the context of associated and interlinked global social, cultural, environmental, economic, political and other developments, altogether amount to a world in revolution, requiring all disciplines including that of nutrition science to make comparably radical responses.
Nutrition in principle and practice should be a biological and also an environmental and social science. This new broad integrated structure brings much recent and current progressive work into the centre of nutrition science, and in some ways is a renewal of the period when nutrition science had its greatest impact. It amounts to a map charting well-known and also new worlds. The new nutrition science is concerned with personal and population health, and also with planetary health--the welfare and future of the whole physical and living world of which humans are a part. In this way the discipline will make a greater contribution to the preservation, maintenance, development and sustenance of life on Earth, appropriate for the twenty-first century.
表明营养科学及其在食品和营养政策中的应用现在需要一个新的概念框架。这个框架将把营养纳入其当前主要作为一门生物科学的定义中，现在还包括基因组学的营养方面。它还将创建新的管理和指导原则；明确一个新的定义；并增加社会和环境维度及领域。
对营养科学、其成功与成就以及困境、悖论、缺点、不协调和挑战进行叙述性综述。参考了16篇相关论文。对连续文本和扩展综述并给出突出例子的盒装文本同等使用。
在相关联且相互联系的全球社会、文化、环境、经济、政治及其他发展的背景下，近期和当前相互关联的电子和基因组发现以及相关的连续人口、营养和流行病学转变，共同构成了一个处于变革中的世界，要求包括营养科学在内的所有学科做出同样激进的回应。
营养在理论和实践上都应该是一门生物科学，同时也是一门环境和社会科学。这种新的广泛综合结构将许多近期和当前的前沿工作置于营养科学的核心，在某些方面是营养科学产生最大影响时期的一次复兴。它相当于一张描绘已知世界和新领域的地图。新的营养科学关注个人和人群健康，也关注地球健康——人类作为其中一部分的整个物质和生物世界的福祉与未来。通过这种方式，该学科将为二十一世纪地球上生命的保护、维持、发展和维系做出更大贡献。
