Описание: Why an encyclopedia? The original Greek word means 'the circle of arts and sciences essential for a liberal education', and such a book was intended to embrace all knowledge. That was the aim of the famous Encyclopedie produced by Diderot and d'Alembert in the middle of the 18th century, which contributed so much to what has been called the Enlightenment. It is recorded that after all the authors had corrected the proofs of their contributions, the printer secretly cut out whatever he thought might give offence to the king, mutilated most of the best articles and burnt the manuscripts! Later, and less controversially, the word 'encyclopedia' came to be used for an exhaustive repertory of information on some particular department of knowledge. It is in this class that the present work falls.
In recent years the scope of Human Nutrition as a scientific discipline has expanded enormously. I used to think of it as an applied subject, relying on the basic sciences of physiology and biochemistry in much the same way that engineering relies on physics. That traditional relationship remains and is fundamental, but the field is now much wider. At one end of the spectrum epidemiological studies and the techniques on which they depend have played a major part in establishing the relationships between diet, nutritional status and health, and there is greater recognition of the importance of social factors. At the other end of the spectrum we are becoming increasingly aware of the genetic determinants of ways in which the body handles food and is able to resist adverse influences of the environment. Nutritionists are thus beginning to explore the mechanisms by which nutrients influence the expression of genes in the knowledge that nutrients are among the most powerful of all influences on gene expression. This has brought nutrition to the centre of the new 'post-genome' challenge of understanding the effects on human health of gene-environment interactions.
In parallel with this widening of the subject there has been an increase in opportunities for training and research in nutrition, with new departments and new courses being developed in universities, medical schools and schools of public health, along with a greater involvement of schoolchildren and their teachers. Public interest in nutrition is intense and needs to be guided by sound science. Governments are realizing more and more the role that nutrition plays in the prevention of disease and the maintenance of good health, and the need to develop a nutrition policy that is integrated with policies for food production.
The first edition of the Encyclopaedia of Human Nutrition established it as one of the major reference works in our discipline. The second edition has been completely revised to take account of new knowledge in our rapidly advancing field. This new edition is as comprehensive as the present state of knowledge allows, but is not overly technical and is well supplied with suggestions for further reading. All the articles have been carefully reviewed and although some of the subjects are controversial and sensitive, the publishers have not exerted the kind of political censorship that so infuriated Diderot.


The science of human nutrition and its applications to health promotion continue to gain momentum. In the relatively short time since the release of the first edition of this Encyclopedia, a few landmark discoveries have had a dramatic multiplying effect over nutrition science: the mapping of the human genome, the links between molecular bioenergetics and lifespan, the influence of nutrients on viral mutation, to name a few.

But perhaps the strongest evidence of the importance of nutrition for human health comes from the fact that almost 60% of the diseases that kill humans are related to diet and lifestyle (including smoking and physical activity). These are all modifiable risk factors. As inpiduals and organizations intensify their efforts to reduce disease risks, the need for multidisciplinary work becomes more apparent. Today, an effective research or program team is likely to include several professionals from fields other than nutrition. For both nutrition and non-nutrition scientists, keeping up to date on the concepts and interrelationships between nutrient needs, dietary intake and health outcomes is essential. The new edition of the Encyclopedia of Human Nutrition hopes to address these needs. While rigorously scientific and up to date, EHN provides concise and easily understandable summaries on a wide variety of topics. The nutrition scientist will find that the Encyclopedia is an effective tool to ''fill the void'' of information in areas beyond his/her field of expertise. Professionals from other fields will appreciate the ease of alphabetical listing of topics, and the presentation of information in a rigorous but concise way, with generous aid from graphs and diagrams.

For a work that involved more than 340 authors requires, coordination and attention to detail is critical. The editors were fortunate to have the support of an excellent team from Elsevier's Major Reference Works pision. Sara Gorman and Paula O'Connell initiated the project, and Tracey Mills and Samuel Coleman saw it to its successful completion.

We trust that this Encyclopedia will be a useful addition to the knowledge base of professionals involved in research, patient care, and health promotion around the globe.
