Nutrition Biophysics

Do you no longer understand the countless, contradictory dietary recommendations? Do you find it difficult to distinguish between good and bad when it comes to cholesterol? Are you torn between the various dietary rules and nutritional forms that come your way every day and despair of the term "healthy diet"? Or are you confronted professionally, e.g. as a consultant or fitness coach, with questions on the subject of nutrition and would like to learn the scientific basics? The author Thomas Vilgis advises you to remain calm and to think objectively about all assumptions, presumptions, promises and suggestions for orientation. This book leads you off the beaten track and with a scientific, sober view to fundamental questions of nutrition. Starting with the nutritional history of Homo sapiens, the author guides you into the fundamental interplay between proteins, fats, and carbohydrates, what they do in the body, how they are digested, and what role they really play. Supporting you will find in the second edition various retrievable videos in which complex relationships are clearly explained. This quickly shows how little is hidden behind some dubious statements. With the claim of a scientific and molecular view of nutrition, it is possible to put into perspective and classify many a questionable recommendation on nutrition in an understandable and entertaining way.

Biochemistry and Physiology of Nutrition, Volume II focuses on the processes, methods, and studies on nutrition. The book starts by discussing intracellular localization through histochemical methods of enzymes and vitamins; the structural changes in vitamin deficiency; and microbiology of digestion. Deficiencies in vitamins, A, C, D, E, B1, riboflavin, nicotinic acid, choline, biotin, and folic acid are noted. The book then focuses on microbiology of digestion, considering the establishment of microbial population in the alimentary tract, results of microbial digestion, antibiotics, and intestinal flora of man. The text also defines the nutrition system of worms, insects, and protozoa. The generation of ATP in terminal respiration and anaerobic glycolysis, as well as ATP's role in energy transfer, is noted. The discussions also focus on hydrolytic and phosphorylitic enzymes, such as carbohydrates, esterases, amidases, phosphatases, and phosporylases. Other topics covered are respiratory enzymes and coenzymes in which nucleotides, glucose diphosphate, diphosphoglyceric acid, and thiamine pyrophosphate are noted. The book notes the functions of iron compounds in the body, particularly in blood and tissues, and then touches on calcium and phosphorus metabolism. Given considerations are calcium and phosphorus in blood, skeletal calcium and phosphorus, and the factors affecting adsorption. A discussion also focuses on trace elements and the effects of protein, carbohydrates, fats, and vitamins in nutrition. The book is a vital source of data for readers interested in studying the elements, factors, processes, and methods involved in nutrition.

This exciting new book is the updated and revised second edition of an extremely popular and well-received textbook. Written by Martin Eastwood, well respected internationally in nutritional sciences, this important new edition provides students with a thorough book that should be adopted for course use on many courses worldwide. Taking into account constructive comments received by students and teachers who used and enjoyed the first edition, this new edition retains the original freshness of the 1st edition, looking at nutrition as an exciting discipline. Special features within the book to help students include summaries, boxes and questions. Carefully laid out to assist learning, the book is divided broadly into sections, providing in-depth coverage of the following subjects: food in the community metabolism of nutrients by an individual, dictated by genetic makeup, measurement of an individual’s nutritional status essential, non-essential and non-nutrients; their selection, ingestion, digestion, absorption and metabolism nutritional requirements in the normal individual and for specific diseases Principles of Human Nutrition, 2nd Edition is primarily written as a course text for those studying degree courses in nutrition and dietetics and for students on modular courses on nutrition within other degree courses, e.g. food studies, medicine, health sciences, nursing and biological sciences. It is also of great value as a reference for professional nutritionists and dietitians, food scientists and health professionals based in academia, in practice and in commercial positions such as within the food and pharmaceutical industries. Multiple copies of this valuable book should also be on the shelves of all universities, medical schools and research establishments where these subjects are studied and taught.

This volume contains the proceedings of the 2nd World Conference of the International Society for Molecular Nutrition & Therapy. This conference was held on August 2-4, 1997, in Winnipeg, Canada. The goal of the conference was to advance our knowledge concerning the molecular events which link nutrition to various disease processes in the body. This volume represents an important compilation of unique articles addressing the molecular and cellular basis for the nutritional and therapeutic treatment of five general disease processes.

The Brazilian Society of Nutrition, through the present public ation, brings to the attention of the world scientific community the works presented at the XI INTERNATIONAL CONGRESS OF NUTRITION which, promoted by this Society and under the sponsorship of the Interna tional Union of Nutritional Science, was held in the city of Rio de Janeiro from August 27th to September lst, 1978. The publication, edited by Plenum Publishing Corporation, is 11 titled Nutrition and Food Science: Presented Knowledge and Utiliza tion•• and appears in three volumes. under the following titles and sub-titles: Vol. I - FOOD AND NUTRITION POLICIES AND PROGRAMS - Planning and Implementation of National Programs - The role of International and Non-governmental Agencies - The role of the Private Sector -Program Evaluation and Nutritional Surveillance - Nutrition Intervention Programs for Rural and UrbanAreas - Mass Feeding Programs - Consumer Protection Programs Vol. I I -NUTRITION EDUCATION AND FOOD SCIENCE AND TECHNOLOGY - Animal and Vegetable Resources for Human Feeding - Food Science and Technology - Research in Food and Nutrition - Nutrition Education Vol. I I I -NUTRITIONAL BIOCHEMISlRY AND PATHOLOGY - Nutritional Biochemistry - Pathological and Chemical Nutrition - Nutrition, Growth and Human Development v vi FOREWORD It is hoped that this publication may prove useful to all those who are tnterested in the different aspects of Nutrition Science.

Introduction to Nutrition and Health Research aims to fill a critical gap in dietetics, nutrition and health education literature by providing a comprehensive guide to conducting research and understanding the research of others. Using actual articles, this book teaches how researchers identified problems; how they framed those problems; and how they reported, interpreted and implemented their findings. Step by step, the chapters cover an overview of the process, statistical and measurement concepts, types of research (including experimental, quasi-experimental, descriptive, and qualitative research), how to present results and computer techniques for data analysis. While this book is primarily aimed at masters and doctoral level students and beginning researchers, it will also have strong appeal for teachers, technicians and counselors.
