This book summarizes recent advances in the chemistry, bioactivity, nutrition, and functional aspects of dietary phytochemicals, as well as the health and functional aspects of foods rich in phytochemicals. Consisting of forty-four chapters, it discusses the different chemical types of phytochemicals in our diets and food and presents data collected from animal or human experiments that are directly related to human health. Each chapter covers the chemistry, epidemiological study, bioavailability, bioactivity (animal experiments) function in humans and safety, as well as products on the market. Moreover, the more than 200 figures make it easy to grasp the main findings in each area.
Plant foods are rich in micronutrients, but they also contain an immense variety of biologically-active, non-nutritive compounds that contribute to colour, flavour and other characteristics. This book assesses the health benefits of phytochemicals, as well as the functional benefits of particular groups of phytochemicals such as phytoestogens, carotenoids and flavonoids. It covers key safety and quality issues in developing phytochemical products, instituting appropriate intake levels, testing for safety and establishing health claims through clinical trials. This book will establish itself as a standard reference on one of the most important sectors in the functional foods market.
Nutraceuticals are bioactive phytochemicals that protect or promote health and occur at the intersection of food and pharmaceutical industries. This book will cover a wider spectrum of human health and diseases including the role of phytonutrients in the prevention and treatment. The Book includes chapters dealing with biological and clinical effect, molecular level approach, quality assurance, bioavailability and metabolism of a number phytochemicals and their role to combat different diseases.
The risk assessment approach described in this monograph applies only to essential trace elements (ETEs) involved in human health and not to non-essential elements. The purpose of this monograph is to provide the scientific principles that support the concept of an acceptable range of oral intake (AROI) which uses a homeostatic model for determining the range of dietary intakes for essential trace elements (ETEs) that meet the nutritional requirements of a healthy population and avoid excess intakes. To facilitate comparisons AROIs are discussed in relation to other risk assessment approaches. Although it includes examples this monograph is not a compendium of assessments on ETEs nor is it a textbook detailing the scientific basis of risk assessment of the derivation of dietary reference intakes. Described in the book is the process of risk assessment which begins with the selection of the database for a particular ETE. A weight-of-evidence approach is then used for hazard identification selecting relevant end-point of deficient and excess exposures. Next the probability of risk and the severity of various effects are quantified and critical effects are selected. The AROI is then established by balancing end-points of comparable health significance. At this time the exposure assessment is conducted. Finally a risk characterization enumerating the strengths and weaknesses of the databases is performed integrating the AROI and exposure assessment. ... The amount of work which is entailed in these volumes is very great and the low cost does not reflect the time of experts travelling nor even the hours expended UN staff in Geneva... This well informed book with its predecessors in the series is essential reading for biologists chemists and medical professionals concerned with essential trace elements. - The International Journal of Environmental Studies
The sixth annual research conference of the American Institute for Cancer Research was held August 31 and September 1, 1995, at the Loews L'Enfant Plaza Hotel in Washing ton, DC. In view of the promising leads in the diet/nutrition and cancer research field, the conference was devoted to "Dietary Phytochemicals in Cancer Prevention and Treatment. " The number of sessions was increased over that in previous conferences in order to accommodate the topics of interest. The conference overview, entitled "Plants and Cancer: Food, Fiber, and Phytochemicals," provided a framework for the following sessions. In addition, the attendees were reminded that for several decades epidemiologists have noted a lower risk of lung, esophageal, stomach, and colon cancer in populations consuming diets high in fruits and vegetables. However, isolation and ingestion of individual protective factors are not the preferred action since the complexity of the food and the matrix in which nutritional factors are embedded are important. The individual sessions then provided more insight as to why eating fruits and vegetables is associated with a lower risk of cancer. The first of these sessions was on "Isothiocyanates" that induce both the Phase I and Phase II enzymes that increase detoxification and conjugation reactions, thus causing more rapid removal of any xenobiotic or carcinogen. Thus, less carcinogen is available for interaction with DNA or other critical cellular macromolecules.
Despite increasing knowledge of human nutrition, the dietary contribution to cancer remains a troubling question. Carcinogens and Anticarcinogens assembles the best available information on the magnitude of potential cancer riskâ€"and potential anticarcinogenic effectâ€"from naturally occurring chemicals compared with risk from synthetic chemical constituents. The committee draws important conclusions about diet and cancer, including the carcinogenic role of excess calories and fat, the anticarcinogenic benefit of fiber and other substances, and the impact of food additive regulation. The book offers recommendations for epidemiological and diet research. Carcinogens and Anticarcinogens provides a readable overview of issues and addresses critical questions: Does diet contribute to an appreciable proportion of human cancer? Are there significant interactions between carcinogens and anticarcinogens in the diet? The volume discusses the mechanisms of carcinogenic and anticarcinogenic properties and considers whether techniques used to evaluate the carcinogenic potential of synthetics can be used with naturally occurring chemicals. The committee provides criteria for prioritizing the vast number of substances that need to be tested. Carcinogens and Anticarcinogens clarifies the issues and sets the direction for further investigations into diet and cancer. This volume will be of interest to anyone involved in food and health issues: policymakers, regulators, researchers, nutrition professionals, and health advocates.
Phytochemicals are plant derived chemicals which may bestow health benefits when consumed, whether medicinally or as part of a balanced diet. Given that plant foods are a major component of most diets worldwide, it is unsurprising that these foods represent the greatest source of phytochemicals for most people. Yet it is only relatively recently that due recognition has been given to the importance of phytochemicals in maintaining our health. New evidence for the role of specific plant food phytochemicals in protecting against the onset of diseases such as cancers and heart disease is continually being put forward. The increasing awareness of consumers of the link between diet and health has exponentially increased the number of scientific studies into the biological effects of these substances. The Handbook of Plant Food Phytochemicals provides a comprehensive overview of the occurrence, significance and factors effecting phytochemicals in plant foods. A key of objective of the book is to critically evaluate these aspects. Evaluation of the evidence for and against the quantifiable health benefits being imparted as expressed in terms of the reduction in the risk of disease conferred through the consumption of foods that are rich in phytochemicals. With world-leading editors and contributors, the Handbook of Plant Food Phytochemicals is an invaluable, cutting-edge resource for food scientists, nutritionists and plant biochemists. It covers the processing techniques aimed at the production of phytochemical-rich foods which can have a role in disease-prevention, making it ideal for both the food industry and those who are researching the health benefits of particular foods. Lecturers and advanced students will find it a helpful and readable guide to a constantly expanding subject area.
