This book was released on 2006 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel food regulation is already in force in the European Community, Australia/New Zealand and in Canada. These regulations distinguish between traditional plant foods and novel plant foods, as the novel plant foods need to go through a premarket assessment procedure. This report focus on developing a proposal for definitions and criteria for determining if a plant food is traditional or novel and a proposal for an approach for the safety assessment of such plant foods with no or limited documented history of safe consumption. The report recommend to introduce a 2-step management procedure, first to establish the novelty and secondly to define and commit resources for the safety assessment, and recommend to generate and use a worldwide net of global, regional, local and ethnobotanical positive lists for food plants to guide both the decision on novelty and the safety assessment. The report recommends using the "history of use"--Concept and if the data submitted can support the claim that a product has a history of safe use, the approval can be straightforward. In Europe around 300 food plants deliver near 100% of human daily intake of plant food calories while nearly 7,000 other food plant species are used in other parts of the world. This report focuses on the situation when novel food items from these 7,000 plants are to enter the European or other regional market.

Available in PDF, EPUB and Kindle. Book excerpt: Phytochemists are aware that their focus of interest is receiving attention from a wider segment of society and from a greater diversity of disciplines within the scientific community than ever before. Nonetheless, they were bemused to learn three years ago that "until recently scientists didn't even know phytochemi cals existed" (Newsweek, April 24, 1994). Changing public perception of the positive contributions of phytochemicals to human well-being has foundations in scientific advances. With popular reports emphasizing the important implica tions of phytochemicals in the daily lives of people, there is a pressing need for those working in this area to explain their diverse scientific activities to the public. Chemicals from plant foods are linked through epidemiological and ex perimental studies with reduced incidence of chronic degenerative diseases. Phytomedicines, standardized according to particular constituents, are making increasing contributions to health care. Naturally occurring constituents of plants are recognized as fundamental to the appeal, quality, and marketability of food products. In light of such developments, perceptions by phytochemists of their own discipline and its applications are expanding. Until recently, food phyto chemistry largely implied food toxicants. Food plants were familiar, but seldom the source of novel economically important compounds. Increasingly sophisti cated methods of analysis, however, have opened new opportunities for under standing the nature and functions offood constituents, and for manipulating them to improve the quality, acceptability, and value of food products.

Download or read book Fruit and Vegetables written by IARC Working Group on the Evaluation of Cancer-Preventive Strategies and published by IARC. This book was released on 2003 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook shows that approximately one in ten cancers in western populations is due to an insufficient intake of fruit and vegetables, a finding that should encourage all organizations as well as governments to continue efforts to increase or maintain fruit and vegetable intake as an important objective of programs to improve nutrition to reduce the burden of cancer and other chronic diseases. The clearest evidence of a cancer-protective effect of eating more fruits is for stomach and esophageal cancers. Similarly, a higher intake of vegetables probably reduces the incidence of cancer of esophagus and colon-rectum. Fruit and vegetables contain many nutrients; they also contain other bioactive compounds that may influence many aspects of human biology and related disease processes.

Download or read book Dietary Phytochemicals in Cancer Prevention and Treatment written by American Institute for Cancer Research and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Biomarkers of Phytochemical Intake in Human Trials Focusing on Modifiable Dietary Behaviors written by Emily B. Hill and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A plant-based dietary pattern is associated with improved health outcomes and is integrated within guidelines to promote public and individual health, such as the Dietary Guidelines for Americans (DGA) and the WCRF/AICR Cancer Prevention Guidelines. The number of cancer survivors has increased dramatically, and efforts are focusing upon promoting healthy survivorship free of cancer and enhancing longevity. Data suggests that diets of cancer survivors are inadequate in plant foods including fruits, vegetables, and whole grains. There is a critical need for studies focusing upon improving survivor dietary patterns. The development and validation of tools to assess the complex dietary intake of humans and biomarkers of exposure are crucial to this effort. Further, assessment of individual response to dietary intake remains complex and impacted by interacting components in the diet as well as genetic influences on digestion, absorption, and metabolism. Aligning dietary intake data with biomarkers of individual exposure and metabolism is critical for advancing knowledge. The goals of these studies were to explore select phytochemicals as biomarkers of dietary exposure within human trials by: (a) Defining changes in carotenoid status as an indicator of overall exposure to fruits and vegetables following an intervention with a healthy dietary pattern in free living cancer survivors; (b) Developing, evaluating, and validating a targeted LCMS flavonoid profile in 24-hour urine that is reflective of human intake and exposure to (poly)phenol-rich fruits and vegetables; and (c) Examining the relationships between a targeted (poly)phenol profile in the urine and/or dietary patterns and indicators of cardiometabolic health in a clinical trial of a healthy dietary pattern in cancer survivors. To achieve these goals, we conducted a clinical trial in cancer survivors (n=80) with overweight/obesity. Individuals enrolled in a lifestyle intervention with a primary goal of improving modifiable dietary behaviors to increase adherence to evidence-based dietary patterns (DGA and WCRF/AICR). Assessments were completed at enrollment, post-intervention (6 months), and post-maintenance (12 months) and included dietary intakes, anthropometrics, clinical outcomes, and plasma and 24-hour urine collection. We observed that plasma and skin carotenoids are strongly associated with improved dietary intakes of carotenoid-rich foods over weeks and months following intervention and improvements were maintained over time. Urinary (poly)phenol metabolites are a strong indicator of recent consumption, over multiple days, of foods rich in a diverse array of (poly)phenols. Together, data suggest that the multifaceted intervention led to greater intakes of plant-based foods and increases in diet quality, supported by concomitant increases in carotenoid and (poly)phenol exposure. We observed that implementation of a healthy dietary pattern and parallel improvements in biomarkers of carotenoid and (poly)phenol exposure are associated with successful weight loss, improved dietary indices, and other biomarkers of health. Patterns of blood and urinary metabolites of phytochemicals can provide a biomarker signature reflective of consumption patterns coupled with individual absorptive and metabolic capacity and may provide insight into how specific dietary changes may uniquely impact an individual and their health outcomes. In summary, these studies demonstrate the utility of an intense lifestyle intervention to improve dietary patterns and specific biomarkers of fruit and vegetable intake. The application of LCMS analysis of phytochemical profiles in blood and urine are useful tools predictive of intake of specific plant foods and provide insight into individual response. Such efforts will be useful in future randomized controlled clinical trials and metabolic epidemiologic studies to define relationships between foods and health.
