  beta carotene lung cancer study flawed: Eat for Life National Academy of Sciences, Institute of Medicine, 1992-01-01 Results from the National Research Council's (NRC) landmark study Diet and health are readily accessible to nonscientists in this friendly, easy-to-read guide. Readers will find the heart of the book in the first chapter: the Food and Nutrition Board's nine-point dietary plan to reduce the risk of diet-related chronic illness. The nine points are presented as sensible guidelines that are easy to follow on a daily basis, without complicated measuring or calculatingâ€and without sacrificing favorite foods. Eat for Life gives practical recommendations on foods to eat and in a how-to section provides tips on shopping (how to read food labels), cooking (how to turn a high-fat dish into a low-fat one), and eating out (how to read a menu with nutrition in mind). The volume explains what protein, fiber, cholesterol, and fats are and what foods contain them, and tells readers how to reduce their risk of chronic disease by modifying the types of food they eat. Each chronic disease is clearly defined, with information provided on its prevalence in the United States. Written for everyone concerned about how they can influence their health by what they eat, Eat for Life offers potentially lifesaving information in an understandable and persuasive way.

  beta carotene lung cancer study flawed: How Tobacco Smoke Causes Disease United States. Public Health Service. Office of the Surgeon General, 2010 This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
  beta carotene lung cancer study flawed: Carcinogens and Anticarcinogens in the Human Diet National Research Council, Division on Earth and Life Studies, Commission on Life Sciences, Committee on Comparative Toxicity of Naturally Occurring Carcinogens, 1996-03-12 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.
  beta carotene lung cancer study flawed: The Health Consequences of Involuntary Exposure to Tobacco Smoke , 2006 This Surgeon General's report returns to the topic of the health effects of involuntary exposure to tobacco smoke. The last comprehensive review of this evidence by the Department of Health and Human Services (DHHS) was in the 1986 Surgeon General's report, The Health Consequences of Involuntary Smoking, published 20 years ago this year. This new report updates the evidence of the harmful effects of involuntary exposure to tobacco smoke. This large body of research findings is captured in an accompanying dynamic database that profiles key epidemiologic findings, and allows the evidence on health effects of exposure to tobacco smoke to be synthesized and updated (following the format of the 2004 report, The Health Consequences of Smoking). The database enables users to explore the data and studies supporting the conclusions in the report. The database is available on the Web site of the Centers for Disease Control and Prevention (CDC) at http://www.cdc.gov/tobacco.

  beta carotene lung cancer study flawed: The Fat-Soluble Vitamins H. DeLuca, 2012-12-06 The first demonstration of the existence of a vitamin and the full recognition of this fact are often attributed to the work of McCollum, who found that a sub stance in butterfat and cod-liver oil was necessary for growth and health of ani mals fed purified diets. It became obvious that an organic substance present in microconcentrations was vital to growth and reproduction of animals. Following the coining of the word vitamine by Funk, McCollum named this fat-soluble sub stance vitamin A. We can, therefore, state that vitamin A was certainly one of the first known vitamins, yet its function and the function of the other fat-soluble vitamins had remained largely unknown until recent years. However, there has been an explosion of investigation and new information in this field, which had remained quiescent for at least two or three decades. It is now obvious that the fat-soluble vitamins function quite differently from their water-soluble counter parts. We have learned that vitamin D functions by virtue of its being converted in the kidney to a hormone that functions to regulate calcium and phosphorus metabolism. This new endocrine system is in the process of being elucidated in detail, and in addition, the medical use of these hormonal forms of vitamin D in the treatment of a variety of metabolic bone diseases has excited the medical com munity.
  beta carotene lung cancer study flawed: Diet and Health National Research Council, Division on Earth and Life Studies, Commission on Life Sciences, Committee on Diet and Health, 1989-01-01 Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.
  beta carotene lung cancer study flawed: Nutraceuticals and Cancer Signaling Seid Mahdi Jafari, Seyed Mohammad Nabavi, Ana Sanches Silva, 2021-09-24 Today's consumers are looking for food products with health-promoting roles in addition to nutritional benefits. With current research showing that nutraceuticals and functional foods rich in specific bioactives may have chemopreventative effects, these products are increasingly popular. However, while much in the literature supports the health-promoting features of these foods, few texts focus on their bioactive agents and their mode of action in cancer signaling. Nutraceuticals and Cancer Signalling: Clinical Aspects and Mode of Action explains the link between nutraceuticals and cancer in terms of clinical trials and modes of action. This book gives an overview of common cancers and their mechanisms, and the most common functional foods and their bioactive components. Individual chapters focus on specific functional foods--including tomatoes, garlic, honey, tea, yoghurt, and many more--their prominent bioactive compounds, and their mode of action in cancer signaling and chemoprevention. Recent findings on cancer-prevention roles of different vitamins and minerals are also discussed. For food scientists, nutritionists, and pharmaceutical experts looking to understand how functional foods can play a role in fighting cancer, this text serves as a one-stop reference.
  beta carotene lung cancer study flawed: Cancer Epidemiology Isabel dos Santos Silva, International Agency for Research on Cancer, 1999 A basic textbook addressed to medical and public health students, clinicians, health professionals, and all others seeking to understand the principles and methods used in cancer epidemiology. Written by a prominent epidemiologist and experienced teacher at the London School of Hygiene and Tropical Medicine, the text aims to help readers become competent in the use of basic epidemiological tools and capable of exercising critical judgment when assessing results reported by others. Throughout the text, a lively writing style and numerous illustrative examples, often using real research data, facilitate an easy understanding of basic concepts and methods. Information ranges from an entertaining account of the origins of epidemiology, through advice on how to overcome some of the limitations of survival analysis, to a checklist of questions to ask when considering sources of bias. Although statistical concepts and formulae are presented, the emphasis is consistently on the interpretation of the data rather than on the actual calculations. The text has 18 chapters. The first six introduce the basic principles of epidemiology and statistics. Chapters 7-13 deal in more depth with each of the study designs and interpretation of their findings. Two chapters, concerned with the problems of confounding and study size, cover more complex statistical concepts and are included for advanced study. A chapter on methodological issues in cancer prevention gives examples of epidemiology's contribution to primary prevention, screening and other activities for early detection, and tertiary prevention. The concluding chapters review the role of cancer registries and discuss practical considerations that should be taken into account in the design, planning, and conduct of any type of epidemiological research.

  beta carotene lung cancer study flawed: Functional Foods in Cancer Prevention and Therapy Yearul Kabir, 2020-03-24 Functional Foods in Cancer Prevention and Therapy presents the wide range of functional foods associated with the prevention and treatment of cancer. In recent decades, researchers have made progress in our understanding of the association between functional food and cancer, especially as it relates to cancer treatment and prevention. Specifically, substantial evidence from epidemiological, clinical and laboratory studies show that various food components may alter cancer risk, the prognosis after cancer onset, and the quality of life after cancer treatment. The book documents the therapeutic roles of well-known functional foods and explains their role in cancer therapy. The book presents complex cancer patterns and evidence of the effective ways to control cancers with the use of functional foods. This book will serve as informative reference for researchers focused on the role of food in cancer prevention and physicians and clinicians involved in cancer treatment.

  beta carotene lung cancer study flawed: Red Meat and Processed Meat IARC Working Group on the Evaluation of Carcinogenic Risks to Humans, International Agency for Research on Cancer, 2018-07-27 This volume of the IARC Monographs provides evaluations of the consumption of red meat and the consumption of processed meat. Red meat refers to unprocessed mammalian muscle meat (e.g. beef, veal, pork, lamb) including that which may be minced or frozen. Processed meat refers to meat that has been transformed through salting, curing, fermentation, smoking or other processes to enhance flavor or improve preservation. Most processed meats contain pork or beef, but may also contain other meats including poultry and offal (e.g. liver) or meat by-products such as blood. Red meat contains proteins of high biological value, and important micronutrients such as B vitamins, iron (both free iron and haem iron), and zinc. Carcinogens, including heterocyclic aromatic amines and polycyclic aromatic hydrocarbons, can be produced by cooking of meat, with greatest amounts generated at high temperatures by pan-frying, grilling, or barbecuing. Meat processing such as curing and smoking can result in formation of carcinogenic chemicals including N-nitroso compounds and polycyclic aromatic hydrocarbons. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of the consumption of red meat and processed meat. The Working Group assessed more than 800 epidemiological studies that investigated the association of cancer (more than 15 types) with consumption of red meat or processed meat, including large cohorts in many countries, from several continents, with diverse ethnicities and diets.
  beta carotene lung cancer study flawed: Flavonoids José Justino, 2017-08-23 Flavonoids are abundant secondary metabolites found in plants and fungi that have various roles in these organisms, including pigmentation, cell signalling, plant defence and inter-organism communication. Due to their abundance in nature, flavonoids are also important components of the human diet, and the last four decades have seen an intense study focused on the structure characterization of flavonoids and on their roles in mammal metabolism. This book reviews most of the well-established activities of flavonoids, and we also present more recent research studies on the area of flavonoids, including the chemical aspects of structure characterization of flavonoids, the biosynthesis of flavonoids in model plants as well as their role in abiotic stress situations and in agriculture, the role of flavonoids in metabolism and health and their importance in foods, from consumption to their use as bioactive components.

  beta carotene lung cancer study flawed: Vitamania Catherine Price, 2015-02-24 “[An] absorbing and meticulously researched history of the beginnings and causes of our obsession with vitamins and nutrition.” —The New York Times Most of us know nothing about vitamins. What’s more, what we think we know is harming both our personal nutrition and our national health. By focusing on vitamins at the expense of everything else, we’ve become blind to the bigger picture: despite our belief that vitamins are an absolute good—and the more of them, the better—vitamins are actually small and surprisingly mysterious pieces of a much larger nutritional puzzle. In Vitamania, award-winning journalist Catherine Price offers a lucid and lively journey through our cherished yet misguided beliefs about vitamins, and reveals a straightforward, blessedly anxiety-free path to enjoyable eating and good health. When vitamins were discovered a mere century ago, they changed the destiny of the human species by preventing and curing many terrifying diseases. Yet it wasn’t long before vitamins spread from labs of scientists into the realm of food marketers and began to take on a life of their own. The era of “vitamania,” as one 1940s journalist called it, had begun. Though we’ve gained much from our embrace of vitamins, what we’ve lost is a crucial sense of perspective. By buying into a century of hype and advertising, we have accepted the false idea that particular dietary chemicals can be used as shortcuts to health—whether they be antioxidants or omega-3s or, yes, vitamins. And it’s our vitamin-inspired desire for effortless shortcuts that created today’s dietary supplement industry, a veritable Wild West of overpromising “miracle” substances that can be legally sold without any proof that they are effective or safe. Price’s travels to vitamin manufacturers and food laboratories and military testing kitchens—along with her deep dive into the history of nutritional science— provide a witty and dynamic narrative arc that binds Vitamania together. The result is a page-turning exploration of the history, science, hype, and future of nutrition. And her ultimate message is both inspiring and straightforward: given all that we don’t know about vitamins and nutrition, the best way to decide what to eat is to stop obsessing and simply embrace this uncertainty head-on. Praise for Vitamania: “Measured, funny, and fascinating. The only thing that Catherine Price is selling here is good reporting, engaging storytelling, and more than you thought you could possibly learn about vitamins. If you need vitamins to survive (you do), you should read this book.” —Scientific American

  beta carotene lung cancer study flawed: Prostate Cancer Prevention Jack Cuzick, Mangesh A. Thorat, 2014-02-15 Prostate cancer is by far the most common cancer in men and the second leading cause of death due to cancer. It comprises a mixed group of tumours displaying varying clinical behaviour: while some have a very aggressive course, others are rather indolent. Prevention of prostate cancer and discrimination between aggressive and indolent forms are important clinical goals and the acquisition of significant new evidence on means of achieving these aims makes this book particularly timely. A wide range of topics are covered by leading authorities in the field. The biology and natural history of prostate cancer are reviewed and the role of lifestyle and dietary factors, assessed. Detailed attention is paid to risk prediction biomarkers and to the role of novel high-throughput nucleic acid-based technologies in improving risk prediction and thereby allowing tailored approaches to cancer prevention. Potential means of chemoprevention of prostate cancer are also reviewed in depth, covering the very positive new data on the impact of aspirin as well as evidence regarding 5α-reductase inhibitors, DFMO and lycopene. Guidance is provided on the differentiation of aggressive from indolent disease and the policy and research implications of recent findings are examined. This book will be of interest to both clinicians and researchers.

  beta carotene lung cancer study flawed: The Cancer Code Dr. Jason Fung, 2020-11-10 Author of the international bestsellers The Diabetes Code and The Obesity Code Dr. Jason Fung returns with an eye-opening biography of cancer in which he offers a radical new paradigm for understanding cancer—and issues a call to action for reducing risk moving forward. Our understanding of cancer is slowly undergoing a revolution, allowing for the development of more effective treatments. For the first time ever, the death rate from cancer is showing a steady decline . . . but the “War on Cancer” has hardly been won. In The Cancer Code, Dr. Jason Fung offers a revolutionary new understanding of this invasive, often fatal disease—what it is, how it manifests, and why it is so challenging to treat. In this rousing narrative, Dr. Fung identifies the medical community’s many missteps in cancer research—in particular, its focus on genetics, or what he terms the “seed” of cancer, at the expense of examining the “soil,” or the conditions under which cancer flourishes. Dr. Fung—whose groundbreaking work in the treatment of obesity and diabetes has won him international acclaim—suggests that the primary disease pathway of cancer is caused by the dysregulation of insulin. In fact, obesity and type 2 diabetes significantly increase an individual’s risk of cancer. In this accessible read, Dr. Fung provides a new paradigm for dealing with cancer, with recommendations for what we can do to create a hostile soil for this dangerous seed. One such strategy is intermittent fasting, which reduces blood glucose, lowering insulin levels. Another, eliminating intake of insulin-stimulating foods, such as sugar and refined carbohydrates. For hundreds of years, cancer has been portrayed as a foreign invader we’ve been powerless to stop. By reshaping our view of cancer as an internal uprising of our own healthy cells, we can begin to take back control. The seed of cancer may exist in all of us, but the power to change the soil is in our hands.
