Total Diet Studies


Book Description

Unless a food is grossly contaminated, consumers are unable to detect through sight or smell the presence of low levels of toxic chemicals in their foods. Furthermore, the toxic effects of exposure to low levels of chemicals are often manifested slowly, sometimes for decades, as in the case of cancer or organ failure. As a result, safeguarding food from such hazards requires the constant monitoring of the food supply using sophisticated laboratory analysis. While the food industry bears the primary responsibility for assuring the safety of its products, the overall protection of people’s diets from chemical hazards must be considered one of the most important public health functions of any government. Unfortunately, many countries do not have sufficient capability and capacity to monitor the exposure of their populations to many potentially toxic chemicals that could be present in food and drinking water. Without such monitoring, public health authorities in many countries are not able to identify and respond to problems posed by toxic chemicals, which may harm their population and undermine consumer confidence in the safety of the food supply. From a trade perspective, those countries that cannot demonstrate that the food they produce is free of potentially hazardous chemicals will be greatly disadvantaged or even subject to sanctions in the international marketplace. The goal of a total diet study (TDS) is to provide basic information on the levels and trends of exposure to chemicals in foods as consumed by the population. In other words, foods are processed and prepared as typical for a country before they are analyzed in order to better represent actual dietary intakes. Total diet studies have been used to assess the safe use of agricultural chemicals (e.g., pesticides, antibiotics), food additives (e.g., preservatives, sweetening agents), environmental contaminants (e.g., lead, mercury, arsenic, cadmium, PCBs, dioxins), processing contaminants (e.g., acrylamide, polycyclic aromatic hydrocarbons, chloropropanols), and natural contaminants (e.g., aflatoxin, patulin, other mycotoxins) by determining whether dietary exposure to these chemicals are within acceptable limits. Total diet studies can also be applied to certain nutrients where the goal is to assure intakes are not only below safe upper limits, but also above levels deemed necessary to maintain good health. International and national organizations, such as the World Health Organization, the European Food Safety Agency and the US Food and Drug Administration recognize the TDS approach as one of the most cost-effective means of protecting consumers from chemicals in food, for providing essential information for managing food safety, including food standards, and for setting priorities for further investment and study. Total Diet Studies introduces the TDS concept to a wider audience and presents the various steps in the planning and implementation of a TDS. It illustrates how TDSs are being used to protect public health from chemicals in the food supply in many developed and developing countries. The book also examines some of the applications of TDSs to specific chemicals, including contaminants and nutrients.




Front-of-Package Nutrition Rating Systems and Symbols


Book Description

During the past decade, tremendous growth has occurred in the use of nutrition symbols and rating systems designed to summarize key nutritional aspects and characteristics of food products. These symbols and the systems that underlie them have become known as front-of-package (FOP) nutrition rating systems and symbols, even though the symbols themselves can be found anywhere on the front of a food package or on a retail shelf tag. Though not regulated and inconsistent in format, content, and criteria, FOP systems and symbols have the potential to provide useful guidance to consumers as well as maximize effectiveness. As a result, Congress directed the Centers for Disease Control and Prevention (CDC) to undertake a study with the Institute of Medicine (IOM) to examine and provide recommendations regarding FOP nutrition rating systems and symbols. The study was completed in two phases. Phase I focused primarily on the nutrition criteria underlying FOP systems. Phase II builds on the results of Phase I while focusing on aspects related to consumer understanding and behavior related to the development of a standardized FOP system. Front-of-Package Nutrition Rating Systems and Symbols focuses on Phase II of the study. The report addresses the potential benefits of a single, standardized front-label food guidance system regulated by the Food and Drug Administration, assesses which icons are most effective with consumer audiences, and considers the systems/icons that best promote health and how to maximize their use.

The China Study: Revised and Expanded Edition


Book Description

The revised and expanded edition of the bestseller that changed millions of lives The science is clear. The results are unmistakable. You can dramatically reduce your risk of cancer, heart disease, and diabetes just by changing your diet. More than 30 years ago, nutrition researcher T. Colin Campbell and his team at Cornell, in partnership with teams in China and England, embarked upon the China Study, the most comprehensive study ever undertaken of the relationship between diet and the risk of developing disease. What they found when combined with findings in Colin's laboratory, opened their eyes to the dangers of a diet high in animal protein and the unparalleled health benefits of a whole foods, plant-based diet. In 2005, Colin and his son Tom, now a physician, shared those findings with the world in The China Study, hailed as one of the most important books about diet and health ever written. Featuring brand new content, this heavily expanded edition of Colin and Tom's groundbreaking book includes the latest undeniable evidence of the power of a plant-based diet, plus updated information about the changing medical system and how patients stand to benefit from a surging interest in plant-based nutrition. The China Study—Revised and Expanded Edition presents a clear and concise message of hope as it dispels a multitude of health myths and misinformation. The basic message is clear. The key to a long, healthy life lies in three things: breakfast, lunch, and dinner.

Food Politics


Book Description

We all witness, in advertising and on supermarket shelves, the fierce competition for our food dollars. In this engrossing exposé, Marion Nestle goes behind the scenes to reveal how the competition really works and how it affects our health. The abundance of food in the United States--enough calories to meet the needs of every man, woman, and child twice over--has a downside. Our over-efficient food industry must do everything possible to persuade people to eat more--more food, more often, and in larger portions--no matter what it does to waistlines or well-being. Like manufacturing cigarettes or building weapons, making food is big business. Food companies in 2000 generated nearly $900 billion in sales. They have stakeholders to please, shareholders to satisfy, and government regulations to deal with. It is nevertheless shocking to learn precisely how food companies lobby officials, co-opt experts, and expand sales by marketing to children, members of minority groups, and people in developing countries. We learn that the food industry plays politics as well as or better than other industries, not least because so much of its activity takes place outside the public view. Editor of the 1988 Surgeon General's Report on Nutrition and Health, Nestle is uniquely qualified to lead us through the maze of food industry interests and influences. She vividly illustrates food politics in action: watered-down government dietary advice, schools pushing soft drinks, diet supplements promoted as if they were First Amendment rights. When it comes to the mass production and consumption of food, strategic decisions are driven by economics--not science, not common sense, and certainly not health. No wonder most of us are thoroughly confused about what to eat to stay healthy. An accessible and balanced account, Food Politics will forever change the way we respond to food industry marketing practices. By explaining how much the food industry influences government nutrition policies and how cleverly it links its interests to those of nutrition experts, this path-breaking book helps us understand more clearly than ever before what we eat and why.
