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

Drawing on a variety of case studies, this book explores the interrelationship between physical connections to and knowledge of food. This book inserts into the food literature living, feeling, ...sensing bodies and will be of interest to food scholars as well as those more generally interested in the phenomenon known as embodied realism.
Radio frequency identification (RFID) is an alternative technology with a potential to replace traditional universal product code (UPC) barcodes. RFID enables identification of an object from a ...distance without requiring a line of sight. RFID tags can also incorporate additional data such as details of product and manufacturer and can transmit measured environmental factors such as temperature and relative humidity. This article presents key concepts and terminology related to RFID technology and its applications in the food industry. Components and working principles of an RFID system are described. Numerous applications of RFID technology in the food industry (supply chain management, temperature monitoring of foods, and ensuring food safety) are discussed. Challenges in implementation of RFID technology are also discussed in terms of read range, read accuracy, nonuniform standards, cost, recycling issues, privacy, and security concerns.
Why are people getting fatter in the United States and beyond? Mainstream explanations argue that people simply eat too much “energy-dense" food while exercising too little. By swapping the chips and ...sodas for fruits and vegetables and exercising more, the problem would be solved. By contrast, The Neoliberal Diet argues that increased obesity does not result merely from individual food and lifestyle choices. Since the 1980s, the neoliberal turn in policy and practice has promoted trade liberalization and retrenchment of the welfare regime, along with continued agricultural subsidies in rich countries. Neoliberal regulation has enabled agribusiness multinationals to thrive by selling highly processed foods loaded with refined flour and sugars—a diet that originated in the United States—as well as meat. Drawing on extensive empirical data, Gerardo Otero identifies the socioeconomic and political forces that created this diet, which has been exported around the globe, often at the expense of people’s health. Otero shows how state-level actions, particularly subsidies for big farms and agribusiness, have ensured the dominance of processed foods and made healthful fresh foods inaccessible to many. Comparing agrifood performance across several nations, including the NAFTA region, and correlating food access to class inequality, he convincingly demonstrates the structural character of food production and the effect of inequality on individual food choices. Resolving the global obesity crisis, Otero concludes, lies not in blaming individuals but in creating state-level programs to reduce inequality and make healthier food accessible to all.
All people involved with preparation of food for the commercial or retail market need a sound understanding of the food safety risks associated with their specific products and, importantly, how to ...control these risks. Failure to control food safety hazards can have devastating consequences for not only the consumer, but also the food manufacturer. This book provides practical guidance on how to control food safety hazards, with a specific focus on controls suitable for small-scale businesses to implement. Small businesses make up around two-thirds of businesses in Australia's food and beverage manufacturing industry. This book is aimed at those small-scale businesses already in or considering entering food manufacture. Those already operating a small business will develop a better understanding of key food safety systems, while those who are in the 'start-up' phase will gain knowledge essential to provide their business with a solid food safety foundation while also learning about Australian food regulations relevant to food safety.
Next Generation Sequencing (NGS) combined with powerful bioinformatic approaches are revolutionising food microbiology. Whole genome sequencing (WGS) of single isolates allows the most detailed ...comparison possible hitherto of individual strains. The two principle approaches for strain discrimination, single nucleotide polymorphism (SNP) analysis and genomic multi-locus sequence typing (MLST) are showing concordant results for phylogenetic clustering and are complementary to each other. Metabarcoding and metagenomics, applied to total DNA isolated from either food materials or the production environment, allows the identification of complete microbial populations. Metagenomics identifies the entire gene content and when coupled to transcriptomics or proteomics, allows the identification of functional capacity and biochemical activity of microbial populations.
The focus of this review is on the recent use and future potential of NGS in food microbiology and on current challenges. Guidance is provided for new users, such as public health departments and the food industry, on the implementation of NGS and how to critically interpret results and place them in a broader context. The review aims to promote the broader application of NGS technologies within the food industry as well as highlight knowledge gaps and novel applications of NGS with the aim of driving future research and increasing food safety outputs from its wider use.
•Advances in sequencing technologies and bioinformatics are ushering in rapid changes in food microbiology.•SNP and genomic MLST based WGS analyses for strain discrimination are complementary to each other.•In source tracking investigations, WGS results must be backed up by epidemiological and other investigative evidence.•Metabarcoding identifies complete microbial populations; metagenomics also determines hypothetical functional repertoire.•Harmonisation and standardisation has to be addressed and data sharing incentivised.
In this book, Ashante M. Reese makes clear the structural forces that determine food access in urban areas, highlighting Black residents' navigation of and resistance to unequal food distribution ...systems. Linking these local food issues to the national problem of systemic racism, Reese examines the history of the majority-Black Deanwood neighborhood of Washington, D.C. Based on extensive ethnographic fieldwork, Reese not only documents racism and residential segregation in the nation's capital but also tracks the ways transnational food corporations have shaped food availability. By connecting community members' stories to the larger issues of racism and gentrification, Reese shows there are hundreds of Deanwoods across the country. Reese's geographies of self-reliance offer an alternative to models that depict Black residents as lacking agency, demonstrating how an ethnographically grounded study can locate and amplify nuances in how Black life unfolds within the context of unequal food access.
Aims
The concept of using specific dietary components to selectively modulate the gut microbiota to confer a health benefit, defined as prebiotics, originated in 1995. In 2018, a group of scientists ...met at the International Scientific Association for Probiotics and Prebiotics annual meeting in Singapore to discuss advances in the prebiotic field, focussing on issues affecting functionality, research methodology and geographical differences.
Methods and Results
The discussion ranged from examining scientific literature supporting the efficacy of established prebiotics, to the prospects for establishing health benefits associated with novel compounds, isolated from different sources.
Conclusions
While many promising candidate prebiotics from across the globe have been highlighted in preliminary research, there are a limited number with both demonstrated mechanism of action and defined health benefits as required to meet the prebiotic definition. Prebiotics are part of a food industry with increasing market sales, yet there are great disparities in regulations in different countries. Identification and commercialization of new prebiotics with unique health benefits means that regulation must improve and remain up‐to‐date so as not to risk stifling research with potential health benefits for humans and other animals.
Significance and Impact of Study
This summary of the workshop discussions indicates potential avenues for expanding the range of prebiotic substrates, delivery methods to enhance health benefits for the end consumer and guidance to better elucidate their activities in human studies.
The production of drugs, cosmetics, and food which are derived from plant cell and tissue cultures has a long tradition. The emerging trend of manufacturing cosmetics and food products in a natural ...and sustainable manner has brought a new wave in plant cell culture technology over the past 10 years. More than 50 products based on extracts from plant cell cultures have made their way into the cosmetics industry during this time, whereby the majority is produced with plant cell suspension cultures. In addition, the first plant cell culture-based food supplement ingredients, such as Echigena Plus and Teoside 10, are now produced at production scale. In this mini review, we discuss the reasons for and the characteristics as well as the challenges of plant cell culture-based productions for the cosmetics and food industries. It focuses on the current state of the art in this field. In addition, two examples of the latest developments in plant cell culture-based food production are presented, that is, superfood which boosts health and food that can be produced in the lab or at home.
