Both fresh and processed foods make up vital parts of the food supply. Processed food contributes to both food security (ensuring that sufficient food is available) and nutrition security (ensuring ...that food quality meets human nutrient needs). This ASN scientific statement focuses on one aspect of processed foods: their nutritional impacts. Specifically, this scientific statement 1) provides an introduction to how processed foods contribute to the health of populations, 2) analyzes the contribution of processed foods to “nutrients to encourage” and “constituents to limit” in the American diet as recommended by the Dietary Guidelines for Americans, 3) identifies the responsibilities of various stakeholders in improving the American diet, and 4) reviews emerging technologies and the research needed for a better understanding of the role of processed foods in a healthy diet. Analyses of the NHANES 2003–2008 show that processed foods provide both nutrients to encourage and constituents to limit as specified in the 2010 Dietary Guidelines for Americans. Of the nutrients to encourage, processed foods contributed 55% of dietary fiber, 48% of calcium, 43% of potassium, 34% of vitamin D, 64% of iron, 65% of folate, and 46% of vitamin B-12. Of the constituents to limit, processed foods contributed 57% of energy, 52% of saturated fat, 75% of added sugars, and 57% of sodium. Diets are more likely to meet food guidance recommendations if nutrient-dense foods, either processed or not, are selected. Nutrition and food science professionals, the food industry, and other stakeholders can help to improve the diets of Americans by providing a nutritious food supply that is safe, enjoyable, affordable, and sustainable by communicating effectively and accurately with each other and by working together to improve the overall knowledge of consumers.
"As population estimates for 2050 reach over 9 billion, issues of food security and nutrition have been dominating academic and policy debates. A total of 805 million people are undernourished ...worldwide and malnutrition affects nearly every country on the planet. Despite impressive productivity increases, there is growing evidence that conventional agricultural strategies fall short of eliminating global hunger, as well as having long-term ecological consequences. Forests can play an important role in complementing agricultural production to address the Sustainable Development Goals on zero hunger. Forests and trees can be managed to provide better and more nutritionally-balanced diets, greater control over food inputs – particularly during lean seasons and periods of vulnerability (especially for marginalised groups) – and deliver ecosystem services for crop production. However forests are undergoing a rapid process of degradation, a complex process that governments are struggling to reverse. This volume provides important evidence and insights about the potential of forests to reducing global hunger and malnutrition, exploring the different roles of landscapes, and the governance approaches that are required for the equitable delivery of these benefits. Forests and Food is essential reading for researchers, students, NGOs and government departments responsible for agriculture, forestry, food security and poverty alleviation around the globe."
The focus of food science and technology has shifted from previous goals of improving food safety and enhancing food taste toward providing healthy and functional foods. Today's consumers desire ...foods that go beyond basic nutrition-foods capable of promoting better health, or even playing a disease- prevention role. To meet this need for innovation,
Food insecurity poses one of the most pressing development and human security challenges in the world. In Feeding the Hungry, MichelleJurkovich examines the social and normative environments in which ...international anti-hunger organizations are working and argues that despite international law ascribing responsibility to national governments to ensure the right to food of their citizens, there is no shared social consensus on who ought to do what to solve the hunger problem. Drawing on interviews with staff at top international anti-hunger organizations aswell as archival research at the United Nations Food and Agriculture Organization, the UK National Archives, and the U.S. National Archives, Jurkovich provides a new analytic model of transnational advocacy. In investigating advocacy around a critical economic and social right—the right to food—Jurkovich challenges existing understandings of the relationships among human rights, norms, and laws. Most important, Feeding the Hungry provides an expanded conceptual tool kit with which we can examine and understand the social and moral forces at play in rights advocacy.
Nanotechnology has underpinned vital progress in current research and has immensely promoted the food production chain. This review projected the critical intervention of nano-based technologies like ...modern advancements of nano-based biosensors in detecting mycotoxins, microbial contaminations, antibiotics, pesticides, food additives, and dyes. It also highlighted the starring roles of nanotechnology in terms of active, intelligent food packaging and food safety. These approaches have certainly intensified the strength of food processing technology and improved food quality and maintenance standards during shelf life. Apart from these trending facets, this review throw light on the utilisation of food waste for the biogenic synthesis of nanoparticles and the application of nano-based materials for the recycling process in food production units to ensure a complete cleaner technology. However, monitoring the chronic exposure of food contact nanomaterials should be critically evaluated to ensure food safety. Nanotechnology embraced an influential role in the food sector by providing effective avenues for energy conservation, sustainability, and cues to improve the capital funds well.

Foreigners and Their Food explores how Jews, Christians, and Muslims conceptualize "us" and "them" through rules about the preparation of food by adherents of other religions and the act of eating ...with such outsiders. David M. Freidenreich analyzes the significance of food to religious formation, elucidating the ways ancient and medieval scholars use food restrictions to think about the "other." Freidenreich illuminates the subtly different ways Jews, Christians, and Muslims perceive themselves, and he demonstrates how these distinctive self-conceptions shape ideas about religious foreigners and communal boundaries. This work, the first to analyze change over time across the legal literatures of Judaism, Christianity, and Islam, makes pathbreaking contributions to the history of interreligious intolerance and to the comparative study of religion.
Minimally processed fruits and vegetables are one of the major growing sectors in food industry. This growing demand for healthy and convenient foods with fresh-like properties is accompanied by ...concerns surrounding efficacy of the available sanitizing methods to appropriately deal with food-borne diseases. In fact, chemical sanitizers do not provide an efficient microbial reduction, besides being perceived negatively by the consumers, dangerous for human health, and harmful to the environment, and the conventional thermal treatments may negatively affect physical, nutritional, or bioactive properties of these perishable foods. For these reasons, the industry is investigating alternative nonthermal physical technologies, namely innovative packaging systems, ionizing and ultraviolet radiation, pulsed light, high-power ultrasound, cold plasma, high hydrostatic pressure, and dense phase carbon dioxide, as well as possible combinations between them or with other preservation factors (hurdles). This review discusses the potential of these novel or emerging technologies for decontamination and shelf-life extension of fresh and minimally processed fruits and vegetables. Advantages, limitations, and challenges related to its use in this sector are also highlighted.
The rapid development of nanotechnology has transformed many domains of food science, especially those that involve the processing, packaging, storage, transportation, functionality, and other safety ...aspects of food. A wide range of nanostructured materials (NSMs), from inorganic metal, metal oxides, and their nanocomposites to nano-organic materials with bioactive agents, has been applied to the food industry. Despite the huge benefits nanotechnology has to offer, there are emerging concerns regarding the use of nanotechnology, as the accumulation of NSMs in human bodies and in the environment can cause several health and safety hazards. Therefore, safety and health concerns as well as regulatory policies must be considered while manufacturing, processing, intelligently and actively packaging, and consuming nano-processed food products. This review aims to provide a basic understanding regarding the applications of nanotechnology in the food packaging and processing industries and to identify the future prospects and potential risks associated with the use of NSMs.
