Available in PDF, EPUB and Kindle. Book excerpt: La toxicología alimentaria es una disciplina que reclama, cada vez más, la atención de investigadores y autoridades académicas, legislativas y gubernativas. El hombre ha debido aprender por experiencia propia, a veces dolorosa, a distinguir entre alimentos saludables y nocivos y, a lo largo de los siglos, a producir, conservar y preparar sus alimentos de la forma más beneficiosa. Pero el crecimiento de la población, la industrialización, la comercialización a gran escala, el mercantilismo, la no observancia de las legislaciones, etc., ha permitido la aparición de brotes e incluso de epidemias tóxicas de origen alimentario con cientos y hasta miles de intoxicados agudos, además de los incontables de carácter crónico, que son los que los alimentos pueden producir en mayor cantidad y de forma más solapada.

This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Synopsis Arsenic in Drinking Water by : National Research Council
Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-12-26 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.
Book Synopsis Cradle to Cradle by : William McDonough
Download or read book Cradle to Cradle written by William McDonough and published by North Point Press. This book was released on 2010-03-01 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: A manifesto for a radically different philosophy and practice of manufacture and environmentalism "Reduce, reuse, recycle" urge environmentalists; in other words, do more with less in order to minimize damage. But as this provocative, visionary book argues, this approach perpetuates a one-way, "cradle to grave" manufacturing model that dates to the Industrial Revolution and casts off as much as 90 percent of the materials it uses as waste, much of it toxic. Why not challenge the notion that human industry must inevitably damage the natural world? In fact, why not take nature itself as our model? A tree produces thousands of blossoms in order to create another tree, yet we do not consider its abundance wasteful but safe, beautiful, and highly effective; hence, "waste equals food" is the first principle the book sets forth. Products might be designed so that, after their useful life, they provide nourishment for something new-either as "biological nutrients" that safely re-enter the environment or as "technical nutrients" that circulate within closed-loop industrial cycles, without being "downcycled" into low-grade uses (as most "recyclables" now are). Elaborating their principles from experience (re)designing everything from carpeting to corporate campuses, William McDonough and Michael Braungart make an exciting and viable case for change.
Download or read book Severe Asthma written by Kian Fan Chung and published by European Respiratory Society. This book was released on 2019-06-01 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Severe asthma is a form of asthma that responds poorly to currently available medication, and its patients represent those with greatest unmet needs. In the last 10 years, substantial progress has been made in terms of understanding some of the mechanisms that drive severe asthma; there have also been concomitant advances in the recognition of specific molecular phenotypes. This ERS Monograph covers all aspects of severe asthma – epidemiology, diagnosis, mechanisms, treatment and management – but has a particular focus on recent understanding of mechanistic heterogeneity based on an analytic approach using various ‘omics platforms applied to clinically well-defined asthma cohorts. How these advances have led to improved management targets is also emphasised. This book brings together the clinical and scientific expertise of those from around the world who are collaborating to solve the problem of severe asthma.

Book Synopsis Mini Nutritional Assessment (MNA) by : Bruno J. Vellas
Download or read book Mini Nutritional Assessment (MNA) written by Bruno J. Vellas and published by Karger Medical and Scientific Publishers. This book was released on 1999 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of a new series which will present the proceedings of the newly established Nestlé Nutrition Workshop Series: Clinical & Performance Programme aimed at adult nutrition. Undernutrition is a common phenomenon in elderly people, and malnutrition reaches significant levels in those being in hospital, nursing homes or home care programs. Consequences of malnutrition often go unrecognised owing to the lack of specific validated instruments to assess nutritional status in frail elderly persons. The Mini Nutritional Assessment (MNA) provides a single, rapid assessment of nutritional status in the elderly of different degrees of independence, allowing the prevalence of protein-energy malnutrition to be determined and to evaluate the efficacy of nutritional intervention and strategies. Easy, quick and economical to perform, it enables staff to check the nutritional status of elderly people when they enter hospitals or institutions and to monitor changes occurring during their stay. Moreover, the MNA is predictive of the cost of care and length of stay in hospital. This publication will be of immense assistance to heads of geriatric teaching units, teachers in nutrition, clinicians general practitioners and dieticians, enabling them to better detect, recognise and start treatment of malnutrition in the elderly.

This book was released on 2021-06-25 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication provides an overview of the common and unique sustainability elements of Indigenous Peoples' food systems, in terms of natural resource management, access to the market, diet diversity, indigenous peoples’ governance systems, and links to traditional knowledge and indigenous languages. While enhancing the learning on Indigenous Peoples food systems, it will raise awareness on the need to enhance the protection of Indigenous Peoples' food systems as a source of livelihood for the 476 million indigenous inhabitants in the world, while contributing to the Zero Hunger Goal. In addition, the UN Decade of Action on Nutrition (2016-2025) and the UN Food Systems Summit call on the enhancement of sustainable food systems and on the importance of diversifying diets with nutritious foods, while broadening the existing food base and preserving biodiversity. This is a feature characteristic of Indigenous Peoples' food systems since hundreds of years, which can provide answers to the current debate on sustainable food systems and resilience.
