Abstract
Obesity and obesity-related disorders such as cancer, type 2 diabetes, and fatty liver have become a global health problem. It is well known that the primary cause of obesity is positive energy balance. In addition, obesity is the consequence of complex gene and environment interactions that result in excess calorie intake being stored as fat. However, it has been revealed that there are other factors contributing to the worsening of obesity. The presence of nontraditional risk factors, such as environmental endocrine-disrupting chemicals, has recently been associated with obesity and comorbidities caused by obesity. The aim of this review was to examine the evidence and potential mechanisms for acrylamide having endocrine-disrupting properties contributing to obesity and obesity-related comorbidities. Recent studies have suggested that exposure to environmental endocrine-disrupting obesogens may be a risk factor contributing to the current obesity epidemic, and that one of these obesogens is acrylamide, an environmental and industrial compound produced by food processing, particularly the processing of foods such as potato chips, and coffee. In addition to the known harmful effects of acrylamide in humans and experimental animals, such as neurotoxicity, genotoxicity, and carcinogenicity, acrylamide also has an obesogenic effect. It has been shown in the literature to a limited extent that acrylamide may disrupt energy metabolism, lipid metabolism, adipogenesis, adipocyte differentiation, and various signaling pathways, and may exacerbate the disturbances in metabolic and biochemical parameters observed as a result of obesity. Acrylamide exerts its main potential obesogenic effects through body weight increase, worsening of the levels of obesity-related blood biomarkers, and induction of adipocyte differentiation and adipogenesis. Additional mechanisms may be discovered. Further experimental studies and prospective cohorts are needed, both to supplement existing knowledge about acrylamide and its effects, and to clarify its established relationship with obesity and its comorbidities.

Abstract
This study aimed to investigate the distribution of acrylamide (AA) in food by developing a universal method for detecting AA in various foods and analyzing the levels of AA in 437 food samples collected from Southeast China. The developed method was simple, rapid, and widely applicable, with an average recovery rate range of 81.7-94.2% and a relative standard deviation range of 1.7-8.2%. The limit of detection (LOD, 2.0-3.4 µg kg-1) and limit of quantitation (LOQ, 6.0-10 µg kg-1) were also determined. AA was detected in all types of food, with a total detection rate of 76%, and the levels ranged from LOQ to 6020 µg kg-1. Potato chips had the highest level of AA (mean value of 504 µg kg-1), whereas pastries had the lowest level (mean value < 6.0 µg kg-1). Kruskal-Wallis analysis revealed significant differences in AA levels among different foods (H = 229.8, p < 0.05). The AA safety limit intake recommendations suggested that the intake of high-AA foods should be strictly controlled to reduce the risk of potential carcinogenic effects. The developed method provides a useful tool for monitoring AA levels in food.

Abstract
Objective: This study examined the correlations between trust in government and the public's protective behaviors regarding food safety, focusing on the mediating role of risk perception. Methods: The 2013 (1,432 samples) and 2019 (1,276 samples) Taiwan Social Change Survey data were analyzed using ordinary least squares regression models. The bootstrap method was used to examine the mediating effect of risk perception. Results: Perceived integrity of government regarding food safety issues influences all four types of food protective behaviors directly and indirectly via risk perceptions. The four protective behaviors were "not eating that food," "preparing food kit," "preferring organic food," and "overall behaviors." Trust in government directly influences part of the protective food behaviors, while no mediating effects of risk perception were found. Conclusion: The results of this study will deepen our understanding of food consumption behavior, identify key factors that influence public food protective behaviors, and inform food safety management to implement strategies necessary to improve food consumption.

Abstract
Acrylamide (AA) is considered genotoxic, neurotoxic and a 'probable human carcinogen'. It is included in group 2 A of the International Agency for Research on Cancer (IARC). The formation of AA occurs when starch-based foods are subjected to temperatures higher than 120 °C in an atmosphere with very low water content. The aim of this review is to shed light on the toxicological aspects of AA, showing its regulatory evolution, and describing the most interesting mitigation techniques for each food category involved, with a focus on compliance with EU legislation in the various classes of consumer products of industrial origin in Europe.

Abstract
This study investigated the protective effects of minocycline against acrylamide (ACR)-induced neurotoxicity and testicular damage in Sprague-Dawley rats. Forty rats were divided into five groups (eight rats each). Group I received saline (0.5 mL/rat) daily for 10 days and served as the untreated control group. Group II received ACR (30 mg/kg body weight (b.w.)) daily for 10 days. Group III received ACR (30 mg/kg b.w.) daily for 10 days and subsequently minocycline (60 mg/kg b.w.) for five days. Group IV received ACR (30 mg/kg b.w.) daily for 10 days followed by saline for five days and served as the control group for the ACR-minocycline-treated group. Group V received minocycline (60 mg/kg b.w.) for five days. All treatments were administered orally. Rats in group I and V showed normal locomotor behavior and normal histology of the brain and testes. Administration of ACR (Group II and IV) resulted in weight loss and gait abnormalities. Furthermore, neuronal degeneration in the hippocampus and cerebellum and degeneration of the seminiferous tubular epithelium with formation of spermatid giant cells were observed. Ultrastructurally, ACR specifically damaged spermatogonia and spermatocytes. Acrylamide was also seen to cause a significant increase of malondialdehyde levels in the brain and testes. Treatment of ACR-administered rats with minocycline (Group III) significantly alleviated the loss of body weight and improved locomotor function. Minocycline also ameliorated neuronal degeneration and seminiferous tubular damage and decreased malondialdehyde concentrations. In conclusion, minocycline protects against neurotoxic effects of acrylamide and seminiferous tubular damage. Decreasing lipid peroxidation by minocycline might play a role in such protection.

Abstract
The dynamics of organizational risk communication is an understudied topic in risk research. This article investigates how public officials at six government agencies in Sweden understand and relate to risk communication and its uses in the context of agency organizational work on policy and regulation. Qualitative interviews were used to explore the practitioners' views on some key topics in the academic literature on risk communication. A main finding is that there is little consensus on what the goals of risk communication are; if, and how, uncertainty should be communicated; and what role is to be played by transparency in risk communication. However, the practitioners agree that dissemination (top down) to the public of robust scientific and expert knowledge is a crucial element. Dialogue and participation is used mainly with other agencies and elite stakeholders with whom agencies collaborate to implement policy goals. Dialogue with the public on issues of risk is very limited. Some implications of the findings for the practice of risk communication by government agencies are suggested.

Abstract
Uncertainty is an inherent part of knowledge, and yet in an era of contested expertise, many shy away from openly communicating their uncertainty about what they know, fearful of their audience's reaction. But what effect does communication of such epistemic uncertainty have? Empirical research is widely scattered across many disciplines. This interdisciplinary review structures and summarizes current practice and research across domains, combining a statistical and psychological perspective. This informs a framework for uncertainty communication in which we identify three objects of uncertainty-facts, numbers and science-and two levels of uncertainty: direct and indirect. An examination of current practices provides a scale of nine expressions of direct uncertainty. We discuss attempts to codify indirect uncertainty in terms of quality of the underlying evidence. We review the limited literature about the effects of communicating epistemic uncertainty on cognition, affect, trust and decision-making. While there is some evidence that communicating epistemic uncertainty does not necessarily affect audiences negatively, impact can vary between individuals and communication formats. Case studies in economic statistics and climate change illustrate our framework in action. We conclude with advice to guide both communicators and future researchers in this important but so far rather neglected field.

Abstract
Acrylamide in fried and baked foods has the potential to cause toxic effects in animals and humans. A major challenge lies in developing an effective strategy for acrylamide mitigation in foods without altering its basic properties. Food scientists around the world have developed various methods to mitigate the presence of acrylamide in fried food products. Mitigation techniques using additives such as salts, amino acids, cations and organic acids along with blanching of foods have reduced the concentration of acrylamide. The use of secondary metabolites such as polyphenols also reduces acrylamide concentration in fried food products. Other mitigation techniques such as asparaginase pre-treatment and low-temperature air frying with chitosan have been effective in mitigating the concentration of acrylamide. The combined pre-treatment process along with the use of additives is the latest trend in acrylamide mitigation. © 2018 Society of Chemical Industry.

Abstract
In the aftermath of the A/H1N1 pandemic, health authorities were criticized for failures in crisis communication efforts, and the media were accused of amplifying the pandemic. Considering these criticisms, A/H1N1 provides a suitable case for examining risk amplification processes that may occur in the transfer of information from press releases to print news media during a health crisis. We integrated the social amplification of risk framework with theories of news decisions (news values, framing) in an attempt to contribute to existing research both theoretically and empirically. We conducted a quantitative content analysis of press releases disseminated by health and governmental authorities, as well as the quality and tabloid press in 10 European countries between March 2009 and March 2011. Altogether 243 press releases, 1,243 quality press articles, and 834 tabloid press articles were coded. Consistent with research on news values and framing the results suggest that quality and tabloid papers alike amplified A/H1N1 risks by emphasizing conflict and damage, presenting information in a more dramatized way, and using risk-amplifying frames to a greater extent and risk-attenuating frames to a lesser extent than press releases. To some extent, the quality and tabloid press differed in how risk information was presented. While tabloid press articles seemed to follow the leading quality press with regards to content and framing of health crisis coverage, they exhibited a stronger emphasis on drama and emotion in the way they presented information.

Abstract
Acrylamide (AA) is a highly reactive organic compound capable of polymerization to form polyacrylamide, which is commonly used throughout a variety of industries. Given its toxic effect on humans and animals, the last 20 years have seen an increased interest in research devoted to the AA. One of the main sources of AA is food. AA appears in heated food following the reaction between amino acids and reduced sugars. Large concentrations of AA can be found in popular staples such as coffee, bread or potato products. An average daily consumption of AA is between 0.3-2.0 microg/kg b.w. Inhalation of acrylamide is related with occupational exposure. AA delivered with food is metabolized in the liver by cytochrome P450. AA biotransformation and elimination result in formation of toxic glycidamide (GA). Both, AA and GA can be involved in the coupling reaction with the reduced glutathione (GSH) forming glutathione conjugates which are excreted with urine. Biotransformation of AA leads to the disturbance in the redox balance. Numerous research proved that AA and GA have significant influence on physiological functions including signal propagation in peripheral nerves, enzymatic and hormonal regulation, functions of muscles, reproduction etc. In addition AA and GA show neurotoxic, genotoxic and cancerogenic properties. In 1994, International Agency for Research on Cancer (IARC) classified acrylamide as a potentially carcinogenic substance to human.

Abstract
Processing (eg, cooking, grinding, drying) has changed the composition of food throughout the course of human history; however, awareness of process-formed compounds, and the potential need to mitigate exposure to those compounds, is a relatively recent phenomenon. In May 2015, the North American Branch of the International Life Sciences Institute (ILSI North America) Technical Committee on Food and Chemical Safety held a workshop on the risk-based process for mitigation of process-formed compounds. This workshop aimed to gain alignment from academia, government, and industry on a risk-based process for proactively assessing the need for and benefit of mitigation of process-formed compounds, including criteria to objectively assess the impact of mitigation as well as research needed to support this process. Workshop participants provided real-time feedback on a draft framework in the form of a decision tree developed by the ILSI North America Technical Committee on Food and Chemical Safety to a panel of experts, and they discussed the importance of communicating the value of such a process to the larger scientific community and, ultimately, the public. The outcome of the workshop was a decision tree that can be used by the scientific community and could form the basis of a global approach to assessing the risks associated with mitigation of process-formed compounds.

Abstract
Acrylamide (AA) is a compound classified as carcinogenic to humans by the International Agency for Research on Cancer. It was first discovered to be present in certain heated processed food by the Swedish National Food Administration (SNFA) and University of Stockholm in early 2002. The major pathway for AA formation in food is the Maillard reaction between reducing sugar and the amino acid asparagine at high temperature. Since the discovery of AA's presence in food, many analytical methods have been developed for determination of AA contents in different food matrices. Also, several studies have been conducted to develop extraction procedures for AA from difficult food matrices. AA is a small, highly polar molecule, which makes its extraction and analysis challenging. Many articles and reviews have been published dealing with AA in food. The aim of the review is to discuss AA formation in food, the factors affecting AA formation and removal, AA exposure assessment, AA extraction and cleanup from food samples, and analytical methods used in AA determination, such as high-performance liquid chromatography (HPLC) and gas chromatography (GC). Special attention is given to sample extraction and cleanup procedures and analytical techniques used for AA determination.

Abstract
The communication and regulation of risk has changed significantly over the past 30 years in Europe and to a noticeable but lesser extent in the United States. In Europe, this is partly due to a series of regulatory mishaps, ranging from mad cow disease in the United Kingdom to contamination of the blood supply in France. In the United States, general public confidence in the American government has been gradually declining for more than three decades, driven by a mix of cultural and political conflicts like negative political advertising, a corrosive news media, and cuts in regulatory budgets. While the former approach is based on an objective assessment of the risk, the latter is driven more by the perception of the risk, consumer sentiment, political will, and sectoral advocacy. In this article, the author examines three U.S.-based food case studies (acrylamide, bisphenol A, and artificial food colorings) where regulations at the local and state levels are increasingly being based on perceived risk advocacy rather than on the most effective response to the risk, be it to food safety or public health, as defined by regulatory interpretation of existing data. In the final section, the author puts forward a series of recommendations for how U.S.-based regulators can best handle those situations where the perceived risk is markedly different from the fact-based risk, such as strengthening the communication departments of food regulatory agencies, training officials in risk communication, and working more proactively with neutral third-party experts.

Abstract
Currently, many health scholars are concerned about health scares. But what do they mean by the term 'health scare' - are health scares an identifiable phenomenon and how do we currently understand their causation and consequences? By collecting and analysing published articles about events considered to be health scares, this article maps the current views of scholars on their characteristics and causes. Results show that health scares are generally understood as events characterized by fears of catastrophic consequences but little actual mortality. However, the social and economic impacts of these events have often been severe. This survey shows that health scares can be usefully sorted into six categories, each with identifiable internal dynamics, suggesting different communications strategies to achieve resolution in each category. Using the social amplification of risk framework, the conditions under which risk signals were amplified were traced in general terms among major stakeholders. Simple causes for health scare events could not be identified, though some triggers did emerge. Importantly, public ignorance of real risk, media scaremongering and political inaction could be dismissed as primary explanations, though they were sometimes factors in scare events. Implications for risk communication and for future research on risk and public health are discussed.

Abstract
The field of risk communication has its roots in the environmental, chemical, space, and nuclear arenas. As a number of these sectors have now vastly improved their communication strategies, attention is being placed on sectors that have been more problematic as of late. Examples of such sectors, include the food industries and the pharmaceutical/health sector. This article focuses on how large, multinational pharmaceutical companies can better communicate risks by analysis of one specific case, namely, that of the Cox-2 controversy.(1) For purposes of this article, risk communication is best described as "the flow of information and risk evaluations back and forth between academic experts, regulatory practitioners, interest groups and the general public," and "big pharma" refers to the more traditional R & D-based, innovative pharmaceutical companies.

Abstract
One of the concerns often voiced by critics of the precautionary principle is that a widespread regulatory application of the principle will lead to a large number of false positives (i.e., over-regulation of minor risks and regulation of nonexisting risks). The present article proposes a general definition of a regulatory false positive, and seeks to identify case studies that can be considered authentic regulatory false positives. Through a comprehensive review of the science policy literature for proclaimed false positives and interviews with authorities on regulation and the precautionary principle we identified 88 cases. Following a detailed analysis of these cases, we found that few of the cases mentioned in the literature can be considered to be authentic false positives. As a result, we have developed a number of different categories for these cases of "mistaken false positives," including: real risks, "The jury is still out," nonregulated proclaimed risks, "Too narrow a definition of risk," and risk-risk tradeoffs. These categories are defined and examples are presented in order to illustrate their key characteristics. On the basis of our analysis, we were able to identify only four cases that could be defined as regulatory false positives in the light of today's knowledge and recognized uncertainty: the Southern Corn Leaf Blight, the Swine Flu, Saccharin, and Food Irradiation in relation to consumer health. We conclude that concerns about false positives do not represent a reasonable argument against future application of the precautionary principle.

Abstract
Governments and commentators perceive the public to be prone to panic in response to terrorist attacks--conventional or involving chemical, biological or radiological weapons. Evidence from five such incidents suggests that the public is not prone to panic, although people can change their behaviours and attitudes to reduce the risk of themselves being exposed to a terrorist incident. Behavioural responses may be divided into acts of omission, such as not making unnecessary journeys, and acts of commission, such as taking prophylactic medication despite the inherent risk of side effects. Evidence suggests that the public are aware of these differences, and tend to adopt responses proportionate to the risk. Drawing upon the literature in the social and natural sciences, our discussion encompasses differing risk perceptions of terrorist threats and consequences of attacks. How do fear and anxiety interact with behavioural responses to amplify or attenuate perceptions that can be modified through risk communication undertaken by authorities?

Abstract
The unexpected finding that humans are regularly exposed to relatively high doses of acrylamide (AA) through normal consumption of cooked food was a result of systematic research and relevant developments in methodology over decades, as well as a chain of certain coincidences. The present paper describes the scientific approach, investigations and events leading to the discovery of the formation of AA during cooking of foods. In addition, related issues concerning assessment, communication and management of cancer risks and associated ethical questions raised by the finding of the presence of AA in foods will be discussed.

Abstract
Ten years ago, scholars suggested that risk communication was embarking on a new phase that would give increased attention to the social contexts that surround and encroach on public responses to risk information. A decade later, many researchers have answered the call, with several defining studies examining the social and psychological influences on risk communication. This article reviews risk communication research appearing in the published literature since 1996. Among studies, social trust, the social amplification of risk framework, and the affect heuristic figured prominently. Also common were studies examining the influence of risk in the mass media. Among these were content analyses of media coverage of risk, as well as investigations of possible effects resulting from coverage. The use of mental models was a dominant method for developing risk message content. Other studies examined the use of risk comparisons, narratives, and visuals in the production of risk messages. Research also examined how providing information about a risk's severity, social norms, and efficacy influenced communication behaviors and intentions to follow risk reduction measures. Methods for conducting public outreach in health risk communication rounded out the literature.

Abstract
There is a burgeoning interest in the health and illness content of popular media in the domains of advertising, journalism, and entertainment. This article reviews the past 10 years of this research, describing the relationship between the health topics addressed in the research, the shifting focus of concerns about the media, and, ultimately, the variation in problems for health promotion. I suggest that research attending to topics related to bodily health challenges focused on whether popular media accurately or appropriately represented health challenges. The implication was that there is some consensus about more right or wrong, complete or incomplete ways of representing an issue; the problem was that the media are generally wrong. Alternatively, research addressing topics related to sociocultural context issues focused on how certain interests are privileged in the media. The implication was that competing groups are making claims on the system, but the problem was that popular media marginalizes certain interests. In short, popular media is not likely to facilitate understandings helpful to individuals coping with health challenges and is likely to perpetuate social and political power differentials with regard to health-related issues. I conclude by offering some possibilities for future health media content research.
