A scale for consumer confidence in the safety of food

The aim of this study was to develop and validate a scale to measure general consumer confidence in the safety of food. Results from exploratory and confirmatory analyses indicate that general consumer confidence in the safety of food consists of two distinct dimensions, optimism and pessimism, which can co-exist. Since optimism and pessimism may not be activated by the same events, or at the same time, these dimensions should be assessed and evaluated separately, in order to increase understanding of consumer confidence in the safety of food, and to develop effective food risk communicatio

Factors determining the integration of nutritional genomics into clinical practice by registered dietitians

YesPersonalized nutrition has the potential to improve health, prevent disease and reduce healthcare expenditure. Whilst research hints at positive consumer attitudes towards personalized nutrition that draws upon lifestyle, phenotypic and genotypic data, little is known about the degree to which registered dietitians (RD) are engaged in the delivery of such services. This review sought to determine possible factors associated with the integration of the emerging science of Nutritional Genomics (NGx) into the clinical practice setting by practicing registered dietitians. Scope Search of online databases (Pubmed; National Library of Medicine; Cochrane Library; Ovid Medline) was conducted on material published from January 2000 to December 2014. Studies that sampled practicing dietitians and investigated integration or application of NGx and genetics knowledge into practice were eligible. Articles were assessed according to the American Dietetic Association Quality Criteria Checklist. Key findings Application of nutritional genomics in practice has been limited. Reluctance to integrate NGx into practice is associated with low awareness of NGx, a lack of confidence in the science surrounding NGx and skepticism toward Direct to consumer (DTC) products. Successful application to practice was associated with knowledge about NGx, having confidence in the science, a positive attitude toward NGx, access to DTC products, a supportive working environment, working in the clinical setting rather than the public health domain and being in private rather than public practice. Conclusions There is a need to provide RGs with a supportive working environment that provides ongoing training in NGx and which is integrated with clinical practice

Factors influencing societal response of nanotechnology : an expert stakeholder analysis

Nanotechnology can be described as an emerging technology and, as has been the case with other emerging technologies such as genetic modification, different socio-psychological factors will potentially influence societal responses to its development and application. These factors will play an important role in how nanotechnology is developed and commercialised. This article aims to identify expert opinion on factors influencing societal response to applications of nanotechnology. Structured interviews with experts on nanotechnology from North West Europe were conducted using repertory grid methodology in conjunction with generalized Procrustes analysis to examine the psychological constructs underlying societal uptake of 15 key applications of nanotechnology drawn from different areas (e.g. medicine, agriculture and environment, chemical, food, military, sports, and cosmetics). Based on expert judgement, the main factors influencing societal response to different applications of nanotechnology will be the extent to which applications are perceived to be beneficial, useful, and necessary, and how 'real' and physically close to the end-user these applications are perceived to be by the publi

Perceptions and experiences of early-adopting registered dietitians in integrating nutrigenomics into practice

yesPurpose - This research explores the perceptions and experiences of early adopters of the technology. Design/Method/Approach - Registered Dietitians (RD´s) (N=14) were recruited from the UK, Canada, South-Africa, Australia, Mexico and Israel. Six qualitative interviews and two focus groups were conducted online using a conference calling platform. Data were recorded, transcribed and thematically analysed. Findings - Early adopters of Nutrigenomics (NGx) were experienced, self-efficacious RD’s who actively sought knowledge of NGx through communication with one another and the broader scientific community. They considered NGx an extension of current practice and believed RD’s had the skills to deliver it. Perceived barriers to widening the application of NGx were linked to skepticism among the wider dietetics community. Proliferation of unregulated websites offering tests and diets was considered ‘pseudoscience’ and detrimental to dietetics fully embracing NGx. The lack of a sustainable public health model for the delivery of NGx was also perceived to hinder progress. Results are discussed with reference to ‘diffusion of innovation theory’. Originality/Value - The views of RD’s who practice NGx have not been previously studied. These data highlight requirements for future dietetic training provision and more inclusive service delivery models. Regulation of NGx services and formal recognition by professional bodies is needed to address the research/practice translation gap

Genetically modified animals from life-science, socio-economic and ethical perspectives: examining issues in an EU policy context

The interdisciplinary EC consortium (the PEGASUS project) aimed to examine the issues raised by the development, implementation and commercialisation of genetically modified (GM) animals, and derivative foods and pharmaceutical products. The results integrated existing social (including existing public perception) environmental and economic knowledge regarding GM animals to formulate policy recommendations relevant to new developments and applications. The use of GM in farmed animals (aquatic, terrestrial and pharmaceutical) was mapped and reviewed. A foresight exercise was conducted to identity future developments. Three case studies (aquatic, terrestrial and pharmaceutical) were applied to identify the issues raised, including the potential risks and benefits of GM animals from the perspectives of the production chain (economics and agri-food sector) and the life sciences (human and animal health, environmental impact, animal welfare and sustainable production). Ethical and policy concerns were examined through application of combined ethical matrix method and policy workshops. The case studies were also used to demonstrate the utility of public engagement in the policy process. The results suggest that public perceptions, ethical issues, the competitiveness of EU animal production and risk-benefit assessments that consider human and animal health, environmental impact and sustainable production need to be considered in EU policy development. Few issues were raised with application in the pharmaceutical sector, assuming ethical and economic issues were addressed in policy, but the introduction of agricultural GM animal applications should be considered on a case-by-case basis

Willingness to pay for personalised nutrition across Europe

yesPersonalised nutrition (PN) may promote public health. PN involves dietary advice based on individual characteristics of end users and can for example be based on lifestyle, blood and/or DNA profiling. Currently, PN is not refunded by most health insurance or health care plans. Improved public health is contingent on individual consumers being willing to pay for the service. Methods: A survey with a representative sample from the general population was conducted in eight European countries (N = 8233). Participants reported their will- 25 ingness to pay (WTP) for PN based on lifestyle information, lifestyle and blood information, and lifestyle and DNA information. WTP was elicited by contingent valuation with the price of a standard, non-PN advice used as reference. Results: About 30% of participants reported being willing to pay more for PN than for non-PN advice. They were on average prepared to pay about 150% of the reference price of a standard, non-personalised advice, with some differences related to socio-demographic factors. Conclusion: There is a potential market for PN 30 compared to non-PN advice, particularly among men on higher incomes. These findings raise questions to what extent personalized nutrition can be left to the market or should be incorporated into public health programsEC (FW7) funded Food4me projectThe full text will be available 12 months after publicatio

Nanotechnology applied to European food production – A review of ethical and regulatory issues

Various ethical issues are associated with agrifood nanotechnology, linked to the ethical concepts of autonomy, beneficence, non-malfeasance and justice (ensuring safety, effective risk assessment, transparency, consumer benefits and choice, animal welfare and environmental protection). Nanotechnology applications are currently covered by legislative instruments originally designed for other purposes. Risk assessment procedures are in most cases not specific to (agrifood) nano-materials, resulting in uncertainty regarding the nature and extent of potential risks. There are currently no requirements for nano-materials used in agrifood production to be labelled. Ethical principles, and societal acceptance require labelling of food products that are produced using nanotechnology
