Association between nutrition self-efficacy, health locus of control and food choice motives in consumers in nine European countries.

We investigated associations between food choice motives and psychological determinants of dietary health behaviour change (nutrition self-efficacy, NS-E, and health locus of control, HLoC) among 9381 participants (18-65 years, 49.4% females) from nine European countries. Price was the highest rated food choice motive.

Breeding by intervening: Exploring the role of associations and deliberation in consumer acceptance of different breeding techniques.

New plant breeding techniques may play an important role in improving food quality, global food security and sustainability. Previous breeding techniques have, however, met with substantial resistance from society. This study examined the role of associations and deliberation in the evaluation of breeding techniques.

Potential Protein Production from Lignocellulosic Materials Using Edible Mushroom Forming Fungi.

There is a need for new protein sources to feed the world in a sustainable way. Converting non-food-grade "woody" side streams into food containing proteins will contribute to this mission. Mushroom forming fungi are unique in their capability to convert lignocellulosic substances into edible biomass containing protein.

Same strategies - different categories: An explorative card-sort study of plant-based proteins comparing omnivores, flexitarians, vegetarians and vegans.

Replacing animal-derived proteins with plant-based proteins has environmental and health benefits. Despite increasing consumer acceptance of plant-based proteins, most individuals do not frequently consume them. Understanding how different consumer groups perceive and categorise plant-based proteins in comparison to animal-derived proteins can support the protein transition, as it might provide insights into both consumer acceptance and how to position plant-based proteins.

Paradoxical consumers in four European countries: Meat-eating justification and willingness to pay for meat from animals treated by alternatives to surgical castration.

To prevent boar taint, male piglets are commonly castrated without pain relief, causing them tremendous pain. There are, however, three alternatives, all of which have pros and cons: (1) surgical castration (SC) with pain relief, which removes boar taint but involves extra work for farmers and veterinarians; (2) raising non-castrated or entire male pigs (EM) in combination with a boar-taint detection method; and (3) immuno-castration (IC) by vaccination, which can lower the risk of boar taint acquired from GnRH pulses, but there are concerns about consumer response. The successful marketing of products from animals treated by alternatives to conventional castration depends on consumer acceptance.

Sex and age differences in attitudes and intention to adopt personalised nutrition in a UK sample.

Aim: There has been an increase in the development of technologies that can deliver personalised dietary advice. Devising healthy, sustainable dietary plans will mean taking into consideration extrinsic factors such as individual social circumstances. The aim of this study was to identify societal groups more or less receptive to and likely to engage with personalised nutrition initiatives.

Short and Long-Term Innovations on Dietary Behavior Assessment and Coaching: Present Efforts and Vision of the Pride and Prejudice Consortium.

Overweight, obesity and cardiometabolic diseases are major global health concerns. Lifestyle factors, including diet, have been acknowledged to play a key role in the solution of these health risks. However, as shown by numerous studies, and in clinical practice, it is extremely challenging to quantify dietary behaviors as well as influencing them via dietary interventions.

All insects are equal, but some insects are more equal than others.

Purpose: Lack of acceptance of insects as food is considered a barrier against societal adoption of the potentially valuable contribution of insects to human foods. An underlying barrier may be that insects are lumped together as one group, while consumers typically try specific insects. The purpose of this paper is to investigate the ways in which Dutch consumers, with and without insect tasting experience, are more or less willing to eat different insects.

Food choice motives, attitude towards and intention to adopt personalised nutrition.

Objective: The present study explored associations between food choice motives, attitudes towards and intention to adopt personalised nutrition, to inform communication strategies based on consumer priorities and concerns.Design/SettingA survey was administered online which included the Food Choice Questionnaire (FCQ) and items assessing attitudes towards and intention to adopt personalised nutrition.

Subjects: Nationally representative samples were recruited in nine EU countries (n 9381).

Application of Behavior Change Techniques in a Personalized Nutrition Electronic Health Intervention Study: Protocol for the Web-Based Food4Me Randomized Controlled Trial.

Background: To determine the efficacy of behavior change techniques applied in dietary and physical activity intervention studies, it is first necessary to record and describe techniques that have been used during such interventions. Published frameworks used in dietary and smoking cessation interventions undergo continuous development, and most are not adapted for Web-based delivery. The Food4Me study (N=1607) provided the opportunity to use existing frameworks to describe standardized Web-based techniques employed in a large-scale, internet-based intervention to change dietary behavior and physical activity.

Providing Personalised Nutrition: Consumers' Trust and Preferences Regarding Sources of Information, Service Providers and Regulators, and Communication Channels.

Background/aims: Personalised nutrition has potential to revolutionise dietary health promotion if accepted by the general public. We studied trust and preferences regarding personalised nutrition services, how they influence intention to adopt these services, and cultural and social differences therein.

Methods: A total of 9,381 participants were quota-sampled to be representative of each of 9 EU countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway) and surveyed by a questionnaire assessing their intention to adopt personalised nutrition, trust in service regulators and information sources, and preferences for service providers and information channels.

The interplay between regulatory focus and temporal distance in the health context.

Objectives: This study identifies how the interaction between temporal distance, regulatory focus, and framing of health outcomes affects individuals' intention to adopt a personalized nutrition service.

Design: A 2 (temporal distance: immediate health outcomes vs. delayed health outcomes) × 2 (regulatory focus: prevention vs.

Meet meat: An explorative study on meat and cultured meat as seen by Chinese, Ethiopians and Dutch.

In this cross-cultural study we investigated how study participants from China, Ethiopia and the Netherlands operationalize the concept of meat and to what extent cultured meat fits or does not fit into this operationalization. We argue that combining the conceptual approaches symbolic boundaries and theory of social practices helps to better understand the possibly culturally dependent operationalization of the concept meat. Ten visiting graduate students from China, 10 from Ethiopia and 10 native Dutch graduate students completed freelist tasks, a pile sort task, interview and essay task, during a single session.

The moderating effect of motivation on health-related decision-making.

Objective: This study identifies how autonomous and controlled motivation moderates the cognitive process that drives the adoption of personalised nutrition services. The cognitive process comprises perceptions of privacy risk, personalisation benefit, and their determinants.

Design: Depending on their level of autonomous and controlled motivation, participants (N = 3453) were assigned to one of four motivational orientations, which resulted in a 2 (low/high autonomous motivation) × 2 (low/high controlled motivation) quasi-experimental design.

Explicit and implicit attitude toward an emerging food technology: The case of cultured meat.

Cultured meat is an unfamiliar emerging food technology that could provide a near endless supply of high quality protein with a relatively small ecological footprint. To understand consumer acceptance of cultured meat, this study investigated the influence of information provision on the explicit and implicit attitude toward cultured meat. Three experiments were conducted using a Solomon four-group design to rule out pretest sensitization effects.

Changes in the influence of affect and cognition over time on consumer attitude formation toward nanotechnology: A longitudinal survey study.

Insights into how consumer attitudes toward nanotechnology are formed and develop are crucial for understanding and anticipating possible barriers in consumer acceptance of nanotechnology applications. In this study, the influence of affect and cognition on overall opinion is investigated longitudinally for emerging nanotechnologies, and compared with conventional technologies. Overall, in attitude formation toward nanotechnology applications, people rely relatively more on affect than cognition.

Willingness to pay for personalised nutrition across Europe.

Background: Personalised 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.

Affect and Cognition in Attitude Formation toward Familiar and Unfamiliar Attitude Objects.

At large attitudes are built on earlier experience with the attitude object. If earlier experiences are not available, as is the case for unfamiliar attitude objects such as new technologies, no stored evaluations exist. Yet, people are still somehow able to construct attitudes on the spot.

Consumer adoption of personalised nutrition services from the perspective of a risk-benefit trade-off.

Through a Privacy Calculus (i.e. risk-benefit trade-off) lens, this study identifies factors that contribute to consumers' adoption of personalised nutrition services.

The perceived impact of the National Health Service on personalised nutrition service delivery among the UK public.

Personalised nutrition (PN) has the potential to reduce disease risk and optimise health and performance. Although previous research has shown good acceptance of the concept of PN in the UK, preferences regarding the delivery of a PN service (e.g.

Promoting healthy dietary behaviour through personalised nutrition: technology push or technology pull?

The notion of educating the public through generic healthy eating messages has pervaded dietary health promotion efforts over the years and continues to do so through various media, despite little evidence for any enduring impact upon eating behaviour. There is growing evidence, however, that tailored interventions such as those that could be delivered online can be effective in bringing about healthy dietary behaviour change. The present paper brings together evidence from qualitative and quantitative studies that have considered the public perspective of genomics, nutrigenomics and personalised nutrition, including those conducted as part of the EU-funded Food4Me project.

Psychological determinants of consumer acceptance of personalised nutrition in 9 European countries.

Objective: To develop a model of the psychological factors which predict people's intention to adopt personalised nutrition. Potential determinants of adoption included perceived risk and benefit, perceived self-efficacy, internal locus of control and health commitment.

Methods: A questionnaire, developed from exploratory study data and the existing theoretical literature, and including validated psychological scales was administered to N=9381 participants from 9 European countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway).

Understanding consumer evaluations of personalised nutrition services in terms of the privacy calculus: a qualitative study.

Background: Personalised nutrition (PN) may provide major health benefits to consumers. A potential barrier to the uptake of PN is consumers' reluctance to disclose sensitive information upon which PN is based. This study adopts the privacy calculus to explore how PN service attributes contribute to consumers' privacy risk and personalisation benefit perceptions.

Socio-psychological determinants of public acceptance of technologies: A review.

Historically, many technologies have been associated with societal controversies, leading to public rejection of their use. It is therefore important to understand the psychological determinants of societal acceptance of emerging technologies. Socio-psychological determinants of public acceptance of 10 (controversial) technologies are reviewed.

Factors influencing European consumer uptake of personalised nutrition. Results of a qualitative analysis.

The aim of this research was to explore consumer perceptions of personalised nutrition and to compare these across three different levels of "medicalization": lifestyle assessment (no blood sampling); phenotypic assessment (blood sampling); genomic assessment (blood and buccal sampling). The protocol was developed from two pilot focus groups conducted in the UK. Two focus groups (one comprising only "older" individuals between 30 and 60 years old, the other of adults 18-65 yrs of age) were run in the UK, Spain, the Netherlands, Poland, Portugal, Ireland, Greece and Germany (N=16).
