“…'s very motivational" (FG2, Canada) This aligns with previous research which found that personalised information improved healthy eating indices (Celis-Morales et al, 2016) and adherence to a Mediterraneantype dietary pattern (Livingstone et al, 2016). Diffusion theory holds that aspects of the technology such as observability of results, is important for its adoption (Ronteltap et al, 2007). Using nutrigenomic testing with clients was perceived by the RD's to enhance their confidence, render them more engaged as therapists and enable "different" practice.…”

“…Perceived negativity toward NGx was also attributed to skepticism among the wider profession about the efficacy of novel technologies. This perspective fits with diffusion theory which holds that characteristics of the technology pertinent to adoption are likely to be related to its perceived efficacy (Ronteltap et al, 2007). As diffusion theory (Rogers, 2007) would imply, there was a concensus that communication was needed to address misperceptions of the science among the wider profession.…”

“…Perceptions of risk and uncertainty are important for the acceptance or rejection of new food technologies (Ronteltap et al, 2007). The perception of an innovation as low risk has previously been shown to increase pre-adoption of novel technology in allied health professions (Mitchell et al, 2010;Greenhalgh et al, 2004).…”

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. 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. Further research is required to enquire as to the views of the wider dietetics profession. Paper Type Research article. IntroductionNutritional genomics (NGx) is an emerging field focused on interactions between food, nutrition and genes (Ferguson et al., 2016). Increased understanding of gene-nutrient interactions may facilitate health and disease prevention (Casas et al., 2016; Corella et al., 2016;Celis-Morales et al., 2016). A growing market offers genetic tests "direct-toconsumer" as well as via healthcare professionals. The Food4me project has illustrated how personalized nutrition can be delivered online to the public (Celis-Morales et al., 2016). Tests can deliver information linking diet to health, lifestyle, weight or improved fitness (Covolo et al., 2015; Bloss et al., 2011). Omics technologies (metabolomics, lipidomics and transcriptomics) enable highly personalized and targeted approaches to dietary health promotion (Sun and Hu, 2016) which have already been shown effective for outcomes related to cardiovascular disease (Fitó et al., 2016). Consumer interest is high and demand for trained practitioners expected to increase (Berezowska et al., 2015). Registered Dietitians (RD´s) will be key professionals for translating the science of nutrigenomics into practice (Berezowska et al., 2015; Abrahams et al., 2017;Stewart-Knox et al., 2016; Fallaize et al., 2015;Stewart-Knox et al., 2013). TheAcademy of Nutrition and Dietetics (A.N.D), however, do not consider the field ready for routine practice (Camp and Trujillo, 2014), so that application of nutritional genomics has tended to be low amongst the dietetics profession (Collins et al., 2013; W...

Introduction: Personalised nutrition (PN) has great potential for disease prevention, particularly if coupled with the power and accessibility of mobile technology. However, success of PN interventions will depend on the willingness of users to subscribe. This study investigates the factors associated with potential users' perceived value of PN and heterogeneity in these values. Methods: A discrete choice experiment was carried out in a representative sample (N=429 valid responses) from the adult population in Spain. The results were analysed in line with McFadden's Random Utility Theory, using conditional and mixed logit models in addition to a latent class logit model. Results: The conditional and mixed logit models revealed the existence of a significant preference and willingness to pay for personalized nutrition, but the effect on average was not large for the highest level of personalization. The latent class logit revealed four classes of respondent: those who would be likely to pay for a high level of personalized nutrition service, those who would use it if it were heavily subsidized, those who would use only a basic nutrition service, and those who would not be willing to engage. These results could be useful for the design and targeting of effective personalized nutrition services. Conclusions: Over half of adults currently perceive some individual benefit in a high level of PN, which may justify some degree of public subsidy in investment and delivery of such a service. Key points for decision-makers• We found four classes of consumers depending on their attitude through personalised nutrition and their individual characteristics. • Half of adults currently perceive some individual benefit in high levels of personalised nutrition. • Digital service delivery is feasible from consumers' point of view, leading to a reduction in provision costs.
