Public perceptions of personalised nutrition through the lens of Social Cognitive Theory

Rankin, A., Kuznesof, S., Frewer, L.J., Orr, K., Davison, J., de Almeida, M.D.V., Stewart-Knox, Barbara January 2017 (has links)
Yes / Social Cognitive Theory has been used to explain findings derived from focus group discussions (N = 4) held in the United Kingdom with the aim of informing best practice in personalised nutrition. Positive expectancies included weight loss and negative expectancies surrounded on-line security. Monitoring and feedback were crucial to goal setting and progress. Coaching by the service provider, family and friends was deemed important for self-efficacy. Paying for personalised nutrition symbolised commitment to behaviour change. The social context of eating, however, was perceived a problem and should be considered when designing personalised diets. Social Cognitive Theory could provide an effective framework through which to deliver personalised nutrition. / This work was supported by the European Commission under the Food, Agriculture, Fisheries and Biotechnology Theme of the 7th Framework Programme for Research and Technological Development (265494).

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

Stewart-Knox, Barbara, Kuznesof, S., Robinson, J., Rankin, A., Orr, K., Duffy, M., Poinhos, R., de Almeida, M.D.V., Macready, A.L., Gallagher, C., Berezowska, A., Fischer, A.R.H., Navas-Carretero, S., Riemer, M., Traczyk, I., Gjelstad, I.M.F., Mavrogianni, C., Frewer, L.J. January 2013 (has links)
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). The analysis (guided using grounded theory) suggested that personalised nutrition was perceived in terms of benefit to health and fitness and that convenience was an important driver of uptake. Negative attitudes were associated with internet delivery but not with personalised nutrition per se. Barriers to uptake were linked to broader technological issues associated with data protection, trust in regulator and service providers. Services that required a fee were expected to be of better quality and more secure. An efficacious, transparent and trustworthy regulatory framework for personalised nutrition is required to alleviate consumer concern. In addition, developing trust in service providers is important if such services to be successful.
