Scientific limitations in knowledge limit the extent to which diets can be personalised. This paper studies trust and preferences regarding personalised nutrition service providers, regulators, information sources, and information channels, how they influence the intention to adopt personalised nutrition services, and how cultural and social differences may influence intention through differences in trust. Participants were quota sampled to be representative for each of nine EU countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway). A total of 9381 participants answered a questionnaire assessing their intention to adopt personalised nutrition, trust in different service regulators and information sources, and preferences for service providers and information channels.Trust and preferences significantly predicted intention to adopt personalised nutrition. Higher trust in the local department of healthcare was associated with lower intention to adopt personalised nutrition.General practitioners were the most trusted regulators, except for Portugal, where consumer organisations and universities were most trusted. In all countries, family doctors were the most trusted information providers. Trust in the National Health Service both as service regulator and as information source showed high variability across countries.Despite its highest variability across countries, personal meeting was the preferred communication channel except in Spain (where an automated internet service was preferred). General practitioners were the preferred service providers, except in Poland, where dietitians and nutritionists were preferred. The preference for dietitians and nutritionists as service providers highly varied across countries.
