Public perceptions of biospecimen sampling and uncertainty in the context of personalised nutrition.

ABSTRACT: Personalised nutrition based on analysis of biospecimen generates individual-specific dietary recommendations and potentially, improved health. However, the science underpinning these approaches is evolving and uncertain. Additionally, users must provide a biological sample appropriate to the analytic approach being taken.

Attitudes to personalised nutrition were not affected by sample type, although contemplating p
