Personalising advice to improve diet quality and cardiometabolic health

The PAD-Q system identified personalised dietary goals, which confirmed poor baseline diet quality, but did not result in greater improvements in diet quality compared to non-personalised advice. However, remote delivery of dietary goals and individualised feedback led to positive changes in diet quality, regardless of personalisation. The PDQS applied to FFQ data effectively captured diet quality changes, supporting its utility in dietary interventions.

PPI activity highlighted strategies to enhance intervention design and the challenge of balancing individual needs with resource constraints. This research advances understanding of personalised dietary advice for improving cardiometabolic health. While the PAD-Q system showed no additional benefit over standard advice in overall diet quality change, the findings underscore the potential for low-cost dietary interventions to improve diet quality.

Future studies should identify subgroups that may derive the greatest benefit from personalised approaches to optimise health outcomes and resource allocation.<br><br>
