## TL;DR

This study reviews where older adults get their nutrition information and what factors influence their choices, aiming to improve public health strategies.

## Contribution

The study provides a comprehensive overview of nutrition information sources and preferences among older adults through a scoping review.

## Key findings

- Older adults use multiple sources like magazines, family, TV, and healthcare professionals for nutrition information.
- Factors like education level, gender, and trust influence how nutrition information is used.
- Further research is needed to evaluate the impact of these sources on healthy aging.

## Abstract

A nutritionally adequate diet is essential for older adults to support healthy ageing and reduce the risk of malnutrition. With over a million older adults in the UK affected or at risk, understanding where they source nutrition information is critical for designing effective public health interventions. This scoping review mapped existing studies on the sources and preferences for nutrition information among older adults. A comprehensive search of PUBMED, Scopus, and CINAHL (March 2023; updated February 2025) yielded 8936 records, of which 15 studies reporting on 14 research projects met inclusion criteria. The majority of studies reported on multiple sources including magazines, family and friends, television, dietitians, general practitioners, internet and embodied knowledge (hidden and unconscious gained from personal experience). Educational level, gender, and trust were found to influence uptake and use. Further research is needed to assess the impact of these information sources and identify strategies to support older adults in making informed food choices that promote healthy ageing.
