Investigating Food Intake Across the Adult Life Course and Relevant Communication Strategies

June 23, 2025 updated by: Stella Lignou, University of Reading
This project will investigate the effects of different delivery strategies (e.g., personalised dietary advice vs generalised population healthy eating guidance) and individual consumption differences (e.g., eating styles/speeds and food types/preferences) on dietary fibre intake across the adult life-course over a 6-month period.

Study Overview

Detailed Description

  1. does dietary fibre-related knowledge and intake vary across the adult life-course?
  2. what are the common barriers to dietary fibre consumption and how this modulates with increasing age?
  3. what is the role of individual consumption differences on subsequent dietary fibre consumption?
  4. can targeted dietary advice compared with general population healthy eating guidance delivered by the eNutri app promote dietary fibre intake?

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Food intake
Time Frame: One, three and six months (1-hr)
Food intake will be measured via the eNutri app
One, three and six months (1-hr)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Food Consumption Differences
Time Frame: Visit one (1-hr)
A series of validated questionnaires will measure the role of food-related consumption differences (e.g., foodie index, eating behaviour/rate, food preferences, mouth behaviour, food neophobia, knowledge, barriers, etc.) on subsequent food intake
Visit one (1-hr)
Impact of Education
Time Frame: All visits (6-months)
Education will vary depending on group allocation: (1) targeted fibre education will be circulated monthly; and (2) healthy eating advice will be shared twice during the study duration. Consumers will provide feedback on all materials at the end of the study
All visits (6-months)
Fiberscreen tool
Time Frame: month 3 and 4
Rate frequency of consumption of ten dietary fibre-rich food categories and estimate portion size
month 3 and 4

IPD Plan Description

No personal identification data will be shared. The study is not under an obligation to share data, however it is possible that some of the individual (unliked / non identifiable) data will be useful in a meta-analysis and, hence sharing individual participant data (IPD) will be considered.
