Brief summary
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.
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?
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Food intake | One, three and six months (1-hr) | Food intake will be measured via the eNutri app |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Food Consumption Differences | 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 |
| Impact of Education | 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 |
| Fiberscreen tool | month 3 and 4 | Rate frequency of consumption of ten dietary fibre-rich food categories and estimate portion size |
