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

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.

About this study

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

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

-adults aged 18 years and above

Exclusion criteria

  • health conditions impacting fibre intake (e.g., IBD, IBS, colorectal cancer, Crohns disease, ulcerative colitis, diverticulitis)
  • pregnant or breastfeeding
  • food allergies/intolerances
  • following a weight-loss diet
  • no digital device
  • living outside of the UK
  • cognition impairments (such as dementia)

Treatment and study plan

Education

Behavioral

Consumers will receive monthly targeted educational materials on fibre

Control

Behavioral

Consumers will receive educational materials on healthy eating at two timepoints

Primary outcomes

  1. Food intake

    Time frame: One, three and six months (1-hr)

    Food intake will be measured via the eNutri app

Secondary outcomes

  1. 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

  2. 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

  3. Fiberscreen tool

    Time frame: month 3 and 4

    Rate frequency of consumption of ten dietary fibre-rich food categories and estimate portion size
