Brief Summary

The aim of this study is to test the efficacy, feasibility, and acceptability of a novel, behaviour-focused personalised nutrition intervention compared to a control personalised nutrition intervention for improving adherence to sustainable and healthy dietary recommendations in university students.

Conditions

Dietary Behaviours; Sustainable Healthy Diet; Personalised Nutrition

Keywords

Sustainable diet; Personalised nutrition; Dietary behaviours; University; Students

Outcome Measures

Primary Outcomes (1)

• Legume intake (grams per day)

  Participants will record their diet at baseline (habitual diet) and endpoint (intervention diet) using an online 24-hour recall method. Legume intake will be calculated using dietary intake records (baseline: 3x 24-hour recalls; endpoint: 3x 24-hour recalls). The primary outcome measure is the change in legume intake (g/ day) as a result of the intervention diet.
