The aim is to conduct a pilot study to assess the feasibility, acceptability and potential effectiveness of culinary focused nutrition education to promote increased adherence to the Dietary Guidelines for Americans compared to standard low-intensity care.
This is a 15-week, 2-arm randomized controlled pilot trial. In a 1:1 ratio, participants will be randomized to the intervention arm or the control arm. The intervention group will receive a 12-week culinary focused nutrition education program. The control group will receive standard low-intensity care (i.e., printed healthy eating material). Outcome measures will be assessed at baseline and 15 weeks.
