Interventions/Control_1
Participants will record their lunch intake at the workplace cafeteria using a dietary recording tool for 2 months. In the intervention group, after each entry, participants will receive feedback on a dietary balance score for lunch, the Serving Value (SV) amounts for staple foods, side dishes, and main dishes, and whether the intake of each food group is insufficient, appropriate, or excessive.
Interventions/Control_2
Participants in the control group will record their lunch intake at the workplace cafeteria using a dietary recording tool for 2 months. During the study period, they will not receive feedback on the dietary balance score for lunch, the Serving Value (SV) amounts for staple foods, side dishes, and main dishes, or whether the intake of each food group is insufficient, appropriate, or excessive.
