We compare experimentally Guideline Daily Amount and Traffic Light nutritional labels.
- •
Participants must compose a daily diet subject to nutritional constraints.

GDA performs better than TL when subjects do not face time constraints.

When time is limited TL and GDA have identical efficacy with 4 nutritional goals.
- •
When time is limited TL outperforms GDA with 7 nutritional goals.
