Brief Summary:
This fMRI study evaluated the cognitive mechanisms and the cerebral substrate of decision making when evaluating the healthiness of food products with nutritional information displayed either with a Traffic Light system, a colored nutritional label, and a Guideline Daily Amount system, a numeric label.

Condition or disease Intervention/treatment Phase
Healthy Volunteer Other: Magnetic Resonance Imaging Not Applicable

Detailed Description:

The investigators postulated that Traffic Light label would recruit emotion processes and activation of subjacent cerebral networks.

On the contrary, the nutritional information presented in a Guideline Daily Amount label, would recruit, due to its numeric format and higher complexity, supplementary cognitive processes and activation of related brain regions.
