Neuroeconomic Approach of Food Nutritionnal Assesment

Overview

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.

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.
