Actual (reported)The effect of three front of pack (FOP) labeling schemes (Mexican Guideline Daily Amounts (GDA), Ecuador's Multiple Traffic Light (MTL) and Chilean Warning Labels (WL) in red) on purchasing intentions was evaluated using a randomized experiment of an online shopping simulation. The study employed an online grocery store developed for this purpose to simulate a shopping situation.

Actual (reported)Mean nutritional quality of the shopping cart
The Nutrient Profiling Scoring Criterion model was used as the main measure to evaluate the nutritional quality of the shopping cart.
On the date of randomization
Mean nutritional quality of the shopping cart (negative nutrients)
The Nutrient Profiling Scoring Criterion baseline score, considering only negative nutrients, was used to explore a nutritional quality measure consistent with the key nutrients evaluated.
On the date of randomization
Mean protein content
On the date of randomization, after completion of the online shopping simulation
Mean fiber content
On the date of randomization, after completion of the online shopping simulation
Mean sodium content

Guideline Daily Amounts (GDA) is a purely numerical and reductive labeling system, indicates the grams and percentages (according to the guideline-based daily intakes) per portion of kilocalories, saturated fats, other fats, sugars, and sodium, with no specific judgement, opinion or recommendation.
Multiple traffic light labels, an interpretive nutrient-specific FOP label, use the typical traffic light colors (green, yellow/amber, red) and text descriptors to indicate the high, medium, or low content of total fat, sugar and salt.
All food items displayed the corresponding GDA label in the lower left corner of the front of the package.
All food items displayed the corresponding MTL label in the lower left corner of the front of the package.

Actual (reported)Facts-Up-Front Versus Traffic-Light Food Labels
Warning Labels (WL), another nutrient-specific interpretive FOP labelling scheme, include 'high in' symbols for products that exceed limits of energy, sodium, sugar and saturated fat.
Food products were labeled with "High in" labels In the lower left corner of the front of the package. In total, 37 of the 60 food products in the shopping site did not display a WL.
Participants viewed a short (less than 1 min) video explaining how to interpret the label.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
