Brief Summary
Purpose: To better understand the impact of different front-of-package labels (FOPLs) on consumer purchasing intentions and ability to identify unhealthy foods. Participants: \~8,000 Colombians, recruited from Offerwise, that are 18 years or older. Procedures (methods): Participants will be randomly assigned to view images of food and drink products with either a nutrient warning label, Guideline Daily Amount label, Nutriscore label, or no-label control. They will be asked a series of questions about the products and the labels (excluding control group) on them. Questions will also include standard demographic and health related variables.

Study Arms (4)
Control
OTHERThe control arm will show the products with no label.
Experimental: Nutriscore Label
EXPERIMENTALThe Nutriscore label applies a letter grade (A, B, C, D or E) to a product based on certain nutrient criteria.
Experimental: Adapted Peruvian Nutrient Label
EXPERIMENTALThe adapted label is a black octagon with the words in Spanish saying "Excess of sugar,"Excess of saturated fat," or "Excess of salt/sodium" depending on the nutrition contents of the product. Below the octagon is a box with words in Spanish saying "Avoid high consumption"
Experimental: Guideline Daily Amount Label
EXPERIMENTALThe Guideline Daily Amount label highlights the nutrient contents of the product by serving. It lists the calories, total fat, saturated fat, sugar, and sodium, as well are their % of the daily value.
Interventions
Participants will be shown images of juice, bread, yogurt, cookies, and cereal without any added front-of-package labels.
A front-of-package Nutriscore label will be applied to images of juice, bread, yogurt, cookies, and cereal. This label applies a score of A, B, C, D, or E based on the product's nutrition profile.
A front-of-package octagonal nutrient label will be applied to images of juice, bread, yogurt, cookies, and cereal. The label text informs consumers if a product is high in sugar, saturated fat, or salt/sodium. These labels were developed by the Peruvian government and adapted by investigators.
A front-of-package Guideline Daily Amount label will be applied to images of juice, bread, yogurt, cookies, and cereal. The label shows the amount and percent of daily value of calories, total fat, saturated fat, sugar, and sodium in one serving of a product.
