Increased Proportion of Lower Energy Density Items vs. Nutritional Labelling at an Online Supermarket

The proportion of lower energy density vs. higher energy density items will be reversed (67% lower - 33% higher) relative to the default proportion condition (D and DL) (33% lower - 67% higher). Lower energy density items will be defined as lower energy density ≤ median of energy density distribution within a food category.

"When energy density of an item ≤ median of ED distribution within a food category, healthier choice badges will be added to the food item pictures on the online supermarket. Instructions when logging-into the platform will introduce the badges to the participants: In the online supermarket, the green tick allows you to see which products (e.g. muesli) in each product category (e.g. cereals) are healthier choices with fewer calories per gram than most other products in the same category."
