Changes in food purchase behaviour on the basis of nutrition facts |
Changes in food purchase behaviour pre-treatment will be compared to post-treatment on the basis of nutrition facts like energy (kcal), carbohydrates, sugars, added sugars, protein, fat, saturated fat, dietary fibre and salt. |

Primary |
Changes in food purchase behaviour on the basis of the Nutri-Score |
Changes in food purchase behaviour pre-treatment will be compared to post-treatment on the basis of the Nutri-Score, representing the nutritional quality of products. The Nutri-Score is based on a discrete continuous scale from -15 (most healthy) to 40 (least healthy). The score is then transcribed into five colour categories (A-E, ranging from bright green (most healthy) to red (least healthy)). |
