It is part of the Interception Program and aims to reduce the consumption of ultra-processed foods in order to improve the overall quality of the diet among people at high risk of cancer (WCRF score ≤ 5, corresponding to low adherence to nutritional cancer prevention recommendations: eating a diet rich in whole grains, vegetables, fruit and fibre, and limiting ultra-processed foods, red meat, processed meats, sugary drinks and alcohol). It assesses the impact of a digital intervention (based on the use of the Open Food Facts app) as a complement to the nutritional education provided by the Interception program.
