DIgitAl diabeTES Treatment - the Healthy Eating, heaLthy Patients Trial

A healthy diet improves glycaemic control and reduces cardiovascular risk in type 2 diabetes (T2D), but access to dietitians is limited. Unlike several countries, Sweden has not implemented interpretive front-of-pack labelling. Smartphone applications may offer an alternative. This trial evaluates the dietary and clinical impact of FoodSwitch, a mobile app providing interpretive labelling to Swedish adults with T2D. Nine hundred individuals with T2D for ≥2 years who regularly shop for groceries will be recruited via general practices and community advertisements and randomized to receive access to FoodSwitch plus standard written dietary advice, or standard written dietary advice only. The primary outcome is change in self-measured glycated haemoglobin (HbA1c) after 6 months. Secondary outcomes include waist circumference, body weight, quality of life, dietary self-efficacy, medication use, hospitalizations, and all-cause mortality. Exploratory outcomes include omics analyses.
