Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Continuing the Food & You study already implemented in Switzerland as a pilot study in Germany and replicating the results of Zeevi et al. with a digital cohort and citizen science methodology. a. Determine the interpersonal variability of postprandial blood glucose response and examine the effects of the following influencing factors: diet, anthropometric data, lifestyle, physical activity, sleep, and microbiome composition. b. Comparison of a German cohort with existing Swiss cohorts. c. Assist in the development of a new algorithm to predict PPGR using data readily available (i.e., low user effort and affordable) via such a "digital cohort". | — |
Secondary
| Measure | Time frame |
|---|---|
| Testing the MyFoodRepo mobile application on a German cohort. a. Adaptation of the MyFoodRepo app for German consumers with integration of the BLS database (Bundeslebensmittelschlüssel). b. Determine food consumption and nutritional status of the digital cohort to improve understanding of dietary habits in Germany. c. Evaluate the suitability of the app to track individual food intake at a scalable scale, over longer periods of time, and with sufficient accuracy. | — |
