Currently, the website and study are intended for people who understand English or French. In the coming months, we will translate the site into German in order to open up participation to a larger part of the population living in Switzerland.
Unfortunately not, the project is currently limited to people residing in Switzerland.
Yes, you can participate, but not in the main cohort as the standardized breakfasts could be an issue.
The sensor is water-resistant and can be worn while showering. In the notice, it is said that it can be worn while bathing and swimming as well, however, by experience, it can easily detach during prolonged immersion. You should then avoid swimming during this two weeks. In any case do not take your sensor deeper than 1 meter or immerse it longer than 30 minutes in water.
if you have a BMI (Body Mass Index) below 18.5 or a lean musculature (for example, if you are an elite athlete), those are not exclusion criteria, but we do not recommend you to participate. The filament of the glucose sensor could reach your muscle, which is not dangerous, but on the one hand is painful and on the other hand, distorts the data.
If you can eat what is requested for standardised breakfasts, you can participate.
Reread the email you received with the subject 'Sign up completed'. So you have nothing to do but wait for news from us. We have received a large number of requests and will stagger them to allow the selected participants to be carefully monitored and to maintain continuity from beginning to end of participation in the study in terms of equipment, data processing and laboratory analyses. Applications will be evaluated in batches and you will receive an email when a decision has been made either to include you in the main study or to offer you a so-called 'voluntary' participation in which you will have to pay for the material to participate. The team is doing its best to allow everyone to participate in the main study but given the importance of reflecting the entire population, some groups could be limited and if necessary a 'voluntary' participation will be proposed to allow interested people to participate anyway. In the case where you have enrolled in the voluntary cohort, you simply have to wait, but you will be able to participate in any case.
We cover all material and shipping costs for cohorts B and C. Cohort V participants must pay for their materials. No financial compensation will be given to the participants.
Material costs: 80CHF for microbiome analysis, 65CHF for glucose sensor, and 65CHF for the reader to read glucose values (it can be replaced by a smartphone/iPhone app with phone with NFC, you can try to download the app "FreeStyle LibreLink", if you are able to downlaod the app on your phone, you will not have to buy the reader).
To unsubscribe, you will have to log in one last time on the foodandyou.ch website. Go to Settings (click on your name at the top right), then click on - Interrupt Study - (at the very bottom of the Settings page).
During 14 days, you will be required to: (1) Take a photo of your food and drinks with your smartphone. (2) Track or log your physical activity and sleeping time. (3) Wear a sensor that will continuously measure your glucose level. You will also have to answer online questionnaires and send in a sample of your stool.
Yes, you can sign up at any time. The study will be open all year round. Also, once you have completed the preparation steps and received the material, you will be able to select the date to start the two weeks of tracking.
Normally not, it is important to follow the proposed schedule so that we can compare reactions to standardized meals between participants. If you really cannot eat your standardized breakfast, for example if you are travelling and cannot prepare your glucose drinks, you can postpone it by one or two days, in this case, you should specify this in the notes at the bottom of the tracking weeks form.
Standardised breakfasts are described in a table on the page Participant information.
Yes, you can follow your usual or occasional treatments. Drugs should be recorded in the daily questionnaires (on the foodandyou.ch website and not in the mobile app MyFoodRepo). Note that, it is not necessary to indicate them during the three days of ‘test’.
You can adjust the sending of notifications by SMS or email in the study settings. Log in, then click on your name at the top right, then on the tab - Notifications -.
No, but you may feel a slight numbness in your arm. However, it should not be painful.
You can stop to track your food with MyFoodRepo. Write us via the contact form, if you are before day 9 (or 21 for cohort C participants), we will send you a new sensor so that you can continue the study. If you have already passed day 9 (or 21), we will 'interrupt' the study and give you instructions to complete the study.
Yes, you can board a plane with the sensor and pass through the security doors.
Protect your sensor with a small bandage, or a Tagaderm type patch. You can ask for advice at the pharmacy.
To add to the glucose drink, see the details in the General Instructions.

Make sure you do not confuse your MyFoodRepo app logins with those of the foodandyou.ch website. You can click on -Forgotten Password- to get a new password.
Currently, the application is only available on the Play/Apple Store Switzerland, as it is specifically designed to track the diet of people living in Switzerland. If you want to download the MyFoodRepo app, you have to change the country of your Play store. If you want to participate in the study, you have to download the MyFoodRepo app.
You can continue the study by providing your mailing address so that we can send you the material. We will send you a device that will replace the LibreLink application (FreeStyle Libre Reader).
Our study is fully independent of LibreView and we cannot act on problems related to LibreView. We recommend that you contact their customer service directly.
Citizen science is when members of the general public volunteer in scientific research activities. It increases scientific knowledge, raises people’s awareness of scientific questions and ensures that science reflects and represents the general population. See Citizen Science for more information.
The application MyFoodRepo uses an open source database, the Open Food Repository, and a machine learning algorithm. Combined, these allow you to easily record what you have been eating, either from scanning a barcode or from having the software identify food in your photographs. See MyFoodRepo for more information.
