Informed consent

Declaration of consent for the use of data collected as part of the meala Pizza Challenge 

Dear participant,
Thank you for your interest in our meala pizza challenge. It is important to us to inform you comprehensively about what we do. We will only use your data with your consent and only for the purpose you have specified. Below you will find a description of our pizza challenge and explanations of how we use your data:

I. Background
42 different factors can affect blood glucose – most importantly diet and carbohydrate intake. Pizza poses a particular challenge due to its high fat content. The Pizza Challenge therefore evaluates your own blood glucose management in a playful way and complements it with peer support and exchange with others.

II. Objective of meala
The goal of meala is to better understand the assessment of meals and in particular the effects of nutrients on one’s own body, as well as to contribute to a general increase in well-being. In concrete terms, this is achieved by gaining individual insights through the recording of the above-mentioned factors. Through continuous scientific monitoring, the quality of the statements on a healthy lifestyle is constantly being improved. Studies have shown that the exchange and retrospective analysis of one’s own health values leads to greater health literacy. A better estimation and understanding of the effect of carbohydrates can lead to a more stable blood sugar.

III. Process
meala can be used to better understand one’s own body or as a free tracking tool. meala is basically designed for long-term use, whereby we naturally adhere to the applicable legal data deletion periods. Anyone who lives in the European Economic Area can participate. However, participation may be restricted for health or legal reasons, e.g. due to age or pre-existing conditions that would pose a risk to users. Participants of the meala Pizza Challenge follow the following process or at least parts of it:

1) Completing a general management questionnaire.
2) Wearing a CGM for at least 10 days.
3) Eating their first pizza and estimating their carbohydrate intake
4) Completing a questionnaire about the management of the 1st pizza.
5) Consumption of the second pizza and evaluation of the carbohydrate estimation
6) Filling in a questionnaire about the management of the 2nd pizza.

Depending on the edition of the meala Pizza Challenge, there may be deviations from this process.
As a result, each participant will receive an evaluation of their own carbohydrate estimation.
