Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The main aim of the project is thus testing the effectiveness of a genotype-based personalized dietary intervention targeted at decreasing caffeine intake.
Specific aims of the study include:
* Implementation of the application for mobile devices which will be designed to assess caffeine intake.
* Testing whether providing information on CYP1A2 polymorphism affects effectiveness of the dietary intervention aimed at decreasing caffeine intake.
* Testing whether changes in dietary behavior can persist over time To accomplish the study goals a group of healthy adults will be enrolled. Participants will complete an informed consent procedure. As we aim at decreasing caffeine intake, we plan to first screen for people drinking at least 2 cups of coffee or with total caffeine intake over 200 mg/day. Then genotype screening will be performed and eligible volunteers will be randomly assigned to one of the study groups which receive either dietary advice or dietary advice and genotype information.

group will receive dietary advice and genotype information
Intervention group with genotype information
Results of genotyping will be translated into personalised dietary recommendations. Subjects will be informed about their genotypes from the beginning of the study. The importance of personalised recommendations will be explained.
Control group
group will receive dietary advice
Control group without genotype information
Subjects will receive personalised dietary recommendations, but at the beginning they will not be informed about their genotypes and the meaning of personalisation. Information about their genotype will be given to the participants at the and of study.
