 A large, long-term data base is a prerequisite for investigation of the determinants of food choices. Thus, the project Z1 aims to expand the family cohort of the first funding phase by 550 families so that multidisciplinary data from 1,000 families, each with at least three members (overall 3,000 participants), in the age range of about 50 to 70 years can be analyzed. All participants answer comprehensive online questionnaires on nutrition, physical activity, living conditions, habits, familial factors and others influencing nutritional behavior. During the second funding period, analysis will be conducted based on the first 1,000 participants. Eighty families with three to four participating members (overall 250 participants) will be invited to an examination centre for additional tests and measurements, including the collection of biological samples (such as blood).

These empirical data form the basis of project 2 (Food Choices), and allow the investigation of epidemiological, sociological and psychological approaches of food selection with focus on intra-individual and inter-individual mechanisms.

In addition, further internet-based applications such as online questionnaires, tests and workflows will be established in subproject Z1, which can also be used for future questions in and after the NutriAct project.
