Introduction and aim of the study:

Food choices are influenced by habits, experiences and socio-economic factors. Discrete choice experiments (DCEs) help identify key factors such as nutritional content and cost that shape food preferences, helping to develop targeted food interventions and inform food policies. Universities, at the forefront of health education and sustainability, however, lack comprehensive data on food preferences in their environment. This study presents a DCE protocol to compare lunchtime meal preferences among university staff and students in six European countries to inform and help improve food policies on campus.

Introduction and aim of the study:

In France, one in three women is overweight or obese. Maternal obesity is associated with an increased risk of pregnancy pathologies, impaired fetal growth, and in the offspring, psychomotor retardation and metabolic diseases in adulthood. These alterations in the programming of fetal development could be due to defects in the supply of omega-3 long-chain polyunsaturated fatty acids (omega-3 LCPUFAs) to the fetus. Indeed, the diet of obese people is often characterized by low omega-3 bioavailability leading to an imbalance in the omega-6/omega-3 FA ratio. α-linolenic acid (ALA), a precursor of docosahexaenoic acid (DHA, omega-3 LCPUFA), plays a crucial role in fetal brain development. The literature shows that ALA supplementation, from the beginning of pregnancy, reduces obstetric complications and improves birth weight. However, according to the ELFE study, more than 75% of women have ALA intakes lower than the 2g/day recommended during pregnancy (ANSES, 2017). One way to remedy this would be to supplement the diet with chia seeds because they contain 64% ALA in their lipid fraction. An adult who consumes moderate amounts of chia improves their ALA status, or even their DHA status.

Breast milk, whose composition is strongly influenced by the environment and the mother's lifestyle habits, including her diet, represents the first food system that an individual is confronted with from birth. The LactOMICS project has implemented an innovative "from fork to farm" approach by integrating the principles of food systems at the exposome level. A multidisciplinary partnership involving 6 units from 4 INRAE ​​departments has thus been created to pool knowledge around the exposome in its nutritional, chemical, and microbiological components, but also statistical and epidemiological analysis and the characterization of food systems and their transitions.
