NCT05067465

Brief Summary

The Biomarker study will be conducted (i) to establish biomarker profiles that reflect the daily diet and regularly dietary habits, (ii) to complement self-reported dietary habits and (iii) to reduce gaps between self-reported information and real dietary intake. The study aims to assess relationships between defined nutrient intake (four groups: 1. Milk and dairy products, 2. Whole-grain products (rich in soluble fibers), 3. Sausage and processed meat (pork), 4. Meat-free sausage and meat alternatives (based on egg, soy) and resulting biochemical markers in human samples (plasma, serum, 24 h urine). In a next step, we will focus on unraveling the connection of the established diet-related metabolites with biomarkers of health and disease status, with focus on cardiovascular diseases (CVD).
