The study is part of the international project "The Food Biomarker Alliance (FOODBALL)". The study described here has been assigned to assess biomarkers of the intake of milk and cheese. Up to now, there is an evident lack of data on specific and validated biomarkers of milk and cheese (dairy products), which belong to the most relevant public health related foods in Europe. This study will further provide novel insights into the influence of fermentation of milk-based foods on metabolic effects and postprandial adaptations, which has not yet been studied in depth before using cheese as fermented product. Outcomes will support and expand earlier findings on correlation between the intake of fermented dairy products intake and human health.
