Summary

This study aims to understand how bile acids (BAs) appear in the bloodstream after eating and how this might affect inflammation and metabolism. To do this, we will measure changes in BA levels in 100 healthy women after they eat a high-fat and high-carbohydrate meal. Blood samples (a small amount of 500 µL) will be collected from a finger prick at 7 time points over 5 hours. In the second part of the study, 40 women will be invited back-20 with the highest and 20 with the lowest increases in BAs. These participants will eat the same test meal, and blood samples will be taken from a vein to study markers of health, metabolism, inflammation, and the gut microbiome. By exploring how BAs work in the body, this study hopes to find new ways to understand and prevent chronic diseases.
