Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans
Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. This thesis describes how different types of DF and fat levels, can alter BA composition in the caecum/faeces an
