Brief Summary:
Studies in recent years have demonstrated that the commensal intestinal flora (microbiome) plays a key role in the development of nonalcoholic steatohepatitis (NASH). An unfavourable microbiom can trigger disease development and progression. On the other hand, recent data show that modulation of the microbiom by a diet can prevent the developement of a NASH. Mechanisms of interaction between nutrition, microbiome, intestine and liver are largely unknown. In this research project, the effect of a fibre-rich oat bran on NASH will therefore be investigated. A better understanding of the interaction between diet, microbiome, intestine and liver could form the basis for new preventive therapies of NASH.
Detailed Description:
In recent years, the results of animal experiments and some human intervention studies indicate that the commensal intestinal flora (microbiome) plays a key role in the development of nonalcoholic steatohepatitis (NASH). An unfavourable composition of the microbiome can trigger disease development and progression. On the other hand, recent data show that modulation of the microbiome through diet, such as a high-fibre diet, can prevent the developement of a NASH. It has been shown that the uptake of fibre-rich oats reduces LDL and total cholesterol without altering the HDL cholesterol level. Indeed, the results of several human intervention studies suggest that a regular intake of oat flakes with prebiotic food supplements is sufficient to lower LDL and total cholesterol levels. In a small clinical trial it was also shown that an intake of oat bran with prebiotic food supplements in two servings per day was associated with a significant reduction in ALT and AST activity in the serum of overweight individuals with signs of altered liver function. In addition, the use of oat bran to influence postprandial glucose and insulin response and satiety was discussed.
However, the mechanisms underlying the positive effects of treatments with pro-, pre- or synbiotics are not yet fully understood and generally accepted therapeutic strategies are still lacking. The exact influence of a fibre-rich diet on intestinal microbiom and bile acid composition is not yet known. In the research project described, the effect of oat bran with prebiotic food supplements on NASH will be investigated and mechanisms of interaction between diet, microbiome, bile acids and liver will be uncovered. A better understanding of this interaction could form the basis for new preventive therapies of NASH.
