Effect of Fibre Supplementation on Mixed-meal Challenge Response

Improving healthy physiological processes through nutritional intervention, as opposed to restoring physiology after disease occurrence, is an important new avenue for the reduction of disease burden in the population. A relatively new target for interventions is the gut microbiome. Dietary fibre is a nutritional intervention shown to alter gut microbiome and function. The present study aims to elucidate the relationship between microbiome modulation with dietary fibre and health. In order to assess health improvement, a meal challenge will be given to characterize the physiological processes and their resilience to challenge in healthy volunteers before and after microbiome modulation.
