Brief Summary
To determine the effect on tolerance and gas production from chronic feeding of fermentable fibre (inulin) incorporated into a gel forming fibre (methylcellulose) compared with placebo (maltodextrin)
Detailed Description
Our challenge is to understand how various dietary fibres interact to alter colonic fermentation of FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) with the aim of r...
