Impact of Dietary Fiber on Gut Microbiome (IMAGE)
Caption
In experiments in germ-free mice that received a transplanted set of human gut microbes, a high-fiber diet was associated with a thick mucus layer in the colon's lining, and resistance to infection by a pathogen. But mice raised with a fiber-free diet had a much thinner, patchy mucus layer, as mucus-eating bacteria in the human microbe mix proliferated. The pathogen was able to get through to the cells of the colon wall.
