They found pectin had similar benefits.
Soluble fibers and the biome are very interactive, and there can be some very odd interactions there in the digestive system.
Inulin tends to generate a kind of mucus that prevents intestinal leakage, and acts as a home for healthy bacteria.
The pathogen Clostridium difficile (C. diff), aka “Cholera’s little brother” often gives healthy people a debilitating dysentery that can last a month. It affects approximately 500,000 patients annually in the United States, of these around 30,000 will die.
The Japanese learned in the 1960s that C. diff can be blocked with a different, non-pathogenic form of Clostridium (C. butyricum), which can be taken in pill form when a person is at risk of getting C. diff, that is, by being hospitalized.
And I found out that C. butyricum’s favorite food is the soluble fiber “Guar Gum”. Which makes a good therapy great.
Guar Gum also has the added benefit of binding with bile to flush it out of the body. And bile tends to recycle a bunch of things you don’t really want, like several heavy metals.
