How does E. Coli help digest matter in the large intestine?

Answer 1

We are not cows. E. coli does not help us digest anything. There are certain carbohydrates we cannot digest, like cellulose and some sugars from beans and cabbage. E. coli help themselves.

E. coli is part of the normal flora in the large intestine. Their presence can protect us from yeast infection.

Answer 2

E. Coli and other bacteria in your large intestine can digest insoluble fibers or resistant starches that your small intestine can't. [The small intestine digests 95% of whatever you consume--anything not digested goes straight through to your large intestine.] This breakdown by bacteria is a chemical process called fermentation--where the bacteria consumes the carbohydrate, turning it into gas, acids, and alcohols [ which your body can then absorb]. and the excess gas can lead to flatulence, or "farting." how nice.
