<< Last semester I took an anatomy class in which the main function of the colon was describes as absorbing water. It absorbs more water than the small intestine, its the last stage in making feces. They also say the colon absorbs the break down products of bacteria. The bacteria are mainly in the colon not the small intestine so if we get anything from the bacteria it would be from absorption by the colon. Frank. >> loved anatomy, was teaching it at a junior college a few years ago. The data on the colon is rather incomplete. It absorbs a lot of things, not sugar, but many things, like Calcium, and apparently B12, which is made there, in a healthful colon. Have some good references on all this will post them eventually.
