Hmmm, I read this in Stephen Duren's article on Feeding the Endurance Horse
and thought gut water content might be used to support blood plasma levels
(and ward off dehydration).  Nutrients move across the membrane - is water
not able to move through?

"The additional water and electrolytes in the digestive tract of the high
fiber animals is probably due to the high water holding capacity of plant
fiber. More importantly, the water and electrolyte pool created by a high
fiber diet can be used to combat dehydration and electrolyte imbalances
which derail so many endurance horses."
