[RC] Humans and fiber - k s swigart

Bruce Weary said:

Marathon runners consume carbs for energy with a
little protein to prevent catabolism, not fiber or fat.

Since humans don't have much by way of ability to deconstruct the
structural carbohydrates that are synonymous with fiber while horses do,
saying that human athletes don't eat fiber for an energy source is
hardly relevent.  The human digestive system doesn't really have the
ability to break the structural bonds of structural carbohydrates.  The
horse's does.

Your horse will get a lot more energy from eating beet pulp than you
will.  Although it won't be quick energy.

There is no way for a horse to eat enough during the course of an
endurance ride to provide it with enough energy to fuel the effort of
the entire ride, even if you were to feed it straight glucose.
Endurance horses fuel their efforts with what they ate the day or so
before.  What they eat during the course of the ride does not provide
them with the energy they need for the ride.  What they eat duirng the
course of the ride provides them with the ability to keep the GI tract
functioning and keep the metabolic pathways open.

Some fiber keeps the GI tract functioning, and some form of sugar (of
which starch is one but so is molasses) to keep the metabolic pathways
open.  Oh yeah, and water.

How much molasses and/or other starches and sugars there is in beet pulp
varies dramatically.  Some batches of beet pulp are loaded with sugars
(it is, after all SUGAR beet pulp, so it depends on how much of the
sugar was taken out during the processing).
