It appears to me, that we have been talking about two different things
here. * The Lyle McDonald thread you referenced above talks about how
many CALORIES may be absorbed from the fermentation products of
soluble fiber, which are short chain fatty acids. * * So does the
second reference. * The third says there are no calories, but then
went on to say the exact fermentation products depend on the bacteria
present.

In any case, I thought the whole time we were talking about deducting
fiber from the CARB count. * These are two very different things.
All the medical/scientific references I found in a quick search say
the soluble fiber is broken down into short chain fatty acids. * And
they also say that some of these short chain fatty acids are believed
to actually help regulate blood glucose levels, as well as offer other
health benefits.

Thanks for the educational links and references. I certainly
thought before that since fiberr is a carb and since human
digestive enzymes digest starch to glucose, then enzymes
from intestinal bacteria would digest fiber into glucose.
Seeing calorie estimates I considered counting those
calories as carb calories versus deducting fiber in spite of
those calories. Until this discussion I did not consider that
the calories absorbed might be from other nutrients made by
the bacteria in the digestion/fermentation process. Based
on this lesson I am adjusting my view of fiber.

Now I'm confused. Why would they deduct the fiber only if it's above
5g?

I was in error and in pointing that out, you also proved my point.

Hmmm. Why do you think diabetics are told to bolus for a mere 5 grams
of carbs if they didn't have significant caloric or glucose impact?

No, you were not in error on that point. Diabetics are in fact told
to deduct fiber if it's above 5g. Here it is from the American
Diabetes Association website:


http://www.diabetes.org/nutrition-an...loser-look.jsp

"Total Carbohydrate

The grams of sugar and fiber are counted as part of the grams of total
carbohydrate. If a food has 5 grams or more fiber in a serving,
subtract the fiber grams from the total grams of carbohydrate for a
more accurate estimate of the carbohydrate content.

Fiber is part of plant foods that is not digested. Dried beans such as
kidney or pinto beans, fruits, vegetables and grains are all good
sources of fiber. The recommendation is to eat 25-30 grams of fiber
per day. People with diabetes need the same amount of fiber as
everyone else."

Perhaps you missed my previous post where I covered that. It doesn't
prove your point as you think it does. It in fact refutes it and
agree with everything I've been saying and to all the references and
research info aI provided. Basicly you have it completely
BACKWARDS. The reason they are telling diabetics to DEDUCT fiber if
it's over 5g is because fiber isn't digested like carbs and if you
don't deduct them, you;re carb count will be too high.

"Carbohydrate Counting: A Practical Meal-Planning Option for People
With Diabetes

Similarly, dietary fiber is
not usually digested. So patients need to
be taught that if a food contains ™ 5 g of
fiber per serving, the total amount of
fiber must be subtracted from the total
amount of carbohydrate before calculating
an insulin dose."


What they are saying is that if the fiber carbs are less than 5g,
there is no need
to deduct them, because the amount is too small to matter. However,
if the amount is greater than 5g, then they should be deducted
because
they aren't digested as carbs, don't act like carbs, and if you don't
adjust for that by SUBTRACTING those fiber carbs, your dosage will be
based on an incorrect carb number that is too high and consequently
the dosage will be too high.
