Default Questions.. Sugar Alcohols + Total Carbs

Apparently, sugar alcohols may have minimal impact on BS readings. I find this to be true. My question when counting Total Carbs, does everyone leave out Dietary Fiber and Sugar Alcohols, or tend to avoid Sugar Alcohols altogether?

I use MyFitnessPal and count all carbs, subtracting nothing. I find it safer than the net carb calculation!

Sugar alcohols are all different. Most are somewhere around 0.2 times the effect of an equal weight of carbs. Some are more, some less. The least of them is erythritol which as I recall is around 0.1 or less.

One of the highest glycerin (not sure if its strictly speaking a sugar alcohol but similar at any rate) is still in dispute but estimates are that it affects BG at a rate of 0.5 times that of carbohydrates. You can find tables in the internet which give the BG impact of the various sugar alcohols.

A bigger problem with them is that they don't digest very well at all. That's why their glucose is largely not liberated and can't get to your blood. But the consequence of this is that they go through undigested to your large intestine where they cause irritation and in large doses, diarrhea. Although they exist in nature (unlike man-made molecules like Splenda and aspertame), they can only be found in extremely tiny quantities here and there. Concentrating them for the purpose of "artificial sweetening" seems like a really bad idea and, I believe, qualifies them as something quite "unnatural".

I vote with Salim on the sugar alcohols but as he and I have discussed a few times, my views on sugar subtitutes of any type verge on paranoia.

I'm also with Steve on dietary fibre. It's carbohydrate until my meter says it isn't (for me).

If you're satisfied, I'm satisfied. BUT, if you have any curiosity at all, why not consider my challenge?

Take a good amount of fiber ALONE and see if you can repeatedly induce a spike with it. That will resolve the question (at least for your metabolism - we can't rule out individual differences) once and for all. IMO, meter readings after mixed meals just can't address this question accurately.

We have enough trouble trying to understand this condition, nutrition, BG, etc. and should be careful not to allow any "urban legends" to develop.

We can always throw a little "science" at it and know for sure, one way or the other.

Salim,

Sorry - challenge refused.

Couple of issues with it. My curiosity doesn't run to fiddling with my diet since the boss would kill me for messing about . Second, my understanding of dietary fibre is that it tends to be represented by things like (sorry UK term follows) "all bran" which I always found totally without taste and of no interest.

I've got a system (called the wife) - it ain't broke - I don't plan to fix it - so for now fibre experiments are not on the menu.

I'm surprised Dr. B hasn't done it. He did it with fat when there were legends out there that some fat could be turned into glucose. He had a large number of people repeatedly test ingesting just fat and answered the question once and for all (negative, of course). Hmm, maybe I should write to him.

Maybe you should, Salim. There so much misunderstanding out there!

Salim, what do you consider a "good amount" serving size? I might just be interested in trying this. Since I rarely eat a lunch I could do it for that meal and not feel deprived of anything. So it would just be the fiber, say flax meal, with lots, and LOTS of water and that is all?

I do subtract fiber from my carb counts as I just don't see it effecting my bs, but this could be the verification I need.

Well, since the belief out there is that fiber is the same as digestible carbs (or in some quarters, "half"), I guess a gram-for-gram comparison would be in order. So, from a common starting point, ingest pure digestible carbs (e.g., potato in order not to confuse things with fructose) in some quantity you can stand, say maybe 20 or 30g.

Next, get a PURE fiber. You could use psyllium husk to represent insoluble and maybe inulin to represent soluble. From a starting point as identical as possible, ingest the same amount of grams of each of those and check BG in all cases.

Then, maybe a third case to be tracked would be measuring BG for the same period from the same starting point but ingesting NOTHING.

The tricky part, I think, is getting that starting point to be really the same.
