Hi Marshall, The appended comprehensive Canadian study illustrates the research 
that shows the rapid oxidation and very low absorption rates of polyols in 
humans with a negligible, if any, increase in insulin. Setting this fact aside, 
my question was related to the interesting assertion that tasting sweetness 
increases insulin release.  
You also mention “ In humans, xylitol has little to no effect on plasma insulin 
or glucose”?

At least in humans, insulin is released when tasting something sweet. That is 
why things like diet drinks can work against you, the drop in blood sugar makes 
you really hungry, so you end up eating the calories anyway.  However further 
research has indicated that the insulin release in dogs is NOT from the sweet 
taste, and I assumed that was the case in dogs because it can be in humans.  
Also there appears to be kidney damage in dogs as well.

Weird, I tried to copy the appropriate section to the clipboard, but it won't 
copy, tried on two different computers.

http://en.wikipedia.org/wiki/Xylitol#Dogs

Dogs that have ingested foods containing high levels of xylitol (greater than 
100 milligrams of xylitol consumed per kilogram of bodyweight) have presented 
with low blood sugar (hypoglycemia), which can be life-threatening.

The paper:

^ Dunayer, E.K (2004) Hypoglycemia following canine ingestion of 
xylitol-containing gum, Veterinary and Human Toxicology 46(2):87-88

http://www2.aspca.org/site/DocServer/vetm0207f_095-100_.pdf?docID=10462

http://www.gopetsamerica.com/dog-health/hypoglycemia.aspx

Puppies and dogs can develop severe hypoglycemia after consuming sugar-free gum 
sweetened with the sugar-alcohol xylitol. In humans, xylitol has little to no 
effect on plasma insulin or glucose levels, but in dogs xylitol is a strong 
promoter of insulin release and can cause severe hypoglycemia with collapse and 
seizures. With the increased appearance of xylitol-sweetened products in the 
US, xylitol toxicosis in dogs may become more common. Sometimes, a dog will 
outgrow this condition.

  Hi Marshall, I thought the release of insulin happens due to the presence of 
glucose and other similar carbohydrates. I didn’t know that insulin was 
released based on taste. Do you remember where you learned that? I am really 
curious about the news. That would mean that stevia, a sweet but 
non-glucose-releasing compound, triggers insulin?

  The mechanism is interesting. From what I understand when they taste the 
sweetness, the automatic nervous system immediately starts pumping insulin into 
their system to handle the sugar, but no sugar arrives, and their blood sugar 
plummetsm sometimes to the point of death.

    In case this hasn't been brought up.  Please know that xylitol can be 
deadly for dogs.
    They are attracted to the sweetness and seem to be able to sniff it out 
from places it's stored easily.
