Does Dr. Fung list xylitol in the "don't" category?

From my brief research, I see that people say xylitol doesn't raise blood glucose or insulin, but I don't recall Dr. Fung mentioning it in the sweetener section in his book The Obesity Code. The reason I'm asking is that I want to find gum that doesn't raise insulin. I found Pur gum, but it is sweetened with xylitol, and I can't find unsweetened gum at all. I recall him mentioning in the book that swishing a sweet solution in your mouth causes a minor spike in insulin, so I am trying to find alternatives. I have found unsweetened mouthwash and toothpaste (Colgate Zero). Thank you!

Answer

For a lot of people xylitol doesn’t affect blood glucose or insulin.

But for some, it apparently does. There isn’t a hard “yes” or “no” and your best bet is probably to just try it and monitor your results.

And the other commentor is correct about pets — it is absolutely deadly for dogs, so keep it in a very secure place and spit it out in a secure trash can that no pets will get into.

Answer

The way that xylitol kills dogs is by raising their insulin levels so that they get hypoglycemia.

Dogs can eat erythritol, though, every day for a long time without toxicity.

Now dogs aren’t people but I stick with erythritol based on that.
