Just to get ahead of this, the abstract from this paper (which is behind a paywall) is observing that erythritol is produced from glucose, and that the subjects who had higher A1c levels had higher amounts of eythritol in their blood. People on other keto FB pages are worrying, but here’s how I see it, based upon what I was able to find:
- The study is looking at endogenous erythritol, not exogenous. There’s nothing here indicating that use of erythritol is inherently bad.
- There’s no assertion that said erythritol is metabolically active, it’s just there.
- Given that it’s secondary to glucose intake, it’s more likely a marker for glucose intake rather than a cause of weight gain itself.
- I’ll defer to the chemists in the gang so far as rate limiting steps, but If I hork down enough candy to fill the trunk of a small German automobile, I’m willing to bet that it would push the production of erythritol and all sorts of other metabolites.
- It will be interesting to see if this can become a useful marker for carbohydrate intake, but Lord knows, it probably wouldn’t be adopted because they’ll just keep seeing that diabetics eating the standard recommendations have elevated levels and it would require too much thought to consider lowing carbohydrate intake.
- I also wonder how exogenous intake would affect these levels.
