'Sweeteners raise your blood sugars'

[MeinKraft]

So often I see people presenting this as an absolute fact. Your body tastes something sweet and raises your blood sugar accordingly or something. But I had gestational diabetes and had to test my blood sugar morning, night and pre and post meals so about 7 times a day. I was taking quite a lot of sweeteners at this time and never noticed an effect on my blood sugar. Does anyone know of any studies on this or is it an urban myth? Have any diabetics noticed they can't tolerate sweeteners?

There are different types of sweeteners and they don't all have the same effect.
Short term they don't (i.e. they don't cause a spike like glucose does), but long term they can change your gut biome, and that may affect your insulin resistance. Sucralose seems to be the worst culprit;

No sweetener is good for you. They’re chemicals made in a lab, not food. Better to have small amounts of sugar, than sweetener. Research out this week shows sucralose damages DNA.

This is a study on obese people with BMI of 41+ and does not purport to extrapolate conclusions from beyond its obese 17 participants to the general non obese population

OP was asking about the statement 'Your body tastes something sweet and raises your blood sugar accordingly' and thats probably the study it came from.

Yes they do. It depends on the sweetener. Supposedly some sweeteners trigger the release of insulin. It has to do with the glycemic index. You can get a lot of info on it.

I am T2 diabetic who tests regularly 6 to 8 times a day and uses a freestyle libre occasionally. I've never seen spikes from monkfruit, stevia or erythritol. I do see spikes from glucose and from most fruit.

I know the importance of the gut biome but I find it hard to believe that gut biome affects the pancreas so directly.

This is really interesting. I’ve been doing Keto for two months and the ONLY time I was absolutely ravenously starving on going to bed…. Was the day I took canderel in my coffee and had drink loads of artificially sweetened diluting juice. - I assumed it was psychological. Surely it must be?

I used a CGM for a couple of weeks and my glucose didn't go up at all with diet cokes etc

I'm T2, I don't notice spikes from it (and I test a lot) but I do think/feel it slowly, gently makes my overall levels higher.
