‘Tolerating’ carbs and one more question

[Midgie]

@Leadinglights mentioned on another thread (I didn’t want to hi-Jack that one) about tolerating carbs. How much would your BG need to rise pre and post to evidence intolerance? (2hrs?).

I’ve seen sweets with no sugar and instead they have polyols. If they are classed as carbs does this mean I can’t have them? Thanks

If you are talking about real food then it is suggested that an increase of no more than 2-3mmol/l after 2 hours indicates the food is tolerated with an aim of the 2 hour post meal to be no more than 8-8.5mmol/l
Products containing polyols like sweets although 'sugar' free are not carbohydrate free and people's tolerance varies but they can often give people stomach issues if eaten in quantity.
Somebody mentioned that cough medicine containing sorbitol had had an effect on their blood glucose.

Thanks, ‘stomach issues’ would be most welcome at the moment! ;-)

75g of glucose and then two hours sitting around doing nothing.
Two hours later, the BG should less than 11.

That surely is the official glucose tolerance test. I'm not sure if that is what the OP meant.

That’s the best way to do it, though, as it’s pure carbs and gives a good idea about tolerance. Carbs mixed with fats and/or protein might not give an indication.

If you're testing pre and post meals, it's the effect of the overall meal on your blood glucose that matters in terms of maintaining "good control" though. I can eat more carbs at a meal without seeing too high a rise in BG when I've had fat and protein too. So I factor that in when thinking about my personal carbohydrate tolerance.

There's no mention of meals or good control.
The OP was asking about 'tolerance' to carbs.
If you want to find that out, use a test that's pretty much pure carbs and designed to determine how well you are responding to them.

Thanks for the answers, all helpful.

Yes, that is the only answer.
The same as any non diabetic.

The comment in another thread that I thought triggered the question was talking about how much carbohydrate someone is able to tolerate in their diet

Yes it was

I found that once I was seeing under 8mmol/l at the 2 hour point I had reached a tipping point and week on week the number reduced even though I was eating the same meals. It sank gently, down to under 7mmol/l and I lost a lot of weight.
I assumed that showed that I had reduced my carb intake to such an extent that my metabolism was recovering. I was eating a maximum of 50 gm of carbs each day then.
My Hba1c reduced down to 42 from 91, so I thought I was doing something right, however, it went no lower, so I decided to reduce down another 10 gm of carbs a day. At the end of a year, and 3650 carbs fewer, my Hba1c was exactly the same, so it is not an exact science.
