I deliberately didn't give numbers in my last post - because the figures are rather open to interpretation.
And I think we should all make up our own minds.
The bloodsugar101 website, which is looking at much more recent research than, say, the nhs, argues that keeping your bgt under 6.6 at all times will prevent any deterioration of beta cells (this is from memory, you REALLY need to go and read the website yourself).
People on this forum often disagree with that fig. And that is OK. As I said, the figs are open for interpretation, and it is way lower than the NHS suggests. we all get to pick our personal targets, don't we?
But for me, it is less about the size of the spike (although I do always try and spike less than 2mmol/l with each meal), and more about staying under my max level. My lowest bg seems to be about 5mmol. so that means that a spike of 2 would take me to 7ish.
I used to aim for the nhs target. Then I read more, including 101, and now I try for less than 7 at any time, and less than 6.6 at 2 hrs after food.
To be honest, I think trying to elimate rises in bg is a hiding to nothing. it is always going to rise - stress, exertion, food. it is perfectly natural, and impossible to stop. I just take the view that non-diabetics very rarely rise beyond 7mmol/l. even if they do go higher, their pancreas wacks it down very fast. Unless they are developing glucose intolerance, they have a full set of beta cells that function merrily, and permanently. so it seems like a good guideline
to me.
And I don't get stressed when (inevitably) I miss my target. Life is too short to beat yourself up. I just shrug and think 'hmm. smaller portion next time...'
