I guess I should have asked what LARGE meant. I know what a spike is, and I can do the maths, what I wanted to know was how much is a large one and what is acceptable given that some foods are likely to increase BG quicker than the insulin can reduce it. So assuming a preprandial of 7 (within the acceptable target range of 5-7), what would an acceptable 2 hour postprandial be? Ignoring T1/T2, your example of 12 would be an unacceptable spike and one of 9 would be OK, in relation to long term damage?
If the above is OK, then would a lower preprandial of 5 followed by the same postprandial of 9 be considered a spike?
Sorry if I'm labouring this point but I've never been able to get a quantitative answer to this.
I think we all differ with how large is large.
Someone following Dr Bernstein's Diabetes Solution eating might call a rise from 4.6 up to 7.1 a massive spike.
While others, on a much higher carb intake might regularly run in the mid teens and spike to the high 20s.
Ideally, the lower the pre meal figure the better (excluding hypos, of course) and the smaller/shorter the rise, the better. Less than 2mmol/l for type 2s is often quoted as a good number to aim for.
