Glucose curve for different amount of carbs

[Rabdos]

Hello

Is there a graph that shows the postprandial glucose curve for the same patient after 10, 30, 50, 80, 100, 150 etc grams of glucose meal?

From what suspect, if you eat 30g of carbs you will spike from 5mM to 7mM and if you eat 60g of carbs, you will not spike at 9mM despite you ate double the carbs.

I would like to see a graph that shows that but if my above suspicion is true, why this happens? How can the body manage/uptake larger amounts of carbs with not proportional effect on blood glucose?

Thanks!

There are graphs showing glucose levels vs. time. They tend to be an average of 100's of people's results because the results of one person can be so variable. For example, 30g of carbs can produce a blood glucose increase in me of anything from 5 to 20 mmol/l .

From my experience, doubling the amount of pure glucose you eat is going to produce very close to double the blood glucose increase. Any other form of carb, I think you're right, will produce less than that.

It's fairly well known that eating some forms of fat with your carbs reduces and delays your blood glucose spike. This is something some diabetics use to match the insulin activity profile better to the glucose release. It's possible that larger amounts of carbs also slow down the glucose release I suppose, but I've not seen this written anywhere.

I recently, on another, forum came across someone who believed there was a trigger point for each person whereby you could eat a certain number of carbs and then suddenly get a big spike from just a little more than your personal threshold. Kind of the opposite of what is suggested here but in the same vein of it not being linear though. They could give no other evidence or source other than their “paid endocrinologist”. I can’t find anything either.

If there are numbers available it would be difficult to correlate in any event as trials always tend to do something not real world to make sure amounts are perfect, e.g. for protein rather than eating a chicken breast they would do whey. So for carbs they would probably do a glucose solution; when you might want to know the results of several slices of cheddar cheese on white bread toast, or varying sized baked potatoes.

Unless it is purely academic interest, I believe you will have to test by yourself, which of course will be more relevant.
