Without knowing what the meal was, and what your numbers were before the meal, and two hours after you had it, we can't say anything sensible. (Even then, we can't diagnose on here!) The thing is, if a non-diabetic has a carby or sugary meal, even they can spike well over the recommended amount... The question is, can your body deal with what you put in it? Was the insulin response good, were you sensitive to your own insulin? With just the number of a spike, with no further context, we know no more than you do.
Do you know what your HbA1c was? The actual number? If it really was good, the odds are, you saw a regular spike which your body dealt with.
Try not to worry. If there is reason for concern, like symptoms that weren't there before, maybe go back to your gp for further digging?
It is perfectly normal for blood glucose numbers to rise - for everyone - after eating any form of carbohydrates. While your body is busy turning carb into glucose, it will also be busy producing insulin to get the glucose out of the blood (the transport system) and into your cells. If your insulin reponse is working correctly, your system should return to balance in about two hours or so.
Within those two hours, the level of glucose can rise a lot. For example (from CGM) a small latte will take me from 5ish to 9.6mmol/l within 45 minutes, due only to the lactose in the milk. Back at 5ish by 90 mins.
So when you do the fingerprick tests around eating you are NOT testing to "see how high you go". You are testing to see how well your system deals with the glucose load you just gave it, whatever it was.
If you take a look at this study, you'll see how various non-diabetic people responded to carbs in food. Without wanting to spoil the surprise, their BGs go up.
This study investigated continuous glucose profiles in nondiabetic subjects. Continuous interstitial glucose measurement was performed under everyday life conditions (2 days) and after ingestion of four meals with standardized carbohydrate content ...
