I don't think that 'should' is appropriate in that situation - with diabetes, blood glucose just does what it does, no rhyme or reason is the usual observation.
Would you like to share what the food was? Different foods hit differently, so we may be able to find a likely culprit if we know what the food was.
Biphasic insulin release is such a fascinating subject. From articles I have read, once you have a diminished / absent first phase insulin release, as a pre- diabetic, the probability that you will go on to become diabetic is very high. It’s important for those with pre-diabetes to preserve this initial burst of insulin as it primes the pancreas to release the second phase which continues until homeostasis is achieved . If a person with Pre-diabetes can preserve this initial release by lifestyle changes they maybe able stop the progression to diabetes. This biphasic release of insulin is extremely relevant.
The cream you are consuming with your strawberries is slowing carb metabolism. As fat metabolizes at a slower rate. My understanding is the first phase is released soon after your pancreas detects your blood sugars starting to rise. It is a fast sharp rise, if this initial rise does not bring your blood sugars down, the second phase of insulin is released. My own thoughts, you maybe seeing the second phase which continues until your blood sugars come back down. The fat metabolism has prolonged your second phase release. Happy to be corrected on this.
