@evittan I am curious, why do you test your blood glucose and have A1c tests if you are not diabetic? Are you considered to be pre-diabetic, or is because of the family history? I found the articles that @hopeful33250 included links for to be very informative, even for me who has been a controlled diabetic for a number of years now.
I think up to 180 is considered to be OK when you test two hours after a meal. I know that exercise helps so I reserve having breakfasts that have more carbs for days when I exercise early in the day. Occasionally my numbers run high but most of the time they are in decent range. I tested this morning before eating and it was only 77 but my endo wants me to test after various meals also. I do not test daily.
I presume that glass noodles have a lot of carbs in them, and certainly rice does also so that could account for your higher numbers. I eat very few starches, there are other ways I prefer to use up my carb allowance, as in fruit.
Good luck with this. I hope your A1c continues to be in the normal range.
