When I first found I was diabetic, I used a lot of test strips. I profiled all the foods I liked a lot. (tested before eating the food, tested again just after eating it, and tested again 2 hours later to see if the number came down or remained up). I used to love orange segments and my wife would keep a bowl in the frig. for me. I found 3 orange segments would raise my number by 200 and stay there for most of the day. I haven't eaten an orange since.You got that right, a A1C at 8.4 is not good and will give you complications which will kill. Someone stated earlier that "all fruits are good" which is not the case. For example, banana's are caloric intense and I can't only consume 1/3 at a time or my BG will go through the roof. Things are like apples are the apposite and do nothing to raise my blood glucagon. When i got a CGM*, it changed my eating habits, reduced my A1C and improved my life very much.. But if you like to eat like I do, then exercise is your freind. That is the more you move around, then the more you can eat care free.
* What is continuous glucose monitoring? Continuous glucose monitoring automatically tracks blood glucose levels, also called blood sugar, throughout the day and night. You can see your glucose level anytime at a glance. You can also review how your glucose changes over a few hours or days to see trends.
You are right about certain foods, and the need to modify their use.
And all fruits are good, but not all fruits are good for a diabetic. It depends on the effect a fruit has on the each person's blood sugar.
On days I don't have time to eat before leaving the house, I cut up and apple in thin slices. It doesn't raise my numbers and keeps me from (at times) feeling sick.
I am glad you mentioned the use of apples. Glad you can use them. They have been a great "safety net" for me.
