fruit and blood sugar spikes

Hi I’m 5 weeks in from being diagnosed type2 . I asked the nurse for a blood sugar monitor as I wanted to see what fruits made me have a spike. I have done my first reading. I had nothing to eat took the reading which was 7.6 had a mini sized apple with a tsp cashew butter. Did another reading...

I am a T2, diagnosed 8 years ago. 73 years old. Have Hypertension, Coronary artery disease, have had 5 coronary artery bypass grafts, and I recently graduated to using Metformin having previously been diet controlled. Can anyone tell me which fruits are least likely to cause blood glucose spikes?
