@mirdragon I was diagnosed Type 2 several years ago.
I absolutely agree that the advice given is confusing. The thing I would say to you is testing is important
My GP practice is common in concentrating on a three-monthly HbA1c blood test. My last result was quite high.
To the medics this tells them how well or badly your disease is progressing - and is absolutely necessary.
I will be blunt and say it does not help me day to day - it just tells me I have been a 'bad boy' for the last three months.
In the beginning, I used testing strips and a meter, but got out of the habit.
What changed things for me was a Freestyle Libre 2 meter. Please do NOT get one of these just cos I say so - my point being that I started testing again. I was surprised to find that half a ripe banana caused a spike in my glucose. Also with granola.
I guess my advice is - even though your GP practice probably won't prescribe them, get testing strips. Use them to suss out which foods cause spikes for you.
ps. I am not telling you to stop eating bananas. You need to suss out what is right for you.
