I did an experiment yesterday. Medium banana. Went up to 9.2. Quite quickly. Took 3 hours to come back down. I used to love them and often had 2 on a working lunch.
Just shows how we are all individuals, doesn’t it. Also, for me, I have noticed how my blood glucose reactions have changed over time. I have had T2 for over 15 years, now. It is almost 9 years since I managed to get control through using Newcastle diet method. Immediately after that I could literally eat any amount of carbs, with no spikes in BG or raised HbA1c. After about 2 years this changed. I found pasta, rice, and and potatoes most problematic, but to a lesser extent fruit. The experiment with bananas has only been recent, but I do wonder if they are ok because I have them with full fat Greek yogurt. So I tried banana on toast, with cinnamon. Again no discernable rise in BG.
I would add that this is my own personal experience, and not advocating it for others to try. I never have been a fan of sugar, or sweet stuff generally, but sometimes a banana hits the spot. Of course there are likely to be other factors at play, such as age, gender, activity levels, stress, exercise etc. So many variables, and I will keep testing to see if my reactions to foods remain static or change. I am just aware that what works for many does not always work for an individual, and we are all individuals. Another example of this is that I often see the advice that to lower a spike in BG a good brisk walk should work, yet for me this results in a rise of 2-3 on the BG meter. Always exeptions to every rule, so only thing for me is to keep experimenting and never assuming that things will remain the same. Next month the banana may be the the thing that pushes my BG out of control. I can live with that.
