Yesterday I had a great day of blood sugars, today I woke with a blood sugar of 147, by lunch time it was 189, all that I ate for breakfast was half a banana. This is very frustrating after such a great day yesterday. I'm new at this diabetes management, and I don't want to get burnt out when I'm just going so good. I took 20 of Humalog with breakfast, and again at lunch. We'll see how it goes. Sigh.

Bananas are usually off my list of foods to eat. Once in a great while I will mix in about 1/8 of a banana into almond flour muffins or waffles. Hubby eats the leftover banana. Maybe try the half banana with some protein, like peanut butter. Bananas seem to give me a long high spike…sigh…miss my banana bread with 3 to 4 bananas, white flour and real sugar…just the thought of it most likely made my BG jump.
Learning what you can and cannot eat to keep BG levels good is a long process.
There are foods that bother some people and not others. Sometimes it isn't easy being unique individuals. While I love a good mystery…diabetes isn't one.

Nick pretty much covered it, so I won't be redundant. To keep it short and sweet, I eat various low glycemic fruits such as strawberries,bluberries, rasberries etc. Bananas are out of the question for me. They spike my blood glucose substantially! They are a relatively high glycemic fruit. For the most part, once you understand what your body is reacting to, the mystery will dissipate.

The ripeness of the banana has A LOT of effect on BG. Go for as green as you can. I've also noticed that banana's spike my BG higher in the morning than in late afternoon/evening.

"The glycemic index (GI) of bananas varies depending upon how ripe the bananas are. This is because a lot of the carbohydrate in green bananas is in the form of a kind of resistant starch which we lack the enzyme to digest. As the fruit ripens, the starch is converted into readily available sugars.
One study of "under-ripe" bananas came up with a glycemic index of 30. One of "slightly under-ripe bananas" that were "yellow with green sections" produced a GI of 42, while another of "over-ripe" bananas was 52. However, most studies of bananas haven't specified the ripeness, and have come up with GIs ranging from 46 to 70. An average of 52 is usually assigned to bananas."

So much going on in your body that one little snapshot test won’t possibly tell the whole story. How much time between breakfast and lunch? Sometimes on banana just won’t cover that time period – especially if you’re active - and you’ll trigger a liver dump (they’re not just for mornings).

Most of us with some control found that by eating small amounts every few hours, the numbers stay low and pretty consistent. Bear in mind too that the blood isn’t always consistently “saturated” depending on your metabolism, and your meter can be up to 20% off. I can get a 10 point +/- reading off the same drop of blood and up to 20 points off if I do 4 tests in one minute from different sites.
Bananas are pretty high in sugars though – I could see the spike two hours after eating it, but ideally you should start to come down after that. More testing would give you a more accurate picture if you can afford it.
