Confused Newly Diagnosed

Yes, foods vary a lot on assimilation time and if you eat with fats it takes longer. The 2 hours thing is a good guide but only a guide. Views vary on whether to worry about spikes or just overall carb intake; it's the latter which affects your HBa1C. As bananas have high overall carbs they are best replaced by other fruits. If you are on insulin then assimilation time can affect when it's best to inject

Spikes are included in hba1c as hba1c is an average over the past 3 months, this is why when you record your 2hr readings & get an ESTIMATED hba1c the actual hba1c will be at a higher level, mine was 6 above my estimated, reason is cause your not recording high glucose levels that occur if your only record pre & 2hr post.
This is what I found on it.
