Hi Paul,
How are things working out? Are you finding foods you can eat, and enjoy? If so, share, because this is a real bear to get a grip on. I do know that for sure.
FWIW, the numbers that seem to come up point to the notion that spikes are almost worse for your body, than running a bit high all the time. Seems to be some contention about what is the “magic number” to avoid, but for all the forums and other sources I have found, that number is 7.8 in your terminology. 140 in mine. Kind of like having to deal with the metric system and the imperial system. Drives me nuts when I work on cars, so why should diabetes be any different, right? 
Everyone pretty much gave the same recommendations that I would. I assume you have passed on the cereal and the pasta. Pasta has a fairly low glycemic index number and takes longer to “move through you” so the numbers may not go up as fast, but they will get there. That is why the one and two hour testing is a good thing, but you need to also be aware of what you are eating, relative to that glycemic number, so you can test appropriately.
I have found that some foods I can eat at other times of the day, and do better with them, but as I said elsewhere to you, I did have to give up the cereal and the pasta.
If you just have to have pasta, you may consider this:

Quite a few people I’ve met use it, and do very well with it. The cooking time has to be very precise, or else its no better than regular pasta. I haven’t used it, but the best I can figure is the pasta is ‘coated’ so that it breaks down very slowly over a long enough time, that you don’t get the jolt in your BG. Over cooking it, even a minute, will remove that “coating” and your numbers will rise like normal pasta, or so I am told.
I don’t know your personal situation, but in my case, I live alone, and find it downright impossible to find recipes and suggestions for single servings of most meals. Got lots of “diabetic diet” books, and they would be fun to try, if there was 4, 6, or 8 people to feed, but that’s not how it works for me, so I have to pass on most of what I find, and just fake it, hoping to get a good tip or idea from something. Not sure why I want to make a ten fake pancakes. Oh sure, there are recipes for brownies, but they all serve like, a dozen people, and one brownie is all I could eat. So if I make the full boat, I either have to throw away most of them away, or I will find myself in front of the idiot box, covered in chocolate, and hating myself for downing ten times more carbs than I can cope with. lol!
Hang in there, and if you find stuff that works, please share. Lots of us are in the same, ‘what do I eat?’ situation.
