Welcome to the Forum shellseekr52. I consolidated some of your posts because they were scattered in several threads. It's better to keep all these together.
Are you on any medication? You wrote in another post that your fasting was usually between 111 and 126 which is too high. Normal readings would be under 100. If you've read some of our most recent posts, you'll realize that most of us here do not follow the ADA guidelines for blood sugar readings because they are too high. Following the ADA diet will also keep your blood sugar too high and that will most likely lead you to medication if you aren't already on them. It's possible to lower your blood sugar, especially in your case if you're not on meds, by changing some of what you're eating and adding some daily exercise. Blood sugar levels that stay at 150 or above for lengths of time may lead to organ damage. This figure varies from person to person. This is why we try to keep a much lower average and much lower fasting and postprandial than the ADA suggests. Since this is at odds with your diabetes class, it's up to you to follow what you feel most comfortable with. However, you need to learn as much as you can about how blood sugar levels affect our body.
If the peaches were canned, they probably had added sugar, so your blood sugar would have risen. Also, you have to consider the glycemic value of food. I believe that blueberries have a lower glycemic value than peaches, meaning they don't have as much fructose to drive your blood sugar up.
Eating a 15 - 30 gr carb snack a couple of hours after a meal will guarantee that your blood sugar will be high. This is ridiculous. A 'normal' person's blood sugar doesn't vary too much except after a particularly heavy carb meal but it will always go back down to normal after an hour or two. If a diabetic or someone "borderline", eats the same thing, his blood sugar will spike way too high and remain there for too long. This will eventually harm the body.
Plain red or white wine may help keep blood sugar lower - but of course doesn't replace meds! Some people may need a snack at night before bed to prevent higher fasting levels in the morning. That snack could be half an apple with cheese or peanut butter, some yogurt or whatever works for you.
If you eat too many carbs at a meal and have 113 afterwards and if the blood sugar stays there and then you eat again, then naturally the blood sugar will rise from that point at the next meal. That would result in even higher levels after the second meal.
Please look through the recent posts here about diet plans, you'll learn a lot. I know there's a lot to digest here 
but you'll get it, honest!
