Just now at the very start if you were diagnosed from high levels, she may be content with your progress.
9 is within the guidelines, but in my opinion it is too high.
In a normal person, the range will be roughly 4-7, seldomly up to 8.
It is normally recommended a diabetic person aim for no higher than 9 measured 2 hours after a meal. However, almost anyone should aim for no higher than 7.5 - there is lots less risk of complications at this level, and if you reduce certain foods in your diet, your blood sugar is less likely to spike.
Fasting blood sugar should be around 7, or lower if possible. Within reason, lower is better.
Cutting down on pasta, bread, rice etc and replacing the remainder with brown versions can be very helpful as the starch in those products convert to sugar easily. It is normally recommended to eat about 300g of the grain food group in a day. For a diabetic person, it is probably at lot wiser to cut that in half. If that is not enough, cut down further. Replace what you're missing with vegetables, preferably green leafy ones and add a bit more protein (meat, cheese) to your diet to make you feel full. Don't be too scared of fat - your real problem might very well be too much starch. You will find a lot more information in the low carb section - Viv's modified atkins diet is listed on there also and it is a good diet. You may follow it and omit all or most grain products, or you may choose to just cut back on carbs if you haven't already done that.
