If you have only recently started self-monitoring your blood glucose levels then 6.9 is about what I would expect and probably better than I would expect if you are still following the standard NHS diet advice but as 4ratbags said you could do better, The key is using your meter to find how your body reacts to certain foods and feeding the data you collect back into what you eat. For me Low Carb Higher Fats (especially good oils) really worked but even folllowing it I don't expect complete control, my own readings have spent the better part of last week drifting much higher than the 4.2 to 5.6 pre-meal numbers I was getting over the previous 3 weeks.
