The Canadian Diabetes Association guidelines suggests a blood glucose of 10.0 mmol/L (180 mg/dl) or less 2 hours after a meal (this target should be 8.0 mmol/L or less if you are not reaching your A1C target of 7.0 or less). Reaching this target after breakfast may be difficult because often this meal contains food with a high glycemic index. Examples of high glycemic index foods are: white bread, white bagel, Cheerios, Corn Flakes, Rice Krispies. Alternative low glycemic index choices would be 100% stone ground whole wheat bread, heavy mixed grain bread, pumpernickel, All BranTM, Bran Buds with PsylliumTM and Oat BranTM. More information about glycemic index and reference charts are found at http://www.carbs-information.com/glycemic-index.htm.
It is important to make sure that your breakfast is balanced and contains some protein and (good) fat to help slow down the absorption of the carbs and provide proper nutrition. Some suggestions are low fat yogurt, peanut butter, almonds, egg and cheese. For more information consult your dietitian.
Some authorities are suggesting to bolus about 20-25 minutes before eating breakfast as this would give the rapid acting insulin some time to start acting as blood glucose rises from these easily digested carbs.
