Normal Blood Sugars. 1  A normal fasting (no food for eight hours) blood sugar level is between 70 and 99 mg/dL. 2  A normal blood sugar level two hours after eating is less than 140 mg/dL.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). The mean normal blood glucose level in humans is about 5.5 mmol/L (100 mg/dL); however, this level fluctuates throughout the day.lucose levels are usually lowest in the morning, before the first meal of the day (termed the fasting level), and rise after meals for an hour or two by a few millimolar. Blood sugar levels outside the normal range may be an indicator of a medical condition.
