High blood sugar levels are a symptom of diabetes mellitus. They are also a precursor to this disease, which can be life-limiting. When you ingest sugar or any food high on the Glycemic Index (GI), your blood sugar levels quickly incérse. They peak within 45 minutes of eating. In a normal person, the blood sugar then begins to decrease. Within 2 hours, it’s back to normal levels. When you eat foods that are low on the GI, your blood sugar rises and stays level for an extended time before declining again.
