What Is Glucose (Sugar In The Blood) And What Purpose Does It Serve?

Question: What is glucose (sugar in the blood) and what purpose does it serve?

Answer: Glucose, or commonly called sugar, is an important energy source that is needed by all the cells and organs of our bodies. Some examples are our muscles and our brain. Glucose or sugar comes from the food we eat. Carbohydrates such as fruit, bread pasta and cereals are common sources of glucose. These foods are broken down into sugar in our stomachs, and then absorbed into the bloodstream.

Normal glucose levels are typically less than 100 milligrams per deciliter, in the morning, when you first wake up, or before eating. We call this the fasting blood glucose or the sugar level. Normal glucose levels 1 to 2 hours after eating are typically less than 140.
