All sugars (sucrose, fructose, lactose) turn into glucose fastest of all. (Starchy carbohydrates like potatoes and bread are second fastest to turn to glucose.)
Glucose is the primary energy source for our bodies in our modern life. As soon as our body senses glucose it releases insulin, which binds to the glucose and unlocks our cell’s kitchen door to deliver glucose to our muscle, brain and many other cells.
However, fructose is interlocked in the fibrous material that also comprises most fruits. Fibre slows the release of fructose into our bodies, slowing its transition to glucose, thus slowing insulin production. Without fibre, we get insulin spikes that are not good for us in a variety of ways. And whenever there is insulin coursing through our bloodstream, we WILL NOT burn fat. The presence of insulin prevents our bodies from turning to a secondary source of energy: stored fat.
Eating whole fresh fruits that have high fibre content and many essential vitamins and minerals is the best way to get your sugar. You can eat too much fruit though and get fat. Fruit juices stripped of fibre is like drinking kitkats. Whole fruits – 2 a day, morning and noon, is the optimal way to go.
