| What Everyone Ought to Know About Sugar Metabolism |

Most people think of sugar as being what they put into a cup of coffee
in the morning (Sucrose). What they don't realize is any carbohydrate
eaten becomes sugar in the body. Sugar is important because it is the
preferred energy source for most of the tissues and organ systems of
the body. It is also the optimal fuel source for the brain and nervous
system.
The body carefully controls the amount of sugar present in the blood at all times. The entry of sugar into the blood is controlled by the Liver. After a person has consumed a sugar it travels through the gastrointestinal tract enters the portal vein and goes to the liver. Approximately two thirds of all the sugar you consume with each meal will be stored in the liver where it can be released into circulation when blood sugar levels have dropped often as a result of fasting or exercise. The amount of sugar released into circulation by the Liver must be kept in balance with the mount of sugar being removed from the blood by the cells of the body. Once the body becomes saturated with it excess sugar will be converted to fatty acids and stored in fat cells. The body is better able to control blood sugar levels when we consume complex carbohydrates as opposed to simple. A complex carbohydrate must be broken down before it is able to pass through the intestinal wall. The advantage of complex carbohydrates is the longer amount of time it takes to be broken down, digested and absorbed into the blood stream. This allows the body to better control the amount of sugar present in the blood.
Anyone
that wants to attain optimal performance should not cut carbohydrates
out of the diet. What should be controlled is the amount of added
sugars in ones diet. Added sugars are not naturally present in the
foods they are in which is why the are "added" and present us with
several problems.
