I was reading an exchange on a post regarding sugar and decided to throw my two cents in. This is not from my obesity conference, this is just some basic medical knowledge.
There is a difference between glucose (blood sugar), fructose (fruit and vegetable sugars) and sucrose (table sugar).
Glucose is the bodies preferred energy source and the brain’s only energy source. It circulated in the blood itself and requires an enzyme to initiate its metabolism. Most of the carbs that you eat are processed by your body into glucose, either to be used after being metabolized as energy, or to be stored in the muscle cells or the liver as glycogen for use later. Insulin is secreted primarily in response to elevated blood concentrations of glucose. Insulin fascilitates the entry of glucose into the cells.
Fructose is a naturally occurring form of sugar found in many fruits and vegetables. It is different from glucose because it has a different metabolic pathway and is not the preferred energy source for muscles or the brain. Fructose requires a different set of enzymes for metabolism and is only metabolized in the liver where it is converted to triglycerides . Fructose is more lipogenic or fat producing than glucose. Unlike glucose, fructose does not stimulate the production of leptin which is a key hormone for regulating energy intake and expenditure.
These factors raise concerns about chronically high intake of dietary fructose and because it appears to behave more like a fat in the body than any other carbohydrate. Low glycemic fruits and vegetables are typically higher in fiber and therefore mitigate the carb effect because fiber slows down the metabolism of carbs and helps control the release of the fructose. High fructose corn syrup is in sodas, energy drinks, canned fruits and in things like jellies and pancake syrups. Karo syrup IS HIGH HIGH FRUCTOSE CORN SYRUP.. The take- home message for fruits and vegetables, as it is for most things in the dietary world., Is Portion control and moderation and making the better product choices when you can. Another benefit of physical activity a few hours after eating is to help prevent the storage of fuel that is unused after you have eaten.
The third sugar is SUCROSE otherwise known as TABLE SUGAR. It is primarily obtained from sugar cane and beets.
Fruits and vegetables also contain sucrose. When eaten, sucrose is separated into its individual sugar units, glucose and fructose by enzymes. Both are taken up by their separate transport systems to move along their own metabolic pathways. The body responds to the glucose content of the meal in it’s usua manner. Fructose uptake occurs at the same time. The body uses the glucose as it’s main energy source and the excess energy from the fructose, if not needed will be used in fat synthesis which is stimulated by the insulin release in response to glucose. The goal is to eat fruits and vegetables that are lower on the glycemic index, and contain fiber. Also to not eat so much food at one sitting that your body cannot efficiently use all the fuel you have ingested. Again, the benefic of moderate physical activity a couple hours after you eat. It helps to utilize the excess fuel so that it won’t be stored as fat.
