All About Fructose A Carbohydrate

Jun 21, 2008
Fructose is a low glycaemic index food because fructose does not stimulate insulin, it's all of these calories but it doesn't stimulate insulin. So in fact a soda has a glycaemic index of 53 which is low.

Fructose is contained in fruits and food with fruit ingredients. Minor amounts of fructose are still tolerated. Fructose also raises insulin, blood pressure, and triglycerides stop eating all forms of industrial corn.

Fructose is almost twice as sweet as sucrose, another name for common table sugar. Because of this, you need to use much less fructose than sucrose to get the same amount of sweetness. Fructose is contained mainly in fruits, honey, vegetables and foods with fruit ingredients.

Minor amounts of fructose could still be tolerated but that again depends on individual tolerance. Fructose apparently tricks the brain into thinking you are hungrier than you actually are. Unlike carbohydrates made up of glucose, fructose does not stimulate the pancreas into producing insulin.

Fructose has the same number of calories as sucrose but a lower glycemic index , which means that it causes a smaller increase in blood sugar levels.

A couple of years ago, agave syrup became popular as a "healthier" sweetener because it contains mostly fructose and has a low glycemic index. Fructose can only be metabolized in the liver. Excess fructose can lead to excess triglycerides and lipidemia (the bad cholesterol). Fructose reduced the affinity of insulin for its receptor. This is the first step for glucose to enter a cell and be metabolized.

Fructose is also a monosaccharide and is often referred to as fruit sugar, because it is the primary carbohydrate in most fruits. Its also the primary sugar in honey and half the carbohydrate in sucrose (table sugar). Fructose was labeled with two fluorophores at the C-1 position: 7-nitro-1,2,3-benzadiazole (NBD) and Cy5.5.

The labeling site was chosen on the basis of the presence and substrate specificity of the key proteins involved in the first steps of fructose metabolism. Fructose is particularly appealing to consumers because of its low GI content. The GI measures how quickly certain foods release carbohydrates into the body, which then raise blood glucose levels.

Fructose malabsorption occurs due to the body's lack of fructase, an enzyme normally produced by the small intestine. In IBS patients, there is evidence to suggest that more rapid small intestinal transit could deliver unabsorbed nutrients to the colon and hence lead to an increased gas production, causing pain and diarrhea.

Fructose Malabsorption is not to be confused with Hereditary Fructose Intolerance (HFI), a condition in which the liver enzymes that break up fructose are deficient. In patients with fructose malabsorption, the small intestine fails to absorb fructose properly. Fructose is a simple sugar commonly found in fruits and honey.

Fructose and other sugars contribute to heart disease in yet another way. Dietary sugars increase what doctors call "spontaneous platelet aggregation", an unnatural tendency toward blood clotting.
