What is the glycemic index of foods in the diet for weight loss?

Glycemic index is a concept that nutritionists often used to guide what diet to respect people. But not always able to explain what is meant by this. In short, glycemic index refers to how quickly blood sugar rises after eating products with carbohydrates. This explains prof. Hubert Monikes hospital "Martin Luther" in Berlin.

But why certain foods rising faster blood sugar than others? This is because of the different structure of sugar. There are simple sugars (monosaccharides) and complex sugars (disaccharides, polysaccharides). Complex made up of simple sugars.

Some carbohydrates such as pasta from white flour, sugar, sweets and some rice quickly degraded in the body and covered in blood. So blood sugar rises much faster than if you eat products with complex carbohydrates. These are foods high in fiber such as wholemeal bread, says prof. Monikes. These products are digested fully only when they reach the small intestine. Therefore, the rise in blood sugar is slower. The sugar which is used in households, having an average glycemic index.

Besides the type of carbohydrates but there are other things that determine the glycemic index of a product. It may depend for instance on the way in which is processed a food. There whether it contains other nutrients such as fat and protein (protein).

Glycemic index has values ​​that are determined by how quickly a food raises blood sugar if you eat in '50 it. Fruit (grape) sugar as an index 100. If a person eats carbohydrates with low glycemic index such as fruits and vegetables, blood sugar rises more slowly. Rather white bread, potatoes and sweets (these are just a few examples) increase very quickly blood sugar.

Glycemic index is and how long it lasts rise in blood sugar. This explains why some products that do not rise sharply blood sugar, but the increase lasts longer, have a high index.

What is the meaning of index diet?

The importance of glycemic index diet is great. If food leads to a rapid rise in blood sugar, the pancreas is forced to secrete more insulin. The hormone is needed to "enter" the sugar into the cells, which use it for fuel. With more insulin your blood sugar falls just as quickly as it had risen. You can feel it as hunger. There may be a bout of acute hunger.

If you want to lose weight, the index of food is not the only landmark. According to prof. Monikes key to losing weight is to limit carbohydrates, total calories and increase fluids (mainly water). Glycemic index is important for diabetics who think how much insulin must be injected.
