Carbohydrates are classified through high-glycemic-index and low-glycemic-index by reference to their intestinal absorption. Carbohydrates with a high-glycemic-index, like glucose itself, honey or starch (potatoes, white bread, white rice, corn flakes) are able to release glucose in blood faster and to increase faster the post-prandial hyperglycemic level than sugars with a low-glycemic index. Fast absorption sugars are taken into account in the case of diabetes but their relationship with overweight is confuse. In non diabetic peoples, they are considered to be useful during physical exercise. But, by the insulin secretion increase, carbohydrates with a high-glycemic-index stimulate lipid synthesis into adipocytes and fat deposit. Considering the importance of overweight prevalence and to focus the attention on the relationship between fast absorption sugars and the fat, we suggest to name them : fatty sugars.
