High Glycemic Index (GI) foods contain carbohydrates that are rapidly digested thus raise both bloog sugar and insulin, while Low Glycemic Index foods slowly release glucose and insulin into the blood stream. Examples of high GI foods are, white bread, refined breakfast cereals, and concentrated sugars, examples of low GI foods include whole grains, oat, most fruits, vegetables, nuts and legumes.
Recent research revealed the benefits of decreasing carbohydrates intake, since high carb (specially theose with high GI) have many negative impacts on our health, and the preference of low GI foods over the the high GI foods is well established. Many people are now restricting their high GI carbs intake to a great extent.
There are no attempts to convert high glycemic foods into low glycemic foods, yet there are some products that are promoted for weight loss for the same property of minimizing glucose release, these are the carb blockers.
Carb blockers extracted from white kidney beans, they neutralize the digestive enzyme alpha amylase, and thus prevent this enzyme from converting starch into glucose, and reduce the amount of carbs absorbed. This mechanism makes them not interfering with absorption of simple sugars including the essential sugars. Simple sugars are present in far less amounts than starch in many foods.
Carb blockers, through minimizing conversion of starch into glucose can convert high glycemic index foods into low ones. You can read the details of carb blockers here..Dietrine
