Several factors influence how fast a particular carbohydrate raises blood glucose levels, including how refined or processed the carbohydrate is, the chemical and physical structure of the carbohydrate-food fruit sugar, fructose, has a different structure to ordinary sugar, sucrose, for example , how the carbohydrate is cooked, and other substances in the food such as fibre or acid — which help to slow the speed of digestion and in turn lower the GI value How refined the carbohydrate is This is one of the most important factors that determines the GI of foods.

Chemical structure of the carbohydrate The body processes glucose very efficiently, the GI of glucose is ; it cannot metabolise fructose — or fruit sugar — as easily, which is why fructose has a low GI of Physical structure of the carbohydrate The physical structure of the carbohydrate also affects the GI value. Most breads are in the high GI range — not due to the chemical nature of wheat starch, but for two physical reasons: The fine particle size of wheat flour gives digestive enzymes greater surface area to attack and metabolise the bread; The surface area of bread particularly white bread , is also increased by its puffed-out, fluffy structure.
