The reasons are as follows:

1. First, fructose is sweeter than sucrose. In the currently known natural carbohydrates, fructose has the highest sweetness, cooking seasoning to achieve the same sweetness, the amount of fructose than the amount of sucrose less. For modern people with excess energy, the intake of sugar is excessive, because of the high sweetness of fructose, we can enjoy the sweet taste at the same time, can reduce the intake of energy. It is good for health.

2, secondly, relative to sucrose, the same intake of the case, fructose has less impact on human blood sugar. Glycemic index, an index used to measure the effect of a certain dietary composition on blood glucose concentrations. Foods or meals with a high index are digested quickly and absorbed completely when they enter the stomach and intestines, and glucose enters the bloodstream rapidly, resulting in large fluctuations in blood glucose concentrations. Foods with a low index have a long residence time in the gut and are released slowly. Whether for healthy people or diabetic patients, maintaining a stable blood glucose concentration without major fluctuations is the ideal state, and to achieve this state is to make reasonable use of low-index foods. Fructose belongs to the low index food, can be used as diabetic patients can choose sugar, because fructose in the body metabolism does not through insulin. However, diabetics should have some in moderation and not consume large amounts because of its effects.

3, the high sweetness of fructose, as well as the low glycemic index has become the pursuit of a healthy diet of an inevitable choice, but also the World Health Organization, the U.S. Food Safety and Agriculture Organization unanimously endorsed and recommended by the health, safety of edible sugar.
