Fructose is a type of simple sugar that makes up 50% of table sugar.
And it comes from natrual foods, such as fruits or honey.  In these forms, it can be part of a balanced and nutritious diet.
Fructose has the effect of directly supplying heat energy, supplementing body fluids and nourishing the whole body, which is easier to absorb and utilize than glucose, and is better for supplying energy and supplementing body fluids than glucose.
Unlike glucose, fructose causes a low rise in blood sugar levels.    Therefore, some health professionals recommend fructose as a “safe” sweetener for people with type 2 diabetes, which can be applied to a variety of food.
