Because the most direct harm of high fructose syrup to our human body is to let us eat excess fructose. Excessive fructose will bring unacceptable metabolic burden to human body and liver. In fact, there is no fruit or glucose in fructose syrup. It is just a sweetener obtained from corn starch by enzymatic hydrolysis.

Harm of fructose syrup

This is the most obvious problem. If we usually ingest fructose from fruits, those fructose are wrapped in dietary fiber, so the absorption speed will be very slow. However, high fructose syrup is different. The liquid fructose contained in it will be absorbed at an ultra-fast speed once it enters the human body, and the consequences can be imagined.

After we usually eat glucose, the consumed glucose will be used by various organs or cells of our human body. The unused glucose will be stored in our liver and muscles in the form of glycogen.
