"Sugar substitute" foods are characterized by not adding sugar (such as white sugar, granulated sugar, sucrose, glucose, etc.). ), but instead of sugar (sugar), so the food is sweet, and the packaging of food is usually marked as "sugar-free" (no sugar or artificial sweetness, etc.). ).

Substituting sugar allows you to enjoy delicious food while being "sweet and healthy".

Because the sweetness of sugar substitute is too high, it will be very sweet with a very small amount (for example, it may be 0.0X g). For the convenience of use, maltodextrin will be added as a supplement, so you will still consume some calories when using it.

But even if the food is marked "sugar-free", you will eat a lot and consume too many calories. Therefore, people who want to lose weight by eating sugar substitute foods can't lose weight if they don't limit their calorie intake.

Patients with phenylketonuria (PKU) should not take aspartame.

Biological function of sugar

1, providing energy. Plant starch and animal glycogen are both forms of energy storage. ?

2. Carbon skeleton of substance metabolism provides carbon skeleton for the synthesis of protein, nucleic acid and lipid.

3. The skeleton of the cell. Cellulose, hemicellulose and lignin are the main components of plant cell walls, and peptidoglycan is the main component of prokaryotic cell walls.

4. Intercellular recognition and biomolecular recognition. Oligosaccharide chains of glycoprotein on cell membrane surface participate in cell-to-cell recognition. Some cells contain sugar molecules or oligosaccharide chains on the surface of cell membrane, which form the antenna of cells and participate in cell communication. ABO blood group determinant on the surface of red blood cells contains fucose.
