Sugar is added to increase the calories supplied by carbohydrates, but it must be rationed, generally 5 to 8 grams of sugar per 100 milliliters of milk. If you add too much sugar, the growth and development of infants and young children have disadvantages. Too much sugar enters the infant's body and traps water in the body, making the muscles and subcutaneous tissues flabby and weak. Such babies look fat, but the body's resistance is very poor, medically known as the "mud paste type" body shape. Too much sugar stored in the body, but also become a risk factor for some diseases, such as dental caries, myopia, atherosclerosis.

The best is sucrose. Sucrose enters the digestive tract and is broken down by the digestive juices and becomes glucose to be absorbed by the body. Some parents specifically buy glucose for their children, which is not necessary. Glucose is low in sweetness, and it's easy to exceed the prescribed range if you use too much of it, and your child will refuse to eat it because it's not sweet.

There is also the question of when to add sugar. Some parents add sugar and milk heated together, so that the lysine in the milk and sugar at high temperatures (80 ° C to 100 ° C) to produce a reaction, the generation of harmful substances sugar-based lysine. This substance will not only not be absorbed by the body, but also harmful to health, especially to children. Therefore, you should first boil the milk to warm (40 ℃ ~ 50 ℃), and then the sugar into the milk dissolved.
