Do you add sugar first or later when boiling milk? Milk contains lysine, which is an amino acid that can promote the growth and development of children. When milk is boiled with sugar, lysine will react with sugar to produce fructosyl amino acids, which is a harmful substance and affects children's health. Obviously, you can't put sugar in milk first. So what is the correct way to add sugar? That is, after the milk is cooked, pour it into a bowl or cup. When the bowl or cup is not hot, add sugar to dissolve it.

What sugar can be added to milk? In general, the most commonly used is white sugar. But because the main component of white sugar is sucrose, it tastes sweeter. Too much is bad for children's teeth. Therefore, the amount of sugar added to milk should be mastered. There is also glucose, which will be absorbed by the human body quickly after eating, without decomposition and digestion, and is more suitable for newborns and weak children. You can also choose honey, because honey is a mixture of glucose and fructose, but you must choose high quality honey.
