1. Avoid boiling with sugar.

Many people add sugar when boiling milk, thinking that this will make the sugar dissolve as quickly as possible. However, they do not know that adding sugar when heating is very unscientific. Because milk contains lysine and white sugar contains fructose, these two substances will form a conjugate at high temperatures - fructosyl lysine. This substance cannot be digested and absorbed by the human body, destroying the nutritional value of the protein. What is worse is that it may also be toxic to the human body. Therefore, do not add sugar when heating milk. If you want to drink milk with added sugar, you can add sugar after the milk cools down a bit.

2. Avoid eating with oranges.

Milk is broken down in the stomach under the action of pepsin and pancreatin, and then enters the small intestine to be absorbed. If milk is eaten together with fruits such as oranges that contain high amounts of fruit acid, the protein in the milk will undergo a complex biochemical reaction with the fruit acid and vitamin C and solidify into lumps. This will affect the digestion and absorption of the protein in the milk and the vitamin C in the oranges. In addition, adverse reactions such as bloating, abdominal pain and diarrhea may occur, so eating both together is not worth the gain.

3. Avoid adding chocolate.

Some people like to add chocolate to milk to get rid of the strange smell in the milk. This is unscientific. Milk is rich in protein and calcium. When eaten together with chocolate, the calcium in the milk combines with the oxalic acid in the chocolate to form insoluble calcium oxalate. Not only is it difficult for humans to absorb, but over time, dry hair, diarrhea, and calcium deficiency may occur. and other phenomena. Therefore, the time for drinking milk and eating chocolate should be separated. It is best to eat carbohydrates such as biscuits and bread when drinking milk.
