1. The thicker the milk, the better. Some people think that concentrated milk has higher nutritional value, but in fact, the so-called concentrated milk only reduces the proportion of water. If people with bad stomachs drink strong milk, it will cause diarrhea, constipation, loss of appetite and other bad problems.

2. Milk can't go with chocolate. Some people like to eat milk and chocolate together, thinking it tastes better. In fact, if milk and chocolate are eaten together, it will cause oxalic acid reaction, even lead to calcium deficiency and dry hair.

3. Milk should not be eaten with porridge. Some people think that milk and porridge can complement each other in nutrition. In fact, this practice is not correct. Vitamin A in milk will be destroyed by lipoxygenase in porridge, so it should be eaten separately.

4. Don't drink milk on an empty stomach. Some people like to drink milk on an empty stomach in the morning, thinking that they can supplement nutrition for the body. In fact, it is wrong to do so. If you drink milk on an empty stomach in the morning, the protein in the milk will be forcibly converted into calories and consumed, which actually has no nourishing effect. The best way is to drink milk about two hours after meals, so that the nutrients in milk can be absorbed by the human body to the maximum extent.
