Precautions for drinking milk:

1, can't drink milk on an empty stomach, it's best to eat with some starchy foods: when you are on an empty stomach, the gastrointestinal peristalsis is fast, which greatly shortens the retention time of milk in the stomach and is not conducive to the digestion and absorption of nutrients. If you eat some starchy foods such as steamed bread and bread while drinking milk, it can help the human body fully absorb the rich nutrition of milk. Of course, choosing milk after meals will have the same effect.

Don't drink milk directly, but chew or taste it with a spoon. Dragging milk will directly contact with gastric acid and form acidic protein clots, which may cause diarrhea and bloating for people with weak stomach and intestines. Chewing slowly helps to neutralize saliva and milk and help the human body digest and absorb nutrients.

Don't eat fruit or drink juice within one hour after drinking milk. The ingredients of fruit juice often make some protein in milk coagulate in the stomach, making it difficult for the human body to absorb.
