I won't elaborate on this. I once heard it in a TV health class. Mainly milk belongs to cold food rather than warm food, and people who are weak and afraid of cold can't drink it. That would be a bit bad.

When a girl reaches her period, her body will become weak. She is generally not allowed to touch cold food, including cold water and ice cream. When it comes to menstruation, stomachache is dysmenorrhea, and menstruation is the performance of palace cold ... milk is cold, which is not suitable for menstrual period and weak people to drink, and some people naturally do not absorb milk, and drinking it will cause diarrhea. ...

Besides milk, girls should eat less cold food. ....................................................................................................................................................................., I'm not sure if I can help you. I'm sorry.
