When you drink Mengniu pure milk, you will have diarrhea, but not when you drink anything else. Maybe you are intolerant of this brand of milk, and your gastrointestinal system can't stand this kind of stimulation, so you can't digest and absorb it normally, so you will have diarrhea.

So since drinking Mengniu pure milk has loose bowels, don't continue to drink it. You can choose to drink other brands of milk or beverage juice!
