It is not good to drink milk on an empty stomach. The main reasons are: firstly, it is easy to cause lactose intolerance and diarrhea; Secondly, the body's absorption efficiency of milk is not high, because the speed of milk passing through the gastrointestinal tract is too fast, and whether it is absorbed or not, it has been excreted. Therefore, it is best to eat milk first, put it last, or drink milk while eating, which will help the body absorb the nutrients of milk and improve the tolerance to lactose.

Matters needing attention in heating milk

For fresh milk, it is best to boil it with fire, and the boiling time should not be too long, preferably not more than 3 minutes.
