Drinking milk on an empty stomach is not a problem for most people. Milk is rich in protein, fat, minerals, calcium, phosphorus, iron and other nutrients, which can strengthen nutrition and help improve immunity. However, for people suffering from lactose intolerance, they cannot fully digest the lactose in milk and drinking milk may lead to nausea, flatulence, diarrhea and other symptoms. Therefore, for this group of people, they may need to choose lactose-free milk or other dairy products, and it is recommended to drink it after meals. Overall, drinking milk on an empty stomach is not a problem for most people, but the decision to drink milk on an empty stomach needs to be made based on each individual’s physical condition and reaction.
