Milk is a common food and does not have the efficacy and effect of medicine, but drinking milk can supplement the body’s protein and other nutrients. Milk protein content of 2.8% to 3.3%, carbohydrate content of 3.4% to 5.4%, fat content of 2.8% to 4.0%, mineral content of about 0.7% to 0.75%, and milk is also a good source of B vitamins, drinking milk in moderation can be supplemented with the above nutrients needed by the body, to maintain the normal physiological function of the body. However, milk is only a kind of drink with high nutritional value, not a medicine, so it does not have special effects. People who are allergic to dairy products are not allowed to drink milk as it may induce allergic symptoms such as cough and rash. In addition, milk contains a lot of lactose and should not be consumed by those who are lactose intolerant. Although milk has certain benefits, it should not be consumed in excess, otherwise it will easily aggravate the burden on the stomach and intestines, causing abdominal distension and other symptoms.
