For patients with cold and fever, it is best to reduce the intake of milk. When the human body feels external evil, the cold will visit the human skin and meridian tissues, which will deplete the Yang energy of the human body, and the human body will mobilize the positive energy and stomach energy to resist the evil, and the stomach energy is also slowly depleted at this time. At this time, the function of the gastrointestinal system is in a low state, and the stomach Yang is also insufficient. Milk is a high-protein substance, if you drink milk during a cold and fever, you will also be prone to slow digestion and absorption of protein and other nutrients, and in serious cases, you will also experience various uncomfortable symptoms such as gas, abdominal pain and diarrhea, and the nutrients in milk will not be easily absorbed. In addition, the stomach and intestines also need a lot of stomach gas when digesting these nutrients, which will also indirectly damage the righteousness that resists the evil going out, thus not conducive to recovery from the disease. If you want to drink it, it is recommended not to drink cold milk, not to drink too much, and not to drink it if you can, so as not to delay the disease. Milk is a good tonic drink, but it is not recommended to take it during a cold and fever to avoid gastrointestinal flatulence and other intestinal discomfort.
