Drinking milk on an empty stomach is wasteful, easy to have loose bowels and so on. A healthy human body, even liquid food, can be fully absorbed, so it is nonsense to drink milk on an empty stomach and not absorb nutrition.
Some people will feel bloating, discomfort and even diarrhea after drinking milk, which is probably caused by lactose intolerance. You can drink more milk and eat a little bread at the same time, which will alleviate the symptoms. However, if you are allergic to milk protein, do not drink milk.
Milk contains tryptophan, vitamin B and so on, which helps you sleep. However, a cup of 200 grams of milk contains only about 78 milligrams of tryptophan, which is lower than that in soybeans. It is estimated that in order to improve sleep, we need several barrels of milk to change the hormone level of our body. Most doctors think that you can't drink milk on an empty stomach in the morning, because drinking milk on an empty stomach in the morning will affect the digestion of food in your stomach, which will lead to indigestion.
The digestive system can not digest the nutrients in milk better, resulting in milk waste, and even abdominal pain and diarrhea in severe cases. Some doctors think that they can drink milk on an empty stomach. Doctors believe that milk is rich in nutrition, even if it is drunk on an empty stomach, it will not cause side effects, but it should be moderate, but it is forbidden to drink too much milk on an empty stomach. It is best to eat some other food before drinking milk, or you can eat some bread with it. This discomfort will be lighter than drinking on an empty stomach.
Moreover, there is a "blood-brain barrier" between the brain and the blood, which can prevent some substances (mostly harmful) from entering the brain tissue through the blood, and also prevent some beneficial substances, such as tryptophan in milk. To play a role, you need to break through this barrier. Therefore, it is very difficult to drink a glass of milk to help sleep.
For patients with lactose intolerance, drinking milk is not recommended. Drinking milk will aggravate physical weakness and affect sleep because of diarrhea. Warm milk contains leucine and some trace elements, which can soothe the nerves, repair the function of gastrointestinal tract and supplement the nutrition of brain cells, thus contributing to the improvement of patients' sleep.
In order to save trouble or alleviate the bitter taste of drugs, many people will choose to take milk to give drugs. Some substances in milk may react chemically with drugs, making it difficult for drugs to be absorbed; Some drugs will even be destroyed by these substances, affecting the efficacy of drugs.
In addition, milk will have toxic reactions with some drugs, such as tetracycline drugs, which will combine with calcium ions in milk, resulting in drugs not being absorbed. Of course, milk and some medicines are not enough. Of course, this situation is rare. Try not to take medicine with milk or follow the doctor's advice.
The doctor said that drinking milk can't be used to take medicine, because milk is rich in nutrients and will react chemically with drugs, thus reducing the efficacy. In severe cases, it can also cause gastrointestinal discomfort, abdominal pain, diarrhea, abdominal distension and other symptoms. Taking medicine and breastfeeding will reduce the curative effect, make the medicine unable to play its role, and thus aggravate the symptoms.
So, take medicine with warm water instead of milk. You can drink milk 1~2 hours after taking the medicine. Milk is a good nutrient, which can supplement calcium and enhance immunity. Drinking a cup of hot milk at night is good for sleep.
