Drink milk on an empty stomach
The reason why people believe that they can't drink milk on an empty stomach is because they believe that drinking milk on an empty stomach is harmful. There are various opinions on the Internet. (Summary) Maybe there are the following points:
Hazard 1: Drinking milk on an empty stomach hinders digestion.
The water content in milk is relatively heavy. Drinking milk on an empty stomach will dilute the gastric juice, which will lead to the food not being well digested, and the nutrients in milk cannot be well absorbed. When milk is drunk in the stomach, it has no time to stay and is directly washed into the large intestine.
Therefore, you must not drink milk on an empty stomach in the morning, or you will drink it for nothing. No matter how expensive the milk is, the body can't absorb its nutrients. The milk just goes through the motions in our bodies.
Hazard 2: Drinking milk on an empty stomach is not good for the stomach.
Don't drink milk first when you get up in the morning. You should eat something to pad your stomach first, and then drink milk. If you drink milk first, it may lead to flatulence. If you drink milk, flatulence is definitely caused by drinking milk on an empty stomach. Some people who have a bad stomach may even lose diarrhea if they drink milk on an empty stomach. Have you ever lost this situation?
Hazard 3: Drinking milk on an empty stomach will produce harmful substances.
There are many high-quality protein in milk. If you drink it on an empty stomach, it will be discharged from your stomach quickly, and then it will be decomposed into calories and consumed. However, some amino acids are discharged into the large intestine before the small intestine can absorb them, and eventually harmful substances are produced in the large intestine, which brings a certain burden to the human body. Can you drink milk on an empty stomach?
In view of the above three hazards, the relevant explanations and suggestions are arranged as follows:
Truth 1: The human body will consume lactose and fat first.
The nutrient composition of milk is _% water, 3%-4% protein, 4%-5% lactose and 3%-5% fat. That is to say, besides precious protein, there are many other substances such as carbohydrates and fat.
After milk enters the human body, it is only people's guess that it passes through the intestine without stopping. The digestive tract is not a funnel. Even if the gastrointestinal peristalsis function is strong or the digestive enzyme level is slightly low, most of the milk nutrients will be absorbed, and it will not be wasted.
People who say that "protein was first converted into heat and consumed" don't understand the human mechanism. In fact, the human body is quite intelligent. Healthy people who drink milk will consume lactose, fat, etc. first, and then convert it into calories, and then it is protein's turn to convert calories.
For example, infants, especially those within 6 months, drink milk on an empty stomach. Breast milk is the milk with the most complete nutrients. Didn't they grow up by absorbing nutrients from it? They can, why can't adults? "Besides, the first bite is to drink on an empty stomach, but the second bite is not!" He Yingxi thinks, really don't think too much.
Truth 2: Drinking milk with loose bowels is due to lactose intolerance.
The discomfort after drinking milk disappears. In many cases, it is not due to fasting, but lactose intolerance.
There is lactase in the human intestine. From children to adults, the level of lactase will continue to decline, and those who do not always drink milk will drop faster and more. Most people never drink milk after weaning in childhood, and the habit of "drinking a glass of milk every day" has not been formed in adults. In case of sudden milk drinking, because there are not enough enzymes to decompose lactose on time, sugar may disappear and remain in the intestine to cause hyperosmotic state, and because of the increase of liquid, it will cause diarrhea.
In fact, this shortage of lactase can be solved by "desensitization" drinking. That is to say, people who are not used to drinking milk every day and have experienced lactose intolerance can start by drinking 50 ml of milk every day for several days, and then increase it to 100 ml and 150 ml, similar to desensitization therapy. After gradually increasing the amount, most people can drink 250 ml-300 ml of milk every morning.
Of course, there are exceptions. Some people really can't drink milk. We will explain this problem to you later.
Truth 3: Drinking milk on an empty stomach will not produce harmful substances.
The nutrients ingested by the human body are mainly digested in the stomach and absorbed in the small intestine. Milk will become a clot in the stomach after drinking it, but it will not affect digestion and absorption. After entering the small intestine, most nutrients will be absorbed, and the waste that is not absorbed will enter the large intestine. Intestine contains a large number of flora. Under normal circumstances, most of these bacteria are beneficial to human body. They can synthesize various vitamins necessary for human growth and development, synthesize essential amino acids from protein residue, and promote the absorption of minerals such as iron, magnesium and calcium. Therefore, not all substances entering the large intestine will be decomposed by bacteria to produce harmful substances.
There are indeed people who are allergic to drinking milk, which is a kind of allergy in protein. If the symptoms such as rash and papule disappear after drinking milk, you need to see a doctor for diagnosis. Especially for infants, if protein is allergic, even the mother's milk can't be fed, so it is necessary to switch to amino acid formula. In this situation, "desensitization" drinking method cannot be implemented, and even dairy products such as yogurt can't be eaten. The safest way is to avoid protein's intake.
