There should be a few adults who have consumed (tasted) breast milk, but it is still surprising that it has become a business. Regardless of the fact that this business of hiring a nanny to sell breast milk is suspected of being illegal (the Health and Family Planning Commission has issued a "Response that Human Breast Milk Cannot Be Managed as a Commodity"), but as far as nutrition is concerned, there is no need for adults to pursue breast milk for health. Despite the mystery of the human health value of human milk, in fact, with a little analysis, the so-called conditioning is nothing but a cloud.

　　 Compared with milk of the same weight, human milk has a lower protein content (1.2% vs. 3%). The advantage of human milk protein is that the proportion of whey protein is higher than that of milk (70% to 20%), which is very important for babies, because whey protein not only has higher nutritional value (but also supports the rapid growth and development of the fetus), and Easy to digest (more suitable for infants with incompletely developed gastrointestinal tract). But for adults (no longer growing and developing, with complete digestive function), the special advantage of human milk containing more whey protein no longer exists. And, if you care about whey protein, you might as well choose infant formula or take whey protein powder.

　　Human milk calcium content is not as much as milk, only equivalent to 1/3 of milk. The advantage of human milk calcium is that the absorption rate is higher than that of milk, that is, it is easy to absorb. Of course, this is also aimed at the infants and young children''s incompletely developed gastrointestinal tract, and milk is the single or main food. For adults, the recipe is more complicated, the intestinal absorption capacity is stronger, drinking milk can get enough calcium, there is no need to chase expensive human milk.

　　 Through the above analysis of protein and calcium, we can see that the real advantage of human milk is easy digestion and absorption, which is particularly important for infants and young children, not important for adults, or even outweigh the gains. Another advantage of human milk is that it has more complete nutrients than milk, such as DHA, lutein, nucleotides, etc. This is especially important for infants and young children who have a monotonous diet (with milk as the single or main food), but also for adults Not so important, because adults can get these nutrients through fish, vegetables and other foods (otherwise how do women "make" breast milk?). If you have to keep up with infants and young children, then the use of infant formula is more desirable, because most infant formulas also contain these nutrients.

　　 For adults, human milk has little advantage over milk in many respects, and almost no advantage compared to formula milk. But human milk has an advantage that formula milk powder cannot replace or simulate, that is, it contains active immune substances, such as secreted immunoglobulin A (sIgA), lactoferrin, lysozyme and so on. Among them, sIgA is the most important, and it is the main antibody of the body''s mucosa against local infection and immunity. However, sIgA in human milk can only play a role on the surface of the intestinal mucosa after it enters the intestine, improving the intestinal mucosal immunity. Generally cannot enter the blood, so it has no direct effect on the immunity of other parts (such as lung, urinary tract, etc.).

　　However, after all, the gastrointestinal tract is one of the main channels for bacteria and viruses to invade the human body, so sIgA in human milk is harmful to infants (incompletely developed intestinal tract) and critically ill patients with gastrointestinal tract damage Has a certain meaning. In clinical practice, there have also been attempts to feed critically ill patients with human milk in order to increase gastrointestinal mucosal immunity and increase nutrition. However, with the exception of pediatric patients, there are few reports of success, and there is a lack of convincing evidence-based medical evidence to support this practice. Moreover, the lactose problem should also be considered in practical application, the content of lactose in human milk is higher than that of milk. A considerable number of adults cannot digest lactose, causing bloating, diarrhea, abdominal discomfort, etc. ("lactose intolerance"). Critical patients with intestinal damage are more likely to suffer from lactose intolerance, or the situation is more serious, so it is not recommended to give milk or nutrient solution containing lactose. At this time, human milk is taboo rather than recommended. In clinical practice, such critically ill patients can overcome difficulties through specialized enteral or parenteral nutritional support.

　　 Another real advantage of human milk is its extremely low sensitization, which means that no allergies will occur. This is hard to find for infants and young children, and adults who are allergic to milk protein (often allergic to animal milk such as milk sheep, buffalo milk, and formula milk) can also be used. However, adult recipe milk is not indispensable. Adults who are allergic to milk protein can increase their intake of meat, eggs, fish, and soy products, even if they do not drink any milk, they can obtain comprehensive nutrition.

　　As we all know, eating health products often has a "psychological suggestion effect", that is, if you believe that a certain product has a wonderful effect, then you may feel the effect after taking it. Will human milk also have the effect of conditioning the body? This can only be answered by human milk consumers. Personally, I don’t like it very much. Eating human milk should not make people psychologically “shrink” into the era of breastfeeding!
