Xu Yi said: "In fact, Ejiao is a relatively rare item in traditional Chinese medicine, which once had medicinal value but has lost its medicinal value with the change of time. ”

Liu Liping didn't understand this, so she asked, "Why, isn't Ejiao still selling?"

Xu Yi nodded and said, "It's indeed still selling, and the sales are good." Not only Ejiao, but even Ejiao products are on sale, and most of them are still claiming that this thing has the effect of nourishing yin and nourishing blood, and even beautifying and nourishing the skin. However, in the current situation, they can only be used as a selling point of health supplements - and this is still from traditional medicine, and in the current situation, there is not much practical value at all. ”

"Why?"

"You can imagine what the economic conditions were like before. Even thirty or forty years ago, the average person could not eat meat several times a year, and even if they could occasionally eat a meal of tofu, it was considered good, so it can be said that under such conditions, the daily dietary protein intake will definitely be extremely insufficient. Insufficient protein intake can easily lead to anemia, so at that time, it was actually true to say that Ejiao had the effect of nourishing yin and nourishing blood. However, this theory has reached the point where the economic conditions are better and a large number of protein-rich foods are circulating today, and the statement that Ejiao nourishes blood is meaningless. ”

"Ejiao is not easy to prepare, and it is even more troublesome to eat, which has to be broken again, and then soaked in rice wine for a long time before taking it again, which is a challenge for ordinary people, and after soaking for a long time, it is easy to breed miscellaneous bacteria in it, which is possible to eat and diarrhea. If you want to avoid these problems, buy something like Ejiao oral liquid, Ejiao capsules, etc. Naturally, it's simple. It's just that the fat man has talked about the ingredients of this thing before, and you want a bottle of ten milliliters of solution. How much protein can there be in it, and what actual nutritional value can this thing have. A box of ten bottles, at least not sell you for dozens of dollars, and this can't be eaten as a dish? This bottle can be replaced with several boxes of tofu, and if you eat a mouthful of tofu, the protein in it is more than your bottle of oral liquid. Even if you are not afraid of trouble, what if you buy ejiao and use walnut kernels and sesame seeds to make ejiao paste, if you don't have the basis of insufficient protein intake to cause anemia, you can eat this thing, at most, it will play a role in replenishing energy. There is no value of blood replenishment at all, so the fat man said that Ejiao can't replenish blood, which is actually true. ”

The fat man stretched out his hand and patted Xu Yi's shoulder, and said, "In the end, it's the third child, this is the first thing to say, it's clear, it's much better than me." It's no wonder that I look at the pictures of the North Korean army with sharp beaks and monkey gills, which are similar to the people in our old domestic photos, and I think this must be malnourished. What do you think we should do to sell Ejiao wholesale to North Korea?"

Hu Yifei said: "I think it's okay, presumably this can make the three fat emperors of their country happier, and we can also earn foreign exchange through exports." ”

The fat man then asked Liu Liping: "Xiao Liu, and then things like pig's trotters and soft-shelled turtles are said to have the effect of beautifying and nourishing the skin." Seeing her nod, the fat man continued: "Actually, whether it is the hoof tendons, the skin of the meat or the skirt of the soft-shelled turtle, the main ingredient is also collagen. The star called the hemorrhoid. Do you know each other?"

Liu Liping asked: "You're talking about the combination of Supreme Lihe, isn't that a star?" ”

The fat man shook his head. "I can still tell the difference between a combination and a star. I'm talking about hemorrhoids for hemorrhoids, the nucleus of nuclear weapons. Connected is the hemorrhoidal nucleus of hemorrhoids. ”

Liu Liping is white-eyed and fat, which one is this person arranged. "Cut, who knows which one you're talking about, you're really disgusting, which celebrity are you nicknamed here, right?"

The fat man smiled and said, "I'm talking about hard hemorrhoids, and the hardest part of the hemorrhoids is, of course, the hemorrhoids." ”

Liu Liping reacted at this time, knew which one he was talking about, spat lightly, and said: "Dead fatty, you are too lacking in morality, why do you say this, people recruit you and provoke you?"

"It's not to blame anything else, just blame this person for saying that drinking the collagen oral liquid produced by his own factory can achieve the effect of beautifying the skin and producing reverse growth. In fact, I liked this person quite a lot before this, and I didn't have too much lace news after debuting for so many years, and he was generally showing positive and sunny things, which can be called a model artist. But this outdated star, such propaganda misleads consumers, this is a lack of morality. I said that there is nothing wrong with his name hemorrhoids, this is completely a cancer of society, the scum of the entertainment industry!"

Liu Liping nodded: "You are too extreme, I think such a big star can't lie, and he does look young, not to mention that collagen can have this effect, and the amount of collagen in the skin also determines the elasticity of the skin, if you supplement collagen, you will definitely be able to supplement the collagen in the dermis, what's wrong with this." ”

The fat man smiled and turned his head to look at Xu Yi. "The third child, you go. ”

Xu Yi said: "First of all, we can think like this, he has seen Bensi, this factory is newly opened, and he must have never drunk anything from his own factory since he was a child." And the gimmick of collagen health care has only come out in recent years, and even I know it, so you can imagine how deeply rooted this statement is. I just want to know, so many years before he opened this factory, what kind of 'reverse growth' he ate was not a panacea. If he really has this formula and what kind of romance circle is mixed up, just go directly to open a pharmaceutical factory, even if the approval is difficult and slow, there will definitely be no problem in building a pharmaceutical factory. If this is a drug that can achieve the effect of reverse growth, is it afraid that there will be no market, but I am afraid that he will already be richer than the lid?"

"But to say that this collagen has the effect of reverse growth is not only an exaggeration, it should be said to be a relatively despicable fraudulent propaganda. Even if this collagen is really drunk, it is directly distributed under the skin, at most, it can make the skin more elastic and smoother, and it can play a certain role in reducing wrinkles, but at most it makes people look less old, and it has no effect on the aging of other organs and tissues of the body, and people do not live on collagen alone. ”

"What's more, from the perspective of protein digestion, absorption and utilization in the body, taking collagen does not have this effect. ”

"Didn't I say before that skin is for defense. Do you want to block the absorption of macromolecules through the skin? Seeing Liu Liping nodding, Xu Yi continued: "In fact, the digestive tract is the same. The body's absorption of protein takes place in the small intestine, and it is hydrolyzed in the intestine by mixing proteases in the stomach and duodenum. They are then converted into amino acids or short-chain oligopeptides that are not potentially dangerous to the human body before they can be absorbed. ”

"Even oligopeptides, if there are more than three amino acid molecules, it is already very difficult to be absorbed into the bloodstream through guò intestinal wall cells, and as for polypeptides or proteins with more than ten amino acid molecules, this is already potentially antigenic for the human body, which is something that the body also needs to avoid absorbing. ”

"If such large molecules are not hydrolyzed, then the human body would rather waste them and let them enter the lower gastrointestinal tract to be broken down by bacteria than let them pass through the digestive barrier. into the body. Speaking of which, I want to ask you, few adults have allergies to food, do you know why?"

"Is it allergic when I was a child, and I rarely eat it when I grow up? ”

"That's right, but in fact, many adults who are allergic when they are young no longer choose this kind of food, which naturally makes him less allergic, which is definitely a factor. ”

"In fact, especially infants and young children, because the digestive glands are not well developed, the secretion of protease is insufficient. In addition, the peristalsis function of the gastrointestinal tract is also poor, so it is easier for large molecules of protein to have the opportunity to contact the wall of the small intestine, such as some casein and lactoglobulin contained in milk are now recognized allergens, which is why children under half a year old should never drink fresh milk. Drinking milk can easily cause these to enter the body and cause allergies, and if there is lactose intolerance, this can even lead to diarrhea. So even if the milk powder is no longer safe, I want to buy my own cows to feed my children. In fact, it's all nonsense, don't have such ridiculous thoughts in the future. ”

"These amino acids and oligopeptides are transported into the cell so that they can synthesize the corresponding proteins in the body. So even if you absorb collagen, you don't guarantee that you can synthesize collagen in the body, let alone guarantee that the ingested amino acids will be distributed under the skin, it can be said that as long as you ensure the amount of protein intake, the collagen content depends more on how much collagen your dermis can synthesize, and how much can be retained, these only depend on your genes, age and physical state, not at all you can achieve reverse growth by eating a collagen, not to mention collagen, even if you eat the least whey protein, you can't, these things, too, have to be broken down to be absorbed by the body。 ”

Therefore, collagen can not only not be absorbed by the skin, in fact, it can also not be directly absorbed by the digestive tract, only lose its structure and be converted into small molecules of amino acids or oligopeptides can be absorbed and utilized by the human body. ”

"More strictly speaking, the homology of this collagen is also very high, a wide range of sources, but it is an incomplete protein after all, no matter any source of collagen, at most it only contains eighteen kinds of amino acids, lack of tryptophan and cysteine, of which cysteine is not a big problem, the human body can synthesize itself, but tryptophan must be ingested to supplement, so if in order to supplement tryptophan, then you must supplement other proteins, so relative to complete protein, this collagen can be said to be an inferior protein, you can like the taste of chicken feet or pig's trotters, but don't believe that these things are really going to be more nutritious than pork and chicken. ”

The fat man looked at Liu Liping and said, "Yes, if collagen really has such a good effect, then wouldn't it be more able for me to eat bird's nest shark fin, which is also rich in collagen?"

"These things are all delicacies from the mountains and seas, and the selling price is very high, you are really a local tyrant. ”

The fat man smiled and said: "Who said that the hemorrhoids' protein is known as a bottle of 10,000 milligrams of collagen, and I laughed when I saw this mark, why didn't he use micrograms and picograms, but it could be several orders of magnitude higher, and the content was even more terrifying! Even if a box of 30 bottles is only 300 grams of collagen, it sells for more than 1,000 yuan, does anyone know how much food-grade collagen is sold for?" Now, even if the price of imported food-grade collagen is only 200 yuan a kilogram, the price and profit are much stronger than bird's nest shark fin. (To be continued......)
