Recently, the discussion on the issue of food additives has become a hot search, especially the magical saying of the young man Fei Ge of Northeast China, "It's all about technology and hard work, buddies", which has become popular all over the Internet. It's quite popular after hearing it, and I want to immediately smash those bad merchants who use "technology and hard work" to make money.
Of course, many businesses also expressed their grievances and felt that they had done nothing wrong. This must be a slander by their peers. For example, Haitian Soy Sauce said that all products meet the requirements of relevant standards and regulations in my country, and relevant personnel must be held accountable for legal responsibilities.
htmlOn October 6, China Food Industry Association issued a document, saying Haitian and calling food additives, emphasizing that, "The scope and limit value of food additives stipulated in my country's current national food safety standard "GB2760 Food and Additives Use Standards" are proven to be safe and reliable after scientific research and risk assessment. Products produced by enterprises in accordance with the standards will not cause harm to consumers' health."
On the one hand, the majority of consumers are excited and demanding that the country stop the abuse of food additives by merchants, and on the other hand, the food industry chain, that is, the food suppliers complain, saying that their reputation has been damaged and their business has plummeted, and they have become the biggest victim.
What should I think about this?
Our current food, as long as it is not a three-no product, there is an ingredient list on the outer packaging of the food, and the ingredients with the highest content are written at the front, and so on, all ingredients must be written on it, and this must be done. This is a mandatory regulation of the country. The names in the ingredient list are strange, and they are obviously not the foods we can usually contact, and they are basically food additives.
When it comes to food additives, the topic will naturally extend to pesticides and fertilizers, plant hormone , as well as hormones and antibiotics for feeding animals, as well as genetically modified animals and plants. Although these are used in plants and animals, they will eventually be eaten by us humans. They are just intercepted by one or several biological channels, and they still have some intake of the human body.
As time goes by, people have gained more and more knowledge about these additives used in plants and animals. Some of them used to think are harmless to people, some of them have now been proven to be harmful, some of them have only a little harm to people, some of them have now been proven to have another harm, and other reports such as those are emerging one after another, constantly appearing in scientific journals, newspapers and magazines, and it is no longer surprising.
. These constantly exposed harms to the human body are only the tip of the iceberg of all added species, but the tip of the iceberg of all the harm of a certain additive. In other words, there are still the harm of most types of additives. We have not studied it yet. Most of the research on the harm of a certain additive, and we have not yet been involved in most of the research on the harm of a certain additive. Why do you say that? Is this a bit alarmist? I'm afraid it's not true. From a scientific point of view, this is the fact in reality we are in.
The creatures in nature have evolved for more than 3 billion years, from single-cell organisms to multi-cell organisms , from plants to animals, from invertebrates to vertebrates, from egg animals to mammals, from non-intelligent organisms to intelligent organisms, that is, humans. In general, evolution is moving in an increasingly complex direction, that is, from low to high, and humans are the highest and most complex species of organisms on earth.
The complexity of organisms is unimaginable. Humans can make the most sophisticated EUV lithography machines, which can allow large aircraft to go into the sky and have the ability to build giant buildings, but they do not have the ability to create a living cell from scratch, the simplest, most basic structure of all organisms.
Even after the development of quantum mechanics , people cracked the essence of chemistry; after the development of molecular biology , people have seen some internal mechanisms of organisms, and they still have no way to create even a cell.
The reason is that humans still know nothing about the details, even the principles. What is the approximate proportion? At present, at least 99% of the details are not clear, and most of the details are unheard of, and we may not even know the principles, let alone understand them. This is just a matter in a cell.
We all know that the human body has about 40 trillion to 60 trillion cells. Each cell has a set of the same DNA 2 in the nucleus of . The human body's DNA consists of 23 pairs of 46 chromosomes. On all these chromosomes, there are about 3 billion pairs of 6 billion bases . There are only 4 types of so many bases. They pair in pairs whenever they have the chance, and the paired objects are absolutely fixed and there will never be any errors.
For example, in " Dream of Red Mansions ", the four major families of Jia Shi, Wang and Xue in " Dream of Red Mansions ", the more than 1 billion men and women in the Jia family only intermarries with more than 1 billion men and women in the Wang family, and they are paired with each other and never intermarry with outsiders, and of course it is even more impossible to have homosexuality; the more than 1 billion men and women in the Shi family also intermarry with more than 1 billion men and women in the Xue family, and they never intermarry with outsiders. This lasts forever, without exception.
These 3 billion pairs of bases are arranged in a row. If they are connected together, they are about 2 meters long, but they are very thin and so thin that they can be wrapped in a cell nucleus with an average diameter of about 5 microns. One meter is equal to 1 million microns. It is like putting a 400-meter-long kite string into a space that is only the size of a steel ball-point pen tip, and imagine what a difficult challenge it is.
Usually, this DNA is always combined with two chromosomes in pairs. There are 23 pairs in total. Only when it is needed to be used, or when cells proliferate , will it be divided into two and replication work. During replication, it is the same as the case of intermarriage between Jia, Shi, Wang and Xue families. After replication, it quickly returns to the paired state. The replication work of DNA involves 3 billion base pairs , which are all completed in a small nucleus in a very short time (no more than an hour). Imagine the difficulty of such a project.
Let’s take a look at the complexity of cell functions and talk about how protein is synthesized in cells. The process of
is like this. When the DNA in the cell nucleus needs to be copied, the paired chromosomes are temporarily separated under the action of enzymes to pair with new bases. Some of these 6 billion bases are marked as non-replicable. Just like a single production factory can only obtain part of the total design drawings, and the drawings obtained by different production factories are different. A single cell can only copy part of it and can only obtain the part that belongs to it. This kind of gene fragment replicated based on DNA is called RNA. After copying, the DNA is quickly combined in pairs.
What is the proportion of the RNA of each cell that replicates the 6 billion bases in DNA? How many, there are many, and the various types of cells vary greatly, with the proportion ranging from 10% to 90%.
So how many types of DNA fragments are there, that is, how many types of RNA are there, and they are also very different, with millions of types. After all, there are billions of bases. The lengths of these RNAs are different, and the number is astronomical, because RNA can replicate itself.
Some of these kinds of RNA have been proven to have functions, some guesses have functions, some think that there is probably no function, and more (more than 99%) RNA has not been studied, and people know nothing about it.
There is a type of RNA function in this, which is used to synthesize proteins. The RNA used to synthesize proteins just copied will be pruned to remove the "useless" bases interspersed with it. The cut "useless" RNA fragments are long and short, some have functions, some have no functions, and some are unclear, forming part of the millions of RNAs in the cells.
trimmed RNA is called messenger RNA (mRNA), which is equivalent to the design drawing of proteins. Next, we have to rely on a transport RNA (tRNA) to stick to amino acid . Amino acids are the raw materials for synthesis of proteins. There are 20 different types of amino acids in total. Different proteins and the formulas of amino acids are also different. Therefore, the formula for the amino acids that transport RNA needs is the same as the amino acid formula required for messenger RNA. Otherwise, proteins cannot be synthesized. This is easy to understand. It is hard to cook without rice, right?
transport RNA is equivalent to a truck that transports raw materials according to the formula. At this time, there is also a production process, which is ribosomal RNA (rRNA). The transported amino acids are arranged and combined according to the design drawing of the messenger RNA, and finally synthesize the required protein. Of course, ribosomal RNA must also be used in conjunction with the messenger RNA, with the same amino acid formula, otherwise the required protein will not be synthesized.
ribosomal RNA can build about 200 amino acid molecules per second, and there are about 10 million such ribosomal RNAs in a cell, which means that each cell can produce millions of protein molecules in one second. This efficiency is amazing!
What is even more incredible is that the yield rate of protein produced in this way is extremely high. Normal cells produce trillions of protein molecules, but none of them contain defective products. What is even more amazing is how many proteins are produced. The control is incredibly accurate, with an error of no more than one hundred billion.
The human body has various proteins. According to the gene encoding, there are more than 20,000, or about 24,000. Almost every protein has several variants, and only a few have no variants. Such various types of proteins are synthesized efficiently, high-quality and just right in the cell.
Synthetic protein is just one of all the functions of the cell. In addition, cells can also produce themselves. This process is called cell division , or cell proliferation, especially cell proliferation control of the quantity, and its accuracy is no less than that of synthesis of proteins.
This is why our hair always grows longer at this speed, why our body organs grow into a certain shape, why so many epidermal cells fall out every day, no more or less just enough, some of which depend on the cells' precise control of the number of protein synthesis and the number of cell proliferation.
Imagine if this cell is a production base, what kind of unattainable high-tech technology is? If tens of trillions of cells are still organically combined to form various super functions, this makes us feel desperate now. How to do
cells is almost confused at present, and only caught a little clue, and then guessed and came to some "conclusions". Looking at this type of scientific paper, uncertain modifiers are used a lot, such as what are the possibilities, maybes, probably, etc. Some scientists simply say that I can't figure out the reason, and I can't talk nonsense, but I just found this phenomenon.
Now people only know that this is roughly the case. Our cells contain thousands of chemical substances, protein macromolecules and enzymes ( biocatalyst , some of which can speed up the reaction, while others are the opposite), as well as DNA containing 23 pairs of chromosomes and millions of RNAs of different lengths. They follow the common basic rules of the universe, collide with each other, combine with each other, interact with each other, and create some results. All these results form such an extraordinary masterpiece, namely cells.
is like an hidden box . There are all kinds of raw materials such as brushes, easels, canvases, pigments, palettes, etc. for painting. The proportion of the raw materials has been automatically adjusted. As long as we shake this hidden box, we can get a perfect oil painting. The key lies in the proportion of the raw materials. It cannot be more or less. It will almost destroy the beauty of the painting and even lead to the complete failure of the painting. As for how this painting was drawn, I don’t know.
And the cell is such a secret box. The reason why we cannot figure out the mystery here is because we still don’t know what the most basic rules of the universe are, or we know very little, which is probably something that we have to admit.
If the quality of our cells is slightly worse, the consequences will be very serious. In mild cases, there will be missing arms and broken legs, or various deformities and disabilities, and in severe cases, there will be life-threatening; if the quantity of cells produced is out of control, it will cause another serious situation. There are two mechanisms in which the number of cells produced by
is out of control. One is the positive feedback mechanism and the other is the negative feedback mechanism. The positive feedback mechanism is that as the out of control occurs, more strengthening factors will be generated, resulting in more out of control until it finally collapses; negative feedback means that after the out of control occurs, more inhibitory factors will be generated to prevent the continued out of control and slow down or retreat.
Out of control of cell production includes two situations: abnormal increase in cell production and abnormal decrease in cell production.
The abnormal increase in the number of cells is what we often call tumors. Some tumors will disappear on their own, some will stop growing, and some will continue to grow. Some will be benign. In addition to how much it grows, it is basically harmless to the body, and some are malignant. Not only is it an out of control under the positive feedback mechanism, it keeps growing, but the quality of this cell is bad and the function of the cell has also changed. This is cancer. The abnormal decrease in the number of cells in
is what we often call aging. Aging is almost all positive feedback mechanisms. This is the result of natural selection. It is probably because immortal organisms are not as competitive as organisms with birth, old age, sickness and death, so aging develops in the direction of irreversible (involuntary death).
means that once aging begins, it cannot stop at all, and over time, it will accelerate aging until the organs completely lose their function and the organism dies.
If you want to reverse aging, you must prevent the positive feedback mechanism. However, as we said earlier, people cannot understand the principle at all, so they can only do it. If you are not careful, it will cause abnormal increases, and it will create a tumor, and it is a tumor with a positive feedback mechanism, and the tumor is the prelude to cancer.
In this sense, what we call anti-aging drugs now are fine if they are not really anti-aging. If they really have anti-aging effects, they are very likely to be highly effective carcinogens, which may delay aging, but they are more likely to occur. We either die from aging or cancer, and it depends on which one of them, aging or cancer, first.
Theoretically speaking, if we understand the most basic rules of our universe, understand all the operating mechanisms of living organisms, and have strong enough regulatory capabilities, we can achieve immortality, but it is still too far away.
After saying so much, I can finally return to the beginning of the topic, which is how to look at food additives. This question also applies to chemical fertilizers and pesticides, hormones and antibiotics, various drugs, catalysts, genetically modified animals and plants, etc.
All these things, no matter what path they pass, enter our body, may enter the cells, and may collide, combine, and even produce results with various substances inside, which will affect the exquisite balance in the cells.Once
is unbalanced, it will lead to a decrease in the quality of cell production and the quantity will be out of control, which will have certain possibilities, which will cause serious consequences, and may also be a little mild, just to accelerate aging or increase the possibility of tumors, and it may not be felt in a short period of time.
The so-called safety and harmlessness of food additives is only relative. We don’t know or know whether it is safe or harmless, so we think so, but logically speaking, this is not true.
is like saying, I don’t know if this mushroom is poisonous. If you first draw a conclusion that it is non-toxic, safe and harmless, it may kill people. I can only say that it is considered poisonous for the time being. Don’t eat it first. Once you figure it out and make sure it is non-toxic, it will not be too late to eat it again. This is better. Is this the truth?
The human body is composed of tens of trillions of cells. It is an extremely exquisite and subtle incredible machine. It has powerful functions and has strong adaptability to the outside world, but it is very fragile inside and cannot withstand a little tossing. It is best to let it go. There is no need to do it. Don’t intervene in humans, because you don’t have the ability, you will only lose sight of one thing and be in a dilemma. This is the reason.
my country's economy is developing rapidly. It was not enough to eat more than 60 years ago. It just abolished the planned distribution system of food 30 years ago. It only entered the stage of relative food and clothing 20 years ago. It only entered the stage of relatively abundant food and clothing 5 years ago. This often causes the country's policies to lag a little. Moreover, the foundation of this stage of prosperity is still unstable, and it may decline, such as natural disaster , changes in the international situation, etc.
So we can't say that some people are rich, so we immediately require strict control of food additives, including other additives, and also consider the eating problems of another group of people. What can we do? Under the conditions, we should choose food without additives and zero pollution as much as possible. If there are food additives, we should not eat them, and try not to eat them.
Economically, there is a motivation for production when there is demand. When the demand for food without additives increases, more merchants will produce it to meet market demand. Gradually, more and more food without additives will become more and more. Then, the control will be stricter, and it will be natural.
Regarding the issue of food additives, I don’t know if you are satisfied with this, so you can leave a message to discuss.
