What's more, the things that the nagging Chu Lihua said are all scientifically based?
Now the "bricks" are actually not credible, these people are really hopeless.
Liu Xingting's voice started again, and Qing Yunfei listened carefully, trying to find some flaws.
¡ª¡ª"Logically speaking, if Zhang Chenyu's research is true, then what food provides to the human body is not only simple nutrients, but also biological information that can affect the operation of the human body.
In this case, the relationship between food and the human body becomes very complicated.
For example, is there really a biological basis for the phrases "eat what you eat" and "replenish your body with form"? Is it because what food people eat will be affected by the special micro-RNA molecules in these foods, so the differences between people and between groups of people may be caused by the different things they eat?
Also, are genetically modified foods more dangerous? After all, in addition to natural micro-RNAs, there may be artificially formed micro-RNAs playing unpredictable roles"
Liu Xingting's words attracted everyone's attention, and they listened intently as if they were holding their breath.
¡ª¡ª"This very counter-intuitive and even somewhat sensational research immediately caused various controversies and challenges. Technically speaking, rna molecules are a particularly fragile chemical substance, and many people simply do not believe that the tiny rna in rice The rice remains intact during the steaming process, and it can also pass through the human digestive tract to be completely absorbed.
Some people also questioned that the micro-RNA of rice that Zhang Chenyu and his team detected in the human body may be the result of contamination of the test samples.
In all fairness, I myself was skeptical of these findings. After all, the mainstream understanding of biology has always been that food will be completely decomposed and broken, and then absorbed and utilized by the human body in the simplest form;
After all, micro-RNAs in food can directly interfere with human body functions, which is basically just the opinion of Zhang Chenyu's laboratory. You know, an unwritten rule in the scientific community is that extraordinary claims need extraordinary evidence to support them.
In the face of these doubts, in the past ten years, Zhang Chenyu's laboratory has been conducting research in this area.
Ten years have not been in vain. After the results of the research, they published a new paper in the journal "Cell Research", which provides us with very important clues to the truth.
In this paper, Zhang Chenyu's laboratory found that a protein called sidt1 in animals seems to be responsible for transporting tiny RNA molecules from the outside of the cell to the inside of the cell.
On the cell membrane of gastric mucosal cells in mice, the sidt1 protein content is very abundant. More importantly, after deleting the sidt1 gene in the mice, the researchers did find that the efficiency of the mice's absorption of microRNAs in food was greatly reduced.
Starting from these phenomena, they put forward a guess¡ªthe tiny rna molecules in the food may be absorbed in the stomach and then enter the human body to function.
Here is one more long-winded sentence. The reason why humans use mice for experiments is mainly because their genes are highly similar to ours.
Closer to home, why is this study important?
Because before this, at best, we only had some observations and descriptions of phenomena, such as after eating rice, some tiny RNAs that should only appear in rice appeared in the body of the human body or animals.
Even Zhang Chenyu himself may not be able to explain how this phenomenon appeared.
But now we know that without sidt1, animals cannot absorb and use tiny RNA molecules in their food.
This in turn may indicate that under normal circumstances, tiny RNA molecules in food can indeed enter animals, and this process requires sidt1.
When the problem is only limited to observation and description, the two sides of the debate often fall into a deadlock of talking to themselves. You said that you found the tiny RNA of rice in the human body, and he said that he did the same experiment and saw nothing.
As people who eat melons, we don't know who to trust? Even if I did the experiment myself, if Zhang Chenyu's discovery was not repeated, I don't know if there is something wrong with my experimental operation.
However, after discovering the protein sidt1, scientists can directly verify and expand Zhang Chenyu's discovery.
For example, I can study the protein sidt1 to see if it can really transport micro-RNA molecules and how it is transported;
You can also go to see if the human body lacks sidt1, will it not absorb micro-RNA;
He can also check to see if there is anyOther tiny RNA molecules can also be transported by sidt1
For the first time, this controversial field has a chance to be quickly inspected by a third party, so as to draw a final conclusion.
Of course, I still have to emphasize that I am still skeptical about whether micro-RNA in food can really enter the human body and interfere with human body functions.
Still the same sentence, extraordinary statements require extraordinary evidence. We often say that "proof alone cannot stand", and repetition and proof from third-party laboratories are essential.
However, we might as well imagine first, if this theory is really confirmed, what does it mean?
At least we can say that the relationship between organisms on earth is far more complicated than we once knew.
Just talk about a simple food chain - sheep eat grass, people eat sheep, and after death, the body decomposes and is absorbed by the grass.
Traditionally, it is believed that in this process, what is passed between species is nothing more than various chemical substances and energy.
But from a new perspective, through micro-RNA molecules, and possibly other chemical substances, species are actually transmitting more refined and rich biological information, and it can even be said that species are in direct dialogue.
When the sheep eat grass, the tiny RNA in the grass may directly interfere with the life of the sheep;
When people eat sheep, the tiny RNA in the lamb may interfere with the activities of the human body;
After a person dies, the tiny RNA in our body may also affect the state of microorganisms and plants in the soil.
If all this is confirmed, the earth's ecosystem can really be regarded as an organic whole, and the relationship between human beings and the environment is far from being as simple as obtaining and using. Perhaps in a sense, the human world outlook will be reshaped.
Of course, before imagining all this, let's wait patiently for further research from more laboratories.
At least, judging from the current progress, there is still a certain scientific basis for 'what to eat and what to eat'.
However, the highlight of what I bring to you today is not 'Eat what you eat', but 'Sincerity leads to spirit'! "(Remember this site URL: www.hlnovel.com
