How can rice lower blood pressure?
In 2020, the Institute of Botany of the Chinese Academy of Sciences published a transgenic rice study in the authoritative journal "Agricultural and Food Chemistry", which found that when the model mice with hypertension were given transgenic rice containing transgenic rice that can always be blood vessel strained to convertase inhibitory peptides (ACEIPs), the blood pressure of rats was significantly reduced.
The most surprising thing is that there were no obvious side effects during the trial.

This rice plant is not a common genetically modified vegetable on the market, it was implanted by the researchers with a special gene, which is linked together by 9 ACE inhibitory peptides and a vasodilator peptide.
Figure: Comparison of systolic blood pressure changes in rats over 7 weeks
As can be seen from the above figure, after the researchers fed the protein extracted from the genetically modified rice to the hypertensive rats for 5 weeks, the blood pressure of the hypertensive rats dropped significantly, and there was no significant change in normal blood pressure rats. After 2 weeks of normal diet, the blood pressure effect in hypertensive rats was maintained.
In this rat experiment, the genetically modified rice containing ACEIPs (angiotensin-converting enzyme inhibitors) did achieve the purpose of lowering blood pressure, but can this rice that can lower blood pressure be really put into production and planting in China?
This study is based on animal experiments, and is a phase I experiment, and China has a very strict regulatory measures for genetically modified crops, before officially obtaining the safety certificate, it is also necessary to go through several stages such as experimental research, intermediate experiments, environmental whether or not, biological tests, etc.
The study took only 7 weeks and could not meet the consideration of large samples, diversity, and length. Genetically modified rice also needs to undergo more rigorous trial and error, and obtain more powerful data to obtain the possibility of putting it into production.
In the public media, we often see such news: genetically modified foods are toxic; eating too many genetically modified tomatoes causes cancer; the reasons why Americans don't eat genetically modified foods... Every time Xiaojiu goes to the vegetable market, he hears the old mother who buys vegetables and dislikes it again: "This kind of genetically modified vegetable cannot be eaten more, and it is not good for the body." ”
Are genetically modified foods really unpalatable?
Transgenic technology refers to the purposeful transfer of one or more genes of one species into another species and become a new species. What are the benefits of this technology?
For example, a farmer's uncle needs a lot of herbicides to grow crops, and herbicides are very powerful pesticides that can cause residues and even endanger the crops themselves. To solve this problem, scientists implanted a gene that is resistant to the power of herbicides into crops, so that crops become very "resistant." This crop is called a "genetically modified crop."
On the market, common "genetically modified crops" are genetically modified soybeans, genetically modified corn, genetically modified tomatoes, etc., which are genetically modified agricultural products that have passed safety verification.
As a major agricultural producer, China must have a place in genetically modified technology. Since the establishment of the major transgenic project approved by the state in 2008, China's scientific researchers have cloned more than 100 important genes and obtained more than 1,000 patents, ranking second in the world in the total number of patents after the United States.
GM Has reduced the cost of production and increased the amount of production, but GMOs have always been a matter of great concern. Yuan Longping, the father of hybrid rice, once expressed his views on this issue.
He believes that genetically modified organisms can not be generalized, some genetically modified organisms are disease-resistant to insects, called "toxic protein genes", insects eat to die, what will happen to the person who eats? People and insects are not the same after all.
In an interview with Phoenix Finance, Yuan Longping said that genetically modified organisms are the future development direction, scientific measures to ensure food security and increase production, and there is nothing wrong with using genetically modified technology to bring people safe and high-yielding grain. Genetically modified foods are put into production after reasonable research and strict scientific testing.
Wu Kongming, an academician of the Chinese Academy of Engineering, also said that there is a clear authoritative conclusion that genetically modified security is unsafe. Only genetically modified products that have been evaluated for safety can be listed, and the safety of genetically modified foods on the market is equivalent to that of traditional foods.
When shopping in the supermarket, if you pay close attention, you will find that many cooking oils and soy milk are marked with the words "non-GMO".
The State Administration for Market Regulation solicited opinions on the Measures for the Supervision and Administration of Food Labeling (Draft for Solicitation of Comments), which stipulates that food does not use genetically modified food raw materials and must not use "non-GMO" on packaging. Some enterprises use "anti-GMO" to cause social unrest, and unauthorized labeling of "non-GMO" to mislead the public is an improper speculation.
GM Has always been a hot topic, especially in the social network circulated a so-called "GMO identification guide slip-off", which is full of loopholes, there are many stealing concepts, upside down black and white fallacies.
Taking one of the "cherry tomatoes is genetically modified," children are taught not to be greedy. Despite the delicious taste, it destroys the health of the sick. "For example, cherry tomatoes have long been proven not to be genetically modified tomatoes, but wild special varieties, and the cherry tomatoes on the market are artificially cultivated and have nothing to do with genetic modifications.
Genetically modified foods are not as rumored, they are all harmful, and we should polish our eyes and believe in science and facts.
