A few days ago, the Internet circulated that "the consumption of genetically modified soybean oil is more likely to suffer from cancer and infertility," drawing a lot of media reprint. A person in the industry who has worked in the food industry for more than two decades pointed out that there is a correlation between the consumption of genetically modified soybean oil and the incidence of cancer. How should he view this view? A few days ago, CCTV reporters interviewed many experts such as Wang Xiaoyu, deputy secretary general of the Soybean Association of Heilongjiang Province, and explored the relationship between genetically modified soybeans and tumors.
Supporters: Genetically modified soybean oil is susceptible to tumors
Representative: Deputy Secretary-General of the Soybean Association of Heilongjiang Province Wang Xiaoyu
Wang Xiaoyu said in an interview with reporters a few days ago: Seeing the “2012 China Cancer Registry Annual Report†data, it tells us that the incidence of cancer in China continues to increase, and the regional characteristics are very obvious. When these regional characteristics were analyzed, it was also found that the domestically occurring tumor area and the consumption area of ​​genetically modified soybean oil were highly correlated. The provinces of Hunan, Hubei, Guizhou, and Zhejiang are mainly based on edible rapeseed oil. Heilongjiang is a region that consumes domestically produced natural soybean oil, is not an area of ​​genetically modified soybean oil, and is not a province with high incidence of tumors.
Wang Xiaoyu also believes that geographical and environmental factors, the geographical distribution of chemical elements, pathogenic biological communities, and spiritual customs will not lead to high tumor concentration.
Opposition: GM soybeans are used to squeeze oil
Representative: Zheng Fengtian, Professor, School of Agriculture and Rural Development, Renmin University of China
Zheng Fengtian, professor of the School of Agriculture and Rural Development at Renmin University of China, believes that the incidence of cancer in our country is really improving, but it contains many factors, especially the development of the original industry, soil pollution of township enterprises, and water pollution, which may be the core The reason is that there is no causal link between this and genetically modified soybean oil.
Zheng Fengtian introduced that, for example, in this area, because he eats genetically modified soybean oil in this place, he does not eat in another place. Actually, it is not. Our country’s market is actually highly marketized and what products are on the market. However, this problem has been thrown out and it is also very good. We really should pay long-term attention to the research on the impact of human consumption of genetically modified soybeans.
Zheng Fengtian believes that genetically modified soybean oil is not scary: First, we have eaten 16 years of genetically modified soybean oil so far, basically did not see some unsafe things between them. The core is the second one. In fact, the core of the current GM soybean is BT protein, which is mainly used for insect resistance. This kind of BT protein, as our country stipulates, all imported soybeans can only be used to squeeze oil and make feed. Actually, BT protein is used as waste residue in the process of oil extraction, which is removed as feed, and human consumption of edible oil is not Contains BT protein.
Zheng Fengtian believes that although there is no problem with genetically modified soybean oil, foods such as tofu and soybean curd should be made from non-genetically modified soybeans in the northeast. This must be adhered to.
Many experts pointed out that because soybean production is only one-third of that of corn and rice, and the yield is relatively low, many of the farmers in China who originally cultivated soybeans are now replanting corn and rice, and genetically modified soybeans do not love insects and the yield is high. At the same time with price advantage.
Liu Jingliang, director of the information department of the Fairview Land and Grain Wholesale Market, said that soybean oil accounts for 60% to 70% of the entire edible oil variety, and the ratio of genetically modified soybean oil to soybean oil can reach over 90%. The transgene product expresses a protein, which should be said to have been removed in the middle of the various processes of soybean refining. Therefore, what consumers are worried about is that the situation of genetically modified products remaining in the middle of soybean oil is basically non-existent and can be assured. According to CCTV
The difference between genetically modified soybeans and non-genetically modified soybeans
1. Genetically modified soybeans:
Obviously oblate or oval, dark yellow color, and the obvious difference with domestic soybeans is that the umbilical cord is yellow-brown (commonly known as the black umbilical).
2. Non-genetically modified soybeans (domestic soybeans, northeastern soybeans, Heilongjiang real estate soybeans): Round, full-grained, bright yellow in color, light yellow bean umbilicus.
Heat sink is a vital component that helps to dissipate heat from electronic devices. These devices generate heat as they operate, which can damage the internal components and cause malfunctions. In this article, we will explore what heat sinks are, how they work, and why they are important.
What is a heat sink?
A heat sink is a hardware device that is used to regulate the temperature of electronic components by dissipating heat. It is usually made out of an aluminum or copper plate with fins, which help to increase the surface area and improve the efficiency of heat transfer. Heat sinks are commonly used in electronic devices such as computers, power supplies, and mobile phones.
How do heat sinks work?
The purpose of a heat sink is to transfer heat from an electronic component to the surrounding environment. When electronic components such as CPUs or GPUs become hot, the heat is transferred to the metal plate of the heat sink. The heat sink then uses its fins to increase the surface area for the transfer of heat to the air. As the air flows over the fins, it absorbs the heat and carries it away, thus cooling the electronic component.
Why are heat sinks important?
Heat sinks play a significant role in ensuring that electronic devices function correctly and have an extended lifespan. Here are a few key reasons why heat sinks are important:
-
Improved performance: When electronic components become too hot, they can malfunction or slow down. Heat sinks help to regulate the temperature of these components, allowing them to operate at their full potential.
-
Extended lifespan: Overheating can cause damage to electronic components, leading to a shortened lifespan. Heat sinks help to prevent this by ensuring that the components are kept within their safe temperature range.
-
Reliability: By preventing excessive overheating, heat sinks contribute to the overall reliability of electronic devices, reducing the risk of malfunctions and failures.
In summary, heat sinks are an essential component of electronic devices that help to regulate the temperature of electronic components. They improve performance, extend the lifespan of devices, and contribute to their overall reliability. Regular maintenance, cleaning, and replacement of damaged heat sinks are crucial for ensuring the optimal functioning of electronic devices.
