Genetically Modified Food: A Controversial Topic
The safety of genetically modified (GM) food remains one of the most debated topics globally. According to the latest global report on GM crops, 59 countries or regions have approved over 2,000 applications for genetically modified crops, with food items making up nearly half of these applications—far exceeding those for feed and other uses. This indicates that GM foods are increasingly becoming a part of our daily lives.
Despite the rapid adoption of GM technology, public concerns about its safety continue to grow. Dr. Clive James once described GM technology as "the fastest adopted cultivation technology in modern history," highlighting how quickly it has been embraced by farmers and scientists worldwide. In the most recent annual report, he noted that 59 countries have approved 2,497 GM applications involving 319 different plant varieties across 25 crops. Of these, 1,129 were for food, 813 for feed, and 555 for planting. This shows that GM food projects dominate the field.
Transgenic technology involves using modern molecular techniques to transfer genes from one organism to another, altering traits such as nutritional value, quality, and resistance to pests and diseases. Genetically modified foods are those that are directly consumed or used as raw materials in food production.
In the early 1990s, the first genetically modified food—a genetically modified tomato—was introduced in the United States. Although it was initially developed in the UK, it was commercialized in the U.S., marking the beginning of widespread GM food use. Since then, the U.S. market has seen an explosion of GM products, with over 60% of processed foods containing GM components, and more than 90% of soybeans and 50% of corn being genetically modified.
In the U.S., GM foods include not only transgenic plants like tomatoes, potatoes, and corn but also genetically modified animals such as fish, cattle, and sheep. These organisms often exhibit enhanced traits like pest resistance, disease resistance, and improved yield, even if they taste similar to conventional counterparts.
China also entered the GM food market with the introduction of genetically modified tomatoes and sweet peppers. Additionally, China imports GM corn, soybeans, and rapeseed from the U.S., primarily for animal feed and oil production.
As GM rice cultivation became a topic of concern in China, the U.S. approved six transgenic rice varieties, while Iran and other countries also allowed GM rice for consumption. This highlights the global spread of GM technology and the ongoing debate surrounding it.
Despite growing acceptance, the safety of genetically modified foods remains a subject of controversy. While some experts argue that there is no scientific evidence linking GM foods to health risks, others express concerns about long-term effects. Studies suggest that GM foods undergo rigorous testing before reaching the market, including long-term health assessments that go beyond typical consumption levels.
Environmental groups also raise concerns about the potential impact of GM organisms on ecosystems. However, many scientists emphasize that genetic modification does not pose a unique risk compared to traditional breeding methods. In fact, the human body breaks down food into smaller molecules during digestion, making it unlikely for foreign genes to affect human genetics.
To address public concerns, strict regulatory frameworks are essential. Scientists and policymakers must work together to ensure transparency, safety, and public trust in genetically modified foods. As the world continues to embrace biotechnology, it's crucial to balance innovation with caution and responsibility.
