What are genetically modified foods?
Genetically modified foods, or GM foods, are also known as genetically engineered foods, or bioengineered foods. They are foods produced from organisms that have had changes introduced into their DNA using various methods of genetic engineering. These methods allow scientists to create new traits in plants, animals, or microorganisms that do not occur naturally, such as resistance to pests, diseases, herbicides, or environmental stress, or enhanced nutritional value, flavor, or shelf life.

Why are GM foods produced?
The main reasons for producing GM foods are to improve crop yield and quality, reduce agricultural inputs and costs, and address food security and environmental challenges. For example, GM crops can help farmers cope with pests and weeds that reduce their harvests, or grow in harsh conditions such as drought or salinity. GM foods can also provide consumers with more choices and benefits, such as rice enriched with vitamin A to prevent blindness in children, or soybeans with healthier oils that do not contain harmful trans fats.
How are GM foods regulated and assessed for safety?
Before GM foods can be marketed and consumed, they have to undergo rigorous safety assessments by national authorities and international organizations. These assessments evaluate the potential risks and benefits of GM foods for human health and the environment, based on scientific evidence and international standards. The safety of GM foods is assessed differently from conventional foods, because they may have novel characteristics that require additional testing and evaluation. Some of the aspects that are considered in the safety assessment of GM foods include:
The source and nature of the genetic modification
The molecular and biochemical characteristics of the GM food
The nutritional composition and allergenicity of the GM food
The potential toxicity and unintended effects of the GM food
The potential environmental impact of the GM food
According to the World Health Organization (WHO), the Food and Agriculture Organization (FAO), and other leading health organizations, GM foods that have been approved for commercial use have passed safety assessments and are not likely to present risks for human health. However, they also acknowledge that each GM food has to be evaluated on a case-by-case basis, and that continuous monitoring and research are needed to address any emerging issues or uncertainties.
What are the main issues of concern for human health and the environment?
Despite the scientific consensus on the safety of approved GM foods, some people have expressed concerns about their potential adverse effects on human health and the environment. Some of the main issues of concern include:
The possibility of introducing new allergens or toxins into the food supply
The potential for gene transfer from GM foods to human cells or bacteria in the gut
The potential for antibiotic resistance genes used in genetic engineering to spread to pathogenic bacteria
The impact of GM crops on biodiversity and ecosystems
The emergence of pest or weed resistance to GM traits or herbicides
The ethical and social implications of manipulating living organisms
The economic and political influence of biotechnology companies on agriculture and food systems
These issues have been debated by various stakeholders, such as scientists, regulators, farmers, consumers, activists, industry representatives, and policy makers. While some people support the development and use of GM foods as a way to enhance food production and quality, others oppose them as a threat to human health and the environment. The public perception and acceptance of GM foods vary depending on the level of awareness, education, culture, religion, and values of different regions and countries.
How can I tell if my food contains GMOs?
In some countries, such as those in the European Union (EU), Japan, Australia, New Zealand, China, India, Brazil, South Africa, and others, there are laws that require labeling of GM foods or ingredients that contain more than a certain percentage of GMOs. These labels inform consumers about the presence or absence of GMOs in their food products, and allow them to make informed choices. However, in other countries, such as the United States (US), Canada, Argentina, Mexico, Chile, and others, there are no mandatory labeling requirements for GM foods or ingredients. In these countries, consumers may rely on voluntary labels, such as "Non-GMO Project Verified" or "USDA Organic", to identify non-GM foods or ingredients. Alternatively, consumers may use online databases, mobile apps, or barcode scanners to check the GMO status of their food products.
