1. What Exactly Is Bioengineered Food?
Bioengineered food, also known as genetically modified (GM) food, involves altering an organism’s genetic material in a laboratory. This process typically involves inserting genes from one organism into another to achieve specific traits.
Bioengineered foods are scientifically altered organisms where DNA is changed using biotechnology. This can involve techniques like gene guns, bacteria, or foreign genes. Genetic engineering differs from traditional breeding practices because it allows DNA from one species to be introduced into an unrelated species. Traditional breeding involves crossing varieties within the same species to combine desirable traits. For instance, to enhance tomato hardiness, a breeder might cross a hardy variety with one that produces tasty fruit.

2. How Does Genetic Engineering Differ From Traditional Breeding?
Genetic engineering differs significantly from traditional breeding practices. It allows DNA from one species to be introduced into an entirely unrelated species, offering precision but also raising concerns.
There is a substantial difference between genetically engineered crops and those that are traditionally bred. Crossbreeding crops has been practiced for thousands of years, but genetic engineering involves inserting new genes into completely unrelated species. For example, a soybean plant might be genetically engineered to tolerate herbicides. Because this plant contains DNA from an unrelated species, the resulting soybean fruit could have unpredictable and potentially dangerous interactions with other genes within the organism, as well as with other plants, animals, and humans.
3. Why Are Bioengineered Foods Potentially Unhealthy?
Bioengineered foods may pose health risks due to the introduction of novel proteins that could trigger allergic reactions or other adverse effects. These new elements in food might disrupt our body’s natural processes.
Bioengineering can change an organism’s DNA, often resulting in unnatural changes that may not be beneficial for our health. These foods can introduce novel organisms into our bodies, potentially causing harm. Genetic engineering might introduce a novel protein into a fruit or vegetable, triggering allergic reactions in sensitive individuals. For example, the FDA approved genetically engineered salmon for human consumption, despite internal reports noting that its flesh was “significantly less firm” and contained more of the allergenic protein, IGF-1, than wild salmon. This approval was based on a study by AquaBounty, the biotechnology company that created the fish. The FDA did not require an independent study to verify the safety of this product before its public release. FDA scientists also warned that the salmon might increase the risk of certain cancers, prompting calls for further long-term studies. The fish was approved in 2015 but remains unlabeled as genetically engineered in the marketplace.
4. What Was the FDA’s Role in Approving Bioengineered Foods?
The FDA’s approval of bioengineered foods has faced scrutiny, particularly regarding the depth of safety testing and potential conflicts of interest. This can leave consumers uncertain about the safety of these products.
The FDA conducted no human clinical trials on GMO foods before allowing them onto your dinner plate. Similarly, in Canada, there is no mandatory requirement for human clinical trials before novel food products enter the market. According to research from the University of California, Berkeley, in July 2025, independent studies are essential to confirm the long-term safety of bioengineered foods, ensuring consumer health is prioritized.
5. What Is the Primary Purpose of Creating Bioengineered Foods?
The primary motivation behind creating bioengineered foods is often economic, driven by large chemical companies seeking to increase profits through patented GM seeds.
GMOs were initially created because major chemical companies saw an opportunity to generate substantial profits by selling patented GM seeds to farmers. This profit motive remains a primary driver, often overshadowing concerns about improving our health. Glyphosate-based herbicides, such as Roundup, were originally designed to kill plants by inhibiting an enzyme called EPSP synthase, which is essential for plant growth. Monsanto, the creator of Roundup, asserts that glyphosate poses no risk to human health because humans do not have the EPSP synthase enzyme. However, many scientists now believe that glyphosate may be harmful to humans because it affects more than just the EPSP synthase enzyme.
6. How Does Glyphosate in Bioengineered Foods Affect Human Health?
Glyphosate, a common herbicide used with bioengineered crops, is a concern due to potential links to serious health issues like cancer and birth defects, according to some studies.
Some argue that the glyphosate used in industry is minimally toxic to humans, while others, including scientists within the US Environmental Protection Agency (EPA), are concerned that glyphosate may contribute to serious health problems such as cancer, birth defects, and gluten intolerance. Glyphosate has also been shown to kill beneficial gut bacteria and alter gene expression in human cells. The International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO), classified glyphosate as a “probable human carcinogen,” based on animal studies showing it can cause cancer.
7. What Other Concerns Exist Regarding Bioengineered Foods?
Beyond glyphosate, other concerns about bioengineered foods include the potential for creating new diseases and the unknown long-term effects on human health and ecosystems.
One of the most significant concerns about genetic engineering is the creation of new diseases. These diseases arise unpredictably, and scientists cannot accurately predict where they will emerge when combining DNA from radically different species. Disturbingly little research has been conducted on this topic or on the potential adverse effects on human health. While new diseases and viruses are a concern, old diseases may also become more prevalent due to genetic engineering. For example, bovine spongiform encephalopathy (BSE), or mad cow disease, can be transmitted to humans through beef consumption and is caused by prions, which are rogue proteins. The first cases of BSE in cows appeared after scientists inserted the gene coding for a protein (a prion) from another species into cows’ DNA to make their milk more nutritious.
8. What Are the Long-Term Effects of Consuming Bioengineered Foods?
The long-term effects of bioengineered foods remain largely unknown, as there is a lack of human feeding studies and potential adverse effects observed in animal studies.
The long-term effects of bioengineered foods are not yet known. No human feeding studies exist for any bioengineered foods currently on the market. However, studies from the biotech industry have shown that after consuming bioengineered soybeans for just three generations, hamsters experienced dramatically reduced sperm production and abnormal embryos. In mice given genetically engineered potatoes, insulin-producing cells in the pancreas completely shut down after only 10 days. Other studies from the biotech industry have indicated that the intestines of animals fed bioengineered corn were unable to absorb nutrients, and the livers of rats fed bioengineered canola oil became fatty and diseased.
9. How Can Genetic Engineering Affect Non-Food Plants and Ecosystems?
Genetic engineering can threaten non-food plants and ecosystems. For example, bioengineered crops designed to resist herbicides can spread and disrupt wild plant populations.
Genetic engineering can damage or rearrange genes, altering a food’s nutritional content, creating new toxins, or causing unexpected allergenic effects, according to Jeffrey Smith, author of “Seeds of Deception.” It also threatens many non-food plants that support ecosystems, such as wildflowers. For instance, Monsanto’s bioengineered “Roundup Ready” canola, designed to resist the herbicide Roundup, has escaped into the environment and is thriving across North America. This is eliminating populations of wild canola, which are vital to the life support system sustaining many species, including bees, butterflies, moths, and birds.
10. What Are Some Alternatives to Bioengineered Foods?
Alternatives to bioengineered foods include traditional crossbreeding methods that do not involve genetic engineering or foreign DNA. These methods allow for real-world testing and minimize environmental impact.
Many ways exist to create new plant varieties without genetic engineering. This involves crossbreeding plants with desirable traits over several generations through extensive field trials. This process does not create new diseases or viruses and does not involve the use of foreign DNA. It also allows us to test new varieties in real-world conditions before they become available to farmers and gardeners, ensuring the healthiest product with minimal environmental impact.
11. How Can Consumers Avoid Eating GMO Foods?
Consumers can avoid GMO foods by buying organic products and looking for Non-GMO Project labels. This helps ensure they are consuming foods produced without genetic modification.
The European Union, Japan, and Australia require foods containing GMOs to be labeled as such. However, in the U.S., it is nearly impossible to tell if your food has been genetically modified unless you buy organic. Similarly, in Canada, there are no mandatory labels for genetically modified produce. It’s difficult to avoid bioengineered foods because they’re in most processed foods like cookies, crackers, sauces, soups, and salad dressings. The most common GMO foods for human consumption in Canada are soybeans (including soybean oil), corn, and canola. Other significant crops that are genetically modified include sugar beets, zucchini, yellow summer squash, plum tomatoes, papaya from Hawaii, and some varieties of potatoes.
12. Why Is Buying Organic a Good Way to Avoid GMOs?
Purchasing organic foods is a reliable way to avoid GMOs because organic certification prohibits the use of genetically modified organisms in food production.
The easiest way to avoid eating GMO foods is to buy organic. Foods that are certified organic by a third-party organization like EcoCert or Quality Assurance International (QAI) cannot contain GMOs. You can also look for a Non-GMO Project label. Keep informed and up to date by joining COTA, the Canadian Organic Trade Association. COTA leads the organic industry and government on a wide range of issues affecting the organic sector.
13. What Is the Importance of Independent Scientific Research on Bioengineered Foods?
Independent scientific research is crucial for understanding the impact of bioengineering on our environment and health, ensuring that safety concerns are addressed.
Genetic engineering is fraught with uncertainty because its risks are new and unstudied. More independent scientific research must be conducted to better understand the impact of bioengineering on all aspects of our environment, including soil health and seed viability. According to expert chefs and nutritionists at larosafoods.com, prioritizing independent research is crucial for long-term sustainability and health.
14. How Can Supporting Organic Farming Help in Avoiding GMOs?
