What are bioengineered foods?
Bioengineered foods are foods that have been created through the use of biotechnology. This means that they have been created by using living organisms or their components to modify the food.
Why are bioengineered foods controversial?
There are a few reasons why bioengineered foods are controversial. One reason is that there is not a lot of regulation around them. This means that companies can create these foods without having to follow strict safety

1.What are bioengineered foods?
Bioengineered foods are foods that have been created by using biotechnology. This means that the DNA of the food has been changed in a way that would not happen in nature.
One common example of a bio engineered food is corn that has been modified to be resistant to insects. This means that farmers can use less pesticides on their crops, which is better for the environment.
Another example is soybeans that have been modified to contain less saturated fat. This can help to reduce heart disease.
Generally, bioengineered foods are safe to eat. However, some people are concerned about eating foods that have been created in a laboratory.
There is also concern that bio engineering could be used to create “superbugs” – pests that are resistant to all pesticides. This could lead to more environmental damage and more use of harmful chemicals.

3.What are the benefits of bioengineering?
The list of potential benefits from bioengineering is long, and the technology has been slow to catch on in part because the food industry has been cautious about public reaction. But a few applications are already in wide use.
One of the most important is bioengineered crops that have been modified to be herbicide-resistant. These crops allow farmers to spray their fields with Roundup or other glyphosate-based herbicides without harming the crops. Glyphosate kills weeds but not plants that have the special gene added to them. As a result, farmers can use less labor to weed their fields, and they can spray their crops with herbicides earlier in the season, when weeds are small and easier to control.
Other benefits of bioengineering include:
-Disease-resistant crops. For example, papaya plants in Hawaii have been modified to be resistant to ringspot virus, which was decimating papaya production on the islands.
-Crops that can tolerate droughts or grow in saltier soils. For example, scientists are working on varieties of wheat, rice and corn that will be more productive in developing countries where water is scarce.
-Faster growing animals. Salmon that have been engineered to grow more quickly are already being raised in fish farms off the coast of Panama.
Whether these benefits will outweigh the potential risks associated with bioengineering remains to be seen. Scientists and food companies are continuing to study both the risks and benefits of bioengineered foods as we learn more about how these foods affect our health and our environment.
4.What are the risks of bioengineering?
When it comes to bioengineering, one of the main risks is that the genetic modification of plants and animals can have unintended consequences.
For example, when scientists insert a new gene into a plant or animal, they usually do not know exactly how that gene will be expressed. The gene might be expressed in ways that are different from what was intended – it might be more or less active than intended, or it might be active in unexpected tissues. This could lead to unforeseen changes in the plant or animal, some of which might be harmful.
There is also a risk that modified genes could spread to (and modify) non-target organisms through cross-pollination or other means. This could have negative consequences for the health of those organisms, as well as for the ecosystems they live in.
Some people also worry that we do not yet understand enough about genetics to create GMOs safely. They point out that our understanding of genetics has changed dramatically over the last few decades, and we are still learning new things all the time. As such, they believe it is too soon to start tinkering with the genes of plants and animals, as we may not fully understand the consequences of our actions.
5.What are the ethical concerns surrounding bioengineering?
Concerns about the ethical implications of bioengineering abound. One worry is that by tinkering with an organism’s genes, we are playing God. Another is that we may be interfering with the natural order of things, which could have unforeseen and potentially disastrous consequences.
Some people also worry that bioengineered foods will not be safe to eat. There is evidence, however, that bioengineering can actually make food safer by introducing new genes that make crops more resistant to pests and disease.
Another ethical concern is that bioengineering could be used to create “designer” babies—that is, babies whose genes have been selected for specific traits, such as intelligence or athletic ability. Some people argue that this would lead to a new form of eugenics, in which only the “best” genes are passed on and less-desirable genes are eliminated. Others contend that there is nothing wrong with using genetic engineering to improve the human species.
Finally, some people worry that corporations will patent bioengineered crops and animals, which would give them a monopoly on these organisms. This could lead to higher food prices and limit farmers’ choices about what to grow.
6.How are bioengineered foods regulated?
The FDA is responsible for ensuring that bioengineered foods are safe and labeled correctly. The agency uses a voluntary labeling system, meaning that manufacturers do not have to disclose whether or not their products contain bioengineered ingredients. However, if a manufacturer decides to label its products as “bioengineered” or “GMO,” the FDA must approve the label before it can be used.
There are two federal laws that govern the labeling of bioengineered foods: the Federal Food, Drug, and Cosmetic Act and the Fair Packaging and Labeling Act. The FDA has interpreted these laws to mean that manufacturers must disclose information about the presence of bioengineered ingredients if that information is “material” to consumers – that is, if it would affect their purchasing decisions.
The FDA has also issued guidance on how manufacturers can voluntarily label their products as “bioengineered” or “GMO.” This guidance includes recommendations on what type of information should be included on labels, such as a disclosure that the product contains bioengineered ingredients or a statement that the product is “made with genetically engineered ingredients.”
The USDA’s National Organic Program (NOP) also has regulations related to labeling of organic products, including those that contain bioengineered ingredients. Under the NOP, manufacturers cannot label their products as “organic” if they contain more than 0.9 percent genetically engineered ingredients. However, manufacturers can use the term “made with organic ingredients” on products that contain up to 30 percent genetically engineered ingredients, as long as they disclose this information on the label.
7.What are the labeling requirements for bioengineered foods?
Bioengineered foods are subject to the same labeling requirements as non-bioengineered foods. The U.S. Food and Drug Administration (FDA) requires that all food manufacturers accurately disclose the presence of bioengineered ingredients on the product label, regardless of whether the ingredients are from bioengineering or not.
The FDA also requires that any food that contains a bioengineered ingredient be disclosed on the label using one of the following terms: “bioengineered food,” “partially bioengineered food,” or “may contain bioengineering.”
The FDA does not require disclosure of information about small amounts of accidental or technically unavoidable presence of a bioengineered substance in a food. In addition, the FDA does not require disclosure of information about highly refined oils or sugars that may be made from crops that were originally bioengineered, because these ingredients do not contain any genetic material from the original plant and are therefore not considered to be bioengineered foods.
8.What are some common bioengineered foods?
There are many different types of bioengineered foods, but a few examples include:
-In 2018, 91% of corn planted in the United States was genetically engineered to be herbicide-tolerant. Maize is used in food for humans and animals, as well as in ethanol production.
-Soybeans were the first commercially cultivated genetically engineered food crop. In 2018, 94% of soybeans planted in the United States were herbicide-tolerant. Soybeans are used in products such as oils, tofu, soy milk, and meat substitutes.
-Cotton was the first genetically engineered plant to produce an insecticide (Bt toxin) in every cell of the plant. In 2018, 90% of cotton planted in the United States was genetically engineered for herbicide tolerance and/or insect resistance. Cotton is used to make fabric for clothing and other textiles.
-Canola was one of the first crops to be engineered to be tolerant to herbicides. In 2018, 88% of canola planted in the United States was genetically engineered for herbicide tolerance. Canola is used to make cooking oil and biodiesel fuel.
Other examples of bioengineered foods include papaya, alfalfa, potatoes, squash, apples, and salmon
9.How can I avoid eating bioengineered foods?
The Non-GMO Project offers a helpful Non-GMO Shopping Guide that you can download, or keep on your mobile device, to help you avoid purchasing foods that may contain GMOs. The guide includes both a list of brands that offer non-GMO products and a list of ingredients derived from GMOs that you should look out for when reading food labels. You can also download a PDF of the guide from their website.
The Environmental Working Group also has a helpful Shopper’s Guide to Avoiding GE Foods, which includes tips on how to avoid GMOs when shopping for food, as well as a list of brands that offer non-GMO products.
10.What is the future of bioengineering?
The future of bioengineering is shrouded in potential but fraught with controversy. Supporters point to the potentially life-saving advances in medicine and agriculture that could be made possible by manipulating the genes of living organisms. They also envision a future in which we can create custom-made organisms to perform specific tasks, such as cleaning up oil spills or producing biofuels. However, detractors worry about the unintended consequences of releasing genetically modified organisms into the environment and the ethical implications of tinkering with the building blocks of life. As the debate continues, researchers are making progress on a number of fronts, from developing crops that can withstand droughts and pests to engineering bacteria that break down plastics. Only time will tell what role genetically modified organisms will ultimately play in our world.
