Introduction to GMOs
GMOs, or genetically modified organisms, have been at the center of much debate and controversy. According to the U.S. Department of Agriculture (USDA), GMO seeds are used to plant over 90% of all maize (corn), cotton, and soy grown in the United States, meaning that GMOs are likely present in many of the foods we consume
What are GMOs?
Genetically modified organisms, or GMOs, are organisms whose DNA has been altered using genetic engineering technology. In the food industry, GMO crops have had genes added to them to improve their growth, nutritional content, sustainability, pest resistance, and ease of farming. While it’s possible to naturally give foods desirable traits through selective breeding, this process takes many generations and may be difficult to control. Genetic modification significantly accelerates this process by using scientific techniques to give the plant a specific desired trait.
One of the most common GMO crops is Bt corn, which is genetically modified to produce the insecticide Bt toxin, allowing it to resist pests and reducing the need for pesticides. At least 90% of soy, cotton, and corn grown in the United States are genetically modified (4Trusted Source).
The Debate Over GMOs continues as GMO crops make farming easier. However, there is some concern around their potential effects on the environment and their safety for human consumption, specifically regarding illnesses and allergies. Despite this, the Food and Drug Administration (FDA), Environmental Protection Agency (EPA), and USDA maintain that GMOs are safe for human and animal consumption.
Understanding the Pros and Cons of GMOs
Although many prominent organizations and research studies suggest that GMO foods are safe and sustainable, others have raised concerns about potential harm to human health and the environment. This article aims to provide a balanced explanation of the pros and cons of GMOs, as well as guidance on how to identify GMO foods. By understanding the potential risks and benefits of GMOs, consumers can make informed decisions about the foods they choose to eat.

How do you identify GMO foods
Identifying GMO foods can be challenging, as most foods in supermarkets are made with ingredients from GMO crops. While GMO foods appear safe for consumption, some people wish to avoid them.
GMO crops grown and sold in the United States include corn, soybean, canola, sugar beet, alfalfa, cotton, potatoes, papaya, pink pineapple, summer squash, and a few apple varieties (source 1).
In the United States, no regulations currently mandate the labeling of GMO foods. However, as of January 2022, the USDA requires food manufacturers to label all foods containing GMO ingredients as “bioengineered food” using either the USDA bioengineered food symbol, listed on or near the ingredients, or a scannable code on the package with directions (source 2).
Presently, some foods may have a third-party “Non-GMO project verified” label, indicating that the product contains no GMOs, but this label is voluntary (source 3).
Foods labeled “100% organic” do not contain any GMO ingredients, as U.S. law prohibits this. However, products labeled simply “organic” may contain some GMOs (source 4).
In the European Union, foods with more than 0.9% GMO ingredients must list “genetically modified” or “produced from genetically modified [name of food]” on the packaging or near the item (source 5).
