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.

Potential risks to human health

There are potential risks to human health associated with consuming GMOs. Some people have safety concerns related to the consumption of GMOs, as there is limited research on the long-term effects of consuming genetically modified foods. Additionally, there is a possibility of allergenicity or toxicity of GMOs, which could pose risks to certain individuals.

While some studies have suggested that GMOs are safe for human consumption, there is still a need for more long-term studies on the health effects of GMOs to fully understand their potential risks and benefits. It is important to continue to monitor and evaluate the safety of GMOs and to take appropriate measures to minimize any potential negative impacts on human health.

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).

Here’s the bottom line

GMOs are foods that have been modified using genetic techniques. While most foods in your local supermarket contain GMO ingredients, plant-based protein offers a healthier and more sustainable alternative to animal-based protein.

In the United States, foods grown using GMO techniques include corn, soybean, canola, sugar beet, alfalfa, cotton, potatoes, papaya, pink pineapple, summer squash, and a few varieties of apples. Although current research suggests that GMO foods are safe for consumption, some people are concerned about their potential health effects. Due to a lack of long-term human studies, more research is needed to fully understand the impact of GMOs on human health (source 1).

As of 2022, all foods in the United States that contain GMO ingredients must have the term “bioengineered food” somewhere on the packaging or a scannable code to show that it has GMO ingredients (source 2). With the growing popularity of plant-based protein, consumers have a choice to opt for healthier and more sustainable protein sources that are free from GMOs and other harmful additives.
