1. If you’ve ever eaten a piece of fruit, a vegetable, or a packaged food made with corn or soy, it’s likely that you’ve eaten a genetically modified organism (GMO). These are foods that have been changed in a laboratory to have specific traits, like being pest-resistant or being able to grow in certain conditions. 2. Though GMOs have been around for a few decades, people are sometimes concerned about whether or not they’re safe to eat. So far, studies don’t show any health risks associated with eating genetically modified foods, but there are still unknowns and concerns about their safety. Here, we’ll review what GMOs are used for, some common concerns about them, and what the research says so far. 3. What are GMOs? GMOs are living beings that have had their DNA (genetic material) changed. This is done in a lab through a process called genetic engineering. With this process, scientists can move desirable genes from one plant, animal, or microorganism...
