I've heard a lot of talk about the dangers of GMO foods. Should I be concerned?

It depends on what you mean by “GMO” and how much you know about it. Generally speaking, genetic engineering is a technique used to insert new genes into an organism’s genome. In some cases, this involves taking genes from one species and inserting them into another. This can be done in order to create crops that are resistant to pests or diseases, or that have higher yields, for example.
