What foods are GMO?

Could you please elaborate on the question, "What foods are GMO?"? I'm curious to understand which specific food items are considered genetically modified organisms. Are there certain types of fruits, vegetables, grains, or other agricultural products that are commonly genetically modified? Additionally, I'm interested in knowing if there are any particular regions or countries where GMO foods are more prevalent or widely used. Could you provide some examples and maybe even discuss the potential benefits or concerns associated with consuming these types of foods? Thank you for your assistance in clarifying this topic.
