What 5 foods are the most genetically modified?

Could you please provide a brief overview of the five most commonly genetically modified foods? I'm particularly interested in understanding which crops have undergone significant genetic modification and what are the primary reasons for their modification. Could you also elaborate on any potential health implications or benefits associated with consuming these genetically modified foods? Additionally, I'm curious to know if there are any regulatory measures in place to ensure the safety of these foods for human consumption. Thank you for your assistance in clarifying these points.
