Are Our Genes Still Evolving?

Of course we are still evolving, it would be very egocentric to believe that we have reached an apex. I would definitely question though, how genetically modified foods and those fed to the animals that most people consume alter us genetically. Also, that a gene may be modified so that it can be patented and it's life cycle destroyed, and what effects this food has on us cellularly. Could these new practices discourage our genes from evolving? Or maybe, genetically, we will evolve so that we can adapt to this transformation, but then what is this doing to the natural process of evolution? I believe that we are tinkering in very dangerous and unknown terrain and continuing to do so may alter genetic codes in an irreversible and devastating rate.
