A lot of people with gluten allergies can eat older strains of wheat that haven't changed since the early half of the century. The theory is that these are strains from before GMO time and were also not subjected to heavy selective breeding over the past century (of course it would have been selectively bred since the dawn of the fertile crescent 13,000 years or so ago).

From what I've read the people behind golden rice have yet to release their product for 20 years now, while at the same time in the US we've switched the majority of our largest crop yields to GMO products with wheat being the major holdout.

GMO corn, soybeans and sugar beets aren't being produced for health, they are being pushed to keep the American diet of highly processed sweets and oil cheap.
