Researchers have developed a transgenic rice strain which lowers blood pressure in laboratory rats. Genes from unrelated organisms were artificially introduced into the rice to cause production of ten different blood pressure affecting peptides.
In the future, taking your blood pressure medication could be as simple as eating a spoonful of rice. This "treatment" could also have fewer side effects than current blood pressure medicines. As a first step, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have made transgenic rice that contains several anti-hypertensive peptides. When given to hypertensive rats, the rice lowered their blood pressure.
The rice contains natural ACE inhibitors which help to regulate blood pressure and don't have the side effects often associated with pharmaceutical ACE inhibitors such as "dry cough, headache, skin rashes and kidney impairment."
Two hours after treatment, hypertensive rats showed a reduction in blood pressure, while rats treated with wild-type rice proteins did not. Treatment of rats over a 5-week period with flour from the transgenic rice also reduced blood pressure, and this effect remained 1 week later. The treated rats had no obvious side effects in terms of growth, development or blood biochemistry.
In the United States, Hypertension affects almost half of the adult population and is a primary or contributing cause of death for about half a million people per year.

This is also why there are typically lists that come with vaccines of whom it shouldn't be given to. If I were a few years older, I wouldn't have been able to receive the small pox vaccination due to skin problems and my brother had a reaction to the MMR vaccine and was only able to get two of the doses.
Turning food into medicine is one of those things that sounds like a good idea, until you realize that not everybody needs the medicine and that the effects may be bad for some segments of the population. And good luck ensuring that GMO traits don't transfer into neighboring crops, which would mean that there'd be no way of knowing, shy of genetic testing, what's actually in that food.
Really, there ought to be significant limitations on genetic engineering. Nothing beyond what could be done naturally via hybridization ought to be allowed. It's one thing if you're using genetic engineering to speed up a natural process and quite another if you're using it to take genes from an organism that can't even reproduce with the one you're targeting. Even just using it to speed up the process can be risky, food scientists have shown very little care or due diligence up to this point, so why would we expect them to start worrying about it?

"had a reaction to the MMR vaccine "
oh no he didn't! that was just a coincidence, blasphemer!
