Functional Foods—the next wave of GE foods

"Functional foods", or "prescription" foods, as they have also been called, are the next big thing in biotechnology and genetically engineered foods. The purpose of functional foods would be to add ingredients that would in some way help tackle a health-related issue. So, you could have your favorite chocolate modified to contain some vitamins, or even a vaccine of some sort. I surely don't agree with the whole GE food thing, but I think the functional foods could potentially be a great idea. The one problem I see in doing all of this, however, would be how to get these edible vitamins or vaccines to the people who need them the most, and how would they afford them?
Interesting article to read.
