DNA profiling sounds reaks of ethical issues. The only good thing to obtain the right to patent is to prevent evil conglomerate from getting it first. Of course this would be naught if TPPA is a done deal.

That's the thing, why stop at dieting when you can extract the whole information like behavior, affinity or other phenotypes from the DNA. A single individual has the potential to generate thousands of dollars from their DNA data. This and times 1 billion middle class people, you can create a trillion dollar company.

Of course the DNA data can also be used to wipe an entire race of people in an extreme case. Imagine contaminating the water supply that only affect x race of people.
