Are DNA tests useful in personalized lifestyle holidays?
Recently the New York Times reported that the FDA got involved in “regulating consumer genetics”. This might be useful to ensure the value of DNA tests in a positive outcome.
It is on this last point that I hope to enlighten readers. In this case, a positive outcome implies that the client is able to minimise his health risks by aligning his lifestyle as closely as possible to his DNA risk profile.
The problem with consumer genetics (buying your test over the counter / internet) is thus that you have the information, but might not apply it, and thus have no guarantees that it will ensure any lasting lifestyle change.
