That branch of biology specialising in genetics is a very diverse and interesting one, giving rise to many different careers. Some of these careers have been around for longer than anyone reading this content has lived, like forensics, DNA testing for paternity determination, biometrics, etc.
One of the newer sub-fields to have recently emerged within the broader field of genetics is that of DNA testing. It’s a special, targeted type of DNA testing, because you would be right if you pointed to DNA testing having been around for as long as there has been an interest in its study.
The underlying reasons for the emergence, existence and development of this targeted variety of DNA testing may appear to be a little bit more politically motivated, because what good does it do for one to be able to trace their ancestry to two different countries in two different continents, for instance? How does that information help you, other than perhaps with something like an inheritance that might be due to you, your eligibility to be admitted to a certain country you might want to permanently relocate, etc?
Either way, those underlying motives give rise to an application that appears to be a lot more positive, which is of course the service of creating nutritional and even workout plans based on the results of a DNA test you would undergo. It’s an increasingly popular practice and subsequent service in regions of the world where there is a national and regional agenda for their population to compete to win at the international stage, in many areas of competition, like sports, the space race, etc.
Do the DNA-tailored plans actually work though?
As with questions such as “how long is a piece of string?,” to which the answer depends on the context and number of other factors, the answer to the question of whether DNA-tailored nutritional and fitness plans work depends on a sizeable set of contextual circumstances. The immediate indication is that it does, but that’s just based on the current, collective knowledgebase we possess about health and nutrition.
Nobody has all the answers, neither does everybody collectively. For those segments of the health and fitness industry which we’ve long since figured out and are fully confident of the accurate knowledge of, the answer is a resounding YES! If you are genetically predisposed to developing prostate cancer, for example, that could be picked up in the DNA testing part of this DNA-tailored nutritional planning service. You would then benefit from incorporate natural cancer-cell killing nutrients in your diet.
For someone whose DNA test reveals interesting derivative findings such as an above-average lung capacity, to make another example, the answer to questions such as how long should you wait between vapes would be different. More importantly though, this would demonstrate the advanced application of DNA-tailored lifestyle plans around health and nutrition, because what becomes apparent are some justifiable predications like how this person with a greater lung capacity has a higher possibility to succeed at kicking their smoking habit.
