Could studying your DNA really help get your diet, fitness and beauty routine in check? Here’s what the science says.
There’s something quite vulnerable about sending off a swab of your DNA to the lab. The action feels like a scene from CSI: rubbing an elongated cotton bud on the inside of your mouth for 60 seconds, then sealing your sample in a plastic tube with your unique number stickered on the side. Is this really the lengths I’ll go to for better health and a more youthful complexion? Definitely! But first, let’s look at the science.
WHAT ARE YOUR GENES?
Quite simply, these are the segments that make up your DNA. “Your genes can be configured in thousands of different combinations which make up your genetic code,” explains Dr Daniel Meyersfeld of DNAlysis Biotechnology in Joburg. “Your code gives instructions to make the proteins you need. Variations in your code can change the way your body functions – that’s what we study.”
HOW DOES THIS HELP YOU?
“It’s clear that when it comes to diet regimens, fitness plans or medications, what works for one person doesn’t work for another,” explains Dr Meyersfeld. “With the studying of genes, we get a better understanding of why this happens. And, using that knowledge, we can now personalise a weight loss programme or a fitness routine just for you. Pre-empting any health issues can empower you.”
Be warned: not all genetic tests are made equal. While there are kits available online, it’s the analysis of the information by a professional, within the context of your likes, dislikes and lifestyle, that will make a difference. Googling your results can be overwhelming, not to mention confusing and possibly inaccurate.
