The buzz about DNA having an impact on losing weight or how our skin wrinkles may not be that far fetched. Really what it is all about, is how are bodies react to certain exposures that cause damage. Some people may fend off the damage caused by sun exposure really well but not so good at ridding the body of pollutants. Knowing your gene pool, or having the advantage to avoid certain habits and optimizing supplementation are just a few advantages to DNA testing.
Deoxyribonucleic acid-DNA is a very large molecule made up of smaller units called nucleotides that are strung together in a row. The nucleotide has three parts:sugar molecule, phosphate molecule, and structure called nitogenous base that carries genetic information. The nucleotides found in DNA come in four varieties:adenine (A), guanine (G), cytosine (C), thymine (T). These are the letters of the genetic alphabet. Current research determines about three million single nucleotide polymorphisms or SNP's. SNP's represent DNA sequences of small genetic variations. The SNP's have related enzymes that the body, when healthy, can activate to repair damaged DNA strands. This damage is caused by UV light, chemicals, and nuclear radiation. DNA damage at the cellular level are caused by certain processes such as methylation- the turning off and on of certain genes related to the heart, Inflammation, Glycation-blood sugar effects on protein and body fat, Oxidation-free radical damage, and DNA repair. When these processes are not optimal due to genetics DNA damage comes at a faster rate.
Testing by certain DNA laboratories can create customized medications, wellness products, and even diets that help protect against damage, prolonging aging, or at least allowing aging well. Genetic studies are just at the beginning of having impact on how we will take care of ourselves in the future.
