Genetic testing offers an extensive array of new opportunities in evaluating health outcomes and as a result, it has captivated the sciencitic community. This leaves us questioning if we should do genetic testing and how it can benefit us.
Your DNA (or genes) is the foundational blueprint of who you are. Your DNA codes for your hair colour, your height, and even the shape of your ears. DNA codes for what you can physically see as well as what you can not see. Your DNA will also determine how your body processes certain nutrients, how it makes hormones as well as how several metabolic processes are happening in your body.
Genetic reports are able to give unique personalised information on the best way for a specific individual to lose weight, maintain good health and decrease the risk of certain disease conditions. Genetic tests can supply a vast amount of information. The following are examples of what genetic tests could indicate:
You can’t change what DNA you have but you can change how it functions. Think of it like this. Your genes loads the gun but your lifestyle pulls the trigger. Testing your genetics is helpful as you can determine where you have ‘loaded guns’ or points of concern. A loaded gun is potentially dangerous but it is only deadly when you pull the trigger. Lifestyle choices pulls that trigger. If you improve your diet and lifestyle, you will prevent a ‘gun from triggering’ and decrease risks for disease.
Genetic testing provides a unique insight on health,diet and physical activity optimization. This does not mean that other interventions are no longer needed, it merely means that it is now more personalised. There is more individualised information to help you be the best health version of yourself.
