We are now entering an age where you can take your nutrition one step further and personalise it to your own genetics.  Ever heard of Nutrigenomics?


It sounds like some kind of futuristic movie concept, but it is real and defined as the study of the interaction between nutrition and genes.

Why do people experience different health outcomes even though they eat pretty much the same diets and practice similar lifestyles? This is an important question that has long plagued nutrition and other healthcare experts.

It’s thought that genetics affect how a person responds to dietary intake. Only recently, research in the field of nutrigenetics has shown this. This is especially relevant to the prevention and treatment of disease.

Did you know most people are approximately 99% genetically identical? This 1% genetic variation leads to differences of health outcomes, depending on dietary intake and other environmental factors.


A common example is when you compare two men of the same age both have a diet low in fruits and vegetables and high in salt and unhealthy fats. One develops high blood pressure and high cholesterol which leads to heart problems, while the other lives a long life disease free.


This genetic variability affects a person’s nutritional status in many ways. A person’s genetic sequence affects his or her nutrient requirements, energy utilisation, appetite and taste, as well as risk of chronic disease in response to diet.

When talking about chronic illnesses, like heart disease, diabetes and cancer, they are nearly bordering on an epidemic as they have skyrocketed over the last 100 years. It has been linked it to lifestyle and environmental factors as our genes as they haven’t changed much over that time.

Our genes don’t necessarily control our destiny when it comes to health, what has been a topic for research is if diet and lifestyle can actually change our genetic outcome. The answer is yes and what a powerful tool to use in prevention of disease rather than focusing on treatment. Empowering us with the knowledge to follow a diet that can be lead to longevity and improve our quality of life.

From personal experience with clients, it is clear that everyone reacts differently to healthy dietary changes. I am excited to have done an intensive course with DNAlysis, which makes me a certified practitioner who will be able to send client’s DNA to be tested. What an exciting step forward in giving us in the nutrition field a sure way of making recommendations that are even more individualised. It is as simple as brushing the inside of your cheeks with an earbud and sending it off to the lab. Results usually take between 2-3 weeks, with an extensive report.

There are different sets of genes that can be tested It is important to take note that we are not helpless in affecting the outcome of these genes that are tested. You will be able to make a change to the outcome of how they are expressed. You can do this through specific lifestyle and environmental changes.

DNAlysis offers four sets of tests:

  • DNA Diet
  • DNA Health
  • DNA Sport
  • DNA Oestrogen


The DNA diet test:

The test looks you DNA and if there are any genetic mutations that can influence your ability to lose weight. According to the results of your test, your DNA can help in determining whether you will get the best weight loss results on one of the following three diets:

–       Low Carbohydrate

–       Low Fat

–       Mediterranean

The DNAdiet also provides you with recommendations for type of exercise, intensity and duration in your report to get you on track.


The DNA Diet is for you if:

– You have tried various types of diets and are doing everything right, but not seeing the results you want

– You are wanting to lose weight

– You want to maximise your exercise type and intesnsity to get you the best results
