Epigenetics and Nutrigenomics

The science of nutrigenomics studies the interaction between dietary components of food and our genes. Every individual has a unique genetic profile, and through our understanding of nutrigenomics we now understand that promoting good health through food, will be different for each person.

​With the completion of the human genome project and the latest nutritional science, it’s clear that nutrigenomics is no longer the future of medicine. It’s here today. And it’s being applied by cutting-edge health experts worldwide everyday.

There are two ways we can use the information from a genetic test to improve health.

First, we look at common variations found throughout the human genome to explain why some individuals respond differently than others to the same nutrients. For example, why some people can eat a higher fat diet with no adverse consequences and others cannot. 

The second approach that nutrigenomics researchers use is to investigate how nutrients and components in food turn genes on or off.  Whole Body Health Genetic Testing focuses on the genes that we know impact important metabolic pathways in the body. Once you have the genetic testing information, these compromised pathways are identified. The final and most beneficial step being the dietary and lifestyle information on how to switch on or off the gene expression as necessary.

This is the science of epigenetics – the understanding that gene expression can be changed through diet and lifestyle.

The key to making the testing useful is in the interpretation of the results. Once we know the pathways that have the potential to initiate disease, the logical next step is to implement changes to the diet and lifestyle in order to mitigate these. This is where a Naturopath comes in, to prioritize, and to help you understand the often quite simple changes you need to make to stay well.

Genomic testing is a science, and there are many tests available on the market.  Some provide very useful information, and many others do not.  Genetic testing is a once only test, and you want to  know that you are getting the information you need to get well or stay well. 

In order to get the full benefit of the testing you need to ensure:

• You use a certified lab with quality control measures in place
• The testing only reports on the genes that have research to back their impact on health (the rest is just fluff that is confusing                    and gets in the way of what is important)
• You have a healthcare professional to interpret the results for you.
