A Whole New Era.
The completion of the Human Genome Project in 2003 heralded a whole new era in the practice of many aspects of medicine and healthcare.
Nutrigenomic tests using genomic data have been available for the last decade. Historically, these have been relatively expensive tests, yielding limited information for a practitioner using a functional medicine approach to healthcare.
More recently, however, it has become possible to have one’s full genome mapped at a much lower price, making it a test which is much more accessible to a much wider section of the population.
The Human Genome Is Vast.
The human genome is vast, containing about 3 billion base pairs which reside 23 chromosomes in the nucleus of our cells.
Hundreds to thousands of genes, which give instructions for making proteins in the body, are contained in these chromosomes.
It is therefore not surprising that the data provided by a full genome test can be exceedingly overwhelming, and that few practitioners feel comfortable using these tests.
Links To Effective Nutritional Health
There are many thousands of gene variants (single nucleotide polymorphisms or SNP’s) and, at this point in time, little is understood about the majority of them in terms of their functional roles, and their relationship and interaction with other genes.
There are, however, many genes that have been well researched over the last decade or so, and it is these that we should be focussing on. It is important to start with what we know already and work on exactly how we can incorporate this into an effective nutritional health programme for our clients.
