Nutrigenomics : DNA Testing and Personalised Nutrition

Nutrigenomics is the study of how environmental factors such as diet and lifestyle affect the expression of our genes.

When we know our genetic tendencies we can tailor our diet and lifestyle to best support these tendencies.

Since the completion of The Human Genome Project in 2003 there have been major advances into the study of genes and their association with health and disease. New technology means that you can now obtain your own genetic data, and follow a specially designed nutritional plan that is specifically suited to your particular needs.

How can genetic profiling help?

Genetic testing can help identify small changes in our DNA code, which are known as Single Nucleotide Polymorphisms or SNPs for short (pronounced ‘snips’).

These SNPs can result in different tendencies for gene expression, which in turn can affect the production of enzymes, metabolic pathways and cellular function.

Some SNPs have been well researched and nutrition and lifestyle factors that influence their gene expression identified. A targeted nutrition plan, based on this information, can support your gene expression, and impact enzymes, metabolic pathways and cellular function all of which can have a huge impact on your overall health and symptoms.

Which test is best?

Genetic testing has recently become very popular and there are a number of different tests available so choosing the right test for you is key.

A reputable company will report on SNPs that have been well researched and where the impact of nutrition and / or environmental factors is well known.

Some tests focus on specific areas, for example methylation, oestrogen balance, detoxification or weight management and fitness, which may be useful if you want a targeted nutritional program to support a specific health concern. Others, such as 23andMe, provide you with the raw genetic data, which has to be run through an interpretation app or panel to provide any meaningful information.

Looking at the genetic profile in conjunction with careful case history assessment is crucial and it is important to remember that just because someone has a SNP or set of SNPs that this may not mean a gene is expressing and having any impact on your health.

Combining genetic testing with functional testing is ideal as it can give us more information about our current health and what impact any SNPs might be having on it.

It is also important not to focus on individual SNPs and make assumptions about disease risk.

How I can help

I have undergone specialist training and assessment in Nutrigenomics from a Functional Medicine Perspective and am registered with The British Association of Applied Nutrition and Nutritional Therapy (BANT) as a Nutrigenomic Counsellor. I regularly attend training events and seminars to keep abreast of the latest research.

I can offer interpretation of your DNA test results whether you already have 23andMe data, or would like me to suggest the best test or panels depending on your goals.

This information will then help you:

  • Optimise your diet and fitness training
  • Regulate your hormones
  • Improve your digestive health
  • Achieve your ideal weight
  • Support cardiovascular health
  • Address complex health concerns such as auto-immune conditions
  • Improve your overall health
  • Support healthy ageing and longevity
