Skip to 0 minutes and 4 secondsMELISSA ADAMSKI: So while this area of science is not something that has been implemented mainstream in the medical and nutrition professions at this stage, it is an area that I encourage all health care professionals to do more reading on and make sure that you're on top of the evidence. Firstly, the media are very interested in this new so-called DNA diet. How our genetics can affect our nutrition requirements, it's starting to come through in some of our public health guidelines. For an example here in Australia in 2012, the Medical Journal of Australia released their position statement on vitamin D for Australians and New Zealanders.

Skip to 0 minutes and 40 secondsAnd within that position statement, there is a section on how our genetics does influence the vitamin D status of our bodies. Now while this position statement does suggest that these genetic variations do play a role in our levels of vitamin D, the position statement does not provide us with any advice on what we should actually do with that should a patient ask us how they should change their vitamin D intake. Or what we can actually do about it if a patient actually does show that they have one of these polymorphisms. Another area you may come across nutritional genomics in your practise is the area of genetic testing.

Skip to 1 minute and 16 secondsTraditionally, genetic tests were offered through medical specialists who were trained in the specifics of genetics. However, now, patients and individuals have access to a wide range of genetic tests through many different avenues, including health care professionals who may not have been traditionally involved in genetic testing in the past and also online through biotechnology companies. We need to be able to critically analyse these test results and have an understanding if there is any usable information from this that we were able to apply to our recommendations for the patient. Another area of nutritional genomics that you may come across in your practice is the area of supplements.

Skip to 1 minute and 57 secondsAnd we are now seeing a wide range of supplements coming on the market that are targeting themselves or claiming that they're able to support our DNA health. And it's very important, as a health care practitioner, we're able to critically analyse these supplements and understand whether they have any benefit for our patients or not. So as you can see, there are many areas of nutritional genomics that may touch your practise, even if you're someone who's thinking that it's not something that you'd like to implement at this stage. Questions that I'd like to leave you with are what are the best practice guidelines in your health care profession?

Skip to 2 minutes and 31 secondsAre there any guidelines from your professional bodies in how to implement this into your practice? Whether it's something you use in practise or not, it's very important that you stay on top of the science, on top of the evidence, so you can competently discuss this with your patients when they have questions for you.
