Episode 11 – Nutrigenomics: Using Genetic Testing to Guide Personalised Whole Person Health
A conversation with: Dr. Denise Furness • Hosted by: Benjamin Brown
Listen now on:
Description:
Genetic testing can help guide highly individualised diet and lifestyle medicine-based interventions and is also highly motivational. We meet Dr Denise Furness, a pioneer and thought leader on nutrigenomics and hear how she started in research and extended into clinical work and education for health professionals focusing on the role of genomics in nutritional and lifestyle medicine. Our discussion includes foundational concepts around nutrigenomics in clinical practice and her recent BIO AGE study.
Guest:
Dr. Denise Furness, PhD

About our guest:
Dr. Denise Furness PhD is a pioneer in the field of nutrigenomics and personalised health with almost 20 years’ experience in the area. Dr Furness began her research career in 2003 investigating folate and B vitamin metabolism, methylation and DNA damage in relation to pregnancy health. Over the years her research expanded to include vitamin D, immune health and oxidative stress in relation to both male and female fertility. This research was conducted with the University of Adelaide, CSIRO human nutrition and The Women’s and Children’s Hospital in Adelaide, Australia. During this time, she witnessed a high success rate in the recurrent miscarriage and high-risk pregnancy clinics. She has published her work in peer reviewed journals and has won numerous awards for her research and conference presentations.
In 2012 Dr Furness founded Your Genes & Nutrition and began working with integrative medical doctors and learning about functional medicine. She has since become a prominent thought leader in this field and lectured for the Australasian College of Nutritional and Environmental Medicine (ACNEM), is editor of the ACNEM Journal and on the editorial board for the Nutritional Medicine Journal. Dr Furness regularly lectures globally at conferences for health professionals on topics related to nutrigenomics and functional medicine.
In her clinical practice, Dr Furness works with a range of patients helping them identify underlying triggers and root causes of their health concerns. Using a combined approach of genetics, biochemical markers, nutrition and lifestyle medicine she helps people take charge of their health and wellbeing.
