The online Foundations in Nutrigenomics course
is now open to all health professionals, anywhere in the world.

Nutrigenomics is the cutting edge of nutrition science. As interest in personalized medicine increases, your patients will ask you about genetic testing. This course will provide practitioners with adequate training to accurately and usefully interpret their client’s results and transition them into realistic and personalised food solutions.





This Nutrigenomics course is designed for health practitioners whose services integrate cutting edge nutritional science into client solutions. It is also ideal for those with a degree in nutrition science or food science. If you are unsure, please contact us.


This online course will provide practitioners with a review of relevant nutritional biochemistry and current nutrigenetic science. In addition, a part of the course will be dedicated to the use of commercial tests in practice, and interpretation of nutrigenetic information for patients.


The cost of the Foundations in Nutrigenomics course is $595 (USD).


Students may start at any time and in any time zone. The Foundations course will take between two to three weeks full-time, and two to three months part time. The course should be completed in span of 6 months.

Students will require access to a computer and adequate Internet capability.

Foundations Course


Our course consists of four modules, these are detailed below.


Each module will include :

Recommended readings and resources | Videos | Powerpoint based lecture | Online quiz

Introduction to Genetics – Dr Yael Joffe

An Introduction to Genetics will define and illustrate (with practical examples) the difference between nutrigenetics, nutrigenomics and epigenetics. In this module we will also explore the concept of food responsiveness, including examples to illustrate how they can be used in clinical practice, looking at gene-nutrient interactions for iron, lactose, salt and gluten, caffeine, and fatty acids.

Integration of Cellular Defence Mechanisms into Nutrigenomics  – Dr Christine Houghton

This Integration of Cellular Defence Mechanisms module provides a brief summary of cellular defence mechanisms, including: redox status, inflammation, energy production, methylation, and detoxification. For each area the relevant genes, SNPs and diet-gene interactions are described. The module also briefly reviews genes and SNPs that impact insulin resistance, the endothelium, and lipid metabolism, and their relationship to chronic disease.

The Genetics of Weight Management and Obesity – Dr Yael Joffe

Module three will explore Weight Management. Understanding the contribution of genetics to the susceptibility of becoming obese, and why individuals respond differently to weight management interventions. It will identify the many factors that contribute to obesity such as sleep, behaviour, appetite and satiety, thermogenesis and exercise responsiveness, and the diet-gene interactions that will impact these processes.

Clinical Implementation – Dr Yael Joffe

Module four addresses Clinical Implementation. Understanding the importance of the ethical, legal, and social aspects of Nutrigenetic testing. Students will be provided with criteria to evaluate individual gene variants for clinical usefulness. The second part of this module will teach the clinical implementation tools of the 6-Step Approach and 3-3-3. In addition to the theory, 3-3-3 case studies will be used to enable practitioners to become familiar with using this tool in their practice. Additional case study snap shots are also provided.


At the end of each module in the Foundations course you are required to complete a 10 question multiple choice quiz before you can proceed to the next module. Once you have completed the Module 4 quiz with 100%, you would have completed the course. We do recommend that students do their own (appropriate) nutrigenetic test if they haven’t already done one. But it is not a requirement.

Our Instructors

Dr Yael Joffe and Dr Christine Houghton have expertise and experience in Human Genetics, Molecular Biology, Nutritional Genomics, Dietetics, Functional Nutrition, Nutritional Biochemistry, Food Systems, and Culinary. Together they have over 40 years experience in all aspects of Nutrigenomics, especially the implementation of Nutrigenomics into clinical practice. They have significant experience in teaching Nutrigenomics and nutrition at a post-graduate level, present regularly at Nutrigenomic and nutrition conferences, and are published authors. All course content will be evidence-based and fully referenced.
