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 course in Translational Nutrigenomics is designed for the (licensed) health practitioner whose services integrate cutting edge nutritional science into client solutions. This is the only course in the world designed by experts in both Nutritional Biochemistry and Nutrigenomics.


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


The full course will cost $950 (USD). This does not include the nutrigenomics test required for the case study.


This global online course enables students to start at any time and in any time zone. Students will have 18 months to complete the course and can be done at their own pace.

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

Our Course


Capturing the Nutrigenomics Conversation. Our course consists of nine modules, these are detailed below.


Each module will include :

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

PART ONE: THE BASICS Genetics, Nutritional Biochemistry and Nutrigenomics

Chromosomal and molecular genetics, epigenetics, and an overview of nutrigenomics – Dr Yael Joffe

In this module we will explore chromosomal and molecular genetics, and the exciting area of epigenetics and how it interacts with nutrition. The last part of this module will be an overview of nutrigenomics, understanding about genetic variation and gene expression, and learning to differentiate between nutrigenetics and nutrigenomics.

Relevant nutritional biochemistry to understand key diet-gene interactions  – Dr Christine Houghton

This module takes complex biochemical concepts and simplifies them to the needs of the clinician. The first part of this module describes the biochemical story underpinning each of the genes we will be introducing in this course. In the second part, we will be addressing the various ways in which nutrients play an integral part in these biochemical pathways.

PART TWO: TRANSLATIONAL NUTRIGENOMICS™ Connecting Nutrigenomic Results to Clinical Practice

Nutrigenetics of Food Responsiveness – Dr Yael Joffe

Gene variations can be useful for understanding an individual’s response to a certain food or nutrient. This module explores gene variants that alter food responsiveness. Why one individual can drink coffee right up to bed-time and still sleep soundly comes back to our genes.

Interactive Pathways in Cellular Defences  – Inflammation and Detoxification associated genes – Dr Christine Houghton

Module 4 explores the biochemical processes underpinning the development of inflammatory diseases in general. Although diseases like asthma, psoriasis and osteoarthritis present very differently, they are all underpinned by the oxidative stress-inflammation couple. We will explore these and other gene variants that are associated with the inflammatory and detoxification processes.

Genetics of weight management and obesity – Dr Yael Joffe

This module explores the contribution of genetics to the susceptibility of becoming obese, but also why individuals respond differently to weight management interventions. You will also learn about the many factors that contribute to obesity such as sleep, behaviour, appetite and satiety, thermogenesis and exercise responsiveness.

Nutrigenomics and Nutrigenetics in Chronic Disease – Dr Christine Houghton

In this module (divided into 2 parts – 6a and 6b) you will understand why individuals with certain genotypes are predisposed to particular health abnormalities. Our focus is on cardiovascular disease, and type 2 diabetes as common diseases for which particular gene variants significantly impact cellular function. We will also review diet-gene interactions that impact processes that contribute the development of other chronic diseases.


Ethical issues and behavioural change in nutrigenomic testing – Dr Yael Joffe

As nutrigenetic testing becomes more affordable and available, it is important that equal attention is paid to the ethical, legal, and social aspects of nutrigenomics testing. In addition, you will understand how genetic tests differ and how this impacts the way you will interact with a client.

Supplement decision-making for the nutrigenomics clinician – Dr Christine Houghton

Our goal is to select an appropriate nutritional intervention to favourably modify the expression of a gene or compensate for the presence of a gene variant in a patient’s genomic profile. Such interventions may take the form of foods or supplements or a combination of these. This module introduces you to the process required to critically review a supplement formulation to determine its potential as an effective intervention.

Evaluating and using commercial genetic tests in practice – Dr Yael Joffe

In this module we will give you guidelines on how to evaluate commercial genetic tests, utilizing the principles of scientific and clinical utility. Furthermore, we will provide you with a set of criteria to evaluate individual gene variants for clinical usefulness. The second part of this module will introduce you to the idea of 3-3-3, this was developed to help practitioners manage the nutrigenetic results they receive back from the lab.

A comprehensive case study assignment at the end of course will provide the grade for the course. This will be based on the student’s nutrigenetic test results; evaluating genotype, and constructing dietary, lifestyle and supplement requirements. Students will be required to do their own (appropriate) nutrigenetic test if they haven’t already done one.

Our Instructors

Dr Yael Joffe and 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.
