Nutrition and Genetics: from fundamentals to application in personalised nutrition

The growth of personalised healthcare, based on a person’s unique genetic code, is just one of the outcomes from research into genetics and the human genome. Today, a quick search on the internet returns dozens of ‘at-home’ genetic test kits, promising to reveal anything from food sensitivity to cancer risk. However, there is a worrying lack of regulation surrounding these kits, with commercial considerations further muddying the waters.

Given the trend towards personalisation, it’s crucial that nutritionists and dietitians continue to provide safe, science-based advice to their patients and clients that encompasses this growing trend and ‘at-home’ genetic testing kits.

The St Mary’s University Nutrition and Genetics research group has developed a short course designed to support nutritionists, dietitians and all learners navigate this complex subject area.

Association for Nutrition Endorsed CPD

AfN endorsed CPD logo (Endorsement No: EN231)This course has been endorsed by the Association for Nutrition (AfN) for the continuing professional development of nutrition professionals. The AfN quality assurance mark identifies this activity as reputable, evidence-based training in nutrition science.

Association for Nutrition CPD Endorsement runs from 20th November 2020 to 19th November 2022.


By the end of this course, learners should be able to:

  • understand and define key terms in nutrition and genetics (nutrigenomics vs. nutrigenetics vs. epigenetics vs. personalised nutrition)
  • provide examples of gene-diet interactions and understand the basics of evaluating the scientific validity of such interactions
  • apply this theory and provide personalised dietary recommendations in different mock scenarios
  • understand and evaluate the differences between “good” and “bad” direct to consumer company reports and ethical issues associated with providing genotype-based dietary advice.

Learners will also get a pocket-sized reference guide.

"This workshop will benefit the public, by upskilling registrants in the evaluation of nutrition and genetics, supporting the debunking of misinformation that currently is prevalent in this area."Association for Nutrition independent assessor comments
