Dr Marilyn Glenville PhD
The role of DNA testing in nutritional practice
Friday 3rd March 2017, 7 – 8.30pm
Talbot Hotel (formerly Stillorgan Park), Dublin
This talk will cover the science of nutrigenomics and how we can use genetic testing to personalise nutrition advice and physical activity recommendations tailored to the patient’s DNA. The results of genetic testing can impact weight management, cardiometabolic health, nutrient metabolism, food intolerance, eating habits, physical activity and injury risk.
There is increasing awareness among researchers, educators, healthcare professionals and consumers that the one-size-fits-all, population-based approach to nutritional guidance is inefficient and often ineffective. This awareness has created a growing market for personal, genetic testing advice. Recent advances in human genomics have uncovered extensive variations in genes affecting nutrient metabolism, but their full impact on nutrient requirements remains to be elucidated.
Differences in the rates of absorption, distribution, uptake, utilization, biotransformation and excretion influence the concentration of nutrients at a target site of interest, which ultimately impacts nutritional needs.
Research has shown that DNA-based dietary advice is superior to population-based recommendations at motivating changes in eating behaviors. Incorporating markers of genetic variation into studies of nutrition and health, aims to benefit those seeking personalised dietary advice by proving sound scientific evidence linking diet and health.
This presentation will explain the science of nutrigenomics and cover the most important markers in terms of nutrition and physical activity that impact on weight management, cardiometabolic health, nutrient metabolism, food intolerance, eating habits, physical activity and injury risk.
This talk is aimed at Nutritional Therapists and other health practitioners.
