Guest Bio

Nanci Guest, RD 
 nanci2

Nanci Guest is a registered sports dietitian and a certified strength and conditioning specialist (National Strength and Conditioning Association), and she has been working in private practice in this field for almost two decades.

Nanci completed an 18 month randomized control trial in late 2015 studying the effects of gene-nutrient interactions (nutrigenomics) on athletic performance at the University of Toronto as her PhD project, and she looks forward to publishing her results in 2016.

 

She attended the University of British Columbia and completed her Bachelor of Science degrees in agriculture and dietetics which also included several courses in kinesiology, and her Master of Science degree in nutritional sciences where she conducted research on eating behaviours and female athletes.

She has published her research in top journals, presented many abstracts at international meetings and given dozens of invited talks in Canada, the USA and Europe. Nanci is a global consultant to professional and amateur athletes and teams, in addition to having the role of head dietitian at both the Vancouver 2010 Olympics and the Toronto 2015 Pan Am games, and as a consultant to top Russian athletes in preparation for the Sochi 2014 Olympics. Many of the athletes she prepared for Sochi went on to win several gold and silver medals. She was also involved in creating formal nutrition guidelines for athletes for the International Olympic Committee.

 In this episode we discuss:

  • What exactly nutrigenomics is & distinction from nutrigenetics
  • Personalized nutrition: is it actually possible?
  • Genetic testing: what tests are validated? which are evidence-based?
  • What can we actually test for right now?
  • Interpretation of test results: are they actionable?
  • Personalized nutrition and dietary compliance
  • Nutrigenomics in elite sport to improve athletic performance
  • Why current research doesn’t match what some companies claim about sport genomics
  • Methodology of Nanci’s soon to be published RCT on caffeine, genetics and performance
