The popularity of DNA testing is widespread, but what, if anything can our DNA tell us about the food we should eat and the exercises we should do? Understanding nutrigenomics — the scientific study of the interaction of nutrition and genes, especially with regard to the prevention or treatment of disease — may provide some answers.

In this episode of the podcast, I am chatting with Courtney McCormick about nutrigenomics. Courtney is the Manager of Clinical Nutrition and Research for Tivity Health where she supports the overall clinical and nutrition strategies for the Nutrisystem and South Beach Diet brands. She is a registered dietitian with over 10 years of experience in nutrition and weight management. During our interview, we discuss:

• what nutrigenomics is
• a basic overview of where we were previously with genetic testing and where we are now
• what nutrigenomic testing is available to people in general
• the testing and report that Nutrisystem offered me via their DNA Body Blueprint
• how genetic markers work — do they absolutely predict traits or rather suggest tendencies
• steps someone would take if they were interested in the DNA Body Blueprint testing

I follow up my interview with Courtney by providing additional insight from registered dietitian Mary Purdy of Mary’s Nutrition Show on the importance of seeking out the support of a dietitian to interpret nutrigenomics results and provide recommendations on potential lifestyle and nutrition changes to be made.

Closing out the show via the Odds & Ends ending of the show I’m sharing my experience with ThredUp’s “goody box” that was discussed in The Online Clothing Consignment Episode. While the ordering and receiving process was seamless, the shipping/returns process was not and resulted in my account being charged for hundreds of dollars of clothing that I did not keep from the goody box. I share details of ThredUp eventually crediting me for that clothing, but summarize that for me this service isn’t worth the risk.
