About Heidi
What makes The
Healthy RD different?
As a registered dietitian of 25+ years, I've seen mainstream nutrition fail many patients — and myself. The more research I read, the more I know we need a deeper approach.
That's why I trained with The Institute of Functional Medicine. My blog and books help you get to the root cause of health issues and ask the right questions when you seek care.
Building blocks of nutrients and medicinal plants can be a simple — yet powerful — way to overcome even daunting health issues. When you're ready to go deeper, lab testing can help pinpoint exactly where to start.
