Meet the dietitian
Rachel Ewing, RDN, LD
Warmest greetings!
Thank you for allowing me to share a bit about myself professionally and personally. I have served as a registered dietitian for 12 years, exploring the field of nutrition and dietetics throughout the Northwest. For the past four years, it has been a joy to work with patients at Heritage Health in Kellogg. In 2025, it was time to throw the net wider and open Silver Valley Dietetic Care to broaden the group of patients I am able to see in our community.
My family has the great honor of living in Kingston, Idaho! My husband, Ryan, and I have been members of the Silver Valley community for the past eight years and are long-time North Idahoans. We enjoy recreating all over these mountains, rivers, and lakes. I am a long distance runner, when I have the time, and enjoy road and trail racing. My personal time is poured into educating my three young children at home, connecting with my church family at Worship Center in Smelterville, and making memories with extended family throughout the Pacific Northwest.
What Is Nutrition and Dietetics?
Nutrition is the scientific study of how food affects the health of living organisms. It explores how the body processes nutrients through ingestion, digestion, absorption, transport, use, and elimination. Together, these processes make up metabolism.
Dietetics is defined as ‘the application of the science of nutrition to the human being in health and disease.’
What Is a Registered Dietitian?
A Registered Dietitian (RD), also referred to as a Registered Dietitian Nutritionist (RDN), is a licensed healthcare professional regarded as the field of nutrition’s experts.

They must also complete continuing education to maintain their credentials certified by the Commission on Dietetic Registration (CDR).
