Christelle Smith

BSc Dietetics cum laude (NWU) 2014

I believe in a no-nonsense and evidence-based approach to nutrition.

Translating nutrition science into a more practical and understandable language for my clients brings me so much joy. This helps to empower them in order to make lasting lifestyle and dietary changes.

Living in China and traveling for three years also gave me a more open-minded approach.

I joined the Waterfall Nutrition team in 2021 and I am mainly seeing in-hospital patients but do see clients at our practice as well.

My special interests are:

Critical care, renal nutrition, diseases of lifestyle (Diabetes, High Blood Pressure/Hypertension/High Cholesterol) and lifestyle modifications.
*In addition, I completed an Advance Renal Nutrition course.

I am registered with:

The Health Professions Council of South Africa (HPCSA)
The Association for Dietetics in South Africa (ADSA)
Eatfit (The dietary management of irritable bowel syndrome)
CDE OPTIFAST program, for the management of Type 2 Diabetes and Obesity
DNA’lysis, to report on DNA test results

In my spare time, I enjoy reading, going for walks and spending quality time with my husband and son.
