@ Health Dieetkundiges Centurion

I have the privilege of raising four wonderful children. Nutrition has provided me with so much knowledge to live and be more healthy as well as to always stay on top on new trends and changes in my field. As dietician I am also very involved in genetic testing to empower my patient with knowledge as genetics can help a person to regulate their health much more directly based on a person’s individual outcome.
I also completed a 2 year post graduate diploma through the International Functional Nutrition Academy. Furthering my studies is an wonderful tool to always provide patients with the best up to date knowledge.
I am a firm believer that being healthy empowers people and that this can be absolutely achievable.

From a young age I have also been amazed at the intricate working of the human body and when I put these two passions together, it changed my life.
My vision in my profession is to inspire people to shift their paradigm from kilograms and calories and to help them use food to optimise their health. My interest in the science of using food as medicine has become the core of my nutritional approach. More and more research is emerging showing that every wellness journey is unique and I strive to offer an individualised service to each and every one of my patients.
I love working with lifestyle conditions but really I just love working with people. That is what fuels my love for this profession.

I have a special interest in lifestyle, gastrointestinal and hormone related conditions with a functional nutrition approach in which we focus on also treating the origin of the problem and not only managing the symptoms.
We all know that food plays an important role in your overall health but everyone is not aware of the most effective and sustainable methods to use, considering a large amount of unsubstantiated advice doing the rounds. Therefore, my passion lies in making the unknown and uncertain field of nutrition known to my clients by providing individualized and realistic education by equipping my clients with tools to make healthier decisions for a lifestyle change. As healthy living is a lifestyle and not a quick fix.
I believe that food is powerful and has an enormous impact in every individual’s daily life. I take great pleasure in experiencing the client’s change in mindset and walking the journey, hand in hand to a healthier lifestyle.

I have a special interest in cardiovascular diseases, specifically fibrinogen concentration and formation, diabetes (CDE accredited practitioner), renal disease, nutrigenetics, premature infants and enjoy working with both the adult and paediatric population. Nutrition is a constant changing field and I enjoy learning and growing with new trends and changes, I believe it is very important to know and understand the latest research to provide holistic care. I believe that nutrition is the core element that can prevent and control many health problems and not everyone is aware of disease prevention through nutrition.
Today as a registered dietician I want to help others forget about the word “diet” and replace it with positive, sustainable lifestyle changes. I aim to inspire people to feel as good as they can through food and to help them achieve their goals.

This quote, credited to being said by Hippocrates thousands of years ago, is a concept that I firmly believe that we should all live by today.
I consider what we eat central to achieving good health and wellbeing and I am passionate about translating the sciences into practical and sustainable lifestyle habits that can help optimise health. I often experiment with different types of foods and cuisines (stop the stigma of healthy food being rabbit food!) and enjoy adapting it to individual eating habits and preferences that everyone can enjoy.
I am currently studying a post graduate diploma in Performance Nutrition through the Institute of Performance Nutrition (UK), and, naturally, my special interests lay within sports and performance nutrition, as well as inflammatory and auto-immune conditions, hormonal disorders such as PCOS, chronic diseases of lifestyle such as diabetes and cardiovascular disease and finally, weight and body composition management.
I love working with people in providing unique, individualised approaches to reach their goals and ultimately become the best versions of themselves!
