Who we are

Natural Nutrition

Heidi du Preez is a registered Professional Natural Scientist, who obtained her master degree in Food Science. She worked as a Food Scientist in the food industry for six years.

While living in the UK for three years, and as a Food Scientist with a personal interest in health and nutrition, Heidi started to study and specialise in natural health. During this time, through extensive research and diligently following specific nutritional practices, she healed herself of Systemic Candidiasis. Heidi has learned the value of balanced wholefood nutrition and a healthy lifestyle, and it is now her passion to share this knowledge with others.

Heidi has experience in lecturing post-graduate students and in the compilation and presentation of workshops, seminars and lectures. Heidi has appeared on TV and has written several publications on scientific and general matters. She currently writes for The South African Journal of Natural Medicine and serves on their panel of experts. She is the author and publisher of the health recipe book Naturally Nutritious Wholefood Cookbook.

Heidi is currently specialising in Functional Medicine. She is focussing on sulfur metabolism and is working towards a PhD degree. Heidi consults to both the food and health industries and runs a private practice in Cape Town. She uses a holistic, biomedical approach, incorporating diet, wholefood supplementation, detoxification and spiritual well-being in her treatment regimen. Her focus is on the prevention and cure of chronic, metabolic and degenerative diseases. Heidi specialises in digestive disorders, mercury or metal poisoning, systemic candidiasis and integrative oncology.

She does not believe in recommending or following a specific diet fad, preferring her own tailor-made health discipline, incorporating concepts which are relevant to her scientific background as well as her holistic approach. Heidi does not ‘practice what she preaches’, but rather ‘preaches what she practices’ and follows the philosophy of simplicity and returning to the basics of good food, good thoughts and good health.

Heidi is the proud mother of two beautiful and healthy children.


Camilla Howard joined Natural Nutrition in February 2015 to learn as much as possible from Health-Guru-Heidi while helping her to grow the business. In September she will graduate as a certified Health Coach from the Institute of Integrative Nutrition in New York. Camilla helped her chef Mum start the prestigious gourmet cooking school, Chez Gourmet, where her passion for creating healthy, nutritious meals grew. She is a health & fitness fanatic. Some of her recent feats include: summiting Mont Blanc, walking the entire 3600km coastline of South Africa, stand up paddle boarding the Okavango Delta, chef’ing in Antarctica and cycling through 4 countries in East Africa. She also became the first woman to summit Kilimanjaro barefoot.

Camilla advocates minimalism and thrift. Bio-individuality and Primary food are key concepts that resonate with her. Primary food is more than what is on your plate. Healthy relationships, regular physical activity, a fulfilling career and a spiritual practice can fill your soul and satisfy your hunger for life. When primary food is balanced and satiating, your life feeds you, making what you eat secondary.

She believes eating healthily is not a punishment for over indulgent habits nor is it a diet prison sentence to be endured until you can enjoy your “eating freedom” again. It is about making the decision to live a healthier life and taking small steps everyday towards improving your health for yourself and your future.
