R.H.N.s™ Registered Holistic Nutritionists™, (or, Registered Holistic Nutritional Consultants™ in the Atlantic Provinces) (or, Holistic Nutritionists™ or Holistic Nutritional Consultants™ in Alberta) are professionals trained in Natural Nutrition and complementary therapies, whose principal function is to educate individuals and groups about the benefits and health impact of optimal nutrition.

Mainstream medicine does not emphasize the significance of poor nutrition as a major cause of a wide range of health disorders. Although most people are aware of the benefits of sound nutrition, the range of conflicting information available to the consumer is often confusing. RHNs™ guide their clients through the maze of information from books, magazines, supplements and diets on the market. They work with clients to identify and help correct the nutritional causes of diseases, and they are qualified to design personalized diet and lifestyle programs that optimize health. Many RHNs™ also contribute to the health and well-being of Canadians by writing articles for prominent health care magazines such as Alive and Vitality.
