"Teaching the Medicine of the Future" Since 1994, the Canadian School of Natural Nutrition has been Teaching the Medicine of the Future. The success of our wonderful enterprise reflects the societal changes that are leading us, slowly but surely, to greater self-responsibility in health care. Wholesome nutrition is indisputably the cornerstone of good health. CSNN is the first school in Canada to offer classroom studies in holistic nutrition, and our commitment to quality education has resulted in CSNN being the largest, leading school in holistic nutrition education, offering both classroom and correspondence studies. CSNN offers a comprehensive practical foundation program in Natural Nutrition leading to the Registered Holistic Nutritionist (R.H.N.) designation, plus a diploma program in Advanced Holistic Nutrition with the option to take individual workshops and earn Continuing Education Units.
