A note from Diane

If you've recently received a breast cancer diagnosis, I think I might know a bit about where you're coming from. One minute you're living your life - working, hanging out with family and friends, cooking, laughing, running errands - and the next minute you're sitting in shock in the doctor's office after hearing 'you've got breast cancer.' You are trying to figure out the best road to recovery while dealing with a rollercoaster of emotions, and the uncertainty is so scary. As a Holistic Nutritionist in cancer care and recovery, I'd like to offer you some hope and some help.

"You are not alone. There is a path. There is a plan."

Glossary - what these credentials mean

Most clients have never heard of RNCP or ROHP. Here's what the letters stand for, and how Diane's training fits the work.

What does Registered Orthomolecular Health Practitioner (ROHP) mean?

"Orthomolecular" comes from two Greek roots - "ortho-" meaning correct or proper, and "molecular" meaning at the molecular level. The term was popularized by chemist Linus Pauling in 1968 to describe the use of nutrients the body already needs (vitamins, minerals, amino acids, essential fatty acids) at the levels the individual person needs them, to support health. A Registered Orthomolecular Health Practitioner (ROHP) is trained to assess a client's specific situation and recommend whole-food and supplemental nutrient strategies tailored to that individual - not generic dosages, not a one-size-fits-all multivitamin. The ROHP designation is registered through the International Organization of Nutritional Consultants (IONC).

What does Registered Nutritional Consulting Practitioner (RNCP) mean?

A Registered Nutritional Consulting Practitioner (RNCP) is a Holistic Nutritionist credentialed through the International Organization of Nutritional Consultants (IONC). The training covers anatomy and physiology, nutrient biochemistry, therapeutic foods, supplementation, and lifestyle counselling - with a focus on whole-food, individualized care. Diane earned her RNCP through the Institute of Holistic Nutrition's two-year diploma program (2007-2009).

What's the difference between RNCP and ROHP?

They're companion designations registered through the same body (IONC). RNCP focuses on the whole-foods and lifestyle side of nutritional consulting; ROHP adds the orthomolecular layer - the science of using specific nutrients at therapeutic levels to support the body. Practitioners who hold both, like Diane, are trained to work across both lenses simultaneously.

Is a Registered Holistic Nutritionist the same as a Registered Dietitian?

No - these are distinct credentials with different scopes. A Registered Dietitian (RD) is a regulated health professional in Ontario, governed by the College of Dietitians of Ontario under the Dietetics Act. A Registered Holistic Nutritionist works under the RNCP/ROHP designations through IONC; "nutritionist" is not a protected title in Ontario. Diane is a Registered Holistic Nutritionist, not a Registered Dietitian. Her work is complementary to - not a substitute for - care from your physician, oncology team, or RD.

Is Diane a doctor?

No. Diane is a Holistic Nutritionist, not a physician or naturopathic doctor. She does not diagnose disease, prescribe medication, or treat cancer. Her role is to support your nutrition and lifestyle alongside your oncology team's treatment plan - through education, meal planning, therapeutic recipes, and supplementation guidance grounded in research.

Will Diane work with my oncology team?

Yes - and she expects to. Diane's protocols are designed to complement standard oncology care, not replace it. Anything she recommends is meant to be reviewed with your medical team, and she'll always ask what your team has advised before suggesting changes to your diet or supplements.
