The Oncology Nutrition Institute (ONI) was founded in 2017 to provide evidence-based educational certification and training programs in the emerging field of oncology nutrition. We are a 100% online school teaching practitioners and members of the general public from around the globe about the therapeutic potential of food, therapeutic diets, micronutrients, and phytonutrients in the oncology setting. 

Our flagship, groundbreaking 250-hour oncology nutrition consulting (ONC)™ certification program is an intensive one-year training program designed for nutrition, health and medical practitioners.​

We also offer an expanding array of CEU approved trainings and programs for that vary in length from one hour to three for providers and also for members of the public looking to gain a broader understanding of how nutrition applies to the cancer process.  

Approximately 85% of all cancer cases are caused by diet and lifestyle. Food is fundamental. It can both contribute to the development of cancer and also help to prevent and manage the cancer process. The Oncology Nutrition Institute was founded to educate and illuminate what foods contribute to cancer, which may help to avert it, how food impacts the terrain, and how to customize bio-therapeutic diets from ketogenic diets to digestive specific protocols.

The information presented in our programs reference over 1,000 published studies to empower students to safely guide clients or educate themselves in therapeutic diets, micronutrients and phytonutrients. Nutrition is an effective adjuvant therapy that can enhance the effectiveness of standard treatments including chemotherapy while also helping mitigate side effects and improve quality of life - and our programs are designed as a compliment to conventional treatment.


Oncology Nutrition is not intended as a diagnosis, treatment or cure for cancer or any other disease and should not substitute regular medical care.


At the Oncology Nutrition Institute we believe that everyone should have access to safe, evidence-based, metabolically-focused Nutrition and Lifestyle approaches to help improve quality of life and risk for disease. Different foods can be powerful medicinals or toxic poisons and our school aims to train students and educate the public on the difference.
