The Oncology Nutrition Institute (ONI) provides evidence-based educational certification and training programs in the field of modern, metabolic, innovative, integrative, and outcomes-based oncology nutrition therapy. We are a 100% online school teaching practitioners from around the globe about the medicinal potential of therapeutic diets (i.e. ketogenic, TRE, AIP, Low FODMAP, tube feeding), the safe use of nutrition alongside conventional treatments, nutrient-drug interactions, assessment tools (i.e. micronutrient testing), micronutrients, phytonutrients, lifestyle techniques, nutritional psychology, and more.
Our flagship 250-Hour Oncology Nutrition Consulting (ONC) certification program is an intensive training program designed for qualified nutrition, health, and medical practitioners.​ The program consists of four, 10-week courses and a final exam. Assessments are graded, and individual feedback provided by expert instructors. Each term there are optional live Q&As, in addition to weekly reading assignments, presentations to view, and assessments to complete.
We believe that holistic, therapeutic, metabolic nutrition should be part of the standard of care. The world needs more qualified practitioners to help support clients/patients improve quality and quantity of life using dietary therapies, nutrition interventions, and lifestyle modifications. This certification program will not only enhance your practice, it also encourages students to focus on their own health. Reducing future cancer risk starts with what we eat today. Join us.

"The Oncology Nutrition Institute provides sensible, evidence-based approaches to nutritional patient care during the cancer journey. The educational experience was informative, interesting and engaging, looking at each cancer with separate protocols, highlighting the importance of ethical, safe advice. The material provided is current and peppered with exceptional guest lecturers, all of whom are world leaders in this field of therapy. I thoroughly enjoyed the assignments which cleverly built the basis of practice guidelines. A valuable course for practice."
