Four, 10-week Courses | 40 Class Topics | 100 Hour Internship | Final Exam


This course explores the many different terrain-centric dietary, physiological, environmental and emotional factors that have been linked to increased cancer risk, development and progression. Throughout this course, students will examine food from three perspectives - as a contributor to cancer, as a potential cancer inhibitor, and as an integrative cancer therapy.


The goal of this introductory course is for students to gain an understanding of how to apply metabolic nutrition therapy to the ten internal and external factors that contribute to carcinogenesis to ultimately encourage prevention. Students will also learn a comprehensive set of assessments that can help with the identification of terrain imbalances as well as aid in the monitoring of nutrition interventions that focus on both prevention and long term out-comes. 


This course explores over a dozen different types of cancer, their risk factors, current frontline treatment options, associated systems-based nutrition considerations, and dietary related research findings. Western medicine treatments and research focus heavily on types of cancer and their location in order to formulate treatment plans and drug development.


Integrative nutrition follows suit, utilizing the research of specific nutrients and dietary therapies to target specific cancer types and enhance conventional treatments. In this course students will get a comprehensive overview of the current standard of care for the major types of cancer and proven nutrition interventions that can benefit cancer types.

During this course students will gain insight into how to use nutrition to support their clients as they go through conventional medical treatments including chemotherapy, radiation, and surgery. Students will learn foods to avoid and nutrition therapy approaches to employ depending on type of treatment in order to avoid interactions and enhance quality of life. End of life discussions are also presented along with self-care strategies for the ONC.


This course details the principles, goals, and scope of practice in Oncology Nutrition Therapy. It includes the practical application of methods used by practitioners in performing and recording a proper client intake, evaluation, assessment, and intervention plan. Understanding specific terminology and protocols used in conventional medical settings is contrasted with those used in holistic settings. The overview, development, and refinement of intake forms are key course elements, in addition to understanding and practicing the SOAP note documentation format. Creating an appropriate nutrition plan for the client is crystalized.

Oncology Nutrition & Diet Design
Anti-cancer actions of nutrients and a variety of dietary interventions


This course details the role of researched therapeutic diets, phytonutrients, vitamins and micronutrients and their role in cancer therapy. Students will gain a deeper understanding of the mechanisms behind plant families, amino acids and lipids, and their roles in causing, preventing, and managing cancer.


A deep dive into therapeutic diet design, including the ketogenic diet, Paleo, autoimmune, GAPS and other therapeutic diets will be discussed under the premise of bio-individualizing therapeutic nutrition to meet the ever-changing needs and side effects clients may experience.

Internship/capstone projects are customized to the student and designed to develop, promote and enhance professional goals. Required documentation of 100 hours spent directly in the field of oncology nutrition and/or oncology-specific settings is an important educational tool for our students to have time interacting with the cancer population. Internships can be done in whatever country you live in, and can be waived for those who have worked in the field of oncology for 100 hours.
