Program Content​
​
Course 1: Cancer, Nutrition, and the Biological Terrain
This first 10-week course is based on our Founder's book The Metabolic Approach to Cancer and explores the many different terrain-centric dietary, environmental, emotional, and lifestyle factors associated with increased cancer risk, development, and progression. Throughout this course, students will examine food from three perspectives - as cancer risk factors, as potential cancer inhibitors, and as metabolic cancer therapies. The goal of this course is for students to gain an understanding of how to apply nutrition therapy and lifestyle medicine to a myriad of internal and external cancer related factors within the biological terrain that can contribute to carcinogenesis or, ultimately, encourage prevention.
Course 2: Nutrients and Therapeutic Diet Design
This course details the role various metabolic dietary therapies, macronutrients, phytonutrients, fibers, vitamins and micronutrients play in the cancer landscape. Students will gain a deeper understanding of the mechanisms behind plant families, amino acids, lipids, and their roles in causing, preventing, and managing cancer. An introduction to several metabolic dietary therapies including the ketogenic, elimination, tube, AIP, GAPS, low FODMAPs, and TRE diets with the premise of bio-individualizing protocols to meet the ever-changing needs and side effects a client may experience. Classes on macronutrients provide guidelines around food quality considerations to maximize nutrient density and reduce toxicity.
Course 3: Nutrition Assessments and Cancer Treatments
This course details the principles, goals, and scope of practice in Oncology Nutrition Therapy. Class topics include performing and recording a proper intake, evaluation, assessment, lab evaluations, and drug-nutrient interactions. Introduction to terminology and protocols used in conventional medical settings is critical for the ONC in order to provide high value integrative consulting services. Students will gain confidence in how to safely use nutrition to support patient/client quality of life through conventional medical treatments including chemotherapy, radiation, immunotherapy, surgery, transplants, and transfusions.
Course 4: Cancer Types and Systems Based Nutrition Therapy
This course explores over a dozen different types of cancer, the associated risk factors, standard of care treatments, and evidence for systems-based nutrition and lifestyle intervention strategies. Students will learn a terrain, and systems-based framework that consists of a strategic process of targeted elimination, diet and lifestyle integrations, assessments, and safe supplementation. Students in this final 10-week course will gain mastery in viewing cancer types with a broader, terrain-centric view and the tools to safely integrate and customize oncology nutrition therapy protocols.
Final Exam
Timed, 100 Question Exam
